The Overrun Blow By Problem Analysis of Diesel Engine and the Solution

发动机漏气量大是困扰发动机行业的难题之一 ,高温、高压燃气如果大量泄露 ,往往会导致活塞异常膨胀变形拉缸、环胶结、卡滞、机油恶化等异常事故。本文利用GLIDE软件 ,针对某柴油机漏气量大的问题 ,进行分析并提出解决措施。

The overrun blow by is one of difficult problems of d ie sel engine. If large quantities of high temperature and pressure gas blows ,it w ill make the piston expend excessively, the piston ring cementation and locked, the lubricating oil worsen etc. , We analysis the problems of the overrun blow b y in the GLIDE software and put forward the solution.
