Definitions

• the object of the present invention is to show how these defects can be corrected, again using strictly conventional connecting rods. More specifically, the applicant proposes to use for each engine cylinder, a polymaneton crankshaft, each crank pin being connected to a connecting rod or to a pair of connecting rods, these connecting rods being in turn connected, for one to the upper piston inserted in the main cylinder and for the other the lower piston inserted in the cylinder arranged in the upper piston itself FIG. III. Of course, for reasons of balance of the parts, the upper piston may be supported by a set of two lateral connecting rods.
• crankpins Two main configurations are possible, starting from the above-described arrangement of the parts, depending on whether the lower and upper crankpins are arranged in the opposite parts of the same axis, or even in the same part. In the two aforementioned cases, the crankpins must be of different radius, otherwise the desired effects would obviously be canceled.
• crankpins in a first case FIG. III, by placing the crankpins in the parts of the same axis, it will be possible to produce a two-stroke engine, strictly with gas, and driven by conventional connecting rods. Indeed, by connecting to the so-called upper crankpin, two upper connecting rods connecting it to the upper piston, we will then insert the piston into the main cylinder.
• each piston will occupy the opposite situation of its complementary piston, at the same time.
• the upper piston when the upper piston is in its highest phase, the lower piston will be in its lowest phase.
• the upper piston will be in its lowest phase, the lower piston will be in its highest phase, and so on, successively.
• the arrangement of the upper and lower crankpins must be designed differently. Indeed, although by placing them, as previously, at different radii, it will not only be necessary to have them on the same axis, but moreover, in the same dial.
• the purpose of this arrangement is to simultaneously force the opening and closing of the main cylinder and the intake of the burnt gases, so that the maximum suction of the lower cylinder corresponds to the end of the expansion of the burnt gases.
• two crankpins of different spokes will be placed on the crankshaft, per cylinder. These two crankpins, in addition to being arranged on the same axis, will be on the same dial.
• a connecting rod or a set of upper connecting rods which themselves will be attached to a so-called upper piston.
• This piston will be inserted in the main cylinder, itself provided, in its lower part, with a cylinder which will be called lower cylinder.
• a second connecting rod will be connected to the lower crankpin and at its opposite end to a lower piston.
• This piston will be slidably inserted into the cylinder integrated in the lower part of the lower piston.
• the pistons will have similar stroke moments, but, taking into account the different radii of the crankpins, different in height, there will be, although with the same direction races, limit points of different heights: In other words, the upper and lower pistons will be simultaneously at their highest level and simultaneously at their lowest level.
• the two phases of the backflow prevention motors can therefore be carried out here. Indeed, when the two pistons are at their lowest level, the suction caused in the lower cylinder will suck the burnt gases and new gases will enter the main cylinder, consequently. In the following time, while the two pistons are at their maximum ascent in the cylinder, the explosion can occur in the main cylinder and the complete and filterable exhaust in the lower cylinder.

• Figure I is a reproduction of one of the embodiments of the applicant's invention entitled "Poly-induction energy engine”.
• Figure II is a reproduction of Figure IV of the applicant's invention entitled "Anti-backflow energy engine”. Again, after isolating the bottom from the cylinder of the engine body, it is possible to produce the suction of the burnt gases in this chamber, thereby sucking in new new gases in the main combustion chamber. In this way, a two-stroke engine can be produced which will be fully filterable.
• Figure III shows a cross section of the two main moments (a) and (b) of an engine embodying the present invention.
• a crankshaft 5 in the body of an engine is inserted one or more cylinders 11, as is rotatably mounted a crankshaft 5.
• This crankshaft has the distinction, for each cylinder, to have two crankpins, whose radii are not identical and which will be called upper crankpin 6 and lower crankpin 7.
• upper crankpin 6 and lower crankpin 7. In the case of the upper crankpin and in order to ensure a balance in the support of the upper piston, it will be preferable to split 8 the connecting rods.
• Each crankpin will be connected to a connecting rod, or to a set of connecting rods, connected or connected to a piston.
• the upper connecting rods 9 will be connected to the upper piston 10.
• the latter will be slidably inserted into the main cylinder 11, and will furthermore be provided in its lower part with a cylinder 12, capable of slidingly receiving the lower piston. 13.
• the lower piston will be connected to the lower link 14 and at its second end to the lower piston. This piston will indeed be slidably inserted into the cylinder of the upper piston 12.

• one or more cylinders 11 are rigidly inserted into the block of an engine, as is, rotatively, a crankshaft 5.
• This crankshaft has the particularity, for each cylinder of having two crankpins whose radii are different and which will be called upper crankpin 6 and lower crankpin 7, depending on whether they are attached to the upper piston or to the lower piston.
• Each crankpin is connected to a connecting rod 9 or to a set of connecting rods 14, themselves connected to an upper piston and to a lower piston.
• the upper piston 10 is slidably inserted into the main cylinder 11, while the lower piston will be inserted into the cylinder of the main piston 12.
• the lower and upper crankpins which, as previously are not of the same radius, will not only be located on the same axis, but also in the same dial.
• This arrangement will completely reverse the action of the pistons between them.
• the pistons will work in the same direction, which will have the result that they will be at the same time in their upper phase 21 and in their lower phase 22.
• the lower piston can, at its lowest level, suck the burnt gases 23, thus sucking the new gases in the upper cylinder, in the following time, the gases will be simultaneously exploded and evacuated 24 by one and the other of the chambers.
• Figure VI is a three-dimensional view of the previous embodiment.
• the exhaust pipes and valves 25, the burnt gas intake 26 and fresh gas intake 27 pipes, have been added.
