柴油机燃烧系统各零部件是在高温高压条件下工作的,而许多运动件是在高速往复或旋转运动状态下工作的,因此会产生大量的摩擦热。要保证发动机能正常运行,就必须有良好的冷却条件。本文以小型柴油机的蒸发式冷却系为例,对影响发动机冷却系性能的根本原因和如何保证其正常工作,谈谈笔者拙见。 Diesel engine combustion system components are working under high temperature and pressure conditions, and many moving parts are in high speed reciprocating or rotary motion, and therefore will produce a lot of friction heat. To ensure the normal operation of the engine, you must have good cooling conditions. In this paper, the evaporative cooling system of a small diesel engine is taken as an example. I talk about the root cause of the cooling system of the engine and how to ensure its normal operation.
