The use of centrifugal disk fertilizer spreaders, the axes of which are set obliquely, in the technological process of mineral fertilizers provides an increase indicators characterizing the spreading of technological material in the direction of its scattering, at a greater distance than fertilizer spreaders with vertical axis of rotation. Thus, the hypothesis of the possibility of increasing the working width of the machine for applying mineral fertilizers by equipping such machines with centrifugal disk fertilizer spreaders, the axes of which are set at an angle, is confirmed. Experimental research was conducted using the developed methods and current state standards, regression analysis, statistical methods of processing research results, standard and specially designed experimental equipment. The calculations were performed using the software environment Microsoft Office Excel 2007. As a result of experimental researches it is established that the centrifugal disk fertilizer spreaders which axis is placed inclined, reliably provides performance of technological process at change of frequency of rotation of its disk from 600 to 1000 rpm and changing the angle of installation of the disk to the horizon from 0o to 30o. For all studied kinematic modes of operation of the new working body, the effective scattering range of mineral fertilizers and the distance from it to the tray with the maximum share of the mass of sown fertilizer increase most rapidly with increasing disk angle to the horizontal plane from 0o to 10o, and least when changing the angle within 20o - 30o. The best indicators of fertilizer application both in terms of working width of capture and in terms of uneven application of fertilizers are provided at the angle of inclination of the disk of the new working body to the horizontal plane within 25o-30o.

The technological processes of cold rolling of precision workpieces and ring parts, rolling of pipes, rolling of piston-connecting rod axial-rotor piston pump, which are a kind of processing of metals by pressure and contain changes in the shape of workpieces according to performing relative to the axis of the workpiece radial rotational motion. The workpiece can remain stationary or rotate.
It is shown that by means of technological process of rolling of pipes, unrolling of preparations various hollow axisymmetric metal products receive, the specified processes are combined by the mechanism of deformation, namely: at them two deformations of compression and one - tension are realized. This mechanical deformation scheme creates favorable conditions for plastic deformation, because intercrystalline displacements are difficult, leading to the violation of mechanical bonds, and plastic deformation occurs mainly due to intracrystalline displacements.
It is shown that in the process of connecting the piston-connecting rod in compliance with the process parameters (output supply pressure, feed rate, leaving time) the value of the specified gap either exceeds the maximum value or decreases to the value at which the next operation of the piston-connecting rod spell.
The deformed state in the technological operation of rolling the piston-connecting rod pair at different stages of shape change is studied, the process control mechanism is revealed, which prevents the defect in the form of deviation from the regulated gap after rolling between the piston and the connecting rod.
The used resource of plasticity at different stages of rolling is calculated, the deformability of the piston workpiece in the rolling process is estimated.

The article presents the results of the development of processes to improve the performance of parts operating under repeated variable loads, taking into account the reasonable parameters of surface plastic deformation (SPD) and cold gas-dynamic spraying of coatings. The influence on the parameters of the working surface layer, the nature of the distribution of the stress-strain state of the surface layer of material and residual compressive stresses, as well as the values of the used resource of plasticity of the surface layer of the workpiece, the parameters of the SPD process. The article shows that the main factor in the formation of residual compressive stresses during SPD is the decrease in the density of the surface layer of the workpiece, which is associated with the use of the plasticity resource. The model of calculation of the used resource of plasticity of material of preparation at SPD which allows to provide the improved quality of a surface layer of details is offered. A method of moving the workpiece layers with maximum hardening and residual compression stresses to the surface of the part by applying a deforming tool of reduced size in the following passes with coating the surface of the part with gas-dynamic spraying before SPD.
Cold gas-dynamic coating by spraying, in contrast to most known gas-thermal coating methods that take place under significant temperature effects on the surface of the part, which is unacceptable for surfaces treated by SPD methods, provides a permissible temperature regime for creating special auxiliary coatings while preserving surface properties SPD.
The technology of gas-dynamic coating by spraying includes heating the compressed gas (air), directing it into the nozzle and forming in this nozzle supersonic air-powder flow, sprayed material (copper, aluminum), acceleration of this powder material to supersonic speeds and directing it to the surface of the processed product. As a result, a special auxiliary coating (copper or aluminum) is formed on the surface of the product, which improves the parameters of the SPD process.

