Problems solved by technology

[0002] The role of the valve is to input fuel into the engine and discharge exhaust gas. The traditional engine has only one intake valve and one exhaust valve per cylinder. This design structure is relatively simple, low cost, easy maintenance, and low-speed performance. Better, the disadvantage is that the power is difficult to increase, especially at high speeds, the inflation efficiency is low and the performance is weak

Embodiment Construction

[0013] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0014] Such as figure 1 Shown, a kind of multi-notch type valve, comprises valve 1, strip groove 2, valve stem 3, it is characterized in that, the valve stem 3 of described valve 1 is provided with strip groove 2, and described strip groove 2 It is arranged on the circumference of the valve stem 3, the cross-sectional structure of the valve stem 3 is quincunx, and the transverse notch of the bar-shaped groove 2 is fan-shaped.

[0015] Wherein, the number of bar-shaped grooves 2 is multiple, and the sector angle is between 45°-80°. By setting the surface of the valve rod 3 as a notch-like surfa...

Abstract

The invention relates to a multi-notch type valve which comprises a valve body, strip-shaped grooves and a valve rod. The strip-shaped grooves are formed in the valve rod of the valve and formed in the circumference of the valve rod. The cross section of the valve rod is structurally in a plum blossom shape. A transverse notch of each strip-shaped groove is a in a fan shape. The multiple strip-shaped grooves are formed. The fan angle ranges from 45 degrees to 80 degrees. The valve rod is designed to be of a stepped shaft type structure, and the dovetail notches are formed in the step face, so that the service life of the valve is prolonged, the damage of carbon deposition to the valve is avoided, and the phenomenon that a valve guide pipe is too hot to cause carbon deposition is eliminated; and the multi-notch type valve has the beneficial effects of being simple in structure, reducing product weight and meanwhile reducing production cost.

Description

technical field [0001] The invention relates to the field of automobile valves, in particular to a multi-notch type valve. Background technique [0002] The role of the valve is to input fuel into the engine and discharge exhaust gas. The traditional engine has only one intake valve and one exhaust valve per cylinder. This design structure is relatively simple, low cost, easy maintenance, and low-speed performance. Better, but the disadvantage is that the power is difficult to increase, especially at high speeds, the inflation efficiency is low and the performance is weak. In order to improve intake and exhaust efficiency, multi-valve technology is often used now. It is common that each cylinder has 4 valves (there is also a single-cylinder design with 3 or 5 valves, the principle is the same, such as the Audi A6 engine), 4 cylinders in total It is 16 valves. The "16V" that we often see in automobile materials means that the engine has 16 valves in total. This multi-valve ...
