A rotary engine and its working method

Abstract

The invention relates to the field of internal combustion engines, in particular to a rotor engine and a working method thereof. The rotor engine comprises at least one set of power modules for outputting power; the power modules include shells, end covers, two cylinder covers mounted on the shells, and N rotor units; the two cylinder covers are distributed in the upper and lower positions of the shells in a center symmetry manner; the N rotor units are arranged in the shells in sequence front and back; separation plates are arranged between the adjacent rotor units, and are provided with multiple air crossing small holes for ventilation among the rotor units; and N is a natural number not smaller than 2.

Description

technical field [0001] The invention relates to the field of internal combustion engines, in particular to a rotary engine and a working method thereof. Background technique [0002] In the prior art, engines mainly include reciprocating engines and rotary engines, both of which rely on the expansion pressure generated by the combustion of air-fuel mixture to obtain rotational force. [0003] like figure 1 As shown, the four-stroke reciprocating engine requires the piston to reciprocate in the cylinder, and the crankshaft is driven by the crank-link mechanism. The disadvantage of this method is that the connecting parts of the mechanical parts are subjected to a large impact load, and the mechanical noise generated is large. The mechanical strength, machining accuracy and lubrication requirements are all high. [0004] like figure 2 As shown, the rotary engine is mainly the triangular rotary engine of Mazda Company. This engine directly pushes the pressure generated by t...

Problems solved by technology

The disadvantages of existing rotary engines are: the combustion time is short and the combustion is incomplete; the lubrication method is splash lubrication, the oil consumption is large, and the oil is discharged with the exhaust gas, and the emission exceeds the standard

[0005] When natural gas is used as fuel, both engines have the following disadvantages: 1) The combustion time is short, resulting in fuel after-combustion, which cannot effectively perform work; 2) The exhaust temperature is high, resulting in low thermal efficiency of the engine; 3) It is prone to knocking, which seriously affect machine work
