The method developed in an earlier work describing the dynamic behavior of an elastic connecting-rod bearing was used to compare the performance (minimum film thickness, torque and flow rate) of two different bearings which belong respectively to a petrol and a diesel engine. Results show that of all the mechanical factors considered (load, speed, viscosity . . . ), the most significant parameter is the load diagrams, which through the elastic deformation governs the film thickness distribution.
