一、正确使用节温器。目前,国产汽车发动机所使用的节温器有折叠式和蜡式节温器两种。折叠式节温器对冷却系中的工作压力较每感,但工作可靠性差、寿命短、使用中易于损坏,因此,驾驶员必须经常检查。蜡式节温器具有工作稳定,水流阻力小,流入散热器的流量较大,结构牢固,使用寿命长,耐热、耐冻、耐压和反应每感性较差等特点,一般每行驶5万公里应检查一次。 First, the correct use of thermostat. At present, the thermostats used in domestic automobile engines are both folding and wax-type thermostats. Folding thermostat cooling system in the work of each pressure, but poor reliability, short life, easy to damage during use, therefore, the driver must always check. The wax-type thermostat has the characteristics of stable work, small flow resistance, large flow into the radiator, solid structure, long service life, heat-resistance, freezing-thawing, Km should be checked once.
