ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to internal combustion engines, and more particularly, but not by way of limitation, to an internal combustion engine which operates on a four stroke power cycle while only rotating its power shaft one revolution as each piston goes through the four stroke power cycle.
2. Description of the Prior Art
Internal combustion engines developed in the 1800's basically are unchanged today. Existing four stroke internal combustion engines have their pistons attached to their power shaft or crank shaft in such a way that the power shaft makes two revolutions as each piston moves through the four stroke cycle.
There is a need in the prior art for improved internal combustion engine designs which are more efficient, provide longer engine life, and provide increased torque at lower operating RPM.
SUMMARY OF THE INVENTION
The present invention provides an internal combustion engine design which has a power shaft and which has at least one piston and cylinder assembly providing power to the power shaft. The engine includes a power transfer mechanism connecting the piston to the power shaft so that for each two reciprocating cycles of the piston within the cylinder, the power shaft makes only one 360° revolution or rotation.
In one embodiment, the internal combustion engine has a power shaft, a power crank, and a ratchet connecting the power crank to the power shaft. A piston is connected to the power crank by a connecting rod. An auxiliary crank shaft is provided. A two-to-one drive train connects the auxiliary crank shaft to the power shaft so that the auxiliary crank shaft rotates at twice the rotational speed of the power shaft. An auxiliary connecting rod connects the auxiliary crank shaft to the power crank so that the power crank is moved through one reciprocating cycle for each rotation of the auxiliary crank shaft.
It is therefore an object of the present invention to provide an improved internal combustion engine design.
Another object of the present invention is the provision of an internal combustion engine design which eliminates the traditional cam shaft, by combining the cam shaft and power shaft. Still another object of the present invention is the provision of an internal combustion engine design which provides longer engine life.
Yet another object of the present invention is the provision of an internal combustion engine design which results in less scoring on pistons and sleeves.
Still another object of the present invention is the provision of an internal combustion engine design which provides higher torque at lower RPM as compared to traditional engines.
Yet another object of the present invention is the provision of an internal combustion engine design having less weight in the power transmission parts between the piston and a flywheel.
Still another object of the present invention is to provide an internal combustion engine design which is economical to manufacture.
And another object of the present invention is the provision of an internal combustion engine design which is safer to operate.
These and other objects, features and advantages of the present invention will be readily apparent of those skilled in the art upon reading of the following disclosure when taken in conjunction with the accompanying drawings.
