汽車發(fā)動(dòng)機(jī)冷卻系統(tǒng)中，有一個(gè)部件存在關(guān)系到發(fā)動(dòng)機(jī)是否正常工作，它就是汽車節(jié)溫器。汽車節(jié)溫器根據(jù)冷卻水溫度的高低自動(dòng)調(diào)節(jié)進(jìn)入散熱器的水量，改變水的循環(huán)范圍，以調(diào)節(jié)冷卻系統(tǒng)的散熱能力，保證發(fā)動(dòng)機(jī)在合適的范圍內(nèi)工作。那么汽車節(jié)溫器壞了有什么癥狀呢？節(jié)溫器壞了發(fā)動(dòng)機(jī)水溫會(huì)變得很高嗎？ </p> <p> 首先，導(dǎo)致發(fā)動(dòng)機(jī)水溫過高的因素有很多，其中就包括了汽車節(jié)溫器故障，也是說節(jié)溫器壞了有可能導(dǎo)致發(fā)動(dòng)機(jī)水溫異常升高或者降低。 </p> <p> 如果汽車節(jié)溫器壞了，那么明顯的癥狀會(huì)表現(xiàn)在水溫表上，節(jié)溫器主閥門開啟過遲或過早，如果開啟過遲就會(huì)引發(fā)發(fā)動(dòng)機(jī)過熱；如果開啟過早，就會(huì)使發(fā)動(dòng)機(jī)預(yù)熱時(shí)間延長(zhǎng)，發(fā)動(dòng)機(jī)的溫度過低，從而影響效能。簡(jiǎn)單來說，如果從水溫表看到發(fā)動(dòng)機(jī)水溫過高或者過低，那么有可能還是節(jié)溫器故障了。浙江玉柴瓦錫蘭柴油機(jī)閥芯經(jīng)驗(yàn)豐富通用電氣機(jī)車GE
