Cylinder head structure of vertical water-cooled engine

Abstract

The invention relates to a cylinder head structure of a vertical water-cooled engine. The engine comprises a cylinder head, a cylinder body and a crank case. The lower end of the cylinder body is arranged on the crank case, and the cylinder head is arranged at the upper end of the cylinder body. A cylinder head cooling liquid sleeve used for cooling a combustion chamber and a waste gas channel is arranged on the cylinder head, and the cylinder head is provided with a gas inlet channel, an exhaust channel, an engine valve transmission chamber and an igniter. The cylinder hole axis of the cylinder body slightly inclines relative to the ground perpendicular line, and a gas inlet of the gas inlet channel of the cylinder head is higher than an exhaust outlet of the exhaust channel. The igniter is mounted in an oblique inserting mode relative to the cylinder hole axis of the cylinder body, and when being laterally looked from the engine valve transmission chamber, the part, located within the cylinder body cylinder diameter phantom line range where a cylinder hole of the cylinder body extends to the cylinder head, of the cylinder head cooling liquid sleeve is in a lying E shape; cooling liquid is discharged from a discharge outlet of a cooling liquid discharging channel at the gas inlet channel side, a concave opening part is formed between the cooling liquid discharging channel and the peak of the cylinder head cooling liquid sleeve, a gas guiding channel is arranged above the concave opening part and vertically spaced from the concave opening part, and the gas guiding channel is provided with a guiding-in end communicated with the peak and a guiding-out end communicated with the liquid discharging channel; the guiding-out end is higher than the guiding-in end.

Description

technical field [0001] The present invention relates to a cylinder head structure of a vertical water-cooled engine, especially a vertical cylinder head structure that can prevent the vaporized body of the cooling liquid from accumulating in the cooling liquid jacket of the cylinder head and cause air plugging, thereby improving the efficiency of the engine. The cylinder head structure of a water-cooled engine. Background technique [0002] Korean Patent No. 10-0395016 was proposed in order to solve the problem of vaporization deposition after the cooling liquid of a vehicle liquid-cooled vertical cylinder engine vaporizes. [0003] Such as figure 1 , 2 As shown, the Korean Patent No. 10-0395016 is to protrude a protruding part 12 on the cylinder head 11 of the engine 1, and the protruding part 12 is provided with an accommodating chamber 121, and the accommodating chamber 121 communicates with The cooling liquid channel 13 ; whereby when the cooling liquid circulating in...

AI Technical Summary

Problems solved by technology

However, the protruding portion 12 is protruding from the cylinder head 11, so the volume of the cylinder head 11 will increase, which will cause interference between the cylinder head 11 and other components, and make the configuration and design of other components difficult. degree increase

[0005] Therefore, how to avoid installing a cooling liquid vaporization mechanism on the cylinder head, which causes the cylinder head to interfere with other components, has become an urgent problem for vehicle manufacturers to overcome.
