Abstract:

The principle of the indicated mean effective pressure (IMEP) method to measure the piston assemblycylinder friction was derived, and the method for calculation of the inertia force of piston assembly and connecting rod was obtained. Then, a reliable transmission of connecting rod stress signal was achieved using wireless transmission method, and piston assemblycylinder friction forces were measured at a range of engine operating speed under motored conditions.

Key words: combustion engine, piston assembly； friction force； indicated mean effective pressure (IMEP)； wireless transmission
