| Abstract: | In this paper,the FAS (Full Approximation Storage) method is used to study the transient behavior of gas exchange in vehicle engines. The transient parameters of gas flow in intake pipe are measured and the numerical calculation is made on gas flow motion in intake pipe by means of multi-mesh method. The trasient process of gas flow in intake pipe of vehicle engines is described intuitively. So the study provides an effective research method for improving the performance of vehicle engines. |
