Can you tell what's wrong by the smell of the car? Don't be surprised, it's a fact! Because normally cars smell almost nothing, but when a part breaks down, they emit a pungent odor. So let's see what happens.

　　駕駛室有塑料味-電線過熱或有短路

　　Plastic smell in cab. - Overheating or short-circuited wiring

　　如果車內(nèi)有塑料制品的味道，很有可能是電路過熱造成的。需要注意的是，線材的外包裝一般比較細(xì)，所以即使線材過熱，氣味也不會像離合器片燒壞時那么大。然而，電線燒傷通常伴有局部冒煙或局部發(fā)熱。如果仔細(xì)檢查，肯定可以找到源頭，確定故障位置。

　　If there is a smell of plastic in the car, it is most likely due to overheating of the circuit. It should be noted that the outer packaging of the wire is generally fine, so even if the wire overheats, the smell will not be as big as when the clutch plate burns out. However, wire burns are usually accompanied by local smoke or local heat. If you check carefully, you can definitely find the source and locate the fault.

　　濟(jì)南奔馳汽車維修提醒大家一旦發(fā)現(xiàn)線材過熱，必須立即停機查明原因。雖然燒電線的氣味不大，但風(fēng)險指數(shù)很高。一般春夏季線材過熱的情況會比較多。如果不及時發(fā)現(xiàn)，很容易造成電路完全損壞，發(fā)動機被拉出氣缸，甚至車輛自燃。

　　Ji 'nan Benz car maintenance to remind you once found wire overheating, must immediately stop to find out the cause. The smell of burning wires is mild, but the risk is high. The case of overheating of wire of general spring and summer can be more. If not found in time, it is easy to cause complete circuit damage, the engine is pulled out of the cylinder, or even the vehicle spontaneous combustion.

　　強烈的焦味---離合器片燒壞或剎車未松開

　　Strong smell - burnt clutch disc or brake not released

　　開車時，如果聞到燃燒非金屬材料的特殊氣味，通常是因為離合器摩擦片被燒壞，要么太薄，要么過熱。這種難聞的氣味通常與燒焦的氣味混合在一起，因為離合器片是由橡膠、石棉等材料制成的。

　　While driving, if there is a distinctive smell of burning non-metallic material, it is usually because the clutch friction plate has been burned, either too thin or overheated. The unpleasant smell is often mixed with the smell of burning because the clutch plates are made of rubber, asbestos and other materials.

　　如果離合器使用正常，換擋或起步?jīng)]有明顯的困難，而且下車時的氣味不是來自車頭，而是來自車尾，那么就需要檢查是否后制動系統(tǒng)過熱。一些粗心的車主在拉手剎的同時用力開車，這樣會鎖住后剎車片，散發(fā)出一股燒焦的味道。

　　If the clutch is working properly, there is no apparent difficulty in shifting gears or starting, and the smell of dismounting comes not from the front but from the rear, then the rear braking system needs to be checked for overheating. Some careless drivers drive too hard with the handbrake on, which locks the rear brake pads and gives off a burning smell.

　　混合汽油的油味---機油逸入氣缸室，參與燃燒

　　The smell is generally rare, but you can't go wrong with a sniff. Because the ignition point of

　　這種氣味一般比較少見，但聞一聞就不會出錯。由于機油的燃點與汽油不同，機油不能在氣缸內(nèi)完全壓縮燃燒。這時會從排氣管排出少量油粒，俗稱藍(lán)煙。The smell of oil mixed with gasoline - the oil escapes into the cylinder chamber and participates in combustionoil is different from that of gasoline, oil cannot be fully compressed in the cylinder. A small amount of oil particles, commonly known as blue smoke, will be discharged from the exhaust pipe.

　　首先，汽油機車冒藍(lán)煙絕對是不正常的現(xiàn)象。通常，油僅在油道中潤滑氣缸壁和活塞。但是，一旦氣缸內(nèi)壁磨損嚴(yán)重或活塞磨損嚴(yán)重，原本在油道中的機油就有可能逸出到發(fā)動機的燃燒室中。

　　First of all, gasoline engine blue smoke is absolutely abnormal phenomenon. In general, oil lubricates the cylinder walls and pistons only in the oil passage. However, once the cylinder wall wear or piston wear is serious, the oil in the oil passage may escape into the combustion chamber of the engine.

　　此外，氣門磨損嚴(yán)重的發(fā)動機可能會燒機油，部分車輛油管老化漏油，散發(fā)出的機油氣味甚至可能引發(fā)火災(zāi)。

　　In addition, the engine with serious valve wear may burn oil, part of the vehicle oil pipe aging oil leakage, oil smell may even cause a fire.
