Description

Engine

Technical Field

The invention relates to the field of heat energy and power, in particular to an engine.

Background

The engine without the crankshaft cylinder piston has the characteristics of high efficiency, simple structure, few friction pairs, good environmental protection, strong fuel diversity and the like, but the practical application of the engine is always limited, and the fundamental reason is that the engine is easy to flameout. The reason for its flameout is that the conventional free piston engine uses the motor to control the compression force of its compression process, which not only requires a very difficult control process, but also requires a motor of too large capacity. If the mass of the reciprocating body is increased, the working reliability of the free piston engine can be improved, but the weight of the system is greatly increased, however, if the kinetic energy is stored by the rotational inertia body (such as a flywheel) which only does swinging rotation, the requirement of the motor to do work in the compression process can be weakened or eliminated on the premise of not excessively increasing the weight of the system, and the working reliability of the free piston engine can be effectively increased. The mechanism for converting the reciprocating motion of the cylinder piston mechanism engine into the rotary motion comprises a crank connecting rod mechanism, an eccentric mechanism of a rotor engine, a ratchet mechanism and an overrunning clutch mechanism, but the tightness of a rotor piston of the eccentric mechanism of the rotor engine and a cylinder is difficult to solve, and the ratchet mechanism and the overrunning clutch mechanism are difficult to bear the impact of the explosion stroke of the engine, so only the crank connecting rod mechanism in the mechanisms can be really used as the mechanism for converting the reciprocating motion into the rotary motion, but the crank connecting rod mechanism belongs to a fixed stop point mechanism and cannot be used for a free piston engine. Therefore, a novel free piston engine with good continuous operation and high reliability needs to be invented.
