In this study, a computer program has been developed which predicts the engine performance characteristics by the analysis of the flow in the intake and exhaust manifold and the cylinder combustion calculation for the MPI spark ignition engines. For the flow calculation, the methods of characteristics has been used and for the calculation in the cylinder, the various combustion models have been used.<br/> Using this program, a study for the optimal design of intake system has been carried out by varing the plenum chamber volume and the both lengths of the pipe which compose the pipe from surge tank to plenum chamber and that from plenum chamber to cylinder.<br/> The experimental work has been pursued to get the pressure variations in both manifold and cylinder and volumetric efficiency. The result of simulation have been compared with that of experimential work and the optimal design data for the experimental engine could be found.<br/>

In this study, a computer program has been developed which predicts the pressure variations and cylinder properties including charging efficiency by the analysis of the flow in each part of a multi -cylinder spark ignition engine. For the flow calculation in the intake and exhaust manifold, the method of characteristics has been used, and for the property calculation in the cylinder, the various combustion models have been used. The<br/> experimential work has been carried out and the results of simulation have been compared with that of experiments.<br/>
