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.
