Vaned petrol engine

Abstract

The invention discloses a vaned petrol engine which comprises a stator, a rotor, a vent hole, an air inlet, an electrically controlled gasoline nozzle and a spark plug. The cross section of the inner cavity of the stator is elliptic; the axes of the rotor and the stator are overlapped; the cross section of the rotor is round; at least 8 troughs are uniformly arranged on the surrounding body of the rotor along the circumference direction; vanes are arranged in the troughs; under the rotating state of the rotor, the top ends of the vanes are contacted with the inner wall of the stator; two sides of the vanes and two ends of the rotor are respectively contacted with two ends of the stator to form sealed air chambers, the number of which is equal to that of the troughs; the vent hole is arranged at the left upper area of the stator; the air inlet is arranged at the right upper area of the stator; moreover, the electrically controlled gasoline nozzle and the spark plug are arranged at the left lower area of the stator. The vaned petrol engine can reduce the size of the rotor, is convenient to replace the vanes, reduces the production and running cost, runs smoothly, is hard to damage spare parts, has long service life, improves the thermo-motive efficiency, and can be manufactured into a high-power engine.

Description

technical field [0001] The invention relates to an internal combustion engine, in particular to a vane 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 replace the p...

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.
