  • Patent number: 5682853
    Abstract: The present invention relates to a unique piston and rod assembly which easily replaces an existing prior art piston and rod assembly, as found within any typical internal combustion engine. The present invention teaches a unique design which incorporates therein, a rack and pinion as the means to moveably attach the top end of the rod to the piston with a slider mechanism to keep the rack and pinion in close tolerance with each other. The horizontal travel of the crank shaft and the rod journal cause a rocking motion at the junction of the rod and piston, which causes the piston to rise and fall after top-dead-center (T.D.C.), and after bottom-dead-center (B.D.C.), thus producing numerous advantages, including less emissions, less fuel consumption, greater power, greater torque, etc.
