HJ 438-2008 (English Version) PDF

Scope: This standard specifies the durability of the emission control systems of vehicles equipped with compression ignition engines and their compression ignition engines, as well as vehicles equipped with ignition engines using natural gas (NG) or liquefied petroleum gas (LPG) as fuel and their ignition engines. Technical requirements (including measurement methods). This standard applies to compression ignition (including gas fuel ignition) engines installed on M, M, N, N and N categories with a design speed greater than 25km/h and M category motor vehicles with a total mass greater than 3500kg and their vehicle emissions. Type approval of control system durability. If N and M category vehicles equipped with compression ignition (including gas fuel ignition) engines meet the durability technical requirements of GB 18352.3-2005 "Light Vehicle Pollutant Emission Limits and Measurement Methods (China Phase III and IV)", they may not Implement this standard.
