Definitions

  • the invention relates to a device for removing and returning propellant gas from an internal combustion engine, according to the preamble of claim 1.
  • blower - In addition to the tearing off of the lubricating film in bearings in piston engines between the piston and its cylinder wall due to defective piston rings - so-called blower - occur, leading to a total damage of the piston / cylinder unit ("piston eater").
  • An increase in the oil mist density with a simultaneous increase in temperature as a result of the hot combustion gases suggest such a blower.
  • the object of the invention is to propose an improved device for the removal and return ofmaschineraumgas from an internal combustion engine, in which the disadvantages of the known in the prior art common intake and return line can be avoided without having to forego the advantages described above ,
  • This object of the invention is achieved by a device according to claim 1.
  • the measures of the invention initially have the consequence that a simple external assembly of the device is possible, even with strong engine walls. Due to the slanted channel openings - namely the intake and the return opening - a very good splash guard is given. The assembly is also in the engine compartment lying in the engine compartment interference edges, such. a bulkhead, because of the flexible Elastomerkrümmers possible. Particularly advantageous is a spatially separated intake and return opening through the opening offset.
  • the measuring device and thus also the device according to the present invention is intended in particular for marine engines and also for engines in power plants, ie large diesel engines, but also for smaller engines.
  • the case of possible oil accumulation by the engine inclinations, which can probably never be completely avoided in a marine diesel, are optimally prevented by a kidney structure, so one separated by a partition, preferably in approximately round or oval round double channel. This also closures of the flow channel can be avoided.
  • the application of the inventive device is not limited to the removal for the purpose of oil mist detection, but can also be provided for other applications in which access to the work space is required.
  • An integrated seal for the sensor support bracket is advantageous.
  • the manufacture of the device according to the invention is very simple and therefore cost-effective through the elastomer partition wall in the engine wall fitting.
  • screw-engageable engagement namely a suction and recirculation device 2 according to a preferred embodiment of the present invention performs an intake passage and a return passage through the screwed by means of a motor wall 8 and lockable with a lock nut 14 flange 5 therethrough.
  • the suction channel 16 is provided so that by means of a suction device (in the present embodiment, a Venturi owned 10) engine compartment atmosphere can be sucked out of the housing or engine compartment, while the return passage 18 is provided so that this engine compartment atmosphere is returned to the engine compartment.
  • these channels end from the point of view of the present intervention on a sensor support bracket 12.
  • the intake duct 16 and the return duct 18 are on the motor side from the Flansch5 as a flexible elastomer, against each other by means of an elastomer partition wall 26 round - so if you consider both karnale together formed in approximately kidney-shaped double channel 24. At the ends of obliquely formed, mutually offset by a few cm arranged channel openings 17, 20 are formed.
  • an elastomer manifold 22 with a bending angle of about 125 ° is arranged.
  • the engine wall fitting 8 and the lock nut 14 have seals 6 which seal engagement with the sensor support bracket and against the engine compartment wall.
  • the integrated seal 28 seals the flange 5 from the sensor support bracket 12.
