1.前言随着燃油比重的增大,燃油的粘度也随着增高,着火性变差,并在燃油中出现了高硬度的催化粒子。在这种情况下,燃油处理方法的改进、燃油起动性能和着火性的改善,以及磨耗的降低就成了近几年来的重要科研课题。其中关于磨耗问题的研究,由于对磨耗进行评价需要花费大量时间,而且试验数据有很大的离散性,再现性也很差,所以尽管该问题是重要的科研课题,但却很难开展研究。然而,由于船用燃油的特性即使在将来也肯定不会得到改善,因此关于磨耗问题的研究是不能回避的。本文对最易受燃油特性影响的气缸套和活塞环的磨耗评价方法作一介绍,其中包括以往采用 1. Introduction With the increase of the proportion of fuel, the viscosity of the fuel also increases, the ignition of the deterioration, and in the fuel there is a high hardness catalytic particles. Under such circumstances, improvements in fuel handling methods, improvements in fuel starting performance and ignitability, and reduction in wear and tear have become important scientific research topics in recent years. Among them, the research on the wear problem is very difficult to study because it takes a lot of time to evaluate the wear, and the test data is very discrete and the reproducibility is very poor. However, since the nature of marine fuels will certainly not improve in the future, research on the problem of wear can not be evaded. This article presents an overview of the wear assessment methods for cylinder liners and piston rings that are most susceptible to fuel characteristics, including previous
