Simulation on engine characteristic improvement by re-designing intake manifold

In this paper, a simulation of DI diesel engine 1 cylinder, model RV165-2 is used to investigate the effect of intake manifold design on the volumetric efficiency and characteristics by using AVL BOOST software. The proposed plans are evaluated and compared with available models. Conditions of simulation is based on the structure of engine and parameters from experimental test. The parameters of performance, combustion and emission characteristics are selected as evaluation criteria. The results of optimizing intake manifold are increasing volumetric efficiency, ability to blend the mixture of fuel and air, better combustion and increasing engine power, reducing fuel consumption and emission.
