Rotary piston engine

Abstract

The invention relates to an engine, in particular to a rotary piston engine which comprises an annular air cylinder and two rotators, wherein each rotator is provided with a plurality of pistons, and the two groups of the pistons are arranged in the air cylinder at intervals and divide the air cylinder into a plurality of work rooms with variable volumes; a rotor (2) is arranged on an eccentric shaft neck of an output shaft (1), revolves around the rotating center of the output shaft and auto-rotates around the center of an eccentric shaft neck (1a) on the output shaft; both ends oppositely arranged around the auto-rotating center at 180 degrees on the rotor and the two rotators in the air cylinder are respectively connected in a controllable mode; when the output shaft and the rotor are rotated at a uniform speed, the two rotators are rotated at a rotating speed of cyclical fluctuation, and the pistons on the rotators move with the rotators, thus two adjacent pistons are continuously closed and separated mutually; and the work rooms of the engine sequentially finish four strokes of the work of the engine.

Description

Technical field: [0001] The invention relates to an engine, in particular to a rotary piston engine. Background technique: [0002] The traditional four-stroke piston reciprocating engine relies on the combustion of fuel in the combustion chamber to push the piston to reciprocate up and down or horizontally, and then convert the linear motion of the piston into the rotation of the crankshaft through the connecting rod and crankshaft. The main disadvantages of this engine are 1. The structure is complex, bulky and heavy. 2. The reciprocating inertial force and moment of inertia caused by the reciprocating motion of the piston in the crank-connecting rod mechanism cannot be completely balanced. The magnitude of this inertial force is proportional to the square of the speed, which reduces the smoothness of the engine's operation and limits the development of high-speed engines. 3. Since the working method of the four-stroke reciprocating piston engine is that three of the four...

The main disadvantages of this engine are 1. Complex structure, large volume and heavy weight

2. The reciprocating inertial force and moment of inertia caused by the reciprocating motion of the piston in the crank-connecting rod mechanism cannot be completely balanced. The magnitude of this inertial force is proportional to the square of the speed, which reduces the smoothness of the engine's operation and limits the development of high-speed engines.

3. Since the working method of the four-stroke reciprocating piston engine is that three of the four strokes completely rely on the inertial rotation of the flywheel, resulting in very uneven power and torque output of the engine, although modern engines use multi-cylinder and V-shaped arrangements. reduce this shortcoming, but it is impossible to eliminate it completely

However, because the combustion chamber of this engine is not very conducive to the combustion and diffusion of fuel, the fuel consumption rate is high and the exhaust emissions are more pollutants. For diesel engines, this severely limits the popularization and application of the rotary engine
