Definitions

  • the present invention refers to an internal com­bustion motor, concretely a reciprocating motor, of the type of those in which the combustible ignition or explo­sion inside of two or several cylinders chambers determi­nes the displacement of corresponding pistons which suffer that way a reciprocative motion converted into a gyratory movement for a crankshaft through the corresponding arms.
  • the object of the invention is centered over a structuralization special for this type of motor which fa­cilitates the dimensioning and placement of the inlet and outlet valves at the same time that balances the forces distribution in the motor minimizing the variations.
  • the internal combustion mo­tors, reciprocating, as well in the case of explosion mo­tors as in that of combustion motors have as fundamental function to supply, generally to several chambers or cylinders, a mixture of combustible air, to press inmediately afterwards such mixture until producing an automatic ignition or until a certain point when an electric spark jumps inside the chamber by mean of a spark plug forcing the piston to a quick longitudinal displacement which is what is used as propulsive energy, finally producing the bump out of gases resulting from the combustion.
  • the intake and exhaust phases mean a respective loss of energy owing to the fact that when intaking the piston actuates as suction pump getting its energy from the crankshaft and, as a consequence, takes away energy fro the piston which in that moment is in the phase of ex­plosion, at the same time that, during the exhausting pha­se, the piston acts as forcing pump also taking its energy from the crankshaft.
  • these losses of energy will be as small as bigger are the intake and exhausting valves, but such dimensions are substantially limited by the cylin­der's own volumetry and by the need of establishing in the­se cylinders other accessories, such as spark plugs or in­jectors.
  • the internal combustion motor proposed by the in­vention has been conceived and structurated to solve at full satisfaction above problematic, in the two slopes pre­viously cited, allowing, from one side, a major dimentio­ning and easier placement for the intake valve and for the exhaust valve as well, securing, at the same time a more balanced functioning of the motor, from the view point of forces distribution.
  • the said motor center its characteristics in the fact that, in replacement of each operative group unitary and conventio­nal integrated by a cylinder, a piston an arm directly con­nected to the crankshaft, the corresponding couple of in­take and exhausting valves and all other accessories such as spark plug or injector incorporates two cylinders dully inter-connected between themselves to form a unique chamber from the functional or operative viewpoint, being those two pistons related through the corresponding arms with the respective crankshafts which are, at their time inter­related to obtain a perfectly synchronized movement that is transmitted to an unique exit axle which can be one of its own crankshafts.
  • each chamber or u­nitary operative group materializes in two cylinders (9-9′) in which act two pistons (10-10′) linked articulately to the corresponding arms (11-11′), being, obviously, related both cylinders (9-9′) between themselves by mean of a co­mmunicating pass (12), to really configurate a chamber or unique operative group, a communicating pass (12) where will be put, preferently, the spark plug or injector so that this last element do not obstruct the placing of the intake and exhaust valves (3-4), so that above element is in the more suitable position for those valves.
  • the arms (11-1′) are fitted on the respective crankshafts (13-12′), which is to say, that the motor in­corporates two crankshafts parallels in front of the unique crankshaft of conventional alternative motors and each pair of arms (11-11′) corresponding to the same operative group will be related between themselves through toothed sectors (14-14′) who put itselves in gear permanently and secure a perfect synchronism in the lineal shifting of the pistons corresponding (10-10′) or, which is the same, a perfect sychronism between the two crankshafts (13-13′) which, through any conventional mean provide the movement to an unique axle of exit.
  • the materials, shape, size and set up of the ele­ments can be variated, if and when, that do not mean any change to the invention in its essence.
