The present paper describes a methodology devised to study the engine block displacement of an internal combustion engine in the radial direction due to combustion force and inertia forces. The combustion force produced in in-cylinder is a substantial function of angular displacement and then correlated with pressure and temperature. Other than the substantial function, combustion force depends on chamber design, injection parameters, flow patterns and fuels. But inertia is a function of angular displacement and a mass of reciprocating parts. Speed is directly related to combustion by means of indicated pressure and the indicated torque respectively. The engine was taken for an analysis along with speed and load as the design variables. The engine block displacement, time-domain frequency, wave form, side thrust and in-cylinder force were examined for the analysis. The results obtained provide the combined effect of combustion force and inertia force induced displacement, uncertainty in combustion processes, nonlinear vibration of the engine block, and vibration spectra. This new approach in engine parameter design bestows insight with the combustion force and inertia induced vibration and source of noise in the diesel engine.