Increasing the level of semiconductor devices, improving their characteristics significantly affects the potential stability in a wide range of frequencies. Classical methods and standard measuring equipment are not designed to measure the parameters of potentially unstable transistors. Measuring systems are excited uncontrollably, which increases the measurement error. Therefore, today there is an urgent task of measuring the parameters of both transistors in particular and quadrupoles in general, in the frequency range of potential instability.
The clock frequency at which modern computer equipment works is close to the microwave range (ultrahigh frequencies), which makes the problem of measuring and calculating the various functional units of the computer quite relevant.
The development of new methods and means of measuring the parameters of potentially unstable quadrupoles in the microwave range is an important scientific field that can significantly improve the accuracy of their measurement on standard equipment.
The conducted researches and the developed technique allow to increase accuracy of measurement of parameters of four-poles and to provide stability of experimental installation at measurement of parameters of any four-pole. The proposed methods are more efficient and solve the problem of measuring the S-parameters of potentially unstable quadrupoles in the microwave range.
The parameters of the quadrupole have the dimensions of the elements of standard W-parameters, their measurements are performed in the microwave range with an error of less than 5%, and to a lesser extent depends on the coefficient of stability of the measuring path than when measuring S-parameters.
When measuring the parameters of the quadrupole, there is no need to use the modes of short circuit and XX or make measurements with a coordinated measuring path, which allows to increase the measurement accuracy and ensure stability when measuring potentially unstable quadrupoles with Ks> 0.

As the result of the analysis, mathematical modeling and determination of critical conditions of existence of the system have been carried out. The basic criteria and tolerances for the normal operation of FPS equipment have been determined. The calculated dependencies for the further improvement of the system and the parameters for the smooth operation of the equipment by means of a mathematical analysis have been found. Methods of test planning of operability of FPS equipment have been developed, the time frame of stopping various systems for the slightest l ss of production capacity, taking into account the duration of the diagnostic work of used equipment has been determined. The planning of inspections for a product that is in a state of readiness for action, possible only after replacement, is considered. These circumstances allow us to determine the optimal interval between inspections by the criterion of minimum expected costs, attributed to the average time of serviceability for the cycle in steady state. When planning inspections of a product that is in a state of static readiness for action, the possibility of making erroneous decisions during the inspection is taken into account. The products which start to act at occurrence of some emergency conditions which moments of occurrence are casual and have distribution W (t) are considered. It is determined that inspections and necessary repairs allow to increase readiness, if at the same time certain conditions concerning quantitative ratios of the sizes influencing it are fulfilled.

Published: January 2021

The analysis of modern existing methods for producing internal thread showed that one of the most promising methods, with significant technological capabilities and high productivity, is the method of plastic shaping (extrusion) of the thread with chipless taps.
The complex of known measures aimed at increasing the stability of taps and their reliability, consisting in the creation of new tool materials, improvement of the design and optimization of the geometry of the cutting part of the taps, improvement of the quality of working surfaces, the use of new types of cooling and optimal settings, do not solve the final issue of high performance and high quality manufacturing of thread holes in stainless and heat-resistant steels not only on highly automated equipment, but even on conventional ones.
It is substantiated that the most widespread are taps with a conical full-profile intake part; distortion of the pitch ΔР at he tops of the turns in the transition zone is one of the main design disadvantages of chipless taps. A diagram of the formation of a thread profile by chipless taps with a conical deformation pattern is presented. It is proved that the geometric incompatibility between the thread profile of the tap and the thread formed by it is one of the main reasons for the chipping of the tops located in the transition zone and a sharp increase in the torque of the thread extrusion The parameters of chipless taps are optimized and the advantages of their use in the process of thread extrusion are determined.
The main objectives of the research: to investigate the power features of the process of manufacturing threaded holes with chipless taps in stainless steel parts in order to develop optimal designs of taps for through and blind holes; to develop a technological process for the manufacture of chipless taps of the necessary technological equipment for a grinding machine, as well as for grinding the threaded profile of taps.

