Abstract
In this experiment, the engine (i30 FD) was fabricated and installed in front of the intake manifold of the gasoline engine of the 2010 1,600cc MPI(Multi Point Injection) 4-cylinder 16-valve DOHC(Double Over Head Camshaft) electronic control fuel injection system, and the plenum chamber was 150cc, 300cc, 4. The engine rotation speed was increased from 1000rpm to 3000rpm by 500rpm, and the pressure change and engine volume efficiency change of the air intake manifold runner were analyzed. In this study, the volume of air flowing into the cylinder was maximized through the stabilization of pressure vibration in the intake manifold runner part due to the engine operation condition and the volume change of the intake manifold plenum chamber, and the uniform distribution rate of the intake air was confirmed by minimizing the interference between the cylinders. It has in the purpose to analyze the flow characteristic at the intake manifold inside. It can apply to obtain the optimal design factor.
