introduction
This standard and the "core" standard GB/T 21404 used in combination to define the net power calibration earthmoving machinery, related equipment and assistive devices
Consume engine power (fans, pumps, air compressors, etc.) be deducted from the rated power of the engine. Therefore, "Satellite" standard is not a single energy
Single file exists, but rather as a supplement to GB/T 21404 to requirements.
GB/T 21404 contains all the general requirements of the engine, and this standard contains only a particular purpose engine power measurement range is defined
And calibration requirements necessary.
This standard is associated with GB/T 21405 between in Appendix A has been described.
Earthmoving machinery net engine power test specification
1 Scope
The ISO 6165 standard specifies the definition of earthmoving machinery net engine power test specification. The standard end-of earthmoving machinery
Households to provide a net power value reported by standard methods.
This standard applies to.
a) Reciprocating internal combustion engines (spark ignition or compression-ignition engines), excluding free-piston engines;
b) rotary piston engine.
These engines may be naturally aspirated engine, it can be a mechanical supercharger or turbocharger supercharged engine.
Note. This standard is GB/T 21405 matching criteria. Auxiliary means the difference between the two is a matter of principle experiment to install some cooling equipment and compression-ignition
Equipment (fans) are different. By test or calculation methods from GB/T 21405 stipulated engine calibration power to deduct the necessary equipment and auxiliary means
Power opposed. The preferred method of calculation obtained in compliance with this standard engine calibration net power Appendix A. Test and calculation methods are subject to this Standard

Foreword
This standard modifies and adopts ISO 9249.1997 Earth-moving machinery – Engine test
code - Net power (English edition). It includes the technical corrigendum ISO 9249 Cor.
1.1999.
This standard is redrafted according to ISO 9249.1997.
The main technical differences between this standard and ISO 9249.1997 are as follows.
— Take our country's standards to replace the corresponding international standards
which are referenced in ISO 9249.1997.
— Renumber the footnotes from 1a), 1b), 2 ... to a), b), c)... in Table 1.
— Renumber the footnotes of full text. Add the number for the formulas of the full text.
— Add Table 4. The content in Table 8.4 is moved into Table 4, with the renumbering of
its footnotes. The previous Table 4 is changed to Table 5.
— The tolerance values which are expressed by a%, b%, c% and d% are changed to
the form of expression such as a, b, c and d (the a, b, c and d have been defined as
percentages as specified in 9.3.1.4).
For ease of use, the following editorial modifications have been made in this standard.
— “The international standard’ is changed to ‘this standard’;
— The decimal point ‘, ’ is changed into decimal point ‘.’;
— The foreword of the international standard is deleted.
This standard is revision to GB/T 16936-1997 Earth-moving machinery - Engine test code
- Net power.
Compared with GB/T 16936-1997, the main changes of this standard are as follows.
— Contents such as intake pressure drop, absolute pressure of engine import, exhaust
back pressure are added in Clause 5.3;
— In Clause 5.3, the fuel oil temperature is stipulated according to the stipulation of
spark ignition engine and compression ignition engine;

Earth-moving machinery –
Engine test code - Net power
1 Scope
This standard specifies a method for testing internal combustion engines intended for
propulsion of earth-moving machinery as defined in GB/T 8498.
This standard applies to evaluate the performance of earth-moving machinery’s engine. It
is used to introduce, at full load condition, the engine’s characteristic curve of power, fuel
consumption rate versus the rotation speed. These engines may be the natural aspirated
or pressure-charged, either using a mechanical pressure-charger or turbocharger.
This standard concerns internal combustion engines used in earth-moving machinery and
included in one of the following categories.
- reciprocating internal combustion engines (spark-ignition or compression-ignition)
but excluding free piston engines;
- rotary piston engines.
NOTE. This standard provides engine power correction factors in conformity with ISO 1585.1992.