Published: January 2021

For Ukraine's successful entry into Western markets, it is necessary to ensure the competitiveness of its own products, which is achieved through comprehensive mechanization of technological processes, reducing labor costs, increasing yields and quality of products.
The most common method of mechanized potato harvesting is undermining the tuber layer with its subsequent destruction and separation of tubers from the heap, which contains plant impurities, soil lumps and stones. The most difficult is the separation from the tubers of strong soil lumps and stones. Attempts have been made to overcome this problem by placing potatoes on well-sifted sandy soils, using special agronomic techniques that reduce, to some extent, the number of lumps. However, such measures are local in nature, not reliable enough and significantly complicate the technology. About 25% of the area occupied by potatoes is heavily littered with stones, the size of which is close to the size of tubers, and about 40% of planted potatoes are placed on soils prone to significant lump formation.
Accordingly, the aim of the study was to conduct a comparative analysis of technologies and machines for harvesting potatoes, to develop a model for cutting a potato heap with a ploughshare blade.
The research was carried out by technological and structural analysis of technologies and machines for harvesting potatoes. In the process of research methods of comparison and mathematical modeling of technological processes were used. The information base of the research was the work of Ukrainian and foreign scientists on technologies and machines for potato harvesting.
On the basis of the comparative analysis of technologies and machines for potato harvesting the main processes influencing agrotechnical indicators of harvesting equipment are revealed, the model of cutting of a potato heap by a ploughshare blade and other constructive and kinematic parameters of working bodies of a ploughshare blade is developed.

Authors: Naduty Vladimir , Sukharev Vitaliy , Kostyrya Sergey
Published: January 2021

Great difficulties arise when processing wet mineral raw materials less than 1 mm, and this problem is given large attention. There is an urgent need to dehydrate the final product of mining to a minimum percentage of moisture. Such raw material includes coal, which in the process of mining and processing forms a large number of small particles with a size of 1.0 ÷ 0.05 mm and, when enriched by froth flotation, is saturated with moisture, which complicates the subsequent use of coal. Also, for the processing of man-made deposits, consisting of ash and slag waste, they must be dewatered for subsequent complex processing, which consists in the use of magnetic separation and fine screening.
Mechanical dewatering devices do not always provide the final moisture content required by the market today. Only free and loosely bound moisture is extracted by mechanical methods, and pore and capillary moisture is not removed. Therefore, various sources of heat are used as an auxiliary process for the dehydration of minerals.
The article presents the results of studies of dehydration of finely dispersed rock mass on a vibration device of a new design. Intensification of the dewatering process is achieved due to the vertical conical screw and the creation of a vibroboiling layer. Preliminary studies have shown the effectiveness of the use of a transport-drying device, while it was possible to reduce the humidity in the finished product from 15% to 5%.
According to the results of the experiments, it was found that during the operation of the transport-drying device, the layer thickness decreases from loading to unloading by 3 times, while the path of movement of the material along the working surface increases 2.5 times, the frequency range of vibration excitation from 1000-1200 rpm, the amplitude fluctuations are 4-5 mm and the temperature of the supplied air is 50-80 Сº. Thus, the proposed dewatering device can be used in the mining industry, since, in addition to transportation, it is also capable of dewatering wet material with sufficient efficiency.

