Summary: This standard specifies the basic requirements to meet in GB/T 21404-2008 " core" standards established for exhaust emission tests in accordance with GB/T 8190 regulations reciprocating engine power when needed to determine additional requirements and methods. This standard also provides for the determination of the pre- adjustment of the engine under variable atmospheric conditions power correction method. The Amendment Act does not apply to determine the value of the exhaust pollutant emissions, because it is not only about the correction of engine power under all borrowing conditions. This standard applies to land use, rail traction and marine reciprocating internal combustion engines. But does not include the main engines for road vehicles. This standard applies to drivers, such as road construction machinery, industrial trucks and other uses of the engine, earthmoving machinery. This standard is a "satellite " standard, only in conjunction with GB/T 21404-2008 " core" standards in order to fully use the technical requirements specific engine.

Foreword

This standard is ISO engine power measurement standards in the "satellite" standards for engine emissions before the test to determine engine power. This standard is developed in accordance with the relevant provisions from ISO /IEC Directives, Part 3. This standard is identical with ISO 14396.2002 "and methods of measurement to determine the reciprocating internal combustion engine power ISO 8178 exhaust Additional requirements for emission tests "(in English). This standard is equivalent to translate ISO 14396.2002. For ease of use, this standard made the following editorial changes. --- "This International Standard" by "this standard"; --- Remove the foreword to international standards; --- The standard ISO 14396.2002 and other international standards referenced in our country who have been adopted as a standard by our standards on behalf of the For the corresponding international standards have not been adopted as our standard, still refer directly to international standards. The standard proposed by China Machinery Industry Federation. This standard by the National Standardization Technical Committee of the internal combustion engine. This standard was drafted. Shanghai Institute of the internal combustion engine, Weichai Power Co., Ltd., Guangxi Yuchai Machinery Co., Ltd., Beiqi Fu Tian Automobile Co., Ltd., Shanghai Diesel Engine Co., Ltd. Ningbo Xuelong Group. The main drafters of this standard. Xie Yaping, Ge Hong, Wang Hui, Zhang Lili, Qiu Guoping, Yang Jian, Duan Yao Long, meter-dimensional Bin, Wang, Chen Yunqing, Qujun Ming, Song Guochan, Bi Ye. This standard was first formulated. GB/T 21405-2008/ISO 14396.2002

Introduction

This standard establishes the ISO engine power measurement standards in a standard satellite, to avoid the use of the standard in a given engine power Many specious ISO standards and identify areas of shortcomings of justice occurred. This standard uses the "core" - "satellite" principle. GB/T 21404-2008 "core" common standard contains requirements for various engine applications, and this standard as a "satellite" standard It contains specific purpose engine power measurement and calibration as specified in Chapter 1 of the necessary requirements. This standard is only used with the GB/T 21404-2008 "core" standards, in order to fully provide for specific engine applications requirements. Therefore, the file "satellite" is not a standard that can exist alone, but through GB/T 21404-2008 "core" standards required to Seeking to form a complete standard. To ensure ease of use, in the development of "core" standards and "Satellite" standard adopts a very similar structure. The advantage of using this method is that it is reasonable to use the same or similar standards for engines for different purposes, and to ensure that the standard Made in quasi-coherent system, the revision process. Compared with road engines, non-road engines Due to its versatility, it has a wide power range and numerous structures form. GB/T 8190 the aim is to make non-road engine testing procedures of gaseous and particulate emissions of rationalization in order to simplify the hand Continued, more cost-effective to draft regulations for the engine specifications and to carry out the engine certification. For this purpose a concept and uses. The power of the engine when equipped with only basic secondary slave device issued to Ratio calculation engine emissions (g/kW · h). GB/T 8190 has been used in legislation, regulations and regulatory agencies have different limits depending on the engine power. The standard gauge Given the need for determining the engine power when in accordance with GB/T 8190 requirements for test procedures. According to GB/T 8190 shall be calculated emission ratio, power measurement is not corrected based on the value, because the engine emissions with the environmental Availability varies, but not being able to correct for this measurement. Accordingly, the scope of this standard will allow the provisions of the environmental situation is very small, in order to It will minimize its impact. Power correction program of the present standard to meet environmental test conditions and wide use, can be used to carry out before the engine emission testing to determine hair Motive power.

1 Scope

This standard specifies the basic requirements to meet in GB/T 21404-2008 "core" standards determined in accordance with the GB/T 8190 regulations We need to identify additional requirements for reciprocating internal combustion (RIC) and the power of the methods set exhaust emission tests. This standard also provides for determining the pre-adjustment of the engine at a variable atmospheric conditions power correction method. The Amendment Act does not apply to determine exhaust Pollutant emission values, because it is only with the engine power is not corrected at all the relevant circumstances. This standard applies to land use, marine and rail traction reciprocating internal combustion engine, but does not include mainly used for road vehicle engines. This standard Suitable for driving, such as machinery, earthmoving machinery, industrial trucks and other road engine applications. This standard is a "satellite" standard, only for use with GB/T 21404-2008 "core" standards, in order to fully provide for specific uses hair Motivation technical requirements.
