What is China 6 Emission Standard?
2 Answers
China 6 Emission Standard, also known as the National Sixth Stage Emission Standard for Motor Vehicles, is established to prevent and control motor vehicle pollutant emissions and improve ambient air quality. Below is a partial introduction to the China 6 Standard: 1. In the China 6a emission standard, the carbon monoxide emission limit for gasoline and diesel vehicles is set at 0.5g per kilometer. China 6a generally adopts the lower limits of the China 5 standard, while China 6b represents the true China 6 emission standard with stricter control over nitrogen oxide emissions. 2. The China 6 emission standard is an upgraded version of the current China 5 standard. It imposes more stringent limits on emissions of CO (carbon monoxide), THC (total hydrocarbons), NMHC (non-methane hydrocarbons), NOX (nitrogen oxides), and PM (particulate matter) compared to the China 5 standard. Additionally, it introduces new regulations on PN (particle number) emissions.
China's National VI emission standard is our country's latest vehicle exhaust control regulation, primarily aiming to significantly reduce pollutants emitted by vehicles. Harmful substances like carbon monoxide and nitrogen oxides are now subject to stricter limits. When purchasing my car, I specifically checked for the National VI compliance label and chose a model that meets the standard. Driving it feels smoother with improved throttle response, slightly better fuel efficiency, and noticeably reduced daily noise levels. In the long run, this standard brings substantial environmental benefits – cleaner air, healthier breathing, and minimized pollution impact on elderly and children. Maintenance-wise, it's worth noting that the after-treatment system may require periodic cleaning at a slightly higher cost, but economically it pays off over time through improved fuel efficiency savings. Overall, National VI represents a robust environmental policy mandated by the government for all new vehicles. As drivers, choosing compliant cars isn't just about regulation adherence but also contributing our share to blue skies.