Published: January 2021

This section presents the results obtained after processing the provisions using SolidWorks. Schemes of loading of a nut with pressure and the modulus of resistance on a ring are presented, the general kind of a nut with its distribution in two-dimensional finite elements is presented, graphs of correlations between the stresses and strains appearing in a nut shell depending on force acting are established. and undeformed walnut shell and it was presented that the initial crack appears at the junction of the halves of the nut shell.
Today, walnut is one of the niche crops. Only 7% of the land on the planet is suitable for growing nuts, and Ukraine is one of the few countries where the entire territory is suitable for cultivating this crop. According to statistics, in 2019 the area of walnut plantations in Ukraine amounted to 15.8 thousand hectares, of which 85.4% are concentrated in private households and they provide 99.2% of the production of this product. But this factor affects the unstable supply of this crop, as it is difficult to form commodity batches of different varieties of nuts, as well as narrows the range and reduces its cost. The annual consumption of nuts in Europe and the Persian Gulf is 4.2-5.6 kg per person, while in Ukraine the figures are more than modest - only 1.8-2.4 kg, at normal (according to the Institute of Nutrition of the Ukrainian Academy of Sciences ) from 1.5-3.6 kg.
Walnuts are the most popular and beloved. They are not only very tasty, but also very useful. Due to the content of binders, walnut is a good anti-inflammatory agent. Extracts and nut preparations have antitoxic effects, remove various toxins from the body, as they say, cleanse the blood.
The work related to the process of modeling the deformation of the nut shell is very relevant. The obtained results can be integrated into the work of the nutcracker for greater efficiency, which will allow to obtain a better quality product
COMPUTER SIMULATION OF THE PROCESS OF STAMPING BY ROLLING CYLINDRICAL AND PIPE PREPARATIONS USING THE DEFORM - 3D SOFTWARE COMPLEX
Authors: Shtuts Andrii
Published: January 2021

The purpose of modeling is the analysis of the stress-strain (VAT) [7,14] condition and deformation of tubular, cylindrical workpieces in the deformation process, determining the energy parameters of the process, as well as the geometry of the deforming tool. transverse and longitudinal directions, as well as the cleanliness of the surface of the profiled cavity.
This article analyzes the features of local deformation, which define stamping by rolling as an independent type of metal pressure treatment in the metalworking industry. This problem is most effectively solved by using cold plastic deformation processes, which allow to bring the shape of the workpiece as close as possible to the shape of the finished product, and in some cases eliminate the need for further processing. Using the method of cold deformation instead of cutting, you can increase 2… 3 times the utilization of the metal. This ensures high quality of the workpiece surface, improves the physical and mechanical characteristics of the material, increases productivity and creates conditions for full automation of production. Examples of the most complete realization of advantages of stamping by rolling that provides efficiency of industrial use are resulted. In the priority areas of science and technology, a special role is given to energy and resource conservation.
In [3] the simulation results for rolling stamping without restriction with one-sided and two-sided restriction of metal flow along the length of lead blanks are presented.
Analysis of the experimental study showed that the process of stamping rolling (SHO) workpieces with conical and cylindrical rolls, allows you to control the flow of workpiece material by changing the size and direction of the axes of the workpiece roll, relative to the direction of rotation of the workpiece. The conducted modeling of SHO processes showed that the stress-strain state, deformation and deformability of the workpiece material also significantly depend on these parameters.
The technological capabilities of the SHO are limited mainly by the loss of stability and destruction of the workpieces, which, in turn, significantly depends on the direction of flow of metal at the contact of the roll with the workpiece.
Thus, the ability to control the direction of flow of the metal largely determines the ability to manufacture workpieces of the desired shape and size without destruction and loss of stability [2].

