What's the difference between country five and country six?

The difference between National Five and National Six of Pacific Auto Network is that the emission standard of National Six has increased by 40% to 50% on the basis of National Five, which is the most stringent emission standard at present, even stricter than Euro Six. Of course, with the implementation of the national six emission standards, the environment will also be greatly improved.

The key difference lies in the different emission standards. National VI needs to be stricter than National V, which is formulated according to the 20 17 air pollution prevention and control work plan of the Ministry of Environmental Protection. Liu Guo? , relative? Guowu? The content of carbon monoxide, PM fine particles and benzene in motor gasoline is strictly 40%! (The maximum sulfur content of national standard gasoline is 50mg/kg, and the maximum sulfur content of national standard gasoline is 10mg/kg. ), numerically, the emission limits of CO (carbon monoxide), THC (total hydrocarbons), NMHC (non-methane hydrocarbons), NOX (nitrogen oxides) and PM (particulate matter) in the National Sixth Standard are stricter than those in the National Fifth Standard by 50%, 50%, 49%, 42% and 33% respectively, and the emission of PN (particulate matter) is stricter.
