What is the China 5 Diesel Emission Standard?

[MadelineAnn]

China 5 Diesel Emission Standard is introduced as follows: 1. The China 5 diesel standard is equivalent to the Euro 5 standard in the European Union. The use of new standard gasoline and diesel will reduce multiple pollutants and cut PM2.5 emissions. From China 4 to China 5, environmental protection indicators have been further tightened, with sulfur content reduced from 50ppm to 10ppm, and fuel quality further improved. 2. The China 5 standard refers to the fifth-stage emission standard requirements in "Limits and Measurement Methods for Emissions from Light-Duty Vehicles (China 5)" (GB18352.5-2013) and "Limits and Measurement Methods for Exhaust Pollutants from Compression Ignition and Gas Fuel Positive Ignition Engines of Vehicles (China III, IV, V)" (GB17691-2005), which impose restrictions on vehicle emissions such as nitrogen oxides, hydrocarbons, carbon monoxide, and particulate matter.
