rotary engine

Abstract

The invention provides a rotor engine. The rotor engine comprises a rotor shell, a rotor cover, a main shaft, a secondary rotor guide wheel, a guide wheel cover and a guide wheel shell, wherein a main rotor and a secondary rotor are arranged in the rotor shell; the secondary rotor is contacted with the outer side of the main rotor, and fits the main rotor to rotate; the rotor shell, the main rotor and the secondary rotor are formed to a combustion chamber; a guide groove is formed in the secondary rotor guide wheel; a guide connecting rod is slidingly connected into the guide groove; the guide connecting rod is fixedly connected to one end of the secondary rotor; and the secondary rotor fits the main rotor to rotate under the guidance of the secondary rotor guide wheel, and controls an adjusting column of the combustion chamber to extend and move to change the volume of the combustion chamber. The rotor engine adjusts the volume of the combustion chamber according to the sucked oil and gas amount; and when the output power is changed, the oil and gas mixing rate and the compression rate in the combustion chamber are always kept in an optimal state.

Problems solved by technology

[0002] When the traditional piston engine is working, the reciprocating motion of the piston is converted into rotary motion through the crank-connecting rod mechanism. The change of the piston movement and the change of the force arm of the crank-connecting rod motion is a sinusoidal curve. When the ignition and deflagration occur, the cylinder pressure is the highest but the force arm is small. The generated torque is also small, and the movement characteristics of the piston prevent the energy of the gas explosion from being released in time, and a considerable part of the energy is dissipated in the form of heat energy, which is not efficient

[0003] The triangular rotor engine has no crank connecting rod mechanism, and uses gas pressure to drive the triangular rotor and eccentric shaft to rotate, but the structure of the triangular rotor and eccentric shaft determines that the output arm is small, the output torque is also small, and the structure of the combustion chamber also makes the Fuel does not burn fully

[0004] At present, the volume of the combustion chamber of the piston engine and the triangular rotor engine is fixed, and the setting of the engine compression ratio can only be selected to favor a certain characteristic.

Especially for the current turbocharged gasoline engine, the compression ratio setting is generally lower than that of the naturally aspirated engine to obtain greater power output at high boost, but the lower compression ratio at low speed will seriously reduce the power

When the output power changes with a fixed combustion chamber volume, it is difficult to take into account that the fuel-air mixture ratio and cylinder pressure are both in the best state, but in practical applications, the output power is mostly constantly changing, so the engine is not in the best fuel most of the time. work in state
