Experimental Analysis of Backpressure Phenomenon Consideration for C.I. Engine Performance Improvement 2010-01-1575

This paper concentrates on backpressure phenomenon, which is a subject of specific interest for design and operation of energy efficient exhaust system development in case of C.I. engine applications. To minimize the problem of back pressure rise, quick and economically feasible solutions are briefly discussed here. Considering the complete system objectives for efficient C.I. engine system development requires minimum fuel consumption and maximum utilization of input energy for reduction of the exhaust emissions and also for effective waste energy recovery system from each subsystem. Specifically particulate matter emission control requires diesel particulate filter, this is a major cause of rise in backpressure. So in the present work, at first critical study of exhaust subsystem design aspects with alternatives available is done, then experimental study of the effect of back pressure generated on the C.I. engine, with and without the use of a specially designed diesel particulate filter is done. Problem of backpressure rise even by small amount is severe and must not be allowed during operating lifespan of any engine system.
