发动机的冷却系统和润滑系统作为发动机最重要的组成部分将直接影响发动机的性能.一方面,发动机工作时,与高温燃烧气体接触的零件受热而温度升高,如不加以适当的冷却,会使内燃机过热,充气系数下降,燃烧不正常,机油变质和烧损,零件的摩擦和磨损加剧,加大柴油机的功率消耗,零件工作表面烧损等引起内燃机的动力性、经济性、可靠性和耐久性全面恶化,致使柴油机无法运转.另一方面,发动机工作时,各运动零件均以一定的力作用在另一个零件上,并且发生高速的相对运动,有了相对运动,零件表面必然要产生摩擦,加速磨损.因此,为了减轻磨损,减小摩擦阻力,延长使用寿命,发动机上都必须有润滑系.为此,本文针对新型双缸卧式柴油机冷却系统和润滑系统的设计要求,参考现有柴油机冷却系统和润滑系统结构,对T2100柴油机冷却及润滑系统进行了设计计算与分析.T2100柴油机冷却系冷却水带走的热量占总热量为19845千卡/小时,散热器散热面积6.06 m2；其水泵流量为47.25 ,转速为1950rpm；机油泵选用结构紧凑,体积小,零件数少,工作转速范围大的转子式机油泵,供油量为10.811～21.622 .计算分析结果表明所设计的冷却系统和润滑系统满足设计要求.

The engine cooling system and engine lubrication system as the most important components will directly affect the engine performance. On one hand, engine work, and contact with high temperature combustion gas and heating parts of the temperature rising, If this is not the appropriate cooling, make the internal combustion engine overheating, inflation coefficient decline is not normal combustion, oil degeneration and burning, Parts exacerbate friction and wear, increasing the power consumption of diesel, spare parts work surface burning caused the engine power, economy, reliability and durability deteriorated, causing diesel unable to operate. The other hand, the engine work, the movements are certain parts of the force in another parts, High-velocity and the relative movement, with relative movement, parts bound to the surface friction and speed up wear. Therefore, in order to reduce wear and reduce friction, extend service life, engine must have the lubrication system. To this end, this paper new Horizontal Two-cylinder diesel engine cooling system and lubrication system design requirements. reference to the existing diesel engine cooling system and lubrication system structure, Diesel right T2100 cooling and lubrication system for the design and analysis. T2100 Diesel Engine cooling water carried away by the heat of the total calories 19,845 kcal / hour, Thermal Radiator 6.06 m2 area; its flow of the pump 47.25, the speed of 1950rpm; Pump selection of compact structure, small size, a few parts, the large scope of speed rotor aircraft pumps, fuel supply for the 10.811 - 21.622. Analysis of results showed that the design of the cooling system and lubrication system to meet design requirements
