Definitions

  • the present invention relates to a method for deoiling of crankcase ventilation gases of an internal combustion engine, being an oil separator such as a Cyclone, through which the crankcase ventilation gases flow and the oil droplets contained in it Oil separating element to be separated.
  • an oil separator such as a Cyclone
  • the invention further relates to a device for carrying it out of the process, with one of crankcase ventilation gases flowed through an internal combustion engine Oil separator, such as a cyclone.
  • Oil separator such as a cyclone
  • a procedure of the type mentioned at the outset is fundamental e.g. known from DE 31 28 470 A.
  • Suitable devices of the method are from the practical Operation from a variety of use cases known.
  • the volume flow of the crankcase ventilation gas is depending on operating parameters, such as load status and Speed, the associated internal combustion engine and from the state of wear of the same. This results in the Operation of an internal combustion engine such a large volume flow range, that this disadvantageously with a single Separator can not be covered because the optimal operating state of the separating element only observed in a small area. In other areas e.g. decreases the separation performance at low volume flows below a desired level or at correspondingly larger volume flows exceed that which arises Differential pressure a still permissible value.
  • crankcase ventilation gases it is therefore the object of the invention to provide a method and a device for de-oiling crankcase ventilation gases to be specified for all company sizes of Internal combustion engine work in the optimal range.

  • a second embodiment of the device provides that the at least two downstream oil separation elements are connected in parallel and that the oil separating elements upstream each have their own control element is, depending on the size of a partial stream flowing to it Oil separating element regulates.
  • this second embodiment is a separate control element for each oil separator element necessary, but they can each be advantageous because of the smaller partial electricity volumes to be absorbed in in most cases smaller than the first embodiment be executed.
  • the device is intended to be upstream an additional common control element from the control elements is present, which is the volume flow of the crankcase ventilation gases depending on its size divided into the at least two partial volume flows and this the at least two downstream control elements passes, with control commands from the common control element feedable to the downstream control elements are.
  • the common control element is more suitable here Manner, e.g. through electrical control signal lines, with connected to the downstream several control elements in such a way that control commands from the common control element too the downstream control elements can be forwarded and in particular control signals for opening or closing can be forwarded.
  • the device strikes the invention that the at least two downstream Oil separator elements are connected in parallel and that the oil separating elements each have a flow control element is connected in parallel, the oil separating elements each flow through one of the partial flows are, the size of each by the assigned control element is adjustable.
  • the number is the control elements equal to the number of oil separator elements; the control elements are advantageous here but not fully flowed through by the partial flows, whereby in some cases an even smaller construction of the control elements is possible.
  • Another embodiment of the device according to the invention is characterized in that the at least two downstream oil separator elements connected in series are and that the oil separating elements upstream respectively a control element is connected upstream, each control element depending on the volume flow flowing to it divides it into two sub-streams, one of which in each case one partial stream downstream of the control element Oil separating element flows in and each other substream flows into a bypass line that is on passes the downstream oil separator. at this version of the device can have a too large volume flow bypassed the oil separators if this is permitted in some operating conditions or is desired.
  • control element be a passive element that is immediate over the volume flow or over one exerted by this Force can be actuated. This will on the one hand simple and inexpensive construction and on the other hand achieved high reliability in operation.
  • control element can be an active element be that according to a by measuring the volume flow obtained control signal is actuated. This execution requires a slightly higher technical level Effort, but allows a more precise regulation and enables a stronger influence e.g. on the course of Generally characteristics.
  • a measuring device a Venturi pressure sensor to measure the volume flow comprises and that the control element mechanically, preferably via a valve tappet Control element acting membrane, is actuated.
  • This Execution has the advantage that both the measurement and. also the actuation of the control element on a purely mechanical basis Paths are made so that a conversion from mechanical Measured values in electrical signals or vice versa from electrical signals to mechanical manipulated variables is not necessary.
