The combustion process in the internal combustion engine is varying cycle to cycle while changing load, speed, etc. It is difficult
to achieve better fuel economy and reduce pollution emissions. Literature shows that design of a taper, straight and lower thermal
inertia exhaust manifold gives better mass conservation, fuel economy and engine efficiency. Back pressure on engine having a
strong influence on engine efficiency and need to be minimized by using divergent shape exhaust manifold. Main objective of this
invention is to improve the scavenging process to clean the cylinder from exhaust gases for fill up maximum volume of fresh air to
increase volumetric efficiency and finally increase overall efficiency of an engine.
