Gasoline engine with eccentric rotor

Abstract

The invention discloses a gasoline engine with an eccentric rotor, which comprises a stator of which the inner cavity cross section is circular, a rotor with a circular cross section, an air inlet hole, an air vent hole, an electronic control gasoline nozzle and a spark plug, wherein the distance formed by deviating the axle center of the rotor from the axle center of the stator leftwards along the horizontal direction is e; at least eight uniformly-distributed grooves are formed on the circumferential body of the rotor; each groove is provided with an oblong blade; in the state that the rotor rotates along the clockwise direction, the top of the blade is contacted with the inner wall of the stator under the action of centrifugal force; the two sides of the blade and the two ends of the rotor are contacted with the two ends of the stator respectively to form sealed air chambers of which the number is equal to that of the grooves; the air vent hole and the air inlet hole are formed on an end cover in the inclined left area below the inner cavity of the stator and an end cover in the inclined left area above the inner cavity of the stator respectively; and the electronic control gasoline nozzle and the spark plug are positioned on an end cover in the left area below the inner cavity of the stator. Compared with the prior art, the engine has high thermodynamic efficiency, low production cost, a simple structure and long service life.

Description

technical field [0001] The invention relates to an internal combustion engine, in particular to an eccentric rotor gasoline engine. Background technique [0002] In the traditional piston gasoline engine, the piston reciprocates in the cylinder and needs to be continuously accelerated and decelerated. This structure not only affects its work efficiency, but also has a large vibration. [0003] At present, a new type of triangular rotor engine appears. Like the piston engine, the triangular rotor engine also uses the pressure generated by the combustion of air and fuel mixture. The difference is that in a piston engine, the pressure generated by combustion is stored in the cylinder, driving the piston, and the connecting rod and crankshaft convert the reciprocating motion of the piston into rotary motion, while in the rotary engine, the pressure generated by combustion is stored in the stator In the sealed chamber formed by the inner wall and the triangular rotor (used to r...

AI Technical Summary

Problems solved by technology

However, the structure still has the following defects: first, the thermodynamic efficiency is low, and compared with the piston engine, the compression ratio of the combustion chamber is lower, so it consumes more fuel than the piston engine, and cannot be used as a high-power engine; The production cost is high, and the structure of the triangular rotor is relatively complicated, which is not easy to process and assemble

It is precisely because of these defects that the triangular rotor engine has not been widely used so far.
