DYNAMIC VALVE SYSTEM WEAR TESTING DEVICE BY ADDING WEIGHT

摘要

PURPOSE:To provide a dynamic valve system wear testing device which can adjust the degree of severeness which is a load element applied to a testing body easily with an improved reproducibility in the dynamic valve system wear test of an engine. CONSTITUTION:A plurality of valve springy retainers with different weights in a dynamic valve system consisting of an engine dynamic valve system 1, a motor 6 for forcibly driving the engine dynamic valve system, and a driving member for transmitting the rotation of a motor to the dynamic valve system are prepared and can be changed freely.
