引言本文所述的评定气缸套及活塞环磨耗的方法,是为了确定机车柴油机采用加拿大原油的可能性,尤其是为了比较镀铬气缸套与标准铸铁气缸套在各种条件下用原油工作时的磨耗所进行的研究工作一部分。气缸套及活塞环磨耗的直接测量要花费很多的时间,也很费力。为了得到足够 INTRODUCTION The method of assessing cylinder liner and piston ring wear described in this article is to determine the likelihood that a locomotive diesel engine will use Canadian crude oil, especially to compare the wear of a chrome-plated cylinder liner with a standard cast iron cylinder liner over crude oil during various conditions Part of the research carried out. Direct measurement of cylinder liner and piston ring wear takes a long time and is laborious. In order to get enough
