Definitions

  • the invention relates to an oil separator for the gases of the crankcase of an internal combustion engine according to the preamble of the main claim.
  • an oil separator for the aerosol-containing gases (blow-by gas) of the crankcase of an internal combustion engine is known.
  • This has an essentially rotationally symmetrical filter element through which the ventilation gases flow from an inlet surface to an outlet surface adjacent to a clean gas space.
  • the separated oil is discharged downwards to the oil pan via an oil return.
  • a device for removing oil mist is also known.
  • a negative pressure is generated via an ejector and the crankcase gas is extracted with the aid of this negative pressure.
  • a disadvantage of this prior art is that oil is not separated, so that there is a risk that an excessive amount of oil will get into the intake area of the engine. This danger is eliminated in a variant in that the oil is supplied to the exhaust rather than the intake area. However, this oil mist gets into the ambient air and leads to impermissible emissions.
  • the invention is therefore based on the object of providing an oil separator which is considerably improved in its effectiveness compared to the previously known and which works with as few losses as possible with simple means.
  • the main advantage of the invention according to the main claim is that the vacuum in the intake pipe of an internal combustion engine is not used for crankcase ventilation, as is customary hitherto, but a suitable vacuum generator is provided which generates a constant vacuum under all operating conditions of the engine.
  • the vacuum in the intake manifold is used, it is particularly disadvantageous that the vacuum varies depending on the operating mode of the engine. For example, when idling the intake manifold vacuum is relatively high, while under full load the intake manifold vacuum is almost zero. A high vacuum also occurs when the vehicle decelerates or brakes using the engine. However, especially at full load, the amount of blow-by gases to be vented is high and must therefore be extracted reliably. This can be reliably accomplished with a precisely defined negative pressure, so that oil coking on the turbocharger is prevented and the emission of the engine is reduced.
  • An oil separator is provided for de-oiling the gases, which oil separator has microfibers, which are made in particular from glass fiber material. These microfibers are shaped in a winding element or a star-folded element.
  • the air deoiling element is suitable for removing the smallest residual amounts of oil, oil vapor or the like from the blow-by gases. On the one hand this prevents oil coking on the turbocharger and on the other hand reduces the harmful emissions of the engine.
  • the element for oil separation is provided with a perforated sheet jacket for support.
  • this perforated sheet metal jacket is also suitable for effective protection against damage to the sensitive filter material.
  • the oil separator element is advantageously arranged in a compact container. This container is designed as a cartridge and can be replaced. The exchange can be carried out very easily, as with a spin-on oil filter.
  • the element for generating negative pressure is an ejector nozzle which is pressurized with compressed air.
  • ejector nozzles are simple in construction and very robust since no moving parts are required.
  • the compressed air for the ejector nozzle can advantageously be taken from the compressed air supply of the vehicle and is regulated, for example, via an adjustable throttle.
  • this only applies to commercial vehicles that have their own compressed air supply. In these vehicles in particular, however, the amount of crankcase blow-by gases to be extracted is high and therefore effective de-oiling of these blow-by gases is required.
  • a check valve is arranged in the line for removing the de-oiled gases.
  • the figure shows a schematic representation of an internal combustion engine with an extraction of the crankcase gases.
  • An internal combustion engine 3 has a line running upward from the crankcase 4, through which the crankcase gases flow into a control valve 12.
  • the control valve 12 ensures a constant negative pressure in the Crankcase and consists, for example, of a spring-loaded membrane, which closes the line if the vacuum is too high.
  • the crankcase gases pass into an air deoiling box 14 via a filter head 13.
  • This air de-oiling box works according to the so-called coalescer principle.
  • Micro-glass fiber layers separate oil droplets from the crankcase gases and return them in large drops to the oil circuit via line 23.
  • the deposition process is effective down to the submicron range. This effectively prevents oil from entering the intake manifold of the engine.
  • An air de-oiling element is described in more detail, for example, in DE-OS 33 32 324.
  • the de-oiled vent gases pass through a check valve 15 and an ejector 11 into the return line 21 and are supplied to the intake air there.
  • the ejector nozzle 11 is pressurized with compressed air via line 19 via the compressed air supply to the vehicle.
  • the compressed air of the vehicle is generated by a compressor 5, for example a screw or piston compressor, is fed to an air dryer 7 via a line 17 and from there is stored in the pressure vessel 8 via the line 18. From the pressure vessel 8, the compressed air reaches the brake system of the vehicle via the compressed air line 22, for example. Part of the compressed air is fed into the line 19 via a solenoid valve 9 and a throttle 10 via the branch.
  • the solenoid valve 9 is opened when the engine is started and closed when the engine is switched off, so that the compressed air is not consumed unnecessarily.
  • the throttle 10 is used to set the vacuum required to extract the crankcase gases.
  • the deoiled gases which are fed to the air intake system of the internal combustion engine via line 21, enter the clean air line 16.
  • This clean air line 16 is provided on the input side with an air filter 1, which draws in fresh air in the usual way.
  • a turbocharger 2 is integrated, which has the usual function for an internal combustion engine.
  • the clean air line 16 is also provided with a branch which leads to the compressor, so that the compressed air supply of the vehicle also works with clean air.
  • the negative pressure which is generated by means of the ejector nozzle 11, is dimensioned such that it is sufficient to overcome the flow resistance of the air filter box 14 and a certain constant negative pressure is achieved in the crankcase.
