柴油对工程机械发动机使用寿命的影响

The Influence of Diesel Oil to Construction Machinery Engine Service Life

随着我国市政公用设施建设的迅速发展,国外一些技术含量较高的工程机械在行业里得到广泛应用,正确认识燃料对发动机使用寿命的影响,做好相关管理,将有效延长发动机的使用寿命。文章介绍了柴油污染的种类,污染杂质对高压柱塞泵和转子式分配泵的磨损影响,以及采取的有效措施,将燃油对发动机使用寿命的影响降低至最低。

With the rapid development of our country municipal utility and facilities construction, some aboard high technology content construction machinery are applied widely in engineering industry. Because fuel has effect on engine＇s service life, well related management can prolong its service life. The thesis introduces species of diesel oil pollution, the abrasion influence of impurity contamination to high pressure plunger pump and rotor distributor pump, adopting effective measures to decrease diesel oil effect to engine＇s service life in the lowest level.
