Research on the Structure Optimization Design of Automobile Intake Pipe

As the front end of intake system, dirty pipe is responsible for delivering sufficient and stable air to filter. Therefore, in order meet requirements low resistance, it necessary correspondingly improve flow resistance performance pipe. In this study, main research object was system gasoline engine vehicles, internal gas field simulated analyzed. The results show that there are clear discrete velocity regions at inlet elbow, which affect uniformity overall fluid cause a certain pressure loss. After structural optimization, total difference outlet pipeline reduced by 22.67% compared original model, loss significantly reduced. A simplified model used make samples pipes before after improvement, tests were conducted respectively. between test data simulation within reasonable range, relatively reliable.