Published: January 2021

The analysis of the work of tillage machines is carried out, the reasons for the failures of their working bodies (plowshares) during operation are revealed.
Research has been carried out on the change in the characteristics of the material of the cutting elements of soil-cultivating machines after vibration hardening, as well as the effect of hardening on the strength of restored plow shares. The parameters of vibration hardening of plow shares are experimentally determined.
Microstructural studies were carried out in order to reveal the influence of the processing method on the properties of the plowshares material. Criteria for the limiting state of plowshares are revealed. Bench tests of plow shares at the installation allow you to adjust the intensity of their wear.
It has been established that the depth of wear of the ploughshare material is the most significant geometric parameter affecting its resource.
Experimental studies have established the values of the main parameters of vibration hardening: the frequency and amplitude of oscillations of the working working tool and the hardening time. The values of the degree of hardening of the material of the cutting edge of the reconditioned plow shares have been determined.
The relationship between the values of the change in the width of the ploughshare and the thickness of its blade during deformation has been established. It was found that, in addition to the processing modes, the shape of the processing tool affects the geometry of the share. An uneven wear pattern along the length of the share is revealed.
The results of changes in the wear along the width of the cutting element and the intensity of its wear depending on the operating time are given. It has been established that the amount of wear of the plowshare cutting element depends on the technological modes of processing and the material.
Conducted bench studies of the specified variants of plowshares in order to check the operational reliability of the restored and vibration-hardened plow shares. It was found that the plowshares made of 65G steel, treated by vibration hardening, had the lowest wear rate, which is explained by the change in the structure of its material during vibration hardening.
POST-IMPACT VIBRATIONS OF A SQUARE NONLINEAR DISPATIVE OSCILLATOR

Published: January 2021

An oscillator damped by viscous linear resistance, due to the instantaneous increase in its mass after impact, can become a dissipative oscillatory system under the action of dry or positional friction. In the article describes the oscillations of a dissipative oscillator with an asymmetric quadratically nonlinear elastic characteristic and dry Coulomb friction, arising as a result of an inelastic vertical impact of a rigid body on it. In the article, the Cox model is used, which does not take into account local deformations of solid bodies subjected to impact. The paper establishes the dependences on the impact velocity and the values of other parameters at which the effect of asymmetry of the elastic characteristic of the system may appear or may not appear. The conditions are derived when the dynamic effect of asymmetry of the power characteristic is manifested in the system. It consists in the fact that the maximum displacement of the oscillator (oscillation range) in the direction of the shock pulse is less than the opposite extreme displacement (range) after the shock oscillations. The existence of such a critical value of the shock impulse is established, the excess of which leads to the loss of motion stability. The second integral of the oscillation equation describes the movement of the oscillator in time, expressed in terms of Jacobi elliptic functions. An approximate formula for their calculation is proposed. Formulas are also derived to determine the time to reach extreme deviations of the system from the equilibrium position. This time is expressed in terms of elliptic integrals of the first kind, which refer to the tabulated functions. Examples of calculations are considered, where, in addition to using the derived formulas, numerical computer integration of the original nonlinear differential equation of motion is carried out. A comparison of the results obtained for the displacement values of a quadratically nonlinear oscillator with dry friction expressed in terms of Jacobi elliptic functions and obtained by numerical integration is carried out. Good consistency of the calculation results in two ways confirmed the adequacy of the obtained analytical solutions of the nonlinear Cauchy problem.

Published: January 2021

The article considers the directions of increasing the efficiency of vibrating technological machines. The processing of information on the development of vibration technologies is quite diverse and is represented by numerous scientific and technical developments related to improving the efficiency of vibration machines and ensuring the reliability of their work. The analytical basis for previous research in the creation of new technology are mathematical models that reflect the properties of mechanical oscillatory systems with several degrees of freedom, which perform small oscillations under the action of a system of periodic external perturbations that create vibration fields of one configuration. The dynamic properties of the working bodies of machines in a detailed form are revealed as the distribution of the amplitudes of oscillations of the points of the working bodies. In many cases, this distribution is linear, which is due to the manifestations of the properties of the simplest movements of the working bodies. Approaches are proposed in which the possible structural mathematical modeling is realized on the idea that a linear mechanical oscillatory system with concentrated parameters and several degrees of freedom can be compared with the structural scheme of the automatic control system. Particular attention is paid to the study and evaluation of the possibility of new dynamic effects associated with the simultaneous action of several working bodies of machines, as well as - modes of dynamic damping of oscillations. An important role in ensuring such developments is played by areas of research focused on the development of methods of mathematical modeling. Based on the research it is shown that the vibration field of the vibrating technological machine is formed under the influence of several factors, which are determined by the simultaneous action of several force perturbations, asymmetry of inertial and elastic properties of the mechanical system, the presence of additional connections. The introduction of additional links in the structure of the mechanical oscillating system of the vibrating machine, can significantly affect the structure of the vibration field, providing the choice of conditions for rational organization of the technological process of vibration processing, such as vibration hardening, crushing, transportation, screening.

