Original Abstract

This paper presents a study of an influence of crankshaft counterweights size upon the engine block load. The engine block load is significantly affected by crank train inertia forces and moments mainly at higher engine speed. This load can be reduced by means of crankshaft counterweights and their appropriate design. The influence of counterweights design upon the engine block load is examined on an in-line four-cylinder naturally aspirated engine in consideration of internal moments of crank train rotating parts. For the analysis are used state-of-the-art methods such as CAD, Finite Elements Method and Multi-body System tools which incorporate flexible bodies, and a computation model of hydrodynamic bearing dynamics.
