宝马尾气超标的原因

来源:http://www.sdjnltqf.com发布时间:2017-09-21 17:01:01

宝马尾气超标给车主们带来了不少烦恼,尾气超标年检时不通过,那么宝马尾气超标的原因又是哪些呢?
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?
宝马尾气超标的主要原因: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
宝马三元催化器或失效,尾气排放不标准,年检肯定不能通过。


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、道路堵塞不通畅,3、润滑油使用琉磷抗氧剂;
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:三元催化器失效分为可逆性失效和不可逆性失效,可逆性失效是因为三元催化器超期使用,催化剂高温失活造成的,不可逆性失效是因为三元催化器烧结破损造成的。
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.
宝马尾气超标解决处理:
BMW exhaust standard treatment:
1、如果是三元催化器中毒,去汽配市场买一瓶三元清洗剂,对发动机做一次三元清洗保养,保养后尾气年检就可以达标。
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,需要进一步判断是可逆性失效还是不可逆性失效,方法是去汽配市场买一瓶三元养护剂对发动机做一次三元养护,养护过程中散发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.
