Width of engine bearings tends to be short because of the reductions in engine size and in power loss. Therefore short bearings, namely high surface pressure bearings, must be studied. In this study, friction of a con-rod bearing is evaluated with a mass conserving elastohydrodynamic lubrication model. Clearance shape, surface texture, and width of the bearing have been investigated. The friction of the bearing with a real clearance is less than that with a circle clearance. The surface textures having the character in circumferential direction have a tendency to lower the friction of the bearing. Property of oil is important especially on the short bearings.
