1.三元催化器故障
1. three catalytic converter fault
三元催化器不通暢，因為很長時間都沒有清洗，積碳嚴重導致三元排氣阻力增大，排放惡化尾氣超標。
Three yuan catalytic converter is not smooth, because it has not been cleaned for a long time, carbon deposition serious lead to three yuan exhaust resistance increased, exhaust emissions exceeded the standard.
2.火花塞故障
2. spark plug fault
火花塞積碳嚴重，導致汽油燃燒不充分，同樣會引起尾氣超標?；鸹ㄈ枰ㄆ诟鼡Q，車輛做大保養一般包含有更換火花塞在內?；鸹ㄈg隙過大會造成一氧化碳超標，積碳過多會造成碳氫值超標，更換火花塞可解決。
Spark plug fouling is serious, resulting in gasoline combustion is not sufficient, it will cause emissions exceed the standard. The spark plug needs to be replaced regularly, and the maintenance of the vehicle usually involves replacing the spark plug. The spark gap will cause carbon monoxide exceed the standard, too much will cause the value of the spark plug can exceed the standard of hydrocarbon, replacement solution.

3.發動機燒機油
3. engine oil burning
一般有燒機油現象的車輛，都會有不同程度的尾氣冒“大煙”的癥狀，機油消耗明顯增加，較短的時間內就不得不補加機油。車輛燒機油，會導致燃燒室的積碳增加、汽車的經濟性、動力性下降、尾氣排放超標，而無法通過環評等等不良后果。
Generally have the phenomenon of burning oil vehicles will have different degrees of exhaust take "Opium" symptoms, oil consumption increased significantly, a relatively short period of time will have to add oil. The burning of engine oil will lead to the increase of carbon deposition in the combustion chamber, the decline of the economy and power of the vehicle, the excessive emission of exhaust gas, and the adverse consequences of environmental assessment and so on.
4.氧傳感器積碳骯臟
4. oxygen sensor carbon deposition dirty
車輛一旦燒機油就會污染氧傳感器，造成信號不穩或者出錯，建議盡快修復發動機燒機油故障，否則換一個新傳感器幾天功夫就壞，更嚴重的時候就是排氣管冒藍煙，怠速不穩等故障出現。
Once the vehicle will burn oil pollution caused by oxygen sensor, signal instability or error, advice as soon as possible to repair the engine burning oil fault, or for a new sensor a few days on the bad, the most serious is the blue smoke, idling instability fault.
