The engine crankshaft bearing is an important component and vulnerable part of engine. Its operating condition significantly influences the dynamic performance, efficiency and overall reliability of the engine. In modern engine design, the main objective is to improve power output while minimizing friction losses and reducing fuel consumption. This present work concerns the study of the behavior in dynamic mode of the big-end and small-end bearings of connecting rod in internal combustion engine, taking into account the rupture and reformation of the fluid film in the contact region in the inactive cavitation zone. The most important operating parameters for the finite length case are calculated and compared to those obtained in the case of a short bearing hypothesis for the two types of connecting rod bearings: big-end and small-end. Solving the hydrodynamic lubrication problem in transient mode is carried out using the Booker mobility method, which is a fast and precise method using a computer language implemented in FORTRAN.

Keywords: hydrodynamic bearing, crankshaft, method of mobility, big-end, small-end, combustion engine.
