润滑系统的工作状况,直接影响发动机工作的可靠性、耐久性与经济性。为了确保发动机的正常运行,必须搞好润滑系统的维护保养工作,充分发挥其润滑效能。 1.确保机油的工作温度机油的粘度是发动机润滑系统工作中最重要的性能指标,它影响零件摩擦表面润滑油膜的厚度与其完整性,以及零件相对运动时摩擦阻力的大小等。但是机油粘度随温度变化的幅度较大,如8号机油(HC—8)
Lubrication system working conditions, a direct impact on the reliability of the engine work, durability and economy. In order to ensure the normal operation of the engine, we must do a good job of lubrication system maintenance work, give full play to its lubricating performance. 1. To ensure the working temperature of oil The viscosity of the oil is the most important performance of the engine lubrication system performance indicators, it affects parts of the friction surface of the lubricating film thickness and its integrity, as well as parts of the relative movement of the friction resistance size. However, the viscosity of oil changes with the temperature range, such as 8 # (HC-8)
