捷尔任斯基柴油机制造厂的目标是,把6ЧН21/21型柴油机滑油消耗量的经济性进一步提高到25～40%,到1985年滑油消耗率不超过1.8克/千瓦小时。完成上述任务在相当大程度上取决于选择最有前途的保证得到降低滑油消耗量最大效果的研究方向,同样地,为了选择发动机结构——精加工工艺方向,必须了解和确定 6ЧН21/21型柴油机滑油消耗量的各分量。本文将阐述ЧН21/21系列柴油机滑油消耗量各分量的测定方法及其结果。简图中(图1)涡轮增压柴油机的滑油消耗量Q_(уг)的公式为:Q_(уг)=Q_1+Q_2+Q_3+Q_4式中 Q_1——通过气缸活塞组之间间隙进入燃烧室烧掉的滑油数量;
The goal of the Dzerzhinski diesel engine manufacturer is to further increase the economy of 6ЧН 21/21 diesel oil consumption to 25-40% and to not exceed 1.8 g / kWh by 1985. To accomplish these tasks depends to a large extent on the research direction of selecting the most promising guarantee for the maximum effect of reducing oil consumption. Similarly, in order to select the engine structure - finishing process direction, it is necessary to know and determine the type of 6ЧН21 / 21 Diesel engine oil consumption of the various components. This article will explain the ЧН21 / 21 series of diesel oil consumption of the determination of the various components and the results. In the diagram (Figure 1), the formula of Q_ (уг) for the oil consumption of turbocharged diesel engine is as follows: Q_ (уг) = Q_1 + Q_2 + Q_3 + Q_4 Where Q_1-- enter the combustion through the gap between cylinder piston groups Room burn the amount of oil;
