摘要：

By adopting CFD numerical simulation software, the transient state numerical simulation of engine is carried on. The intake and compression stroke are studied in maximum power and maximum torque conditions. Through numerical simulation, we can learn the change of TKE with the crank angle, and give a guide for improving design of intake port and chamber. At last, a conclusion is found about the engine that at high speed, the gas flow in cylinder infects the stability of spark ignition.
