| Abstract: | Intake system optimization to increase the volumetric efficiency is an important approach to the improvement of the gasoline power.Establish a cycle simulation model by the simulation software Boost,and investigate the influence of the length and diameter of intake on volumetric efficiency and engine performance,then decide the work process that design the variable geometric intake.It is shown by calculation that the gasoline engine with variable geometric intake system has higher volumetric efficiency.The dynamic performances of the engine are improved. |
