现代柴油发动机的发展趋势是体积小、功率大,且低排放,目前普遍采用废气涡轮增压技术来提高发动机功率,但在工作强度大且环境恶劣的情况下使用,易使柴油机工作温度不断增高。因此,冷却系统是保证发动机正常工作的一个重要部分。发动机热量的40%通过润滑油带走,60%通过冷却系统 Modern diesel engine development trend is small, high power, and low emissions, the current widespread use of exhaust gas turbocharger technology to improve engine power, but in the work intensity of the environment and the use of harsh conditions, easy to make diesel engine temperature rising . Therefore, the cooling system is to ensure the normal operation of the engine is an important part. 40% of engine heat is removed by the oil and 60% passes through the cooling system
