Fluid motion in compression ignition engine is induced during the induction process and later modified during the compression process. The main problem in compression ignition engine is improper combustion which is due to improper mixing of air and fuel due to shorter delay periods. In conventional engines, air motion is linear and there is no rotational flow of air which leads to improper mixing of air and fuel within the shorter delay periods. In order to enchance proper mixing a secondary motion is to be provided to the air so that it properly mixes with fuel for shorter delay periods which increases engine performance and reduce emissions due to complete combustion, in order to provide secondary motion to the air the design of intake manifold is changed which provides rotational movement to the air instead of linear motion which enhances proper mixing of air and fuel leading to the variation of many engine performance parameters along with emissions. In this work, different designs of intake manifolds are considered and the performance parameters and emissions are calculated and compared with conventional engine.
