柴油机的机油消耗,除了不正常的漏油外,主要有两个途径,一是通过呼吸器以油雾或油液的形式排出,二是通过排气道以碳烟、油雾或油液的形式排出。呼吸器呼机油的问题,主要取决于呼吸器的设计和曲轴箱的压力;而排气道呼油则来源于进入气缸的机油,进油的途径一是气门导管,另一个是气缸本身。本文探讨气门与气门导管的匹配、润滑和密封对柴油机窜烧机油的影响。 Diesel engine oil consumption, in addition to abnormal leakage, there are two main ways, one through the respirator in the form of oil mist or oil discharge, the second is through the exhaust duct to soot, oil mist or oil Form discharge. Breathing machine call oil problems, mainly depends on the design of breathing apparatus and crankcase pressure; and exhalation of the oil from the cylinder into the oil, the way to enter the oil valve guide catheter, and the other is the cylinder itself. This article discusses the valve and valve guide matching, lubrication and sealing on the diesel engine oil burning effect.
