摘要:汽車(chē)發(fā)動(dòng)機(jī)是汽車(chē)的心臟,包括兩大機(jī)構(gòu)、五大系統(tǒng),是一種能夠把一種形式的能轉(zhuǎn)化為另一種更有用的能的機(jī)器。發(fā)動(dòng)機(jī)最早誕生于英國(guó),所以,發(fā)動(dòng)機(jī)的概念也源于英語(yǔ),它的本意是指那種“產(chǎn)生動(dòng)力的機(jī)械裝置”.隨著科技的進(jìn)步,人們不斷地研制出不同用途多種類(lèi)型的發(fā)動(dòng)機(jī),但是,不管那種發(fā)動(dòng)機(jī),都會(huì)發(fā)生故障,因此對(duì)發(fā)動(dòng)機(jī)發(fā)生的故障進(jìn)行分析與排除是十分必要的。通過(guò)運(yùn)用發(fā)動(dòng)機(jī)故障檢測(cè)設(shè)備及經(jīng)驗(yàn)對(duì)汽車(chē)汽油發(fā)動(dòng)機(jī)的常見(jiàn)故障(發(fā)動(dòng)機(jī)不能起動(dòng)或起動(dòng)困難、發(fā)動(dòng)機(jī)功率下降、發(fā)動(dòng)機(jī)溫度過(guò)高、發(fā)動(dòng)機(jī)排煙不正常、發(fā)動(dòng)機(jī)怠速不穩(wěn))進(jìn)行檢測(cè),然后進(jìn)行分析、排除,最終解決故障。

Abstract:Engine is the heart of the car ,including the two bodies ,five systems ,which turn a form of energy into another form of energy machine. The engine was first born in the UK, so the concept of the engine form the English, it is intended to refer to the kind of “mechanical device to generate power”. As technology advances, people are constantly developed various types of engines for different purposes, but, no matter what the engine will fail, therefore, the analysis engine failures and exclusion is necessary. Engine fault detection through the use of equipment and experience of the common gasoline engine failure(engine not staring or staring problems, engine power down, the engine temperature is too high, the engine exhaust is not normal, the engine idle speed in stability)were detected ,and analysis ,exclusion, final settlement failure.
