寶馬尾氣超標給車主們帶來了不少煩惱，尾氣超標年檢時不通過，那么寶馬尾氣超標的原因又是哪些呢？
BMW excessive emissions to owners who have brought a lot of trouble, exhaust gas exceeded the annual inspection does not pass, then BMW exhaust exceeded the standard and what are the reasons?
寶馬尾氣超標的主要原因：三元催化器中毒和失效
The main reason why BMW exhaust gas exceeds standard is three yuan catalyst poisoning and invalidation
寶馬三元催化器或失效，尾氣排放不標準，年檢肯定不能通過。

BMW three yuan catalyst or failure, exhaust emissions is not standard, the annual inspection certainly can not pass.
三元催化器中毒的原因：1、汽油含硫高，2、道路堵塞不通暢，3、潤滑油使用琉磷抗氧劑；
Three yuan catalyst poisoning reasons: 1, high sulfur gasoline, 2, road congestion is not smooth; 3, the use of lubricating oil phosphorus antioxidant;
三元催化器失效的原因：三元催化器失效分為可逆性失效和不可逆性失效，可逆性失效是因為三元催化器超期使用，催化劑高溫失活造成的，不可逆性失效是因為三元催化器燒結破損造成的。
Three catalytic converter failure: failure is divided into reversible and irreversible failure failure three waycatalytic, reversible failure because of the three catalytic converters use extended catalyst deactivation at high temperature due to the irreversibility of the failure is because of three waycatalytic damage caused by sintering.
寶馬尾氣超標解決處理：
BMW exhaust standard treatment:
1、如果是三元催化器中毒，去汽配市場買一瓶三元清洗劑，對發動機做一次三元清洗保養，保養后尾氣年檢就可以達標。
1, if it is three yuan catalyst poisoning, go to the auto parts market, buy a bottle of three yuan cleaning agent, the engine to do a three yuan cleaning, maintenance, after maintenance, exhaust gas inspection can reach the standard.
2、如果是三元催化器失效，需要進一步判斷是可逆性失效還是不可逆性失效，方法是去汽配市場買一瓶三元養護劑對發動機做一次三元養護，養護過程中散發出很臭的二氧化硫味就是可逆性失效，反之就是不可逆性失效。
2, if it is three yuan catalytic converter failure, the need for further judgment is reversible or irreversible failure failure, method to auto market to buy a bottle of three yuan three yuan for a curing agent curing on the engine, exudes a very smelly smell of sulfur dioxide is a reversible failure maintenance process, and is irreversible failure.
