8. Idle test on engine
Engine test is a process in which engine running-
in and performance are tested in an all-round
manner. The running-in process of the engine
allows all parts of the engine to reach final
precision and coordinate with each other.
Performance testing allows final adjustments to
engine performance.
The engine dynamometer or the chassis
dynamometer may be used for engine test. In
case that dynamometer is not available, the
engine test must be conducted by simulating
dynamometer test.
The dynamometer shall be checked first before
testing. The dynamometer must be able to test the
engine performance when the engine is running
at maximum rotating speed and full power.
Minimum idle speed of engine----------800 r/min
Maximum idle speed of engine -------2,650 r/min
