GB 11340-2005Limits and measurement methods for crankcase pollutants From heavy-duty vehicles equipped with P.I engines (English PDF)

Foreword

In order to implement the "Environmental Protection Law of the People's Republic of China"

and the "Law of the People's Republic of China on the Prevention and Control of Air Pollution",

prevent and control the environmental pollution caused by the crankcase pollutants from heavy-

duty vehicles equipped with P. I engines, and improve the ambient air quality, this Standard is

formulated.

This Standard specifies the type approval application, type approval test, production conformity

inspection method and emission limits of the crankcase pollutants from Category-M and

Category-N vehicles equipped with P.I engines and with a maximum total mass of more than

3,500 kg.

This Standard is a revision on the basis of GB 14761.4-93 Emission Standard for Pollutants

from Crankcase of Vehicle Engine and GB 11340-89 Motor Vehicles - Crankcase Emission -

Measurement Methods and Limit, with reference to some technical contents of GB 18352.2-

2001.

The main differences between this Standard and GB 14761.4-93 and GB 11340-89 are as

follows.

1 The scope of application is adjusted. The emission requirements for the crankcase

pollutants from light-duty vehicles have been included in GB 18352.2-2001.Hence, the

requirements for light-duty vehicles in the previous standard are deleted;

2 The contents of type approval and production conformity are added;

3 The measurement method is modified; the revised measurement method refers to the

stipulations of GB 18352.2-2001;

4 Additional test content is added.

Since the date of issuance of this Standard, the following standards are abolished.

1 GB 14761.4-93 Emission Standard for Pollutants from Crankcase of Vehicle Engine.

2 GB 11340-89 Motor Vehicles - Crankcase Emission - Measurement Methods and Limit.

Appendix A and Appendix B are standard appendixes.

This Standard was firstly issued in August 1989 and firstly revised in November 1993.This is

the second revision.

In accordance with relevant laws and regulations, this Standard is enforceable.

This Standard was proposed by the Department of Science and Technology Standards of

Ministry of Environmental Protection.

The main drafting organization of this Standard. Beijing Automotive Research Institute.

This Standard was approved by the Ministry of Ecology and Environment on April 5, 2005.

This Standard shall be implemented since July 1, 2005.

This Standard shall be interpreted by the Ministry of Ecology and Environment.

Limits and Measurement Methods for Crankcase Pollutants

from Heavy-duty Vehicles Equipped with P. I Engines

1 Scope

This document specifies the type approval application, type approval test method, production

conformity inspection method and emission limits of crankcase pollutants from heavy-duty

vehicles equipped with P. I engines.

This document is applicable to heavy-duty vehicles equipped with P. I engines.

The engines to be tested shall include those for which anti-leakage measures have been taken,

but exclude those engines (for example, horizontally opposed engines), in which, even a slight

leakage in the structure will cause abnormal operation.

7 Implementation of Standard

Starting from July 1, 2005, all vehicles that are subject to the crankcase pollution emission type

approval as specified in Chapter 1 must comply with the requirements of this Standard. Before

July 1, 2005, type approval can be carried out in accordance with the corresponding

requirements of this Standard.
