A Pendulum Block Matching Cam Rotor Internal Combustion Engine Power System

Abstract

The invention relates to a swinging block and cam rotor cooperating internal combustion engine power system and belongs to the field of internal combustion engines. In the power system, cam rotors and a plurality of swinging driven parts are adopted to form a cam mechanism, the cam rotors, the swinging driven parts, rotor chambers and end members form a plurality of circumferentially distributed sealed working chambers; the volumes of the sealed working chambers are changed along with rotation of the cam rotors, and the four processes of air inflowing, compression, acting and exhausting of an otto cycle are finished in the working chambers through cooperation with air valves; and chemical energy generated by gas combustion is directly converted into fixed-shaft rotation type mechanical energy of the rotors. According to the swinging block and cam rotor cooperating internal combustion engine power system, planetary motion of Wankel rotors and an inner chamber in a specific shape are not needed, high-pressure gas directly pushes the rotors to perform fixed-shaft rotation and power is output, the structure is simple, and the parameter adjustable range is wide. Flexible control is easy to achieve under control of an added swinging block escapement device, and compared with piston internal combustion engine and Wankel rotor internal combustion engine power systems, the swinging block and cam rotor cooperating internal combustion engine power system has much more outstanding advantages.

Description

technical field [0001] The invention belongs to the field of internal combustion engines, and relates to a pendulum block matching cam rotor internal combustion engine power system. Background technique [0002] The piston internal combustion engine is the earliest internal combustion engine that came out. Its characteristic is that the piston makes a reciprocating linear motion in the cylinder, and the output of the crankshaft rotary motion is realized through the crank slider mechanism. Within two weeks of crankshaft rotation, the cylinder completes a complete intake, compression, work, and exhaust four working processes, that is, the Otto cycle. It is generally believed that the piston internal combustion engine has the advantages of high thermal efficiency, compact structure, strong maneuverability, and easy operation and maintenance. It is even believed that the power device of the piston internal combustion engine, especially the mechanical structure, has reached the ...

AI Technical Summary

Problems solved by technology

However, there are still key problems such as high processing requirements for core parts, too sensitive to wear, difficult adjustment of compression ratio, low thermal efficiency, etc., and it is still difficult to improve the combustion utilization rate

At the same time, similar to the piston internal combustion engine, the scalability of the triangular rotor internal combustion engine structure is also limited

In addition, when the expansion force generated by the fuel is converted into the power of the output shaft, there are natural defects in the transmission of force

Although the expansion force can push the rotor to rotate, it is difficult to increase the torque of the resultant force on the rotor shaft, and the proportion of internal friction is also too high
