1问题的提出东风4B型机车柴油机冷却系统分为高温和低温循环水系统。高温循环水系统主要用于冷却气缸套、气缸盖、增压器等部件;低温循环水系统主要用于冷却机油、增压空气、静液压油等。柴油机各部件的热量通过冷却循环系统,在冷却间由散热器单节将大部分热量传递给空气,以保?
1 The question put forward Dongfeng 4B locomotive diesel engine cooling system is divided into high temperature and low temperature circulating water system. High temperature circulating water system is mainly used for cooling cylinder liner, cylinder head, supercharger and other components; low temperature circulating water system is mainly used for cooling oil, pressurized air, hydrostatic oil. Diesel engine parts through the cooling cycle of the cooling system in the cooling room by the radiator will be most of the heat transferred to the air in order to protect?
