Definitions

  • the invention relates to a drive system able to be used in any field involving the use of the engines referred to as internal combustion engine, as well as in the piston compressors, piston hydraulic pumps and similar fields.
  • the mechanisms with closest resemblance to the drive system according to the invention are the internal combustion engines.
  • Internal combustion engines contain the crankshaft, connecting rod, piston and cylinder parts.
  • crankshaft rotates about its own axis, it rotates the connecting rod in an eccentric manner.
  • the piston which is connected to the other end of the connecting rod, inside the cylinder and along the axis of the cylinder.
  • the motion begins with the piston and the piston rod departing from the position referred to as the upper dead centre within the cylinder. This motion towards the middle portions of the cylinder reaches first the maximum speed depending on the revolution of the engine, then becomes zero at the position referred to as the lower dead centre.
  • the speed of the piston and the piston rod reaches from zero to maximum value and from maximum value to zero again, within the 180° rotational movement of the crankshaft of the engine.
  • the power is consumed corresponding to the energy that conveys the weight of the piston and the connecting rod to the maximum speed.
  • the energy is consumed, which equals four times the amount of energy that conveys the weight of the piston and the connecting rod up to the desired speed. Since two complete revolutions of the crankshaft of this engine make up one work period, the power to be spent during one work period is two times the power spent upon four downward-upward motions of the piston and the connecting rod. Therefore, the total energy spent by the piston and the connecting rod during one work period equals eight times the energy that conveys the piston and the connecting rod up to the maximum speed.
  • Vankel engines Another example of the internal combustion engines are Vankel engines. Based on the principle that the vanes that provide the compression in Vankel engines sweep, compress and expand the gas by rubbing against the interior wall of the engine, the considerable heating and abrasion caused by the frictional forces may not be avoided. This system may still not be used with full efficiency at the present.
  • the object of the invention is to develop a drive system that may be used and provide fuel savings in any field involving the use of the engines referred to as internal combustion engine, as well as in the piston compressors, piston hydraulic pumps and similar fields.
  • Another object of the invention is to reduce the release of the emission gases such as, CO 2 , etc., which are harmful to the environment, owing to the less fuel use.
  • the object is also to increase the amount of motion energy received per unit fuel in ideal revolution (being accepted to be approximately 4000 revolutions/minute), compared to the existing piston engines.
  • Another object of the invention is to minimize the mechanical energy losses caused by the connecting rod and the piston, since there is no crankshaft-related connecting rod and piston motion.
  • Another object of the invention is to make it possible to apply the drive system according to the invention also in the Vankel engine system, thus to considerably reduce the distance for the friction carried out by the vanes against the walls and to eliminate the aforesaid drawbacks.
  • the system is provided with power and lifetime that are similar to the efficiency when the same is applied to the piston engines.
  • the axial difference constituting the torque may be made greater owing to the drive system according to the invention and thus, accelerating moment may be increased in an efficient manner.
  • Still another object of the invention is to reduce the lateral pressing motion applied on the cylinder walls by the motion of the piston connected to the crankshaft in the internal combustion engines.
  • Both ends of the connecting bearings of the piston rod may be formed in the same size; hence the piston rod is brought to the lightest state that is possible.
  • Still another object of the invention is to enable the utilization of the alternative material options, having a very low frictional coefficient and being heat resistant, in the cylinders, due to the fact that the system according to the invention will operate without vibration as compared to the engines with crankshaft. Since the piston weights have no substantial effect on the operation of the system, as opposed to the engines with crankshaft, the heavier material alternative may be used in the pistons, other than the aluminum alloys.
  • Still another object of the invention is to enable a vibration-free operation of the system, as there is no action of stop-run during the motion of the piston related to the crankshaft.
