Experimental Study on Diesel Engine Intake Ports with Reverse Engineering Technology

摘要

Compared the principle and application effect of non-contact measuring data collecting method of intake ports: the nondestructive scanning method and laser scanning method. A intake port was developed for a four-valve diesel engine with reverse engineering technology, and different core boxes of intake port were made respectively by different measureing and manufacturing method, and were investigated in the steady-flow test with the original cylinder head of the diesel engine. The results show that the performance of the metal core box based on laser scanning is consistent with the original cylinder head. Compared with the epoxy resin core box based on nondestructive scanning method, the metal core box based on laser scanning can satisfy the requirement of development of intake port.
