| Summary: | 碩士 === 國立雲林科技大學 === 機械工程系碩士班 === 91 === This research uses the KYMCO’s Apex 125 cc single cylinder gasoline engine to study the intake manifold pressure and the ignition pattern on the engine performance. The engine speed, engine load, intake manifold pressure, ignition timing, and the fuel/air ratio are varied and then the cylinder pressure is recorded. The experimental measurements of pressure are compared to the simulation results calculated by the GESP (Gasoline Engine Simulation Program).
The results indicate that the intake flow can affect the engine performance significantly. The pulse flow inside the manifold can increase the engine volumetric efficiency and thus increase the engine cylinder pressure.
