Reasons for exceeding the limit of automobile exhaust emissions detected by exhaust gas detection lines

With the mandatory emission reduction by the country and the gradual implementation of policies to promote environmental protection, various regions have gradually strengthened the inspection and control of motor vehicle exhaust emissions. Motor vehicle exhaust emissions account for 60% of air pollution, and controlling motor vehicle pollution has become a key part of air purification. As a result, most car owners are concerned about whether their exhaust emissions can meet the standards. With increasingly strict environmental inspections, most poorly maintained vehicles cannot pass the annual inspection smoothly.

Reasons for exceeding the limit of automobile exhaust emissions detected by the exhaust gas detection line:

Firstly, the exhaust gas detection line is used to detect the aging of various components in automobiles. This is mainly aimed at older cars, as the aging phenomenon occurs due to the prolonged use of various components. In daily use, car owners can also clearly notice a direct decline in performance, and the exhaust emissions from automobiles also have a certain gap compared to before. Therefore, due to production process issues, as an old car, its production process may have met the standards in the past, but now, due to the progress of production technology and the enhancement of emission standards, it is easy to have excessive exhaust emissions.

Secondly, the fuel quality added to the exhaust gas detection line is poor: Fuel quality also has a certain impact on the emissions of car exhaust, and usually imported cars, especially some high-end cars, require higher fuel quality. Moreover, the fuel quality in China, especially in some remote areas, often cannot meet the corresponding standards. Long term use of poor quality fuel can easily lead to emissions exceeding the standard, which also leads to the failure of vehicle annual audits.

The blockage of the air filter filter in the exhaust gas detection line has a significant impact on the engine. On the one hand, the blockage of the filter will increase engine fuel consumption, thereby reducing engine power. On the other hand, the blockage of the air filter filter will cause excessive exhaust emissions in the car. The air conditioning filter on the car is used to block the entry of air, dust, and debris from outside the car into the air conditioning unit. Therefore, I suggest that you fix it in place or go to a 4S store for replacement. Otherwise, it will not only affect the car engine but also have adverse effects on the owner's body.
