The engine cannot be started, or the engine does not run and the engine runs but does not work

解決：可以通過聽汽車?yán)鹊穆曇艏包c(diǎn)亮大燈的方法來做個(gè)初步判斷。

Solution: you can make a preliminary judgment by listening to the sound of the car horn and lighting the headlights.

現(xiàn)象1：如果喇叭聲音嘶啞而發(fā)動(dòng)機(jī)不運(yùn)轉(zhuǎn)，此時(shí)應(yīng)該檢查蓄電池。

Phenomenon 1: if the horn is hoarse and the engine does not run, check the battery at this time.

當(dāng)普通蓄電池極板露出來或是免維護(hù)蓄電池觀察孔的顏色不是綠色時(shí)，就可以斷定是蓄電池電力不足造成的發(fā)動(dòng)機(jī)無法啟動(dòng)。遇上普通蓄電池電力不足時(shí)，補(bǔ)充蒸餾水，也可用純凈水應(yīng)急。如果是免維護(hù)電池電力不足，只能用跨接的方法請(qǐng)其他車輛上的蓄電池幫忙了。此時(shí)一定要注意隨車攜帶發(fā)動(dòng)機(jī)的電纜線，在借用其他車輛蓄電池電量時(shí)，電池的正極連正極，負(fù)極連負(fù)極。注意被借方車輛發(fā)動(dòng)機(jī)一定要先啟動(dòng)。

When the electrode plate of ordinary battery is exposed or the color of the observation hole of maintenance free battery is not green, it can be concluded that the engine cannot be started due to insufficient battery power. When the power of ordinary storage battery is insufficient, distilled water or purified water can be used for emergency. If the maintenance free battery has insufficient power, you can only use the jumper method to ask the battery on other vehicles for help. At this time, be sure to pay attention to the cable of the engine with the vehicle. When borrowing the battery power of other vehicles, the positive pole of the battery is connected to the positive pole and the negative pole is connected to the negative pole. Note that the engine of the borrowed vehicle must be started first.

現(xiàn)象2：喇叭及點(diǎn)亮大燈都無異常，但汽車會(huì)發(fā)出“哞呀、哞呀”的聲音。如果用鉗子夾住接頭，輕輕向左右轉(zhuǎn)動(dòng)一下，接頭處發(fā)出“咕吱、咕吱”的移動(dòng)聲音，則可進(jìn)一步斷定為接頭接觸不良。此時(shí)可以選擇用砂紙清理接頭圓柱。當(dāng)沒有砂紙時(shí)，可以用鉗子夾住左右輕輕轉(zhuǎn)動(dòng)來清理圓柱。

Phenomenon 2: the horn and headlights are normal, but the car will make a sound of "moo, moo". If the joint is clamped with pliers and turned slightly to the left and right, and the moving sound of "creak, creak" is sent out at the joint, it can be further determined that the joint is in poor contact. At this time, you can choose to clean the joint cylinder with sandpaper. When there is no sandpaper, you can clamp it with pliers and rotate it gently to clean the cylinder.

現(xiàn)象3：喇叭良好，而發(fā)動(dòng)機(jī)不運(yùn)轉(zhuǎn)，可以考慮發(fā)動(dòng)機(jī)是否通電。如果發(fā)動(dòng)機(jī)本身出現(xiàn)故障，如電磁開關(guān)失效等，就必須采用拆下發(fā)動(dòng)機(jī)，更換零部件的措施了。

Phenomenon 3: if the horn is good and the engine is not running, consider whether the engine is powered on. If the engine itself fails, such as electromagnetic switch failure, the measures of removing the engine and replacing parts must be taken.

小技巧：如果發(fā)動(dòng)機(jī)也未卡死，可以考慮利用外力啟動(dòng)的方法，具體操作要點(diǎn)：將排擋桿推到次高擋(如4擋車型，用3擋)，左腳踏離合器踏板，右腳踩在油門踏板，松開制動(dòng)，打開發(fā)動(dòng)機(jī)開關(guān)。

Tips: if the engine is not stuck, you can consider the method of starting with external force. Specific operation points: push the gear lever to the next high gear (such as the fourth gear model, use the third gear), step on the clutch pedal with the left foot, step on the accelerator pedal with the right foot, release the brake and turn on the engine switch.
