An auto-bike water-cooling engine is composed of a cylinder, a cylinder head, and a pump, wherein the cylinder is composed of a cylinder cover and a cylinder heat elimination cover. The utility model is characterized in that: a current circulation chamber is formed between the cylinder hear elimination cover and the cylinder shell; two water-cooling channels communicated with the current circulation chamber are arranged on the cylinder head where a water inlet and a water outlet is arranged; the water inlet is communicated with a water-cooling channel; and the water outlet is communicated with the other water-cooling channel. As the technic proposal is adopted, the utility model has the advantages of long service life and large cooling area, thus the utility model can make the cooling water circulate and be cooled between the cylinder and the cylinder head with the cooling effect clearly increased and the 'pulled cylinder' of the piston as well as valve broke due to the too small distance between the piston and the cylinder avoided and also with the piston being burned avoided; besides, the utility model can realize wind cooling, increase the cooling effect, and solve the problems of valve rod broken, piston penetrated, and the connecting rod bend.
