Description
Technical Field
The invention relates to a novel engine. More particularly, the present invention relates to a single cylinder helical flow engine.
Background
An engine is a machine capable of converting other forms of energy into mechanical energy, and traditionally includes internal combustion engines, external combustion engines, electric motors, and the like. The engine may refer to either the power generation device or the entire machine including the power device. Engines were first introduced in the united kingdom, so the engine concept was also derived from english, and his meaning refers to "power generating machinery".
At present, there are commercially available generators whose operating principle is not more than two, two-stroke engines and four-stroke engines. The working principle of the two-stroke engine is as follows: the engine cylinder is provided with three holes, namely an air inlet hole, an exhaust hole and a scavenging hole, the three holes are respectively closed by a piston at a certain moment, and the working cycle of the engine cylinder comprises two strokes: in the first stroke, the piston moves upwards from the bottom dead center, after the three air holes are closed simultaneously, the mixed gas entering the cylinder is compressed, and when the air inlet hole is exposed, the combustible mixed gas flows into the crankcase; in the second stroke, when the piston is compressed to near the top dead center, the spark plug ignites the combustible mixture, the gas expands to push the piston to move downwards to do work, the air inlet is closed, the combustible mixture sealed in the crankcase is compressed, the exhaust hole is opened when the piston is close to the bottom dead center, the waste gas rushes out, the air vent is opened subsequently, the combustible mixture subjected to prepressing rushes into the cylinder, the waste gas is expelled, and the air exchange process is performed. The working principle of the four-stroke engine is as follows: the working cycle of the gasoline engine consists of 4 piston strokes, namely an air inlet stroke, a compression stroke, a power stroke and an exhaust stroke, wherein the air inlet stroke, the air inlet valve, the exhaust valve and the piston move from a top dead center to a bottom dead center, the volume of a cylinder above the piston is increased to generate vacuum degree, the pressure in the cylinder is reduced to be lower than the air inlet pressure, gasoline atomized by a carburetor or a gasoline injection device is mixed with air to form combustible mixed gas under the action of vacuum suction, and the combustible mixed gas is sucked into the cylinder by an air inlet channel and the air inlet valve. The intake process continues until the intake valve closes after the piston passes bottom dead center. Then the upward piston starts to compress gas; in the compression stroke, the inlet valve and the exhaust valve are closed completely, the temperature of the combustible mixed gas in the compression cylinder is increased, the pressure of the combustible mixed gas is increased to about 0.6-1.2 MPa before the piston is close to the top dead center, and the temperature can reach 330-430 ℃; during the power stroke, when the compression stroke is close to the top dead center, a spark plug arranged above the cylinder cover emits electric sparks to ignite the compressed combustible mixed gas, the combustible mixed gas emits a large amount of heat after being combusted, the pressure and the temperature of the gas in the cylinder rapidly rise, the highest combustion pressure can reach 3-6 MPa, the highest combustion temperature can reach 2200-2500 ℃, high-temperature and high-pressure gas pushes the piston to rapidly move towards the bottom dead center, the piston applies power to the outside through a crank-link mechanism, and when the power stroke starts, the air inlet valve and the air outlet valve are both closed; the exhaust stroke, when the working stroke is close to the end, the exhaust valve is opened, because the pressure in the cylinder is higher than the atmospheric pressure at this time, the high-temperature waste gas is rapidly discharged out of the cylinder, the stage belongs to the free exhaust stage, the high-temperature waste gas is discharged through the exhaust valve, the exhaust process enters the forced exhaust stage along with the exhaust process, the piston moves to the top dead center beyond the bottom dead center, the waste gas in the cylinder is forcibly discharged, when the piston reaches the vicinity of the top dead center, the exhaust process is finished, when the exhaust is finished, the gas pressure in the cylinder is slightly higher than the atmospheric pressure, about 0.105-0.115 MPa, the temperature of the waste gas is about 600-900 ℃, because the combustion chamber occupies a certain volume, the waste gas cannot be completely discharged completely when the exhaust is finished; the four-stroke gasoline engine completes one work cycle through four strokes of air intake, compression, work application and exhaust, and in the process, the piston reciprocates up and down for four strokes and the corresponding crankshaft rotates for two circles.
Therefore, no matter the two-stroke engine and the four-stroke engine are adopted, the function conversion efficiency is low in terms of the working principle, only part of strokes do work, the rest strokes complete air intake, air compression and air exhaust, the processes do not do work, the efficiency of the engine is low, the rotating speed limit value is small, and the multi-cylinder multi-stroke setting volume is large. The gas discharged by the traditional engine only can be waste gas, and can not do work and be recycled, and the environment is polluted, so that the traditional engine is harmless and not beneficial.

2. The single cylinder helical flow engine of claim 1, wherein said drag lobe area is 0.366 of the cross-sectional area of the helical air path.
3. The single cylinder, helical airflow engine of claim 2 further comprising:
arranging a two-stage pressurizing device, wherein high-pressure gas generated by an air compressor enters an oil tank to generate high-pressure mixed oil gas, and the high-pressure mixed oil gas enters an oil-gas mixing tank to finish one-stage pressurizing;
the high-pressure mixed oil gas is conveyed to an oil nozzle through a transmission metal oil gas guide pipe and a heating metal oil gas guide pipe, the heating metal oil gas guide pipe is wound on the outer part of the cylinder body, and the heating metal oil gas guide pipe is heated and pressurized through the self heating of an engine to complete secondary pressurization;
three-stage high-pressure-resistant backflow valves are arranged between the oil tank and the transmission metal oil gas guide pipe, between the transmission metal oil gas guide pipe and the heating metal oil gas guide pipe and in front of the oil nozzle.
4. The single-cylinder spiral airflow engine of claim 3, wherein before the high-pressure mixed oil gas enters the transmission metal oil gas guide pipe, oxygen is input into the oil gas mixing box through a small oxygen generator, and the oxygen content of the mixed oil gas is increased by 5-10%.
5. The single cylinder helical air flow engine of claim 3 wherein said fuel injector has two types of ignition means, a compression ignition means and a timing ignition means, the first ignition using the timing ignition means.
6. The single-cylinder helical airflow engine according to claim 4 or 5, characterized in that a pressure-limiting and pressure-fixing gravity valve is arranged at the front end of the oil nozzle, and the pressure-limiting and pressure-fixing gravity valve is closed at the moment of gasoline explosion; when the pressure of the combustion chamber is lower than a preset threshold value, the pressure-limiting and pressure-fixing gravity valve is opened under the action of gravity, and oil and air are fed; and when the pressure of the combustion chamber is lower than a preset minimum value, the pressure ignition device starts ignition.
