The efficiency of heating the gasoline engine while working in cyclic mode: acceleration - coasting
Authors: Bulgakov S A , Voronin D M 
Published: November 2019

AbstractThe article provides a rationale for a way of increasing the efficiency of the engine post-launch by transferring it to the “free acceleration-coasting” operating mode. The method allows to download the coupling and engine parts by means of inertial forces arising while working on non-braking unsteady speed modes, which significantly increases the efficiency of the post-start heating of internal combustion engines in relation to the steady-state idling. A comparative assessment of the run-out of parts of the main details of the major coupling of the ZMZ-4062.10 gasoline engine during the start-up period in the dynamic capacity mode and at idling is given. It remains completely acceptable and by no means can be considered threatening. It is worth noting that the application of the method is accompanied by an increase in efficiency due to the reduction of the warm-up time and fuel consumption, which makes it reasonable to consider it acceptable for use in automobile operation conditions.
Experimental study of metrological properties of magnetostrictive sensors when changing their design parameters
Authors: Yan’kov O S , Chernyshkov A S , Kornyakov M V , Gilev A V 
Published: November 2019

Abstract
This paper outlines the study of the causes of the relative error Δ in braking-force metering FT
using the noncontact magnetostrictive method. The study has been carried out on the roller brake testers used for monitoring a technical state of a vehicle brake system. The authors suggest that the metering error Δ depends on the gap δ
C
formed between the measuring and magnetizing coils of the sensor and the surface of the shaft on which the magnetostrictive sensor is mounted. Based on this assumption the experimental study is conducted to reveal the dependence of the relative error Δ of the gap δ
C
that produce a shaft beat δ
max
inside the sensor. The results of the study indicate that when the shaft δ
max
= 0.2 mm, the metering error of brake force is Δ = 1.4 %. The given value of the relative error Δ of the braking-force metering does not exceed the maximum permissible value Δ = ±3%. When the shaft beat δ
max
increases inside the sensor, the relative error Δ also increases.
Improving design safety of tractor-trailers by upgrading towing couplers
Authors: Stroganov Yu N , Yu Stroganova O , Ognev O G 
Published: November 2019

Abstract
One major way of increasing efficiency in production, construction and agriculture industries is to use motor- and tractor-trailers for transportation needs. At the same time, a tractor-trailer is a complex and less maneuverable machine in comparison with a single vehicle. Exceeding the velocity regime, especially in the case of tractor-trailers, leads to a loss of stability during linear motion, on curvilinear sections of the trajectory or in complex traffic conditions. Speed limit is a standard prevention method; however, it does not guarantee any acceptable result. Other ways of resolving this issue have almost exhausted their potential. It should be noted that solving this problem is further complicated by a lack of a unified road-movement theory for tractor-trailers – thus, mainly restrictive measures are used. The authors suggested a hypothesis on possible improvement of tractor-trailer safety by means of increasing their motion stability via upgraded design characteristics of towing tractor-trailer couplers. The higher stability would be achieved by raising the damping factor of transverse oscillations by applying lateral disturbing forces. The authors proposed over 55 technical solutions, all protected by certificates of authorship in engineering, of upgrading the towing couplers and providing the increase of tractor-trailer operation safety in various road conditions.

Published: November 2019

Abstract
In the modern conditions of the Russian Federation in the traffic management field one of the priorities is the development and improvement of the route transport functioning quality. One of the main passengers’ requirements is the minimum travel time expenditures. Satisfying such a requirement without the mutual coordination of transport processes on routes and the use of roadside station by vehicles and passengers is problematic due to their interdependence. The problem of such coordination is inherited both in the cities, and in regional settlements. In this study, a methodology has been developed for coordinating bus schedules on regional routes that have common route sections or roadside station. This methodology was implemented in the Sargatsky district of the Omsk region. According to the obtained results, the average passenger waiting time in the case of a switch was reduced by 37%.

Authors: Puzakov A V 
Published: November 2019

Abstract
The urgency of the problem under study is caused by the imperfection of methods for diagnosing automotive alternators, which do not reveal hidden defects, as a result of which the alternator failure is sudden and entails costs due to vehicle downtime in repair. The aim of the study is a method for predicting the residual life of automotive alternators, built on the results of diagnosing and assessing the operating conditions of a car, for the first time considering the magnitude of the fluctuation of the output voltage. Analytical expressions describe the dependence of the intensity of an alternator resource on the ambient temperature and operating time, considering its technical condition at the time of diagnosis and the degree of its change under the influence of factors operating conditions on the test run. The theoretical results were confirmed by experimental measurements. The presented results can be used for the full implementation of the life of automotive alternators in the conditions of road transport enterprises.

