Abstract
The Use of smaller crankshaft bearings is known to reduce the frictional loss for automobiles, resulting in improved fuel economy. However, the bearing life deteriorates when bearing size is reduced, unless engine output is also reduced.
In order to provide design information on this subject, engine tests have been conducted to evaluate the effects of the pressure of bearing projected area, sliding velocity, oil temperature, type of bearing metals and other factors, on the bearing life. As a result of this study, guidelines for selection of bearing size were obtained.
