Cooling system of engine cylinder

Abstract

The invention provides a cooling system of an engine cylinder, belonging to the technical field of motorcycle engines and solving the problems of complicated structure, difficult processing, poor stability, and the like of the cooling system of a traditional engine cylinder. The cooling system of the engine cylinder comprises an engine cylinder body with a cylinder hole, one side of the engine cylinder body is provided with a cam chain chamber for mounting a cam chain, heat radiating ribs are arranged at other sides of the engine cylinder body, the cam chain chamber is internally provided with a heat-conducting piece, both outer walls of the heat-conducting piece are respectively attached to the outer lateral wall of the engine cylinder body and the inner lateral wall of the cam chain chamber, and the heat-conducting piece is made from a metal material. The invention has the advantages of good radiation effect, convenient processing and mounting and engine vibration and noise reduction.

Description

technical field [0001] The invention belongs to the technical field of motorcycle engines, and in particular relates to a cooling system for an engine cylinder, in particular to a cooling system for a vehicle four-stroke air-cooled engine cylinder. Background technique [0002] The cooling methods of the vehicle engine mainly include water cooling and air cooling. In the water-cooled engine, the water jacket is mainly designed on the cylinder block; the circulation of the coolant is used to reduce the temperature of the engine cylinder block. In the air-cooled engine, the heat dissipation is mainly used. The contact area between the blade and the air is used to reduce the temperature of the cylinder block, but the cylinder block on the side of the cam chain usually does not use any medium to transfer the heat from the inner surface, which leads to an increase in temperature, and local heating causes the piston to pull easily. , Piston eccentric wear and so on.

AI Technical Summary

Problems solved by technology

Although this structure can play a role in cooling down, if the cam chain chamber is modified, in order to make the oil passage on the cam chain chamber communicate with the oil pump, it is necessary to process oil passages for other parts during production and processing, and It is also necessary to consider the backflow of lubricating oil after the lubricating oil is sprayed on the outer wall of the cylinder. The processing design is troublesome and the production cost is high. At the same time, as long as there is a problem in one of the oil circuits, the cooling system of the engine cylinder block will be greatly affected , it will not even cool down the cylinder block, and the stability is not good
