Summary:

Exhaust system of an automobile is primarily employed in automobile to purify exhaust gases and reduce noise due to combustion. However, a side-effect of the above function is the increase in backpressure. As specified in various literatures, an increase in backpressure can lead to a deterioration on engine performance (Power and torque). Benefit of backpressure reduction can be further taken in terms improving the power and torque of engine or improving the fuel economy. With growing concerns related to global warming and CO2 emissions, reducing exhaust back pressure is one of the promising areas in engine design in order to improve the fuel economy of the automobile and achieving carbon neutrality targets. However, reducing the back pressure generally tends to deteriorate the noise attenuation performance of the Exhaust system. Hence, it is imperative to reduce backpressure of an Exhaust system while at the same time ensuring adequate noise attenuation, for passenger comfort and noise regulations.This paper analyses impact of various components in exhaust system on backpressure and provide optimal solution for reduction of the same. The backpressure reduction resulted in an improvement in engine efficiency, which was then further harnessed for improving the fuel economy of the engine.Subsequent sections explain the approach for study and the results
