Abstract: In view of the fact that the traditional dynamometer can not test diesel engine power in the production site, based on the principle of No-Load Power Measuring, a mathematical model between the maximum power of diesel engine and crankshaft speed, equivalent moment of inertia and acceleration time was established. And a set of diesel power test system was set up in which the NET2801 data acquisition card is the core. The time-speed curve of the diesel engine acceleration and deceleration process is obtained by MATLAB software programming. The equivalent moment of inertia and the maximum power of the diesel engine are deduced. The reliability of the test method is verified and the cause of the error is analyzed, which provides a research idea to improve the field test accuracy of diesel engine power.

Keywords: diesel engine power, No-Load Power Measuring, equivalent moment of inertia, Instantaneous speed
