Özet

Intake manifold connects the intake system to the intake valve of the engine and through which air or air-fuel mixture is drawn into the cylinder. Details of the flow in intake manifolds are extremely complex. Recently, most of engine companies are focused on variable intake manifold technology due to their improvement on engine performance. This paper investigates the effects of intake plenum volume variation on engine performance and emissions to constitute a base study for variable intake plenum. Brake and indicated engine performance characteristics, coefficient of variation in indicated mean effective pressure (COVimep) as an indicator for cyclic variability, pulsating flow pressure in the intake manifold runner, and CO, CO2 and HC emissions were taken into consideration to evaluate the effects of different plenum volumes.
