Definitions

  • the present disclosure generally refers to a blow-by gas removing device for an internal combustion engine.
  • the disclosure refers to a blow-by gas removing device for removing blow-by gas including oil or oil mist present in a crankcase of the internal combustion engine and for discharging it to an oil separating device.
  • the present disclosure in general relates to a method for removing blow-by gas including oil of an internal combustion engine.
  • the method disclosed comprises the use of rotating power of a rotating engine component of the internal combustion engine for driving a fan wheel configured to remove the blow-by gas, particularly to suck off the blow-by gas out of the crankcase.
  • the present disclosure is directed, at least in part, to improving or overcoming one or more aspects of prior systems.
  • a first aspect of the present disclosure refers to a blow-by gas removing device according to claim 1.
  • Another aspect of the present disclosure refers to a method for removing blow-by gas according to claim 9.
  • Fig. 1 shows a schematic cross-sectional view of a part of an internal combustion engine provided with a blow-by gas removing device.
  • an internal combustion engine 10 comprises a crank shaft 15.
  • the crank shaft 15 rotates about a longitudinal axis 20.
  • a gear wheel 23 is attached to the crank shaft 15.
  • the gear wheel 23 is fitted on an end of the crank shaft 15 by a plurality of bolts 24.
  • the gear wheel 23 is used to drive an oil pump.
  • the crank shaft 15 and all engine components attached can be enclosed by a crankcase 1.
  • crankcase 1 is a housing for the crank shaft 15 and forms a cavity below cylinders in the internal combustion engine 10.
  • a torsional vibration damper 16 is attached to the crank shaft 15 in a non-rotatable manner. And, if the crank shaft 15 rotates during operation of the internal combustion engine, the torsional vibration damper 16 also rotates.
  • the torsional vibration damper 16 is mounted on a shoulder 21 of the crank shaft 15 by means of a plurality of bolts 22.
  • a fan wheel 25 is attached or mounted to a face 17 of the torsional vibration damper 16.
  • the fan wheel 25 is bolted to the face 17 of the torsional vibration damper 16 by means of bolts 22.
  • the fan wheel 25 may be attached to the face 17 by means of an adhesive.
  • the fan wheel 25 may be integrally formed on the face 17 of the torsional vibration damper 16, I particular formed in one piece with the torsional vibration damper 16.
  • the fan wheel 25 may be fitted on a part of the gear wheel 23 or directly on the crank shaft 15. In all cases, the fan wheel 25 has to be mounted non-rotatably on the crank shaft 15 or any other driven engine component which is non-rotatably mounted on the crank shaft 15. As a result, the fan wheel 25 rotates due to rotation of the crank shaft 15.
  • a casing or housing 30 is stationary arranged and encloses the fan wheel 25 and, for example, other rotating components like the torsional vibration damper 16 at least partially.
  • the housing 30 surrounds the gear wheel 23 in such a manner that blow-by gas including oil can be sucked in through a gap 31 provided between the gear wheel's outer circumference and an inner edge of the housing 30.
  • the housing 30 is provided with an outlet or opening 35 at the radial outer side of the housing 30.
  • the opening 35 opens to the outer radial circumference of the fan wheel 25.
  • the opening 35 is part of a connection flange 36 of a connection part 37
  • the connection part 37 is connected to a pipe 38 by means of a bellow 39 configured to compensate length variations due to thermal conditions during operation of the internal combustion engine.
  • the pipe 38 connects to an oil separating device 40 comprising one or more filter elements known in the prior art.
  • the oil separating device 40 is connected to an inlet pipe 55, in which the purified blow-by gas 50 is guided to the entrance site, normally an inlet pipe of the internal combustion engine.
  • inlet pipe 55 connected to the oil separating device 40 is already part of an inlet manifold of the internal combustion engine 10.
  • blow-by gas including oil and/or other particles accumulates in the crankcase 1 of the internal combustion engine 10.
  • a separate fan is provided to remove the blow-by gas 45 from the crankcase 1 and to supply the same to an external oil separating device 40.
  • the fan wheel 25 non-rotatably mounted on the torsional vibration damper 16 rotates together with the torsional vibration damper 16 due to rotation of the crank shaft 15.
  • the blow-by gas 45 is being sucked in, inter alia, through the gap 31 at the radial inner side of the fan wheel 25. Due to the rotation of the fan wheel 25 and the shape of that fan wheel 25, the blow-by gas 45 travels to the radial outer side of the fan wheel 25 and is compressed.
  • the, for example, slightly compressed blow-by gap 45 is discharged through outlet or opening 35 and guided into oil separating device 40.
  • the blow-by gas is purified, and particularly the oil in the blow-gas is separated.
  • the purified blow-by gas 50 is supplied to the environment or to an inlet pipe 55 of the internal combustion engine 10. Alternatively, the purified blow-by gas 50 may be routed back to an intake manifold.
  • the casing may be a separate housing made of sheet metal or a contoured crankcase contour.
  • the fan wheel may be directly integrated into the torsional vibration damper and/or other components rotating together with the crank shaft of the internal combustion engine.
  • any other driven engine component may be used as a rotating support for the fan wheel.
  • the removing of blow-by gas including oil is performed without using a separate auxiliary drive for a common fan configured to suck in the blow-by gas and discharge it to an oil removing device comprising, for example, a filter.
  • an oil removing device comprising, for example, a filter.
  • the power of a rotating engine component is used the first time for driving a fan wheel sucking off the blow-by gas. Consequently, no extra drive is necessary for the blow-by gas removing device.
  • a gas engine is an internal combustion engine which runs on a gas fuel, such as coal gas, producer gas, biogas, landfill gas or natural gas.
  • a gas fuel such as coal gas, producer gas, biogas, landfill gas or natural gas.
  • gas fuel such as coal gas, producer gas, biogas, landfill gas or natural gas.
  • gas fuel such as coal gas, producer gas, biogas, landfill gas or natural gas.
  • gas fuel such as coal gas, producer gas, biogas, landfill gas or natural gas.
  • gas fuel such as coal gas, producer gas, biogas, landfill gas or natural gas.
  • gas fuel such as coal gas, producer gas, biogas, landfill gas or natural gas.
  • blow-by gas and “blow-by gas including oil” mean the same, namely blow-by gas as it is present in an internal combustion engine during operation, in particular blow-by gas present in a crankcase.
  • a device and method as disclosed herein particularly refer to a blow-by recirculation system and a blow-by recirculation method if the blow-by gas removing as disclosed herein is combined with supplying the blow-by gas in the inlet or suction part of the engine.
