发动机作为汽车的主要部件,其性能直接决定了汽车质量的好坏.长期研究发现,发动机只利用了热能的1/3,其余2/3热量都随着冷却空气散入大气,剩余的则被发动机零部件吸收.设备的运行工况及服务年限直接取决于冷却系统设计的合理性.因此,为保证发动机正常工作,必须对这些在高温条件下工作的机件加以冷却.
髮動機作為汽車的主要部件,其性能直接決定瞭汽車質量的好壞.長期研究髮現,髮動機隻利用瞭熱能的1/3,其餘2/3熱量都隨著冷卻空氣散入大氣,剩餘的則被髮動機零部件吸收.設備的運行工況及服務年限直接取決于冷卻繫統設計的閤理性.因此,為保證髮動機正常工作,必鬚對這些在高溫條件下工作的機件加以冷卻.

The engine as the main component of the car, its performance directly determines the quality of the car. Long-term study found that the engine only used one-thirds of heat, and the remaining two-thirds of the heat was scattered into the atmosphere along with the cooling air, the remaining were absorbed by engine parts. Operating conditions and the service life of the device depends directly on the reasonableness of the cooling system design. Therefore, to ensure the normal operation of the engine, these parts working under high temperature conditions must be cooled.
