Multi-cylinder rotor engine

Abstract

The invention provides a multi-cylinder rotor engine. The multi-cylinder rotor engine comprises a first cylinder body and a second cylinder body. Multiple combustion chambers are formed by the wall face of the second cylinder body and a second rotor. Fuel gas is compressed and conveyed into any combustion chamber of the second cylinder body for acting from the interior of the first cylinder body through an eccentric mechanism. The rotor in the second cylinder body and the eccentric mechanism rotate coaxially. The second cylinder body is a round cylinder body, the second rotor and the second cylinder body are mounted coaxially, and the volumes of the multiple combustion chambers are kept unchanged in the rotating process of the second rotor. The second rotor is a regular polygon or looks like the regular polygon. In the second rotor looking like the regular polygon, the sides of the regular polygon are inwards-bent arcs, and one arc-shaped combustion chamber is formed by any inwards-bent arc and the wall face of the second cylinder body. The multi-cylinder rotor engine is a novel rotor engine in which inlet gas compression and combustion exhaust processes are carried out in the different cylinder bodies, and therefore the performance of the rotor engine is improved.

Description

technical field [0001] The invention relates to the technical field of rotary engines, in particular to a multi-cylinder rotary engine. Background technique [0002] The rotary engine is another high-efficiency power machine besides the traditional reciprocating engine. It is widely used in many civil and military fields due to its simple structure, fewer parts, and stable operation. Especially in recent years, the rapid development of electric vehicles and small unmanned aerial vehicles has brought new opportunities to the development of rotary engines, because the range extender and small unmanned aerial vehicles, which are the core components of extended-range electric vehicles, are in urgent need of a A power plant with compact structure and high power-to-weight ratio, and the unique advantages of the rotary engine make it just meet the requirements of this pair of power plants. However, the precise machining and combustion efficiency of each component of the rotary eng...

AI Technical Summary

Problems solved by technology

[0006] (3) Due to the narrow and long combustion chamber of the rotary engine, the speed of flame spread is slow, resulting in insufficient fuel combustion, which restricts the efficiency of the rotary engine and increases the emission of harmful gases

[0007] (4) Due to the triangular rotor design of the Wankel rotary engine, the rotor performs three times of fixed work every time it rotates and cannot be changed.