Published: January 2021

In this work, vibrations were investigated during loading and unloading operations of mobile agricultural machines, which are considered to be one of the most labor-intensive components of the transport process. Therefore, idle machines during carrying out operations and in anticipation of them remain quite significant, which is due to the insufficient level of mechanization of loading and unloading of cargoes on transport, with a fuzzy coordination of actions of different organizations during the overloading of cargoes at transport nodes and for some other reasons.
The main means of mechanization are stationary and gantry cranes for containers, heavy loads and large packages, as well as means of mechanization on the railway or on the chassis of a standard mobile car or special chassisIn our opinion, the use of hydraulic impulse actuators in the production of vibration and vibration shock unloading devices, which is due to simplicity of design, compactness, high energy intensity, a wide range of regulation of operating parameters and the ability to work in an automated mode is promising. In particular, a promising area is the creation of removable attachments with hydraulic impulse drive for dump trucks, onboard vehicles, tractor trailers and other vehicles.
For intensification of processes of unloading of a body of a trailer-dump truck of tractors the hydraulic vibrating shock device is developed. It accelerates the unloading and cleaning of the body of agricultural products. Reduced costs and reduced oversized idle tractors with unloading trailers.
Therefore, the development of vibration and vibration impact equipment for use in loading and unloading operations on mobile agricultural machines and in general on transport is an urgent task.

Authors: Paladiychuk Yuriy , Kordonsky Vasyl
Published: January 2021

The mechanics of chip fracture when cutting the allowance of pre-divisible technological grooves was studied for the first time, and the relationship between the profile and depth of the latter and the characteristics of the stress-strain state in the chip formation zone (relative shear, chip shrinkage, shear angle, front angle, contact processes . This article discusses a more complex problem - the longitudinal division of chips or allowance. Most researchers are inclined to believe that this problem should be solved by pre-dividing the allowance by a network of special chip-splitting ring or screw grooves. The depth of these grooves should be 0.6… 0.95 of the amount of rise on a single tooth of the broach. The results of the study of the mechanics of chip destruction are described when the tool meets the process groove in the drawing process. The connection between the structure of the pipe and the intensively deformed state in the zone of chip formation is shown. From the obtained results the following follows. Preliminary deformation hardening by means of deforming drawing allows to increase hardness of OM twice (steel 10), to 60% (steel 35), to 50% (steel 45) and to 25% (aluminum alloy AK6). This significantly reduces the shrinkage coefficient of chips (respectively 2; 1.4; 1.4 and 1.3 times) and the actual previous angle (at a sharpening angle γ = 15⁰, respectively: from 36⁰ to 18⁰; from 25⁰ to 17⁰; from 21⁰ to 16⁰ and from 22⁰ to 17⁰). All this indicates a decrease in the intensity of the cutting process with increasing intensity of the previous HPD The following minimum values of the groove profile angle for the investigated materials 2φmin were determined: 80⁰ (steel10); 60⁰ (steel 35); 50⁰ (steel 45 and alloy AK6). It is established that the minimum depth of the chip-splitting groove hC is determined from the condition of chip destruction when the tangential stresses in the shear zone are exceeded above the shear resistance of the processed material. The following values of the minimum depth of the chip-splitting groove for the studied materials were obtained: hCmin = (0.4… 0.55) Sz - steels 35 and 45; hCmin = (0.55 (0.6) Sz - AK6 alloy.

