Definitions

  • the invention relates to a device and a method for crankcase ventilation and recycling of the vent gases in the combustion chamber of a supercharged internal combustion engine according to the preambles of claims 1 and 17 respectively.
  • combustion gases between the cylinders and the piston rings can escape into the crankcase.
  • These gases are referred to as blow-by gases and can build up considerable pressures within the crankcase, so that a venting of the crankcase is required
  • the blow-by gases in the crankcase are loaded with engine oil, so they must not be discharged into the environment and usually pass through an oil separator to finally be passed into the intake of the engine. From here, the gases are returned to the combustion chambers of the cylinders.
  • PCV valves positive crankcase ventilation
  • PCV valves positive crankcase ventilation
  • the negative pressure in the intake tract is used to suck gases from the crank chamber.
  • a turbocharger at partial load operation, the exhausted gas is drawn into the intake stroke downstream of the turbocharger and into the intake tract at full load upstream of the turbocharger.
  • Check valves must prevent at full load that the pressure on the so-called. Part-load ventilation services is transmitted to the crankcase.
  • the extraction of the gases takes place either in the region of the bottom of the crankcase above the oil level or in the region of the cylinder head.
  • the collecting chambers are the spaces in which the venting gas is located in front of the extraction system.
