Nonlinear kinematics of engine crank-piston mechanism

Abstract

The paper deals with nonlinear kinematic behaviour of engine crank-piston mechanism. The basics of crank-piston mechanism’s dynamic are presented, followed by analysis of nonlinear kinematic relations connected to kinematic operation of crank-piston mechanism. Simulation of nonlinear kinematics of the crank-piston mechanism of Lombardini 3LDA 450 engine was performed, especially for the piston position, velocity and speed. Corresponding conclusions were drawn.
