Experimental Determination of the Moments of Inertia of an Internal Combustion Engine and its Support Stiffness Constants

Abstract

 The research aims to determinate the inertia moments for an internal combustion, four cylinder and four-stroke engine experimentally. The internal combustion engine studied will also be linked to the gearbox by suspending the engine on a solid axle and considering it as a rotating pendulum. The stiffness constants of the four pivot points of the engine (legs)will be determined using a hydraulic piston specially designed for this purpose. All previous calculations were done according to the three main coordinate axes X, Y, Z. The two tables (4-4) and (4-10) show the values of both the inertia moments and the comparison between the theory and practically values of the stiffness constants
