多缸发动机进气瞬态过程的计算机仿真

Computer Emulation of Transient Process about Intake Charge in Multi-Cylinder Engine

通过实测的多缸发动机进气管总管某一截面上气流参数来计算多缸机进气管各歧管内气流瞬态参数，并实现了对进气管内气体流动的动态仿真，直观地描述了多缸发动机进气管内气体流动的瞬态过程，为换气过程的研究提供了有效的方法。

In this paper, transient paramters of gas flow in intake pipe of multi -cyinder engine are calculated with intake charge paramters in a section of the intake manifold. The dynamic emulation of gas flow in intak pipe is realized, which describes obechvely the transient pmeess of gas flow in inede pipe for multi - cylinder engines. It is considered to be an efficient method for the change process researeh of IC engine.
