O-shaped rotary engine

Abstract

An O-shaped rotary engine comprises a gas compressor, a power machine, a flow divider, a gas compressor flow guide and a power shaft. The gas compressor and the power machine have same structures, namely both comprise an I-shaped annular stator with two partition guide holes staggered outside and inside in a middle partitioned portion, and both are provided with two rotors at two ends and comprising trapezoid-like protrusions (pistons) extending into an annular groove, wherein one rotor comprises an outer guide rail while the other rotor comprises an inner guide rail, and the outer guide rail and the inner guide rail respectively clamp a partition with the corresponding pistons and the two lateral annular faces of each piston to enable the partition to axially reciprocate in the partition guide holes to partition the annular groove into two portions with high air tightness. By means of mutual cooperation of all portions of the engine, continuous blasting to directly output shaft work can be realized, and four stokes are completed simultaneously in different cavities. The O-shaped rotary engine is large in power-weight ratio, low in vibration, high in energy conversion efficiency, simple in structure and easy in processing and manufacturing and can be used as an aeroengine.

Description

Technical field: [0001] The invention relates to an internal combustion engine which directly outputs shaft power, in particular to a rotary engine with simple structure, small vibration, high power-to-weight ratio and high efficiency. Background technique: [0002] At present, there are mainly three types of engines that output shaft power that are put into practical application: reciprocating piston engines, triangular rotor engines, and gas turbine shaft engines. The reciprocating piston engine has a simple structure and is easy to expand, but it has several disadvantages: First, it relies on the inertia of the flywheel to maintain the continuity between each stroke, resulting in the need to install a heavy flywheel and reduce the engine's capacity. power to weight ratio. The second, its fuel detonation work time is short so that part of the fuel is discharged without fully burning, resulting in low fuel combustion efficiency. Third, it needs to convert the reciprocatin...

AI Technical Summary

Problems solved by technology

The reciprocating piston engine has a simple structure and is easy to expand, but it has several disadvantages: First, it relies on the inertia of the flywheel to maintain the continuity between each stroke, resulting in the need to install a heavy flywheel and reduce the engine's capacity. power to weight ratio

Second, the detonation and detonation work time of the fuel is short, so part of the fuel is discharged before being fully burned, resulting in low fuel combustion efficiency

Third, it needs to convert the reciprocating motion of the piston into the rotation of the power shaft through the crankshaft, in which part of the mechanical energy will be lost

Fourth, when the crankshaft rotates, the center of gravity shifts, causing the whole machine to vibrate greatly, and the noise is also large

But it also has several disadvantages: First, it needs to rely on complex mechanical devices to convert the motion of the triangular rotor around the power shaft into the rotation of the power shaft, which is not conducive to assembly and maintenance

Second, its triangular rotor needs to move in a cylinder with a special shape. The special shape of the cylinder and the high requirements for air tightness make it difficult to process and produce

Third, the shift of the center of gravity caused by the movement of the triangular rotor around the power axis leads to large vibration and noise of the whole machine

Fourth, due to the complex geometry of the components and the complexity of the transmission, the power-to-weight ratio is low

The gas turbine shaft engine uses the expanded gas to drive the turbine to rotate, which can directly output the shaft work, and there is no center of gravity shifting parts during the rotation, so the vibration is small and the noise is small, but it has several disadvantages: First, the gas turbine shaft engine The exhaust gas still has a high velocity and temperature, resulting in low energy conversion efficiency and high fuel consumption

Second, combustion chambers, gas turbines, and power turbines exposed to high-temperature and high-pressure gas need special materials that are resistant to high temperatures and have strong toughness under high temperature and high pressure. The manufacturing process is difficult and the cost is high, so it is difficult to popularize and promote
