Research on Exhaust Back Pressure Effect on the Performance features of a CI Engine

Automobiles play a key role in our day today life. Today, studying the parameters which affect the performance of diesel engines is important. In spite of the previous studies, still some aspects needs investigations. In previous researches, valve timing and fuel injection effects on engine performance was studied. In this work, the effect of changing the back pressure of the exhaust gases on the performance of the single cylinder four stroke diesel engine was studied experimentally. The study was experimentally made by varying the length of exhaust pipes with lengths of 0.250 m, 0.500 m, 0.750 m, 1 m and 2 m. It was found that with increase in exhaust pipe length, the exhaust back pressure increases as this decreases the combustion efficiency. Varying exhaust pipe length has considerable influence on performance parameters of the engine. The fuel economy and the volumetric efficiency were found to be the best for a minimum exhaust pipe length.
