What are the differences between China 6 and China 5 standards?
1 Answers
Here are the specific differences between China 5 and China 6: 1. China 6 adopts a fuel-neutral principle, meaning the emission limits are the same regardless of the fuel type used. In the China 5 phase, diesel and gasoline vehicles had different emission standards. 2. Compared to China 5, the China 6 standard reduces nitrogen oxides (NOx) by 77%, particulate matter (PM) by 67%, introduces a limit for particle number (PN), and includes requirements for emission control device durability and on-board diagnostics (OBD). 3. China 6 imposes stricter compliance monitoring requirements, including type testing and information disclosure, production conformity checks, new vehicle inspections, in-use compliance checks, and simplifies the compliance determination method.
