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.

3.1
net power
power obtained on a test bed at the end of the crankshaft or its equivalent at the
corresponding engine speed with the equipment and auxiliaries listed in Table 1.
NOTE. If the power measurement can only be carried out with a mounted gear-box, the losses in the
gear-box should be added to the measured power to give the engine power.
3.2
standard production equipment
any equipment provided by the manufacturer for a particular engine application.
