Abstract

The motor unit consists of a flywheel (2) containing a slot (13) in which a pressure pin is able to slide under the pressure of the piston (10). A fixed arm (4) of which the base carries a shaft fixed at right angles on the motor block (1), the flywheel (2) turns freely on the right angled shaft of the fixed arm (4). The extension of the fixed arm (4) is made by a small link arm (6) pivoting on the fixed arm (4), and, at the point (9) at the link arm (8), which is subject to the movement of the piston (10). Due the force of the piston (10), the extension of the small eccentric link arm (6) transmits the force of the pressure pin sliding in the slot (13) and drives in rotation the flywheel (2).

Description

The present invention relates to an eccentric crank rod for an internal combustion engine and which can replace the conventional rod on crankshaft
The classic connecting rod on crankshaft uses its force only on a radius limited by the crankshaft crank.

The eccentric rod-nanowheel increases the power during the effort
using the principle that power increases by lengthen it
of a lever.

The extension of the eccentric crank rod in the position of-
taque increases the power exerted on a flywheel. Strength
due to the explosion being the same as in a conventional cylinder, it
AT
the result is an increase in power for the same consumption
fuel.

The accompanying drawings illustrate, by way of example only, a
embodiment of the device according to the present invention.

The eccentric crank-rod consists of an engine block (1) which carries a notorious flywheel (2). A fixed arm (4) whose base forms an integral square axis which crosses at point (5) the flywheel to be fixed behind the flywheel on the engine block (I). The steering wheel
(2) turns freely on the axis of the fixed arm (4). The fixed arm (4) carries at its upper end the foot of the small connecting rod (6) articulated at point (7). The small connecting rod (6) carries its other end the connecting rod (8) articulated at point (9) by an axis (12) protruding at the rear and penetrating into an opening (13) made in the flywheel (2) on a length required to move the axis (12). The connecting rod (8) carries the piston (10) sliding in the cylinder (11).

The operation is as follows:
The piston (10) being at top dead center in the cylinder (11), the explosion of the gases in its care does cause the conventional push to the piston (10), which in its descent pushes the connecting rod (8) which in turn by the articulation (9) causes a thrust to the axis (12), the rod end (6) rotates around the axis (7)
following the movement printed in point (9). The flywheel (2) is driven by the axis (12) which continues its thrust by sliding in the opening tl7) during the rotation of the flywheel (2). The eccentricity of the connecting rod foot (6) due to the fixed arm (4) allows the rotation of the connecting rod foot (s) around the axis (7).

In the low position of the piston (10), the small connecting rod (6) passes in front of the end of the flywheel axle) at a short distance
of this extremities The rotary power impressed on the flywheel, by its force of inertia and its complete rotation, brings the rods back to the initial position and the piston in neutral top conne in other internal combustion engines. Power is transmitted from the rear of the center of the flywheel which rotates on the axis of the fixed arm (4) and the use of power is collected at point (14).

 In the conventional crankshaft the arm (4) is articulated in the center of the flywheel and is the crank of the engine axis. By the present principle and the eccentricity of the connecting rods, the lengthening of the lever thus produced brings greater power to the rotation of the flywheel, while having only the same thrust power of the piston. The power is increased in proportion to the length of the connecting rod (6).
