烧瓦是发动机较为严重的事故。要避免烧瓦的发生,首先需弄清烧瓦的原因,在此基础上才能采取预防烧瓦的措施。 1.由于油底壳中的机油太少、润滑油牌号不对或冬季启动温度太低、机油粘度过大等原因,使机油泵泵油少,造成润滑不良而烧瓦。 2.机油泵不泵油或泵油不足。机油泵内外转子的径向间隙、内外转子和泵壳间的端面间隙等 Burning tile is a more serious engine accident. To avoid the occurrence of burning tiles, we must first understand the reasons for burning tiles, on the basis of this can be taken to prevent the burning of tile measures. 1. Due to too little oil in the oil pan, lubricating oil grades wrong or winter start temperature is too low, the oil viscosity is too large and other reasons, the pump less oil, resulting in poor lubrication and burning. 2. The oil pump does not pump oil or pump oil is insufficient. The radial clearance of the oil pump inside and outside the rotor, the clearance between the inner and outer rotor and the pump casing
