Definitions

  • the present invention relates to internal combustion engines primarily used in vehicles.
  • the specific feature of the internal combustion engine to which the present invention relates concerns the connecting rod which connects the piston to the crankshaft in internal combustion engines.
  • the power in the gasoline driven internal combustion engine is generated when power is transmitted to a piston contained within the cylinder of an engine.
  • the piston in turn is connected to a connecting rod which connects the piston to a crankshaft which thereafter transmits the power to the wheels of the vehicle.
  • the gasoline and air mixture enters the cylinder during the suction or intake stroke.
  • the mixture is forced into a smaller space by the rising piston.
  • the rising piston has reached its highest point, generally referred to as top dead center, the mixture has been compressed into a relatively small volume.
  • This compression of the mixture is associated with a rise in temperature which, in a spark ignition engine, must not, however, be so high as to cause spontaneous ignition.
  • the compressed mixture is ignited by a spark from the spark plug which burns in a fraction of a second , i.e. explodes.
  • the location of the connecting rod relative to the crankshaft at the time of the ignition of the gasoline is such that the angle of the connecting rod to the crankshaft generates only a small fraction of the power transmitted from the piston.
  • the Kramer Patent discloses a connecting rod of a piston machine which comprises two separate parts which are longitudinally movable relative to one another but operatively interconnected and of which one part is connected to the piston and the other part is rotatably mounted on the crank of a crankshaft, the two connecting rod parts being interconnected by a fluid spring structure in which a fluid is utilized as a spring element for operatively interconnecting the connecting rod parts.
  • the Wuerfel Patent discloses a compression spring coupling between an engine piston and the crankshaft in a four cycle, reciprocating, internal combustion engine.
  • the spring when extended to the full extent permitted, is held compressed by a force equal to the piston force required to compress the fuel mixture for proper combustion under no load or very light load.
  • the Bolen Patent discloses a connecting rod useful as a piston rod which is bifurcated into two relatively moving components which permit the rod to elongate and contract under the influence of pressure which is selectively directed into one of two variable volume part while being exhausted from the other.
  • the fluid which is directed into and exhausted out of the variable volume chambers is controlled as a function of the angular displacement of the connecting rod relative to the driving shaft.
  • the showers Patent discloses an automatically adjustable length connecting rod which is applied to each cylinder of an internal combustion engine.
  • the purpose of the adjustable length connecting rod is to substantially maintain the level of compression of the fuel mixture over a wide range of speed and torque requirements by means of varying the compression ratio.
  • Automatic adjustment and locking of the length of the connecting rod is accomplished by means of a hydraulic cylinder within the connecting rod. Pressure is applied during a suitable portion of the intake stroke to lengthen the connecting rod. Compression stroke pressure buildup overcomes a relief valve during a suitable portion of the compression stroke to adjust the length of the connecting rod.
  • the connecting rod length is hydraulically locked except during the periods of adjustment per cycle.
  • the Crise '061 Patent discloses a reciprocating piston- type internal combustion engine which is equipped with a variable length connecting rod which is operable in response to engine oil pump pressure to cause a low throttle fuel charge to be compressed in the engine cylinder to substantially the same pressure as an open throttle fuel charge.
  • An adjustable pressure regulator valve is provided to insure a substantially constant oil pressure at the connecting rod at all times during operation of the engine.
  • the Crise '002 Patent discloses a connecting rod whose length varies according to given pressure changes in the cylinder of an associated internal combustion engine.

Abstract

L'invention porte sur une bielle (10) de moteur réglable permettant au piston d'être au PMH alors que le vilebrequin ayant dépassé le PMH de trouve dans la relation angulaire la plus favorable avec la bielle pour maximiser la quantité d'énergie alternative produite dans le cylindre et la transformer en énergie rotative du vilebrequin pendant le temps moteur. L'effet optimal est obtenu par une simple circulation de liquide provenant d'une source (60) et alimentant une cellule hydraulique (62) dans laquelle il est piégé de manière à allonger automatiquement la bielle d'une certaine longueur, après quoi le liquide retourne à la source au bon moment, en harmonie avec les variations du couple et du taux de compression, tout en éliminant le cognement bien connu du moteur.
