Definitions

  • the invention pertains to improvements of internal combustion engines whether with a reciprocating or rotary or orbital piston at which is solved more complete displacement of combustion gases from the cylinder before a fuel-air mixture is sucked or filled in.
  • Disposition of the hitherto known internal combustion engines enables displacement of such quantum of combustion gases which by own cubic capacity equals to exhaustion stroke of the piston. This is because the exhaustion stroke equals to the compressive one that is why after exhaustion stroke always remains just such quantum of combustion gases which by own undiluted volume equal to cubic volume which is necessary for compression of the fuel-air mixture in the cylinder.
  • the defect consist in that the fuel-air mixture is always sucked or filled up to a remainder of combustion gases into the cylinder which substantially depreciates so ready fual-air mixture to campression and it does not only make perceptible aggravation for ignition or ignition by compression but it especially reduces effect of expansion, alias it reduces efficiency of the internal combustion engines.
  • Basic principles of the invention are equipment of a piston assembly by a resilient mounting; disposition of the cylinder and of the piston which are made so that they enable to reduce the exhausting space to the pr oject minimum at the moment of completion of exhaust stroke when the resilient mounting is not weighted by compression pressure and is extended to its maximum size; and a compression space made by reaction of compression pressure on the piston with completion of compression stroke whereby the resilient mounting is pressed and it is the consequence of the piston' s subsidence in the cylinder for creating of the essential space to compression of the fuel-air mixture.
  • the resilient mounting putting together an internal part of the piston and an external part of the piston or the small end and the big end of a connecting rod or through a gudgeon pin the piston and the connecting rod, which is either a spring resilient mounting or a telescopical one, made so that it is automatically extended to its limit size when the piston is not weighted by compression pressure, and is contracted to its limit size before or when the project compression pressure is reached in the cylinder.
  • a spring resilient mounting By activity of the resilient mounting is reached a better displacement of combustion gases from the cylinder and strengthening up to automatic regulation of the compression of the fuel-air mixture in the cylinder. Owing to the better displacement of combustion gases there is reached a reduction of the fuel-air mixture from the combustion gases. Together it increases ignitability or ignitability by compression and amplifies an expansive force in the cylinder or, in other words, the invention increases efficiency of the internal combustion engines.
  • Figure 1 is a diagrammatic cross-sectional view of the part of a four-cycle internal combustion engine, in the concrete of the part concerning a cylinder block, the part concerning a cylinder head assembly, the four piston assembly, the part concerning of a crankshaft, and the part concerning a crankcase.
  • FIG. 1 shows the best mode of carrying out the invention.
  • the diagrammatic cross-sectional view of the part of the four-cycle internal combust ion engine comprises a cylinder block with four cylinders 1; a cylinder head 2 with an exhaust valve 3 and with an inlet valve 4 for every cylinder 1; a crankshaft 5 with bearing shells 6; four piston assemblies; and a crankcase 7.
  • the piston assembly comprises a connecting rod 8 with a bearing cap 9, a gudgeon pin 10 with two circlips 11 , and the piston.
  • the piston comprises an internal part of the piston 12, an external part of the piston 13, and a resilient mounting.
  • the one-piece internal part of the piston 12 is formed from a barrel side-piece and from a ring rib.
  • the barrel side-piece of the internal part of the piston is furnished by two opposite centre holes 14 for the gudgeon pin 10, which is assured by two circlips 11 there.
  • the ring rib which reinforces the internal part of the piston 12, is furnished by a round dimple.
  • the round dimple is a bed for the resilient mounting.
  • a centric space of the ring rib is for the small end of the connecting rod to its pendulum movement there.
  • the external part ef the piston 13, which is resiliently Jointed with the internal part of piston 12, is equiped with a ring equipment 15, and with a flange 16.
  • the barrel side-piece of the external part of the piston on its open part is thinned inside for putting the internal part of the piston 12 there and for equipage of the external part of the piston by the flange 16.
  • the flange 16 prevents the internal part of the piston 12 and the external part of the piston 13 from getting out from their reciprocal Joint.
  • the length of the thinning of the barrel side-piece te the flange 16 limits the stretehiness and the shrinkage of the resilient mounting.
  • the resilient mounting which resiliented the external part of the piston 13 from the internal part of the piston 12, comprises a coil spring 17, and a ring spring seat 18.
  • the bed of the coil spring is the round dimple in the ring rib which prevents the cell spring 17 from the movement to side.
  • the ring spr ing seat 18 prevents the external part of the piston 13 from the frictioning by the coil spring 17.
  • the resilient mounting is automatically extended to its maximum size when the piston is not weighted by compression pressure and is contracted to its minimum size before or when the project compression pressure is reached in the cylinder 1.
  • Diagram of Figure 1 is also a graphic description of state with completion of every stroke from fourstroke- cycle: Completion of inlet stroke A, completion of compression stroke B, completion of expansion stroke C, and completion of exhaust stroke D.
  • the resilient mounting is stretched to maximum size because on the head of the piston there is not an operation of compression pressure, but on the contrary a vacuum arises with suction in the cylinder 1.
  • the resilient mounting With compression stroke the resilient mounting is pressed in dependence on the growth of compression pressure in the cylinder 1. With the completion of compression stroke B, the resilient mounting is pressed to its limit shrink, provided that there is a sufficient sucked quantum of the fuel-air mixture. In dependance of a quantity of sucked fuel-air mixture into cylinder 1 , the corapression space 20 can be slightly decreased if the resilient mounting has strengthened the compression stroke.
  • expansion stroke C depression of the resilient mounting is dependent upon the expansion force. If the expansion force is sufficient, there results an elongated expansion stroke or, in other words, there is created a maximal expansion space 21 in the cylinder 1.
  • the spontaneous extension of the resilient mounting comes when the expansion pressure after explosion ceases to be effective.
  • the reduced exhausting space 22 is created when the completion of exhaust stroke D, is reached.
  • the industrial exploitatlan of the invention is in the manufacturing of the above.

Abstract

Dans un moteur à combustion interne à quatre temps, une liaison élastique ou télescopique est prévue entre la tête du piston et l'arbre de manivelle (5), la tête de piston étant capable, à la fin de la course d'échappement, de prolonger sa course vers la culasse (2), ce qui fait sortir pratiquement tous les produits de combustion de l'espace de travail (22). La liaison peut être un ressort à compression (17) ou des éléments télescopiques situés entre le piston et la bielle de connexion (8), entre des sectios d'un piston multipièce (12, 13) ou entre la petite extrémité et la grande extrémité de la bielle de connexion (8). La liaison élastique ou télescopique trouve une utilisation dans les moteurs à piston à mouvement alternatif, rotatif ou orbital.
