轻42—160柴油机系多缸星形高速强载发动机。其滑油消耗量非常惊人,最高达30克/马力小时以上,一般为10～15克/马力小时。因此,如何降低滑油耗量就成为提高该柴油机质量的一个重要问题。一、滑油耗量大的主要原因经反复观察证实该柴油机具有下列特征; (1)活塞顶及第一道气环上部的活塞顶边缘有大量积炭,有的活塞顶积炭层厚达1毫米左右: (2)排气管內有严重积炭和胶质,甚至还
Light 42-160 diesel engine multi-cylinder star high-speed high-load engine. Its oil consumption is staggering, up to 30 grams per horsepower hour, typically 10 to 15 grams per horsepower hour. Therefore, how to reduce the oil consumption has become an important issue to improve the quality of the diesel engine. First, the main reason for the large fuel consumption After repeated observation confirmed that the diesel engine has the following characteristics; (1) the top of the piston ring and the first ring top of the piston top edge of a large number of carbon deposition, and some piston top carbon layer thickness of 1 Mm or so: (2) Exhaust pipe has a serious coke and colloidal, and even still
