AI Technical Summary

Technical Problem

Existing reciprocating internal combustion engines and Wankel rotary engines suffer from problems such as high mechanical energy loss, large frictional resistance, serious gas leakage, severe thermal deformation, and limited fuel compatibility, and it is difficult to optimize energy efficiency and operating costs.

Method used

It adopts a disc rotor structure, with a small gap precision fit only in the working area. It uses the pressure difference between the inside and outside of the cylinder to form a pneumatic self-sealing, eliminating the inertial force of reciprocating motion. The working surface of the rotor is arranged along the whole circumference, eliminating the ignition timing control system and making it compatible with multiple fuels.

Benefits of technology

It improves energy efficiency, reduces friction loss and gas leakage, extends component life, simplifies structure, expands the range of applicable fuels, and enhances adaptability to operating conditions.

Abstract

The application discloses a disc rotor chord impact engine, comprising a body, a disc rotor, a transmission shaft, a working cylinder, a fuel supply mechanism and an ignition mechanism. The outer periphery of the rotor is provided with a circumferential force receiving surface, which cooperates with the working cylinder to form a working unit; the working area is matched with a small gap, and relies on the pressure difference between the inside and outside of the cylinder to form a pneumatic self-sealing, and the remaining area is reserved with a gap to reduce friction. The fuel is injected into the cylinder at high pressure and ignited to burn, and the gas expansion drives the rotor to rotate, and after the rotor rotates out of the cylinder, the exhaust gas is discharged by inertia, and at the same time, double cooling is realized by means of the exhaust gas and the normal temperature environment. The working surface is arranged along the circumference of the rotor, and a continuous tooth structure can be selected according to requirements, and the force at any rotation position can be realized, and the ignition timing structure and the auxiliary starting mechanism can be cancelled; the application is suitable for various combustible gases and combustible oil gas mixtures, and the power can be adjusted according to the working condition requirements, and has the advantages of simple structure, high energy utilization rate, convenient starting, stable operation, and wide application scenarios.
