Design And Coupled Field Analysis Of Exhaust Manifold By Using Different Materials

Abstract

Exhaust manifold receives the exhaust gases comes out from chamber and passes to environment. They usually assembled with cylinder. The exhaust manifold is mounted on the cylinder head of the engine.

Back pressure can be produced at two places, i.e., when the exhaust valve opens and cam overlap taking place. Pressure measurements at the exhaust valve during the start of the exhaust stroke at bottom dead centre (BDC) to cam overlap at the end of the exhaust stroke/beginning of the intake stroke at top dead centre (TDC).The exhaust gases emitted from the cylinder come out at temperatures of nearly 800⁰C and with pressures ranging from 100 to 500 kPa. The exhaust manifold is subjected to high temperatures and pressures which will lead to thermo mechanical failure.
