Four-stroke internal combustion engine cylinder

Abstract

The invention relates to the technical field of internal combustion engines, in particular to a four-stroke internal combustion engine cylinder. The four-stroke internal combustion engine cylinder comprises a cylinder body, an ignition plug is fixedly connected to the center of the upper end of the cylinder body, an oil spraying pipe is fixedly connected to the position, close to the left side, of the upper end of the cylinder body, and an air inlet pipe is fixedly connected to the position, close to the upper end, of the left side of the cylinder body. An exhaust pipe is fixedly connected to the position, close to the upper end, of the right side of the cylinder body, first one-way valves are fixedly connected to the upper ends inside the air inlet pipe and the exhaust pipe, a motor is fixedly connected to the position, close to the lower end, of the right side of the cylinder body, a machine shaft is rotationally connected to the left side of the motor, and a cam is fixedly connected to the left side of the machine shaft, and the left side of the cam is rotationally connected with a push rod; and a piston of each one-way valve is driven by rotation of a reciprocating lead screw to extrude gas entering the internal combustion engine cylinder in advance, the density of the gas is increased, in this way, when the stroke of gasoline is exploded, the effective power is increased, the fuel efficiency of the gasoline is improved, and the practicability of the device is improved.

Description

technical field [0001] The invention relates 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, compression of the mixture, to the expansion of the gas generated by combustion to drive the piston, and finally to discharge the burned exhaust gas, this process is divided into four steps: Gas stroke, compression stroke, explosion stroke, exhaust stroke. [0003] Existing patent (notification number: CN110159423A) a four-stroke internal combustion engine cylinder, the invention belongs to the technical field of internal combustion engines, specifically a four-stroke internal combustion engine cylinder, including a cylinder, a cylinder chamber, a crank chamber, a cylinder inlet, an air intake door, exhaust valve, first intake manifold, exhaust manifold, ...

AI Technical Summary

Problems solved by technology

[0004] In the above, the exhaust gas is used as the source of power, which speeds up the discharge of exhaust gas, so that the exhaust gas can be utilized. However, when the internal combustion engine works in plateau areas, the combustion of oil is not sufficient due to the low air density, which results in a waste of resources. Waste, economic loss, and cause air pollution at the same time, on some farming machines, the demand for power is greater:
