Description
Technical Field
The application relates to the technical field of mechanical power, in particular to a circumferential rotor engine.
Background
Currently, there are two main types of engines.
Firstly, a reciprocating piston engine does reciprocating linear motion in a cylinder during working and can not directly output power, so that the linear motion of a piston is required to be converted into circular motion, and a crank-link mechanism is required to indirectly output circular motion power;
meanwhile, the crank-link mechanism can be regarded as lever movement, the input power is unchanged, the length of the lever is set as a power arm L, the power applied to the power arm by the actual power is dynamically changed, namely, the input power is not perpendicular to the power arm and is changed at regular angles, and the force (tangential direction) actually applied to the power arm is presented: from small to large, calculating 50% of power loss through a series from the change trend from large to small;
according to the power p=fv=f (C/T), the same perimeter motion is equal for the same time, the linear velocity is equal, and the output power fsmeans is lost by 50%, i.e. the mechanical efficiency is lost by 50%. It is also known that the thermal efficiency of the engine does not substantially exceed 50%. Therefore, the reciprocating piston engine must use a crank-link mechanism to indirectly output circular motion power, and the power conversion process has power loss (doing negative work), so the design is not energy-saving.
Secondly, the rotor engine, on one hand, has the working principle that the eccentric rotary motion is then directly transmitted to the output shaft through the rotary power to do circular motion, and the circular motion power is also indirectly output; on the other hand, the pressure bearing surfaces of the piston in the cylinder are actually 2, one power front-end surface and the other power rear-end surface, the power rear-end surface is smaller than the power front-end surface, and the pressure bearing surfaces of the power rear-end surfaces can offset part of forward power, so that the mechanical efficiency of the engine is reduced. Therefore, the design is also not energy efficient.
Both of the above engines have a large duty cycle of power loss due to design.
