发动机工作温度对摩托车的性能影响很大。但发动机不同的部位温度不同,很难以一个温度来衡量。对于四冲程摩托车来说,因润滑油同时具有润滑、散热作用,所以润滑油温度的高低间接地反映了发动机温度的高低。摩托车润滑油的温度在343K～363K(70°C～90°C)的正常范围内,才能保证发动机有较大的功率和较好的经济性,这时运动零件的摩擦较小。如果发动机过热,会造成发动机功率下降,经济性变差,各部
The working temperature of the engine has a great influence on the performance of the motorcycle. However, different parts of the engine temperature is different, it is difficult to measure a temperature. For four-stroke motorcycles, because of lubricating oil at the same time with lubrication, cooling effect, so the level of lubricant temperature indirectly reflects the level of the engine temperature. Motorcycle lubricating oil temperature 343K ~ 363K (70 ° C ~ 90 ° C) within the normal range, to ensure that the engine has greater power and better economy, then the friction of moving parts smaller. If the engine overheats, will result in decreased engine power, poor economy, ministries
