Description

ENGINE "BUCHERONS" WITH FIXED OSCILLATING ROD

The purpose of this invention is the creation of a new generation of engines whose transformation of the combustion energy in rotary motion will no longer be done by the interposition of connecting rods between the pistons and the crankshaft as it is in use currently. The transfer of movement between the pistons and the crankshaft will now be by a substitution mechanism which is the substance of the invention.

It also aims to introduce a new architectural form in order to increase its efficiency, reduce the number of its components and especially its volume and weight. It can be in two, four or eight cylinders.

The originality of the invention being the transformation of the reciprocating piston movement in rotary movement of the crankshaft to a single crankpin through a fixed connecting rod (mechanism) to the axes of the pistons and connected to the crankshaft. It also covers:

1. The horizontal arrangement of pairs of pistons facing each other in the form of "loggers";

2. removal of traditional rods which are the main cause of piston wear by scrubbing and other breakage of the segments;

3. removal of the timing chain and its replacement by direct transmission, by interposed gear wheels, movements to cams and pushers;

4. replacement of the crankshaft with multiple pedals and pedals by a single pedal (crankpin) and the incorporation of a single rod with alternating rectilinear translation (mechanism);

5. removal and replacement of the water cooling system;

6. adaptability to all uses and all types of vehicles;

7. space and space savings because an engine with a cylindrical volume of 1.5 liters will have a maximum dimension of: L = 62; 1 = 14; h = 26 cm; 8. Lower center of gravity to a level never equaled.

PRIOR TECHNIQUES

Despite significant advances in research for improving yields and refining the various settings, the general form, principle and operating rules of the combustion / combustion engine have remained the same since their invention. They continue to equip almost all vehicles and machines around the world. The multiplication of the valves, the increase of the number of pistons and / or their volumes did not bring the solution to the recurring shapes of cylinder in line in star or in V. Our current knowledge shows that apart from the engine with reactors, the traditional engine explosion / combustion keeps, essentially, the same principle of operation namely: the four engine time times that are Admission, Compression, Explosion and Exhaust; converting the reciprocating translation movement of the pistons into circular motion by rods and crankshaft with bearings and pedals; the transmission of this same movement to the camshaft by the timing chain which actuates in turn the rocker fingers which control the opening and closing of the valves.

This device requires the existence of an engine block, sometimes two blocks for some others, one or more distribution chains, an imposing cylinder head, mechanisms and other gears necessary for their implementation. Concomitant with this, we will note the importance of consumption due in particular to the overall volume of the engine, the resistance due to friction and the drive of the various bodies and other couplers.

PRESENTATION OF THE INVENTION

The shape of the motor shown in Figure 1 is first of all an innovation in itself because it relates to a new arrangement of horizontal cylinders in the form of pairs face to face in the position of "loggers". The movement and the mutual training of the pistons is realized by a harmonious sequence between the reciprocating pistons movements which print its continuous movement to the crankshaft with a single pedal by a rod (mechanism) with right movement provided with a vertical notch in which is moves the crankpin crankpin.

The transfer of the movement and the control of the valves and their adjustment, for simultaneous obtaining, four times of the pistons and the rotation of the new crankshaft; because this mechanism makes it possible, thanks to the difference of the diameters of the gears, to produce the four-piston engine time effect.

This step makes it possible to obtain an explosion phase at each half-turn of the crankshaft and permanently, thus a constant pressure on the crankshaft without having the need to fill the absence of pressure by resorting to a greater force of inertia. or additional cylinders to maintain the cadence and linearity of movement. We will also notice that the equidistance of the cylinders on the one hand and their arrangement face to face, for the engines with four and eight cylinders, on the same plane on the other hand, make easy the faculty of a staggered distribution of the effort at the time of the explosion (relaxation).

It is to the exorbitant excesses of materials and organs - which sometimes absorb up to thirty percent of the energy consumed - that my invention came to bring order and simplify as much as possible the functionality and profitability of the new engine .

The lightening of the engine object of this invention is due essentially to its new architecture which makes it compact, simple and a number of components reduced by more than half.

Reduction of fuel consumption: The reduction of fuel consumption is essentially achieved by the elimination of the resistances due to the multiplication of the organs and the drawn couplings and their friction.

Increase of the service life: The wear of the vital organs of the motor is due mainly to the friction, torsions and bends, the reduction of a good part of the bodies in contact and the elimination of the twists and bends in particular at the levels connecting rods significantly increase the life of the new engine.

Deletion and replacement of the water cooling system: The multiplicity of highly congested components subject to frequent damage and premature wear such as radiators, hoses, water pumps and their corollary, the approximate monitoring system of the temperature, are the cause

Main if not in significant proportions of breakdowns and other fixed assets of the engine.

To remedy this situation in the new engine, only the current oil pump is renewed with an additional function, in addition to the lubrication, that of sucking the oil stored in the receiver (casing) by flow gravitational, to push back to the cooler (natural or in the form of a serpentine contained in a ventilated hose) before reinjecting it into the irrigation and cooling network of the engine.
