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.

　　驾驶室有塑料味-电线过热或有短路

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

　　如果车内有塑料制品的味道，很有可能是电路过热造成的。需要注意的是，线材的外包装一般比较细，所以即使线材过热，气味也不会像离合器片烧坏时那么大。然而，电线烧伤通常伴有局部冒烟或局部发热。如果仔细检查，肯定可以找到源头，确定故障位置。

　　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.

　　济南奔驰汽车维修提醒大家一旦发现线材过热，必须立即停机查明原因。虽然烧电线的气味不大，但风险指数很高。一般春夏季线材过热的情况会比较多。如果不及时发现，很容易造成电路完全损坏，发动机被拉出气缸，甚车辆自燃。

　　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.

　　强烈的焦味---离合器片烧坏或刹车未松开

　　Strong smell - burnt clutch disc or brake not released

　　开车时，如果闻到燃烧非金属材料的特殊气味，通常是因为离合器摩擦片被烧坏，要么太薄，要么过热。这种难闻的气味通常与烧焦的气味混合在一起，因为离合器片是由橡胶、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.

　　如果离合器使用正常，换挡或起步没有明显的困难，而且下车时的气味不是来自车头，而是来自车尾，那么就需要检查是否后制动系统过热。一些粗心的车主在拉手刹的同时用力开车，这样会锁住后刹车片，散发出一股烧焦的味道。

　　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---机油逸入气缸室，参与燃烧

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

　　这种气味一般比较少见，但闻一闻就不会出错。由于机油的燃点与汽油不同，机油不能在气缸内完全压缩燃烧。这时会从排气管排出少量油粒，俗称蓝烟。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.

　　，汽油机车冒蓝烟是不正常的现象。通常，油仅在油道中润滑气缸壁和活塞。但是，一旦气缸内壁磨损严重或活塞磨损严重，原本在油道中的机油就有可能逸出到发动机的燃烧室中。

　　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，气门磨损严重的发动机可能会烧机油，部分车辆油管老化漏油，散发出的机油气味甚可能引发火灾。

　　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.
