[0002] The reciprocating speed of the existing conventional internal combustion engine piston is limited by unfavorable factors such as the thermal load of the piston group, the unbalanced inertial force of the crank connecting rod mechanism, the linear speed of the crank pin, the roll friction force, and the friction caused by the roll friction force. The increase of speed will increase the above unfavorable factors, the working environment of the piston will deteriorate, the wear will increase, and the service life will decrease. Generally, the allowable speed does not exceed 15m / s

[0003] The invention patent previously applied by the applicant "Application No. 200710193939.4 A Piston Reciprocating Internal Combustion Engine and Its Combination and Cylinder Deactivation Technology" discloses a new type of piston reciprocating internal combustion engine, which is disclosed in the invention patent "Application No. 200710147446.7 A Rack and Pinion Mechanism" The first rack and pinion mechanism is used as the power mechanism of the engine, which solves the hazards of the conventional internal combustion engine crank-link mechanism inertial force and high crank pin linear velocity. The engine cylinder piston reciprocates 3 times up and down, which is 3 times that of the engine cylinder piston reciprocating 1 time when the crankshaft connecting rod mechanism rotates once. Therefore, the power of the engine can be increased to 3 times of the power of the existing conventional internal combustion engine; however, the average speed of the engine cylinder piston reciprocating should also be correspondingly the maximum allowable value of the existing piston reciprocating average speed 3 times, otherwise, the "rack and pinion mechanism" will not be able to exert the effect of strengthening the engine power

[0004] In the "A Piston Reciprocating Internal Combustion Engine" disclosed in the invention application "200710193939.4", the designed system positioning technical means ( image 3 shown on the right), it cannot overcome the damage of the system roll force and reduce the friction between the piston and the inner wall of the engine cylinder, and the piston is not easy to dissipate heat, and there are also defects that are difficult to detect and repair due to large wear

Although the "rack and pinion mechanism" is used as the power mechanism to overcome the disadvantages of the unbalanced inertia force of the existing conventional internal combustion engine and the high crank pin line speed, the unfavorable factors of increasing the reciprocating speed of the piston, but the heat load of the engine cylinder piston group and the system roll force are harmful. disadvantages still exist
