Abstract: PERFORMANCE AND EMISSION ANALYSIS OF 
DIRECT INJECTION DIESEL ENGINE FUELLED BY 
BIODIESEL WITH A1203 NANO ADDITIVES 
ABSTRACT 
Now a day's some of counties stopped the production of diesel vehicles the countries are Japan, 
UK, German, India and so., Biodiesel from watermelon seed oil (WSO) had a lot of appeal and 
could be a different alternative to diesel without any mechanical modifications. This will help 
protect the environmental status of crude oil in oil imports, which is expected to increase by 
82% by 2020. The watermelon biodiesel blends were tested in diesel engine without any 
modification blends reveals the better performance and emissions were observed.  
Five set of watermelon biodiesel blend samples are prepared such as B20, B40, B60, B80 and 
B100. Properties of watermelon blends are finding out as per standards and compared to diesel 
fuel. Testing is carried out to analyze the performance and emission characteristics of diesel 
engine fuelled with various blends of Watermelon biodiesel. The observation of testing fuels 
are conducted on kirloskar single cylinder water cooled constant speed direct injection diesel 
engine with eddy current dynamometer. The engine parameter such as injection timing 23° 
bTDC and injection pressure 210 bars were maintained constant throughout the experiment.  
From the test results, it might be observed that among different blends B20 blend showed 
optimum performance and emission results compared with the neat diesel.The research study, 
performance and emission analysis of a single cylinder diesel engine is fuelled blends of B20 
and diesel. The B20 is taken as standard biodiesel blend from the previous research. The 
nanoparticles is added in the proportions of 20 PPM, 40 PPM and 60 PPM are mixed with the 
B20 [20% of Watermelon Seed Oil (WSO) and 80% of Diesel]. After the mixing of additives 
with a ultrasonicator for 30 minutes for each and every sample B20 with 20PPM, 40PPM and 
60 PPM of additives. From the sample fuels, we get the best formed fuel from these samples 
A or sample B or sample C. The B20 with addition gets the better performance for compared 
to B20. The performance are brake thermal efficiency, total fuel consumption and specific 
energy consumption are taken the reading and calculation. The performance and emission 
analysis are carried out for B20 with additives compared to B100 
and diesel. The emission analysis is Hydrocarbon (HC), Carbon monoxide (CO), Carbon 
dioxide (C02), Oxide of Nitrogen (NO) and smoke. From this Investigation, adding the 
addition of Magnesium Oxide (MGO) has improved the performance and emission to reduced 
and compared to Diesel and Bio diesel. The present study focuses on the comparative behavior 
of B20 [1], which is zirconium dioxide (ZrO2) with various nanoparticles. In some cases, 
zirconia is the white crystalline vi oxide of zirconia, so its most natural form with a monoclinic 
crystal structure is batlite ore. Zirconium dioxide (ZrO2) with B20 compound (20% melon seed 
oil biodiesel + 80% diesel). The compounds were mixed with 20 ppm, 40 ppm, B20 with 60 
ppm and B20 with a magnetic motion for 30 min, followed by sonication of the nanoparticles 
for 30 min, respectively. Biodiesel compounds at a B20 ratio in diesel fuel increase efficiency 
and reduce emissions of hydrocarbons, carbon monoxide and smoke due to the emission of 
nitrogen oxides due to better combustion properties. Criticisms conclude that additional 
applications of biodiesel are best for improving combustion efficiency and reducing emissions.  
In recent decades, several studies have focused on Nanoparticles additives to biodiesel fuels 
because these additives have considerable impacts on the performance, combustion and 
emission on biodiesel fuels. In this research we are going to use Aluminum Oxide (A1203) 
with B20, from previous research ofjournal to achieve specific fuel properties and to improve 
the diesel engine performance characteristics and to attain a good engine emission control 
without any engine modification.
