1 Answers
The numerical values for the China IV emission standards are: hydrocarbon emissions must be below 0.1 grams per kilometer, carbon monoxide emissions must be below 1.0 grams per kilometer, nitrogen oxide emissions must be below 0.08 grams per kilometer, and there are no requirements for particulate matter. Vehicle emission standards refer to the regulations on the content of harmful gases such as carbon monoxide, hydrocarbons, nitrogen oxides, and particulates emitted from vehicle exhaust. China's emission standards are divided into: China I, China II, China III, China IV, China V, and China VI. The sources of vehicle pollutant emissions come from the exhaust pipe, crankshaft case, and fuel system.
