| Abstract: | In this paper, a study of transient performance about intake charge in engines is presented through multi net method. The gas flow in the intake pipe is calculated using multi net method and characteristic line theory. The transient process of gas flow in the intake pipe in multi cylinder engines is described objectively. Volumetric efficiency affected by the intake system length, diameter and speed is discussed. |
