Design and Analysis of X Shaped Exhaust System Operation Using Different Types of Profiles on High Capacity Vehicle

Abstract

The exhaust system used in a 4-stroke IC engine is mounted on the cylinder head of an engine. The gases exhausted from the engine recollected by the exhaust system and it is sent to a catalyst converter. The exhaust manifold has an important role in the performance of an engine system. The exhaust manifold affects the efficiencies of emission and fuel consumption. During the process of collecting the gas from engine and exhaust to catalyst converter, the exhaust manifold experiences temperatures of 800°c and the pressures varying from 100 to 500kpa. Here in this thesis we are going to choose a 4 cylinder 1500cc diesel engine of a car. In this paper, design of the original model and the modified models of X shaped systems using Catia software and then analysed using CFD software for the flow rates and the temperature distribution of the exhaust models. Finally better modification can be determined.
