Rotary engine of oval cylinder

Abstract

The invention relates to an engine, in particular to a rotary engine of an oval cylinder. The rotary engine comprises a principal axis, a bulged triangular rotor, a cylinder, an air inlet, an air outlet; wherein the inner surface of the cylinder is oval, central 01 point of the bulged triangular rotor moves circularly around the central point O of the cylinder, the cambered surface trail of two random apexes of the three apexes of the bulged rotor is planet trail, an elastic seal door is arranged at the tangency point between the cylinder and the bulged triangular rotor and the elastic seal door is arranged on the cylinder. The invention has the following beneficial effects: in the sparking moment, the elastic seal door at K point prevents gasoline doing negative work in the second half of a chamber from being ignited and discharging the gasoline to a chamber through a blind pass to be recompressed, thus saving gasoline, increasing torque of useful work and solving the problem of oil leakage and poor pollution discharge. Therefore, use cost is reduced and service life is lengthened.

Description

technical field [0001] The invention relates to an engine, in particular to a rotary engine with an oval cylinder. Background technique [0002] At present, the engine is divided into two types, one is a piston reciprocating engine, and the other is a rotary engine. Among them, the piston reciprocating engine has low effective thermal efficiency, while the rotary engine represents a convex triangular rotor engine. Its shape is a convex triangular rotor. There are three radial small elastic sealing pieces, two arc-shaped lateral sealing strips and wave springs are arranged on both sides of the rotor, and six arc-shaped lateral sealing strips and wave springs are arranged on three sides. The three small elastic seals installed on the three vertices of the triangular rotor are in line contact with the surface of the cylinder block, like three sharp knives scraping each other on the surface of the hard chrome plated surface, and the friction will be quickly on the surface. The...

AI Technical Summary

Problems solved by technology

The three small elastic seals installed on the three vertices of the triangular rotor are in line contact with the surface of the cylinder body, like three sharp knives scraping each other on the surface of the hard chrome plated surface, and the surface will quickly There will be wavy vibration wear, so the engine wears seriously and has a short life.

Due to the above reasons, rotary engines are generally used in racing cars and cannot be widely used.
