Four-stroke internal combustion engine gas cylinder

Abstract

The invention belongs to the technical field of internal combustion engines, and particularly relates to a four-stroke internal combustion engine gas cylinder which comprises a gas cylinder, a gas cylinder chamber, a crankshaft chamber, a gas cylinder gas inlet, a gas inlet door, a gas exhaust door, a first gas inlet manifold, a gas exhaust manifold and a second gas inlet manifold. The first gas inlet manifold is arranged at one end of the gas cylinder; the gas exhaust manifold is arranged at the other end of the gas cylinder; the gas inlet door communicates with the first gas inlet manifold;the second gas inlet manifold is arranged between the first gas inlet manifold and the crankshaft chamber; the gas exhaust manifold communicates with the gas exhaust door; and the gas cylinder gas inlet is formed at the position, close to the gas cylinder chamber, of the crankshaft chamber. The four-stroke internal combustion engine gas cylinder further comprises a power unit, a gas exhaust unit,a transmission unit and a gas supplementing unit, wherein the power unit is located in the gas exhaust manifold and is used for collecting energy of waste gas; the gas exhaust unit is located on the gas exhaust door and is used for accelerating the exhaust of the waste gas; the transmission unit is located on one side of the power unit and is used for power transmission of the power unit; and thegas supplementing unit is located in the second gas inlet manifold and is used for supplementing gas into the crankshaft chamber.

Description

technical field [0001] The invention belongs to the technical field of internal combustion engines, in particular to a four-stroke internal combustion engine cylinder. Background technique [0002] The operation of the four-stroke internal combustion engine (engine), that is, from the intake of the mixture of fuel and air, the compression of the mixture, the expansion of the gas generated by the combustion to drive the piston, and finally the discharge of the burned exhaust gas, this process is divided into four steps: [0003] (1) Intake stroke: the piston goes down and the intake valve opens, and the mixture of air and fuel (gasoline, etc.) is sucked into the cylinder. [0004] (2) Compression stroke: the intake valve is closed and the piston is upward, compressing the mixture to make its volume smaller. [0005] (3) Explosive stroke: ignite in the compressed gas mixture, make the gas combust and explode, and push the piston down (doing work). [0006] (4) Exhaust stroke...

Problems solved by technology

However, the valve body control of this type of four-stroke internal combustion engine cylinder is too complicated, and when the piston passes through the cylinder intake port, the piston sealing device is prone to wear and tear. Therefore, we have proposed a four-stroke internal combustion engine cylinder to solve the above problems
