<p>This explanation describes examples of fuel economy improvement technologies that have been applying engine bearings. In order to improve the fuel economy of automotive, it is very important to reduce the friction of engine bearings, and many technologies have been applied. The method as means low friction, by reducing the amount of oil to the engine bearings, the smaller the oil pump capacity, reducing the torque throughout the engine system, and coating a solid lubricant on the surface of the bearing, there is a method of reducing the friction at the time of starting the engine is stopped. Furthermore, in order to reduce the fluid friction during cold, a technology that realizes an early temperature rise of the oil film interposed between the crankshaft and the bearings is used. In this paper, these technical examples are introduced, and finally, future technical trends and prospects for engine bearings are described.</p>
