Embodiment 1
[0027] The small circulating return water passage 1 is a through hole arranged on the top of the cylinder block, and its position is between the sprocket chamber and the cylinder water chamber.
[0028] The purpose of this structure is to save space and facilitate the arrangement of the structure of the small circulation return water channel 1 on the engine.
Embodiment 2
[0030] The diameter of the through hole of the small circulation backwater channel 1 is Φ16˜Φ20.
[0031] The aperture of the small circulation return water channel 1 is in the range of Φ16-Φ20, which ensures the small circulation cooling of the engine block, while the flow rate of the water pump is not too large.
[0032] Use holes around Φ16~Φ20 on the top of the cylinder to return all the circulating water that has participated in cooling to the water pump, and use the position between the sprocket chamber and the water chamber of a cylinder to optimize the arrangement of a long channel to make the small circulation in the cylinder backflow. Water no longer affects the combustion in the cylinder, and the cycle structure is compact to save space.
Embodiment 3
[0034] In order to achieve the same purpose of the invention as the above-mentioned technical solution, the present invention also provides the cooling method adopted by the above-mentioned engine block water-cooled small circulation structure, and its technical solution is:
[0035] The engine cylinder is fed with water through the double cavity, and the cooling water channel is added to the adjacent two cylinders;
[0036] The cooling water that has participated in the cooling on the cylinder head directly flows back to the small circulation inlet of the water pump through a long strip-shaped return cavity provided between the front end of the cylinder block and the sprocket chamber.
[0037] The left-mounted water pump is arranged to ensure the cooling needs of the cylinder through double-cavity water intake and two adjacent cylinders. The cooling water on the cylinder head does not pass through the cylinder block, but uses the front end of the cylinder block and the sprocke...
