Background

When the engine of the motorcycle works, the friction surfaces (such as crankshaft journal and bearing, camshaft journal and bearing, piston ring and cylinder wall, timing gear pair, etc.) move relatively at a high speed, and the friction between the metal surfaces not only increases the power consumption in the engine and leads the working surfaces of the parts to be worn quickly; the heat generated by friction may also melt the surfaces of certain working parts, causing the engine to fail to operate properly. Therefore, in order to ensure the normal operation of the engine, the surfaces of the relatively moving parts in the engine must be lubricated, that is, a layer of lubricant (engine oil or grease) is covered on the friction surface, so that a thin oil film is spaced between the metal surfaces, thereby reducing the friction resistance, reducing the power loss, reducing the abrasion and prolonging the service life of the engine.

The oil reservoir 17 includes an oil reservoir 171, the bearing 151 is at least partially disposed in the oil reservoir 171, and the bearing 151 can contact the lubricating oil in the oil reservoir 171. In the embodiment of the present application, the engine 100 employs a splash lubrication method or a combination of a splash lubrication method and a pressure lubrication method to lubricate the internal structure of the engine 100. Through the arrangement, when the engine 100 performs splash lubrication, the oil storage mechanism 17 can collect splashed lubricating oil through the oil storage groove 171 and convey the splashed lubricating oil to the bearing 151, so that the lubricating degree of the engine 100 on the bearing 151 is improved, the abrasion of the bearing 151 during operation is reduced, and the service life of the bearing 151 is prolonged. It is understood that the lowest point of the upper surface of the oil reservoir 171 may be higher than the lowest point of the bearing 151 in the up-down direction of the engine 100, thereby facilitating the flow of the lubricating oil from the oil reservoir 171 to the bearing 151 and improving the lubricating effect of the bearing 151.
