Abstract:

The motive of the experimentation is to improve the combustion of the direct injection diesel engine powered with biodiesel blend. Initial experimentation was made with the diesel in a conventional unmodified diesel engine. By careful literature survey and technical reviews 20% blend of Pongamia biodiesel with 80% of diesel (B20) had been taken as a test fuel. The swirl motion inside combustion chamber is increased by means of providing the swirling grooves over the piston crown with constant depth 2 mm and variable width of 5.5mm, 6.5 mm and 7.5 mm, unless the previous work done by researches the care has been taken to maintain the compression ratio of the engine. Among the various configurations, the swirling grooves of depth 2mm and width 6.5 mm showed the increase in brake thermal efficiency up to 11 % and decreasing trends in hydrocarbon, carbon monoxide, and smoke emissions. Thus the findings of the present work showed the increase in performance and reduction in the emission of the direct injection diesel engine fuelled with Pongamia biodiesel blend.
