Cam mechanism inside internal combustion engine with piston doing circular motion

Abstract

The invention relates to an internal combustion engine, a gasoline engine and a natural gas engine, in particular to a cam mechanism of an internal combustion engine with piston doing circular motion. In the prior art, internal combustion engines with piston doing linear motion have defects of small working stroke of pistons and energy waste, and traditional rotator internal combustion engines consume part of power to push rotational moving structures of rotators, which causes energy waste. The invention aims to provide the cam mechanism inside the internal combustion engine with piston doing circular motion. The cam mechanism comprises a timing gear member and a camshaft member, wherein the timing gear member is formed through fixing a timing gear and a conical timing gear on a timing gear shaft, and a shell is formed through connecting an outer cylinder shell and an outer shell of the internal combustion engine. The invention changes the linear motion of pistons into the curvilinear motion of pistons in the traditional internal combustion engines with piston doing linear motion, thereby increasing the working stroke, increasing the working efficiency, eliminating the energy waste, and thoroughly solving problems in the prior art.

1. Technical field [0001] The invention relates to an internal combustion engine, a gasoline engine and a natural gas engine, in particular to a cam mechanism in a piston circular motion internal combustion engine. 2. Technical Background [0002] In the prior art, comparatively mature piston reciprocating internal combustion engines and rotor internal combustion engines are generally used, and its existing engines have congenital defects: 1. The piston of the existing piston linear motion internal combustion engine is a linear reciprocating motion up and down, and the piston The working stroke of the air compressor is small, and the energy generated by the expansion gas is discharged without full (work) utilization, resulting in waste. Simultaneously, the connecting rod and the crank of the piston up and down linear reciprocating internal combustion engine do not transmit the thrust generated by the expansion gas to the piston, so that the thrust is accurately and completel...

AI Technical Summary

Problems solved by technology

[0002] In the prior art, comparatively mature piston reciprocating internal combustion engines and rotor internal combustion engines are generally used, and its existing engines have congenital defects: 1. The piston of the existing piston linear motion internal combustion engine is a linear reciprocating motion up and down, and the piston The working stroke is small, and the energy generated by the expansion gas is discharged without full (work) utilization, resulting in waste

In the process of converting the chemical energy of the fuel into mechanical energy in the piston up and down linear reciprocating internal combustion engine, the energy is wasted needlessly due to the compression of the gas.

2. The work of existing rotor-type internal combustion engines is to push the rotor to do directional rotation by the directional combined external force produced by the end of the combustion chamber with relatively large volume and relatively strong force overcoming the end of the combustion chamber with relatively small volume and relatively weak force, or in other words: Output work = big end work - small end work, this kind of structure that consumes part of the work to push the rotor to rotate causes waste of work energy

Its disadvantages are complex structure, energy consumption of compressed mixed gas, low work efficiency, etc.
