Abstract
The invention discloses an engine lubricating oil way of a motorcycle. An air cylinder head, an air cylinder body and a crankshaft box are assembled together. An air cylinder head cover and the air cylinder head are fixed through screws. Lubricating oil passes a lubricating oil inlet channel, a vertical small hole and a horizontal hole to flow to a stud threaded hole in the crankshaft box firstly and then flows along stud through holes in the air cylinder head and the air cylinder body to flow to a lubricating oil linear oil channel through a lubricating oil inclined oil channel in the air cylinder head, and the lubricating oil passes through a center hole of a hollow locating pin and then penetrates in the air cylinder head cover. The lubricating oil flows to the lubricating oil linear oil channel through the lubricating oil inclined oil channel and is injected into the air cylinder head cover through four lubricating oil injection holes. According to the engine lubricating oil way of the motorcycle, the lubricating oil is injected out of the lubricating oil injection holes in the air cylinder head cover, and therefore movement parts such as a rocker arm in the air cylinder head cover can be comprehensively and fully lubricated; and the stud through holes and the locating pin are adopted and serve as part of the oil way, and therefore the structure can be simplified under the premise that function requirements are met.
