Performance simulation research of electronic controlled gasoline engine

摘要

To solve the high or low speed air-intake contradictions in the air-intake system of fixed parameters, based on predesigning the air-intake pipe length variable system in electronic controlled gasoline engine, the gas flow in the pipes is computed and simulated according to the simulative calculation method. The Performance of electronically controlled gasoline engine is analysed under the different speed and load. At the end, the dynamic performance influenced by the length parameter vary air-intake pipe, which findings provide a good reference value for the improvement of the engine's dynamic performance.
