Rotary engine with homocentric arc trapezoid swivel plugs

Abstract

A rotary engine with homocentric arc trapezoid swivel plugs belongs to the technical field of engine manufacture, energy conservation and emission reduction. An elliptic columnar cylinder cavity is enclosed by a cylinder body and end caps, a cylindrical rotor coaxial with the cylinder cavity is arranged in the cylinder cavity, four through grooves with homocentric arc trapezoid cross sections are axially arranged at the outer edge of the rotor along the axial direction of the rotor, and the homocentric arc trapezoid swivel plugs are placed in the through grooves and can rotate around the axes of the swivel plugs. The cylinder cavity is divided into two combustion cavities and two lubrication cavities by the swivel plugs, fuels are combusted in the combustion cavities to generate power, only engine oil and air are sprayed into the lubrication cavities to lubricate the cylinder body, the cylinder end caps and the swivel plugs, and the positions of the cavities are sequentially changed clockwise or anticlockwise along with rotation of the rotor. When the engine works, only pure torque is generated, so that the engine is low in vibration, noise and friction force, sufficient in combustion, low in tail gas pollution and high in overall efficiency, and has great popularization value.

Description

technical field [0001] The utility model relates to a rotary engine with a concentric arc trapezoidal rotary plug, which belongs to the technical field of engine manufacturing and energy saving and emission reduction. Background technique [0002] For more than one hundred years, piston internal combustion engines have been widely used in many power machinery, especially reciprocating piston engines have promoted the development of the automobile industry. The reciprocating piston engine is composed of a cylinder, a piston, a crankshaft, etc. After four strokes, the crankshaft is driven to rotate by the crank between the piston and the crankshaft. The piston reciprocates, while the crankshaft rotates, and when the force on the piston is maximum, the crankshaft torque is zero. The difference in motion mode results in small torque and high friction in many places. In addition to accelerated wear, it also increases additional energy loss, leads to incomplete combustion, and in...

AI Technical Summary

Problems solved by technology

Due to factors such as low efficiency and heavy pollution, the application has been very limited so far

The main problems of the rotary engine are that the air leakage of the cylinder causes the power to drop, and there is still a power transmission mismatch between the planetary piston and the rotating main shaft, that is, the problem of the component force of the vertical main shaft is not solved, resulting in excessive friction and high degree of mechanical damage , short life, etc.
