Problems solved by technology

[0008] With regard to present gas distribution mechanism, its basic problem is that there is a commonplace, and the inventor thinks it is very critical, and is the problem that must be solved: when current internal combustion engine enters and exhausts, only the corresponding air gate is opened to carry out the intake. , Exhaust, the other valve is closed by the closed valve and idle, can not be fully utilized, this is the root cause that the flow area of ​​the intake and exhaust cannot be greatly increased, just like a person exhales through one nostril, and inhales through the other nostril Breathing out of breath always feels like suffocation

Abstract

The invention discloses a valve mechanism of engine, its cylinder head and its operation method. The cylinder head on which the valve mechanism is disposed comprises valves, an intake passage and an exhaust passage. The cylinder head is designed as layered structure, the lower layer involves valves, the middle layer is divided into a leftward air passage and a rightward recover passage, wherein the air passage is provided with an air valve, the recover passage is provided with a recover valve, the upper layer involves a leftward intake passage and a rightward exhaust passage, wherein the intake passage is provided with an intake valve, the exhaust passage is provided with an exhaust valve. A common passage for intake and exhaust is disposed in the middle of the cylinder head. It can reduce the resistance during admission and discharge, and can perform scavenging.

Description

technical field [0001] The invention relates to a gas distribution mechanism of an internal combustion engine, in particular to a gas distribution mechanism capable of reducing intake and exhaust resistance and a method for realizing the mechanism. Background technique [0002] Usually, the gas distribution mechanism is composed of two parts: the cylinder head and the driving device of the outer valve of the cylinder head. In the cylinder head, there are intake passages, exhaust passages, valves, auxiliary parts and partial driving devices to ensure the reciprocating movement of the valves, such as rocker arms or camshafts; the driving devices of the outer valves of the cylinder head are generally camshafts, tappets or only The chain, belt or gear that drives the camshaft, etc. With the continuous development of technology, an electromagnetic valve drive (EVA for short) has appeared to drive the opening and closing of the valve. The driving device of the valve greatly simpl...
