Development of Port Stationary Test System and Analysis of Numerical Disposing of Evaluation Method

The intake port steady flow test can simulate the actual situation of air intake and evaluate both the flow characteristics of engine air intake system and the capability of forming the swirl, which provide essential testing evidence for the research on developing engine air intake system as well as the combustion process. The steady flow test system developed in this paper applies a structure to realize distributed control by means of construction combining asuperior computer and a subordinate computer, which possesses the features of high automation level, safe and reliable performance and convenience for maintenance and extension. It realizes the intelligentized design of evaluation and control software and obviously increases the calculating accuracy by applying the specific data processing method.
