【正文】 33 。根據(jù)發(fā)動機冷卻可分為空氣冷卻發(fā)動機水冷發(fā)動機，風冷式發(fā)動機是由發(fā)動機風扇和車輛流量驅(qū)動的速度冷卻引擎；水冷發(fā)動機是依靠循環(huán)冷卻水冷卻的發(fā)動機。冷卻過程。冷卻液，不通過散熱器冷卻。冷卻液從發(fā)動機，通過散熱器的散熱，汽車的前端，再泵入發(fā)動機。自那時以來，冷卻液分為兩個周期。冷卻能力調(diào)整冷卻劑恒溫器，溫控風扇冷卻空氣通過散熱器的音量調(diào)節(jié)。有一點不同的是：加熱周期不是由一個溫控器控制調(diào)節(jié)，只要打開暖氣，周期開始時，無論是冷或熱的冷卻液。冷卻液從發(fā)動機，通過散熱器的散熱，汽車的前端，再泵入發(fā) 動機。汽車冷車，在逐漸變暖的發(fā)動機，冷卻液的溫度 31 不能打開冷卻液恒溫系統(tǒng)，此時就在發(fā)動機中的 “ 冷 ”的循環(huán)泵，目的是使發(fā)動機正常工作溫度盡可能快地。 watercooled engine is to rely on circulating cooling water to cool the engine in the engine. No matter adopt what ways of cooling, the cooling system must ensure that the engine in the range of normal running environment is not overheating. 譯 文 冷卻系統(tǒng)的作用是使發(fā)動機在任何條件下得到適度的冷卻，從而保持適宜的溫度（冷卻液溫度）的工作。 when the coolant temperature is higher than 85 ℃ , part of the cooling liquid cycle。 26 外文資料 Cooling system function is to make the engine get moderate cooling in any condition, so as to maintain the proper temperature (the temperature of the coolant) work. 27 The cooling system cycle includes the main circulating inside the heating cycle The main loop prises two work cycle, namely cold circulation and normal cycle. Cold car with car, the engine in the gradually warming, the temperature of the cooling liquid can not open the thermostat system, cooling liquid at this time just after the pump to cold circulation in the engine, the purpose is to make the engine to normal operating temperature as quickly as possible. With the engine temperature, coolant temperature up to the starting temperature of thermostat (usually the temperature at 80 ℃ ), cooling cycle begins normal cycle. The coolant then from the engine, through the radiator heat dissipation, the front end of the car, then pump into the engine. The car heating circulating cooling fluid through the heating device inside the vehicle, the coolant 28 heat into the car, and then returned to the engine. One point is different: the heating cycle is not controlled by a thermostat, as long as the open heating, the cycle begins, no matter the coolant is cold, or hot. Cooling intensity can be regulated by a thermostat and a temperature control fan. The cooling ability to adjust coolant thermostat, temperature controlled fan cooling air through the radiator volume adjustment. The coolant pump axial entered directly into the water jacket of the cylinder block, the radial impeller, and then flows into the cylinder head jacket. Since then, the cooling liquid is divided into two cycle. A large circulation: coolant flowing through the radiator cooling, the t
