Study on the Method of Measuring the Inertia Moment of Multi-Cylinder Engine

Inertia moment of engine is a quite important parameter for power measuring without load, instantaneous speed calculating and in cylinder pressure reconstruction. In order to get this important parameter, a new method named instantaneous speed fluctuation comparison is brought out. The detail theory and approach is introduced. After experiment on the 6135 diesel, the validity of the method is proved, and the error of the method is analyzed.
