On September 16, the reporter learned from the relevant meeting in Nanchang that due to the low elimination rate of motor vehicles, the emission of nitrogen oxides from motor vehicles in the first half of this year did not decrease, and did not catch up with the time schedule formulated at the beginning of the year.
Overall, the environmental air quality in Nanchang has improved significantly this year. From January to July, the air quality standard in Nanchang was 170 days, and the compliance rate was 80.2%, which was 22.2% higher than that of the same period of last year. The concentration of sulfur dioxide, nitrogen dioxide, inhalable particulate matter and fine particulate matter in the atmosphere decreased by 37.5% and 21.4% respectively. 23.5%, 27.9%.
It is understood that due to insufficient elimination of motor vehicles, the situation of nitrogen oxide emission reduction in Nanchang City is severe. In the first half of this year, Nanchang City added 51,900 new vehicles, an increase of 15.6% over the same period last year. Due to the rapid growth of vehicles, the total amount of nitrogen oxides emitted by motor vehicles in Nanchang did not decrease in the first half of the year, and the net increase of nitrogen oxides in the first half of the year was 539 tons.
The relevant person in charge of Nanchang City said that in the second half of the year, Nanchang will strictly enforce the standards for motor vehicle access, increase the frequency of law enforcement inspections in restricted areas, and force the elimination of high-emission vehicles.
A piston ring is a metallic split ring that is attached to the outer diameter of a piston in an internal combustion engine or steam engine. The main functions of piston rings in engines are: Sealing the combustion chamber so that there is minimal loss of gases to the crank case.
Piston rings maintain gas compression between the piston and the cylinder wall. Piston rings seal the cylinder so that combustion gas generated at the time of ignition does not leak into the opening between the piston and the cylinder.
