First we from engine of power performance aspects to, engine once started should is very ideal of State, may something started Hou cannot normal run but without worried this belongs to normal phenomenon, that we on should check started Qian we whether do has the prepared measures, if we started Qian of prepared work do have very perfect, so a Taiwan quality of engine three times within started and normal running, or the engine performance bad.

　　Following introduction of the second method, load diesel engine idling operation after a period of time, gradually increasing speed and the load and power measuring instrument to determine the power requirements are met. If no dynamometer some grass-roots units, in circumstances beyond our measurement of diesel power, diesel engine can be used with manual, are simple judgement. This is because the manual is often discussed in accordance with diesel engines the power output, therefore, as long as when the engine supporting the smooth machine at rated speed mathematics; speed is not high or low, can illustrate the power of diesel engines meet the stipulated requirements.

　　Note that machines should be continuous operation 2-3h, and power did not change is recognized. At load time, also check the coolant temperature and oil pressure is normal. Try again Governor is flexible. Methods are suddenly removed with machines, speed to see if it can soon return to the rated speed, should generally be less than 15s reach. Also after going to see speed increases, the maximum speed is. General maximum speed shall be 110% of the rated speed, tachometer measurement available. If these meet the requirements can be considered good quality diesel engines being tested.
