A REVIEW PAPER ON EFFECT OF INTAKE MANIFOLD GEOMETRY ON PERFORMANCE OF IC ENGINE
Intake manifold its components play crucial role in deciding the performance of an IC engine. Engine breathing can be easily related to the intake geometry as per the different researchers worldwide. Intake manifolds affect the volumetric efficiency which ultimately makes impact up on the engine power torque. Conventional intake manifolds have fixed geometry thus does not cater for the demand of wide range of engine speeds. This paper reviews the work done by various prominent researchers' in the field of intake tuning variable intake manifold. It can be easily concluded that for getting maximum volumetric efficiency throughout the engine operating speed the intake geometry needs to be changed. At lower engine speed intake length must be long for proper breathing of engine while at higher speeds intake length must be short. Considerable gain in torque fuel economy can be observed with variable intake length manifold.