Çalışmanın amacı, kültürel değerlerimizin yeni kuşaklara ulaşmasını sağlayan huzurevindeki yaşlıların
yaşam tecrübelerinden hareket ederek özel yetenekli gençlerin sosyal gelişimlerine katkı sağlamaktır.
Çalışma sayesinde huzurevindeki yaşlıların “moral” olarak güçlenmelerine ve yaşama tutunmalarına
katkı sağlanacaktır. Çalışma nitel yaklaşımı kapsayan olgubilim deseni ile yapılandırılmıştır. Olgubilim
araştırmalarında başlıca veri toplama aracı görüşme ve gözlemdir. Çalışmanın yapısı gereği “katılımcı
gözlem” tercih edilmiştir. Çalışma evreni kolay ulaşılabilirlik göz önünde bulundurularak Samsun ili
İlkadım ilçesindeki bir huzurevi ve Samsun ili İlkadım ilçesinde özel yeteneklilerle eğitim yapan kurumdur.
Bu evrende etkinlikler huzurevi sakinlerinden sekiz ve özel yetenekli bireylerden beş gönüllünün
katılımıyla gerçekleştirilmiştir. Çalışma gönüllü özel yetenekli beş birey ile üç kere huzurevi ziyaret
edilerek yapılmıştır. Araştırmacılar katılımcı gözlem tekniğiyle etkinliğe dâhil olmuştur. Etkinliklerde
veriler ses kaydı ve olay anında gözlem formu doldurularak toplanmış daha sonra deşifre edilmiştir.
Nitel veriler “Betimsel Analiz” kullanılarak analiz edilmiştir. İki ana tema belirlenmiştir; birincisi, iyilik
yapan iyilikle karşılaşır; ikincisi ise, arkadaşlık ve önemidir. Çalışma sonucunda huzurevindeki yaşlıların
yaşam tecrübelerini dinlemek, özel yetenekli bireylerin yaşadıkları iyi-kötü olayları tekrar düşünmesine
neden olmuştur. Yaşlıların eski ve yeni arkadaşlık ve iyilikten vazgeçmeme konusunda aktardığı kültürel
değerler özel yetenekli bir eylerin sosyal gelişimlerine olumlu katkı sağlamıştır .

Pada saat praktek untuk menentukan efisiensi bahan bakar dengan menggunakan pompa injeksi dan pompa bahan bakar mekanik, ditemukan abnormality terhadap salah satu pompa bahan bakar. Dengan kejadian tersebut menarik untuk dilakukan penelitian. Penelitian ini bertujuan menentukan tingkat efisiensi antara pompa bahan bakar untuk kendaraan jenis injeksi dan jenis mekanik. Dan merekomendasikan pompa mana yang ideal untuk dipergunakan pada kendaraan. Metode penelitian ini menggunakan dua sampel dari pompa yaitu jenis injeksi yang bekerja dengan mendapatkan daya listrik dan jenis mekanik yang bekerja berdasarkan hasil dari putaran mesin yaitu dari putaran camshaft.  Kedua jenis pompa bahan bakar tersebut akan dibandingkan dengan metode pengumpulan data dan pengukuran yang dilakukan secara langsung. Untuk pompa jenis injeksi dipergunakan pompa bahan bakar yang ada pada kendaraan jenis EFI yaitu avanza 1.3 G. Sedangkan jenis pompa bahan bakar mekanik dipergunakan simulator kijang grand seri 5 K. EFI (Electronic Fuel Injection) adalah  sistem bahan bakar yang mengandalkan pompa elektrik yang diatur oleh sensor atau dimana pengontrolan campuran udara dan bahan bakar dilakukan secara elektronik. Pada jenis ini campuran bahan bakar dan udara selalu sesuai dengan kebutuhan motor bakar, sehingga didapatkan daya motor yang optimal dengan pemakaian bahan bakar yang minimal serta menghasilkan gas buang yang ramah lingkungan. Dari hasil pengetesan tersebut dengan menggunakan 2 tipe pompa bahan bakar didapatkan hasil bahwa yang lebih efisiensi adalah menggunakan pompa bahan bakar injeksi berkisar 15 Psi atau 130,420 kPa (Mekanik) dan 310 kPa (Injeksi).
