Abstract
- In this work, the design analysis of older and modified exhaust pipe of a four stroke diesel engine are presented and compared. The exhaust gases produced inside a combustion chamber of the engine should be discharge quickly to the atmosphere through exhaust pipe. The flow of exhaust gases mainly depends on back pressure and velocity. During this process, there is a possibility of increase in back pressure due to pipe bends and elbows which hinders the power output of the engine. The measurable outcomes from this research work is to reduce the back pressure to a fair amount which helps in overcoming the power losses. This ultimately will helps in saving the fuel consumption's. The study aims to modify the design of exhaust pipe by reducing the number of exhaust pipe bends. Computational fluid dynamic (CFD) investigation is carried out by modeling the actual geometry of the exhaust pipe. The reduction in the number of bends is correlated with back pressure and frictional losses. The modified design of the exhaust pipe is found to be effective in reducing the pressure drop to around 11.6%. [ABSTRACT FROM AUTHOR]
