GB/T 16936-2007Earth moving machinery -- Engine test code -- Net power (English PDF)

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.
