摘要

Different profile structures were designed for a high-power engine piston, and engine tests were carried out to analyze and compare the influences of the widest point position and contraction rate on the skirt wear property. The results show that the lower position of the widest point will cause poor guidance, and at the same time the rapid radial reduction in both the upper and lower parts will increase the swing angles and the kinetic energy; the uniformity of wear loads can be improved effectively by increasing the height of the widest point and the width of the maximum diameter region; the degree of wear of the skirt can be considered through a comparison of the outer diameter variation.
