HJ 439-2008: In-service conformity of compression ignition and gas fuelled positive ignition engines of vehicles

The standard specifies the in-service vehicle / engine conformity requirements of automobile equipped with compression ignition engine and its compression ignition engine, the spark ignition engine automobile and its spark ignition engine with NG or LPG as fuel. This standard applies to the in-service vehicle / engine conformity inspection of M2, M3, N1, N2 and N3 classes of vehicles whose designing speed are larger than 25km/h; and M1 class vehicle equipped with compression ignition engines (including gas fuelled positive ignition type) and its automobile whose total mass is larger than 3500kg. If the N1 and M2 classes of vehicles equipped with compression ignition engines (including gas fuelled positive ignition type) engine have been conducted the conformity inspection of in-service vehicle according to the standards of GB 18352.3-2005 Limits and Measurement Methods for Light Car Pollutant Emission (China III, IV stage), it does not have to perform this standard.

Foreword
According to Environmental Protection Law of the People's Republic of China and The People's Republic of China on The Prevention and Control of Air Pollution, and in order to prevent the pollutions of automobile emissions of automotive compression ignition and gas fuelled positive ignition engines TO the environment, improve the environment quality, this standard is formulated.
This standard specifies in-service vehicle conformity requirements of automobile equipped with compression ignition engine and its compression ignition engine, the spark ignition engine automobile, and its spark ignition engine with NG or LPG as fuel. This standard is the supplement of in-service vehicle / engine conformity contents TO GB 17691-2005 Limits and Measurement Methods for Exhaust Pollutants from Compression Ignition and Gas Fuelled Positive Ignition Engines of Vehicles (China III, IV, V stage). The modification of technical contents in this standard adopts EU order 2005/55/EC the council order in regard to coordinating with all member states to adopt measures to prevent gaseous pollutant and particulate matter emissions laws of automotive compression ignition engine and automotive spark ignition engines of burning natural gas or liquefied petroleum gas, as well as the contents of relevant in-service vehicle / engine conformity in the revision orders 2005/78/EC and 2006/51/EC.
Annex A of this standard is normative.
This standard is first-time issued.
This standard is organized and formulated by Department of Science, Technology and Standards of Ministry of Environmental Protection.
Main drafting organizations of this standard. China Research Academy of Environmental Sciences, JNATC (Jinan Automotive Test Center), and Chinese Automotive Technology and Research Centre.
The standard was approved by Ministry of Environmental Protection on June 24, 2008. This standard shall be implemented from July 1, 2008.
The Ministry of Environmental Protection is responsible for the interpretation of this standard.
In-service conformity of compression ignition and gas
fuelled positive ignition engines of vehicles
1 Application??scope
The standard specifies the in-service vehicle / engine conformity requirements of automobile equipped with compression ignition engine and its compression ignition engine, the spark ignition engine automobile and its spark ignition engine with NG or LPG as fuel.
This standard applies to the in-service vehicle / engine conformity inspection of M2, M3, N1, N2 and N3 classes of vehicles whose designing speed are larger than 25km/h; and M1 class vehicle equipped with compression ignition engines (including gas fuelled positive ignition type) and its automobile whose total mass is larger than 3500kg. If the N1 and M2 classes of vehicles equipped with compression ignition engines (including gas fuelled positive ignition type) engine have been conducted the conformity inspection of in-service vehicle according to the standards of GB 18352.3-2005 Limits and Measurement Methods for Light Car Pollutant Emission (China III, IV stage), it doesn?€?t have to perform this standard.
2 Normative??references
The articles contained in the following documents have become part of this standard when they are quoted herein. For the undated documents so quoted, the latest editions shall be applicable to this standard.
