Abstract

Exhaust manifold serves as breathing equipment for internal combustion (IC) engine removing
combustion products. Backpressure or pressure drop in exhaust manifold is one of the flow
characteristic that gives various effect to IC engine. Current methods of estimating the
backpressure are through computational fluid dynamic (CFD) analysis and experimental analysis.
The effects of backpressure on spark ignition (SI) and compression ignition (CI) engine are usually
severe which includes pumping loss, reduced thermal efficiency, increased brake specific fuel
consumption (bsfc) and reduced brake power. This paper reviews the Various design parameters
that cause backpressure in exhaust manifold such as diameter, shape, length and pipe bend.
