Ellipse-like rotor engine with high sealing performance

Abstract

The invention discloses an ellipse-like rotor engine with high sealing performance. The engine comprises an upper end cover, a lower end cover, a rotor, three combustion cavities, three sections of isolation belts, an oil injection ignition device, sealing pin rows and an eccentric driving shaft. According to the technical scheme, a new design scheme is provided for molded lines of the rotor and acylinder body, on the basis, the sealing pin rows are introduced to seal transition areas among the different combustion cavities, the engine can well prevent the structure abrasion effect, the sealing performance among the combustion cavities is effectively enhanced, gas leakage among cylinder bodies is reduced, and the designed molded lines and sealing mode can increase the design error marginof the engine and reduce the machining difficulty of the engine, so that the production cost of the engine is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of engines, and in particular relates to a quasi-elliptic rotor engine with improved sealing performance. Background technique [0002] The rotary engine is a novel internal combustion engine that appeared in the 1950s. Compared with the general reciprocating piston internal combustion engine, the rotary engine has the advantages of small size, high power-to-weight ratio, and low vibration and noise. Among them, the triangular rotor engine is a more commonly used scheme. This engine is also called Wankel engine. The meshing drives the rotor to do planetary motion around the cylinder, which is a four-stroke engine. [0003] In order to ensure the tightness of the engine during operation, the three protruding points on the triangular rotor of the traditional triangular rotor engine will always rotate at a high speed in a state of keeping close to the cylinder wall. As the service time prolongs, the sealing p...

AI Technical Summary

Problems solved by technology

The X engine redesigned the rotor profile and cylinder profile of the rotary engine from the perspective of internal and external adjustment. However, this plan only exchanged the internal and external order of the rotor profile and cylinder profile, but failed to change the structure and shape of the profile itself. sports characteristics

Therefore, this solution still has problems such as severe seal wear, cylinder gas leakage, and high processing costs.
