Definitions

  • crankcases of internal combustion engines are vented via a line opening into the intake duct of the engine. This prevents particles and vapors contained in the gases emerging from the crankcase from being released unburned to the environment by the engine oil.
  • larger amounts of exhaust gas occur due to wear and tear from the cylinder chamber into the crankcase, which can be easily fed to the combustion chamber of the engine via the ventilation line and the intake manifold, so that adequate ventilation of the crankcase is always ensured. Carry these gases but also noticeable amounts of engine oil from the crankcase, which is noticeable in an increased oil consumption of the engine.
  • the object of the invention is now to provide a method and a device with which the oil components in the gases, which are derived from the crankcases of internal combustion engines, are prevented from entering the intake duct of these machines.
  • This object is achieved according to the invention in that the oil components are separated from the ventilation gases of the crankcase of internal combustion engines before the entry of these gases into the intake duct of these machines and returned to the crankcase.
  • a device for performing the procedure rens according to the invention comprises an insertable in the ventilation line between the crankcase and the intake duct of an internal combustion engine. Separating tank for oil with a suction device, preferably designed as a pump, for returning the separated oil into the crankcase.
  • a collecting container for the oil accumulating in the separating container is connected to the separating container and is under vacuum and provided with a suction device for conveying back the separated oil into the crankcase of the internal combustion engine.
  • the separating container can be made very compact, which enables the arrangement of the device according to the invention also on such internal combustion engines, in particular in passenger cars, in which there is little space for additional devices.
  • a throttle point designed as an ejector for evacuating the oil collecting container can expediently be arranged in the outlet connection of the separating container, as a result of which the internal combustion engine can operate throughout the operating period
  • the vacuum in the oil collecting tank is maintained by the wear-free ejector without great technical effort and the oil separated from the ventilation gases of the crankcase is removed from the separating tank.
  • FIGS. 1 and 2 a device for reducing the engine oil consumption of oscillating internal combustion engines is shown schematically in FIGS. 1 and 2.
  • the device shown in FIG. 1 for reducing the engine oil consumption of internal combustion engines consists of a separating tank 1 for the oil which is in the form of particles in the ventilation gases derived from the crankcase of such a machine and steam is included. These gases enter via a nozzle 2 in the direction of arrow A laterally into the separating container 1, in which their flow speed is considerably reduced, as a result of which the oil particles and condensed oil vapors entrained by the gas fail.
  • the separation of the oil from the ventilation gases in the separation container 1 can still be promoted with internals, not shown, such as baffle plates and / or braided or knitted balls.
  • the ventilation gases freed from oil leave the separating container 1 at the head via a nozzle 3 (arrow B) and are fed to the intake duct of the engine.
  • the engine oil recovered in the separating tank 1 from the ventilation gases of the crankcase of the internal combustion engine collects at the bottom of this tank 1, from where it is discharged from the device with a pump 4 in the direction of arrow C and, according to the invention, is conveyed back into the crankcase of the engine.
  • the ventilation gases derived from the crankcase of such a machine enter a separating tank 6 via an inlet connection 5 in the direction of arrow D and leave this tank after separating off the oil particles and vapors an outlet port 7 (arrow E) to be fed to the intake duct of the engine.
  • a throttle point 8 is provided, which is designed as an ejector and evacuates an oil collecting container 10 via a hose or pipe 9. That in the separating tank 6 from the vent gases resulting oil enters the oil collection container 10 via a hose or pipe 11, the oil flow between the separating container 6 and the oil collection container 10 being accelerated by the negative pressure in the collection container 10 and can even take place against gravity.
  • the oil recovered and collected in the collecting container 10 is drawn off with a pump 12 in the direction of arrow F and returned to the oil circuit of the engine.
