Definitions

  • the present invention relates to an output increasing device for reciprocating engines, and more particularly to an output increasing device for reciprocating engines, in which a connecting rod that connects a piston and a cranl pin is arranged to deviate from the center of the crank pin so that main force generated by combustion pressure may pass a position ⁇ cviating from the center of the crank pin, and also the piston and a combustion chamber are disposed with sloped into the crank's rotational direction from a perpendicular line of the center of the crank, to transr ⁇ it greater force to the crank even at the top dead center as well as at a position where the maximum pressure of combustion is produced.
  • FIG. 1 is a front view showing a conventional connecting rod for connecting a piston and a crank pin.
  • FIG. 2 illustrates an operation state of a piston-crank type internal combustion engine using the connecting rod of FIG. 1.
  • a connecting rod 10 at the upper portion of which a connecting member 11 is installed, is connected to a piston 30 in a cylinder 20 with a pin 31 via the connecting member 11, and the lower portion of which is formed integrally with a cap 12 covering a crank pin 40.
  • the cap 12 which is separately removable up and down and joined with each pair of bolts 14A and 14B and nuts 13A and 13B, supports the crank pin 40 to rotate in the inside.
  • a crank shaft 50 is connected to move along the crank pin 40.
  • the conventional internal combustion engine in which the connecting rod 10 is in a perpendicular line V between the piston 30 and the cap 12, is disposed in order that the main force of combustion pressure may pass the center A of the crank pin 40. That is, when the piston 30 in the cylinder 20 reaches the top dead center TDC, the center A of the crank pin 40 and the center of the piston 30 are disposed on a perpendicular line.
  • the ignition plug should be ignited at 4° ⁇ 2° ⁇ 10° ⁇ 2° approximately, prior to the piston reaching the top dead center TDC.
  • the conventional internal combustion engine has drawbacks that the combustion pressure come up to the top dead center after ignition reaches the center of the crank via the connecting rod, thereby increasing noise and causing the abrasion of mechanism
  • FIG 3 illustrates an operation state of a piston -crank type internal combustion engine using a connecting rod in another conventional art.
  • this conventional art in comparison with FIGs 1 and 2, constructs that a connecting rod 60 is inclined into the rotational direction by a predetermined angle with respect to a perpendicular line V. Since other constructions are the same as FIG. 2, the same reference numerals will be used and the description will be omitted hereinafter.
  • an object of the present invention to provide an output increasing device for reciprocating engines, in which a high output generates even at the top dead center as well as at a position where the maximum pressure of combustion is generated due to structural characteristics of engines.
  • Another object of the present invention is to provide an output increasing device for reciprocating engines having high heat efficiency by increasing compression ratios.
  • an output increasing device for reciprocating engines comprising : a crankshaft; a crank pin, having a predetermined radius from the center of the crankshaft, for rotating the crank with rotationally moving around the crankshaft; a connecting rod, the lower portion of which is connected to an upper cap for supporting so that the crank pin can be rotated in the inside, and the upper portion of which is joined to the piston, wherein the connecting rod is inclined by a predetermined angle with respect to a line L linked between the center of the crank pin and that of the crank shaft when the piston is located in the top dead center; and a reciprocating portion, provided with the piston and a cylinder arranged so that the stroke direction of the piston match by a predetermined angle with the line L linked between the center of the crank pin and that of the crank shaft when the piston is in the top dead center.

  • a connecting rod 100 is connected to a piston
  • crank pin 140 141A covering a crank pin 140.
  • the lower portion of the connecting rod 100 is connected on the right end of the upper cap 141A so that the rod 100 may be inclined by a predetermined angle with respect to a line L linking the center A of a crank pin 140 and the center C of a crank shaft 150.
  • the crank pin 140 is supported by the upper and lower caps 141A and 141B joined with each pair of bolts 142A and 142B and nuts 143A and 143B so that the pin 140 can be rotated in the inside.
  • one of important characteristics according to the present invention is that the moving direction of the piston 120 is not in accord with the line L linking the center C of the crank shaft 150 and the center A of the crank pin 140 when the piston 120 is located in the top dead center, and that the piston 120 moves up and down by a predetermined angle. At this time, this angle makes the moving direction of combustion pressure agree with the shaft direction of the connecting rod 100 at the position where the maximum combustion pressure is generated, and has the connecting rod 100 placed very adjacent to the inside wall of the cylinder 110 within a range of not interrupting rotation movement of the crank pin 140.
  • This is intended to cover drawbacks caused by providing the conventional inclined cylinder engine with the connecting rod of the present invention, and improve heat efficiency by a larger compression ratio.
  • the main force generated by the combustion pressure, being transmitted to the crank pin 140 via the connecting rod 100 reaches the position P deviated from the center A of the crank pin 140, and further the direction of force in the cylinder accords with that of the connecting rod at the position where the maximum combustion pressure is generated. Accordingly, the loss of the force becomes less to transmit larger force to the crank.
  • a high combustion pressure is generated around the top dead center during combustion stroke, but since a passage point of this force is deviated from the line L, the main force during combustion is not direct transmitted to the center C of the crank shaft 150, thereby reducing noises and vibration.
  • the length between the center C of the crank shaft 150 and the position P that the combustion pressure reaches is longer than the conventional length Br in the base of a right-angled triangle, and then the longer base shows the increase of outputs.
  • the output increasing device of the present invention provides the cylinder 110 and the piston 120 so that the stroke direction of the piston 120 may match by a predetermined angle with the line L linked between the center A of the crank pin 140 and the center C of the crank shaft 150 when the piston is in the top dead center, thereby removing a knocking caused by increase of a compression ratio and heightening a combustion ratio. Furthermore, the output increasing device of the present invention reduces remarkably a leakage, which abrades the inside wall of the cylinder 110, resulted from compression combustion process. The reason is that when an angle of the connecting rod changes from the left to the right at the top dead center, the connecting rod 100 of the present invention alters the angle before the piston 120 comes to the top dead center, thereby lessening the side pressure. The device also increases the outputs by keeping inertia itself high against the force which is stopped at the top and bottom dead centers.
  • an output increasing device for reciprocating engines in accordance with the present invention can obtain larger outputs than the conventional reciprocating engines and provide of preventing a knocking and relaxing a leakage to thereby extend a machine's life.

Un cylindre (110) est placé de façon que le sens de la course du piston (120) puisse former un angle prédéterminé avec ladite ligne (L). Par conséquent, le dispositif permet d'augmenter la force de rotation et de prolonger la vie utile du moteur.
