Background
The most common engines in daily life are reciprocating piston engines; there are also less common wankel rotary piston engines. The reciprocating piston engine is characterized in that the reciprocating linear motion of a piston is changed into the axial center circular rotation of a power output main shaft through a crankshaft, and the reciprocating piston engine also has the defect that the end piston reciprocating in a cylinder has zero motion speed, and energy is additionally consumed when the piston is accelerated from zero every time. Taking a four-stroke reciprocating piston engine as an example, it does not perform work even with one intake stroke, but the piston and associated components are operated once, which consumes energy. The Wankel rotary piston engine features that when the rotor does work, its center rotates around a shaft which is not concentric and drives the shaft to rotate, and at the same time, it also rotates. It has the disadvantages that the friction between the rotor and the cylinder wall and the friction between the gear of the rotor and the gear of the cylinder body during the rotation around the shaft are also generated; the shape of the combustion chamber is not ideal, and the combustion chamber is slender and unfavorable for combustion during ignition, so that the oil consumption is high, and the emission is not easy to reach the standard; the contact friction between the end of the rotor and the cylinder wall is severe when the rotor rotates at high speed; the planar shape of the cylinder is determined by the motion track of the rotor, so that the compression ratio of the cylinder cannot be changed, and the difficulty is increased for using the high-compression-ratio combustion technology developed in recent years.
