本文介绍了降低ЯМЗ型发动机机油消耗量的途径。同时对机油经进气阀导管间隙而烧损的情况进行了评定。应当指出,因机油烧损而造成的机油消耗量几乎占修理后柴油机机油总消耗量的80%。为了减少机油经进气阀导管间隙渗入气缸里,在大多数汽油机进气阀上装上不同结构的密封罩(密封元件)。某些国外柴油机进气阀也装用密封罩。试验研究表明,装用密封元件 This article describes ways to reduce the amount of ЯМЗ engine oil consumption. At the same time on the oil through the intake valve catheter gap and burn the situation was assessed. It should be noted that the oil consumption due to the burning of oil accounts for almost 80% of the total diesel engine oil consumption after repair. In order to reduce oil penetration into the cylinder through the intake manifold clearance, seals of different configurations (sealing elements) are mounted on most gasoline inlet valves. Some foreign diesel intake valve is also equipped with a sealed cover. Experimental studies have shown that the installation of sealing elements
