Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of power machinery, and particularly relates to a single-cylinder power device adopting a ring-shaped stroke. BACKGROUND

[0002] An internal combustion engine is a heat engine that generates power by burning fuel inside a machine and directly converting the heat energy released by the fuel into power. Generally speaking, an internal combustion engine refers to a piston internal combustion engine.

[0003] The piston internal combustion engine is the most common reciprocating piston type. The piston internal combustion engine mixes fuel and air and burns them in its cylinder, and the heat energy released by the burning causes high-temperature and high-pressure gas in the cylinder. The gas expands to push the piston to work, and then the mechanical work is output through a crankshaft connecting rod mechanism or other mechanisms to drive the driven machinery to work.

[0004] The fuel used by the piston internal combustion engine is mainly gasoline, diesel, natural gas, etc. The main components of gasoline are C5-C12 aliphatic hydrocarbons and naphthenes, and complete combustion generates CO2 and H2O, incomplete combustion generates CO and C, and also generates pollutants such as nitrogen oxides and sulfur oxides; diesel contains oxygen, silicon, aluminum, iron, calcium, sulfur, nitrogen, hydrogen, carbon, etc., and complete combustion generates CO2 and H2O, incomplete combustion generates CO and C, and also generates pollutants such as nitrogen oxides and sulfur oxides; natural gas contains carbon and hydrogen elements, and the complete combustion product is CO2 and H2O, and the incomplete combustion product is CO and C; in summary, all three fuels will produce carbon dioxide or carbon monoxide, and excessive emission of carbon dioxide is the main cause of greenhouse effect, global warming, glacier melting, and sea level rise, and carbon monoxide itself is a toxic gas.

[0005] Therefore, the piston internal combustion engine generally has problems such as high emissions and serious pollution; and the new energy fuel that can replace fuel still produces carbon dioxide, and although renewable alternative fuels have low emissions and low pollution, there are still problems such as technical threshold, immature technology, high cost, and difficult to meet market demand in terms of range.

[0006] The piston internal combustion engine uses gas expansion to push the piston to work, and then outputs mechanical work through a crankshaft connecting rod mechanism or other mechanisms. This mechanical transmission structure needs to convert the reciprocating linear mechanical movement of the sliding plug into circular motion, and the transmission efficiency is not high, which makes the thermal efficiency of the fuel low and causes a certain degree of waste.

Thus, the power stroke is completed.

[0068] After the power stroke is completed, the first limiting slide 13 is lowered to reset, and the exhaust gas exhaust valve port 10 is opened. With the rotation of the rotor slide 4, the burned exhaust gas is forced to be discharged. After the rotor slide 4 passes the second limiting slide 3, the second limiting slide 3 is lowered to reset.