Authors: Spirin I V , Yu Matantseva O , Grishaeva Yu M , Savosina M I 
Published: November 2019

Abstract
In cities, transport is the leader in the use of the sustainable development – SD concept. The article describes the features of SD of the urban transport in countries with a high level of economic development. In Russia SD of transport is carried out in accordance with national legislation. Urban transport plans should be developed in all regions and municipalities. The analysis shows that the development of transport plans should be preceded by the solution of a number of problems. The main problems are: the inability of administrations of territories and cities to solve new issues of transport planning; lack of methodological developments for designers of transport systems; a fragmentary information base of transport planning; lack of qualified developers of transport plans. The main ways of solving these problems are proposed. Attention is drawn to the need to take into account not only the internal results (they are received by investors and carriers), but also external results obtained by other persons. The formation of civil society institutions is a prerequisite for SD implementation. Training for environmentally and socially oriented professionals should be changed.
Fuel flow and pressure in common return line as a diagnostic parameter of electro-hydraulic injectors technical state
Authors: Yakimov I V , Krivtsov S N , Potapov A S , Svirbutovich O A 
Published: November 2019

Abstract
Electro-hydraulic injectors (EHI) are the most vulnerable components of the common rail injection system of a modern diesel engine. As a rule, the injectors’ diagnostics begins with the analysis of data of the automobile scanner. These data include the current of the high-pressure pumpmetering device, adjustment of fuel pulsewidth when balancing the engine cylinders. A comprehensive analysis carried out by means of a car scanner can be possible only if a pressure sensor is positioned in the control chamber of the injector of the common rail injection system. There are such systems, however the majority of cars, not equipped with them. The scanner data may be influenced by the technical state both of the engine and of the metering device. Consequently, it can be impossible to assess the technical state of the injectors only by means of the car scanner data. It is known that the technical state of the common rail injector is characterized by such indicator as individual fuel back drain.
There is a method of measuring the injectors’ individual leakages by back flow measuring, but it can be applied only if there is an access to individual drain nozzles of EHIs. In many existing common rail injection systems the injectors are located inside the engine, the access to them is hindered. Respectively, only the common return line access is available. High-quality diagnostics of injectors in such systems is possible only with the use of specialized testers, which inevitably leads to increased costs conditioned by disassembling and fitting. To reduce the time of diagnosing electro-hydraulic injectorssignificantly, a method of determining their individual backflow by the common return line was developed.

Published: November 2019

Abstract
The physicochemical characteristics of petrol samples are studied. It is established that the fuel purchased at fuel stations corresponds to the standard parameters presented in the EURO standard for unleaded petrol. The presence of saturated hydrocarbons in petrol is determined using concentrated sulfuric acid, which reacts with unsaturated (alkenes, olefins) and aromatic hydrocarbons, without reacting with saturated hydrocarbons. The fractional composition of petrol samples is determined from the distillation temperatures measured by a mercury thermometer included in the automatic oil distillation apparatus ARNS-1E, acidity titration with an alcohol solution of potassium hydroxide gasoline mixtures with 80% ethanol. An acid-base phenolphthalein indicator (pH = 8.0-9.6) is used to indicate an excess of OH−. The density of the fuel samples is measured with oleometers (densimeters), octane numbers (ON) - indicator (Octanometer) OKTAN-IM. The limit of the permissible absolute error of the measurement of ON is ± 2 octane units. It is established that all petrols without exception contain saturated, unsaturated and aromatic hydrocarbons. It is shown that of the seven samples studied, two samples have some peculiarities. It is concluded that when controlling the quality of fuel, it is necessary to take into account not only the conformity of the determined value to the parameter of the norm, but also the differences in the values of the indices obtained when testing a series of fuel samples.

Published: November 2019

Abstract
Mechanical, electrical, hydraulic and pneumatic transmissions are used in transmissions of agricultural transport technology machines. Depending on the design tasks, the considered transmissions have different kinematic schemes, parameters and design solutions. At the same time, the number of possible options can be quite large; therefore, the determination of the preferred option is, as a rule, a multi-criteria task and often leads to a palliative or compromise choice. The main problem of their development is the adaptability of the design of the actuator to the requirements of the technological (working) process associated with the constant change in the state of the technological object. This paper presents the rationale for developing a theory of kinematic chains of positive orders (adaptive kinematic chains), creating a theory of the structure of adaptive kinematic and adaptive mechanisms in general, methods for static and dynamic analysis of adaptive mechanisms, as well as methods for calculating their basic parameters.
