在我国城乡,尤其大中城市,后置发动机客车日益受宠。但由于汽车发动机设置在客车尾部,通风冷却条件较差,原设计为风冷式的空压机,就很不适应这一情况,常出现排气温度过高(达250℃以上),导致空压机过热,运动部件出现不正常的过早磨损现象。 In China’s urban and rural areas, especially large and medium-sized cities, rear-engine buses are increasingly favored. However, due to the car engine is located in the rear of the bus, ventilation and cooling conditions are poor, the original design for the air-cooled air compressor, it is not suited to this situation, often appear exhaust temperature is too high (up to 250 ℃ above), resulting in empty Press overheating, moving parts appear abnormal premature wear phenomenon.
