宝马排气不合格怎么办?宝马排气过不了怎么办?宝马尾气不合格,每年的年检,很多车主遇到这样的问题都很着急。过量排放是由于燃料燃烧不足造成的,包括以下原因:
How to deal with BMW's unqualified exhaust? How to deal with BMW's unqualified exhaust? Many car owners are worried about this problem in the annual inspection. Excessive emissions are caused by insufficient fuel combustion, including the following reasons:
1. 三元催化器失效
1. Three way catalyst failure
三元催化器并不是无电流的,由于长期未清洗,积炭严重导致三元排气阻力增大,废气排放恶化超标。
The three-way catalytic converter is not without current. Due to the long-term failure to clean, the carbon deposit seriously increases the three-way exhaust resistance, and the exhaust gas emission deteriorates beyond the standard.
2. 火花塞故障
2. Spark plug failure
火花塞积炭严重,造成汽油燃烧不够,同样会造成废气超标。火花塞需要定期更换,车辆维修时一般包括更换火花塞。火花塞缝隙会引起过量的一氧化碳,积炭会引起过量的烃类价值,更换火花塞是可以解决的。
Serious carbon deposit in spark plug causes insufficient combustion of gasoline, which also causes excessive exhaust gas. The spark plug needs to be replaced regularly. The vehicle maintenance generally includes replacing the spark plug. Spark plug gap will cause excessive carbon monoxide, carbon deposit will cause excessive hydrocarbon value, replacement of spark plug can be solved.

3.机油
3. oil
一般情况下会有烧油现象的车辆,会有不同程度的排烟“大烟”症状,油耗明显增加,在短时间内不得不加油。汽车发动机油的燃烧会导致燃烧室中碳的积累增加,汽车的经济性降低,动力性能下降,尾气排放超标,并不能通过环评等不良后果。
In general, vehicles that burn oil will have smoke "smoke" symptoms in varying degrees, and fuel consumption will increase significantly, so they have to refuel in a short period of time. The combustion of automobile engine oil will lead to the increase of carbon accumulation in combustion chamber, the decrease of automobile economy, the decrease of power performance, and the over standard exhaust emission, which can not pass the environmental impact assessment and other adverse consequences.
4. 氧传感器积碳脏
4. Carbon deposit of oxygen sensor is dirty
一旦车辆燃烧石油污染氧传感器,将导致信号不稳定或错误,建议尽快修复机油故障,否则一个新的传感器坏了几天,最严重的一次是排气管蓝烟,怠速不稳定等问题。
Once the vehicle burns oil to pollute the oxygen sensor, the signal will be unstable or wrong. It is recommended to repair the oil fault as soon as possible. Otherwise, a new sensor has been broken for several days. The most serious problems are blue smoke in the exhaust pipe, unstable idle speed, etc.
