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.
- the solution of the part of the device Task is carried out with a generic device the characterizing features of claim 2.
- the device according to the invention is characterized by Means for dividing the volume flow into at least two Partial volume flows, at least two downstream oil separation elements and at least one rule element that in Depending on the size of the volume flow flowing to it regulates at least one of the partial volume flows.
- This device can be the method specified above practically perform.
- the at least two downstream oil separating elements are connected in parallel and that the Oil separation elements upstream a common control element is connected upstream, the volume flow of the crankcase ventilation gases depending on its size divided into the at least two partial volume flows and this feeds the at least two oil separating elements.
- 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.
- control element directly in the gas inlet of the associated oil separator is arranged and that by means of the control element, the inlet cross section of the oil separating element between an open and a closed position, preferably continuously or in several stages, is changeable.
- control element be immediate arranged in the gas outlet of the associated oil separating element and that by means of the control element, the gas outlet cross section of the oil separating element between one Open and closed position, preferably continuously or in several stages, is changeable.
- control element and additional control element each one by weight or spring force in the closing direction include preloaded valve ball, the valve ball of the control element has a larger diameter than the valve ball of the additional control element and where the two valve balls through a coupling element for common Adjustment are interconnected. hereby becomes a common and like-minded movement the valve balls and thus a coupled adjustment guaranteed by control element and additional control element.
- the coupling element is in its simplest design a thin and connecting the two valve balls lightweight rod with the two valve balls vividly forms an asymmetrical dumbbell.
- a volume flow 2 is again in four sub-flows 21 to 24 divided, after which each partial stream 21 to 24 again divided into two flow paths by a pair of oil separators connected in parallel 1 and a control element 3 flows, after which the two flow paths are combined and also the four partial streams 21 to 24 again to a common de-oiled volume flow 2 flow together.
- the volume flow 2 initially flows in its Entirety through a common first control element 3 ', after leaving it into four sub-streams 21 to 24 to be divided, after which each partial stream is divided by a Control element 3 flows and then through an oil separator 1, whereupon the four sub-streams become one again common de-oiled volume flow 2 are combined.
- signal transmission means 5 e.g. electrical Control signal lines, between the common first Control element 3 'and the four control elements 3, the Control signals transmitted, indicated by dashed lines. It can be seen that the common control element 3 'with each individual downstream control element 3 through the signal transmission means 5 in connection stands.
- Figure 5 shows an embodiment in which the common Volume flow 2 first passed into a control element 3 in which it is divided into two sub-streams.
- the a partial flow flows down in FIG. 5 and then to the right through a bypass line 4, so touches no oil separator.
- the other partial flow flows through an oil separating element 1 and further to a downstream one Control element 3, again a division as done in the first stage.
- a first partial flow flows into the bypass line 4 and the other Partial flow through an oil separator 1 and from there continue to a third control element 3.
- FIG. 6 An embodiment is shown in a schematic representation in FIG shown the device, the two connected in parallel Cyclones as oil separators 1 and one has individual control element 3.
- the volume flow 2 is divided into two partial streams 21, 22.
- the first partial stream 21 becomes a first one, in FIG. 6 Cyclone 1 shown above through its gas inlet 11 fed.
- the clean gas leaves the cyclone 1 upwards through a gas outlet 12, while the oil separated by the one provided below Oil outlet 13 flows off.
- the second cyclone 1 is connected to the second partial stream 22 the crankcase ventilation gases.
- This Cyclone 1 is the control element 3 upstream, which here by a ball valve preloaded in the closing direction 31 is formed. Due to the preload in Closing direction at low volume flow 2 is the control element 3 closed; only when the Volume flow 2 opens the valve 31 due to the increasing Volume flow, here of partial flow 22, e.g. by a force exerted by the latter on the valve ball.
- the control element 3 becomes parallel to the first Cyclone 1 now also the second cyclone 1, which is shown in FIG shown below, from a partial flow of the crankcase ventilation gas flows through. This is how she works Device for both small and large volume flow each in a favorable separation area the cyclones 1.
- the Oil outlets 13 of the oil separating elements 1 in a common Oil collection container which is located directly on the oil outlets 13 connects.
- the oil reservoir via a valve, a so-called anti-return valve, connected to the crankcase. That way avoided that the oil outlets 13 of the oil separating elements be subjected to the crankcase pressure.
- the anti-return valve can also be designed as a siphon his.
- the gas inlet or gas outlet closed via the control element 3 is to prevent, this oil outlet 13 has an additional control element 3 '' on opposite the oil outlet 13 can shut off or open the oil reservoir.
- FIG. 7 of the drawing shows an exemplary embodiment in cross section for a cyclone 1 with an upstream Control element 3 in the form of a valve 31.
- the valve 31 is here as a prefabricated unit in a pipe socket, which in the course of the partial flow 22 to the gas inlet of the Cyclones 1 is installed, pressed in here.
- the spring is preloaded on a valve plate in the closing direction. Through the partial flow 22, if the partial flow 22 is sufficiently large, the valve plate from Valve seat can be lifted against the force of the spring, so that the partial flow 22 through the control element 3 through to the gas inlet 11 of the cyclone 1 and then flows through the cyclone 1. At the center of the cyclone 1 part of the gas outlet 12 can still be seen.
- Figure 8 of the drawing shows an example of a cyclone 1 as an oil separator, in which a control element 3 in the gas outlet 12 and an additional control element 3 '' is provided in the oil outlet 13.
- the gas to be cleaned passes through the gas inlet at the top left of cyclone 1 11 inside the cyclone 1 and is in this set in a rotating flow.
- the control element 3 in the gas outlet 12 is here by a Valve ball 32 formed on one at the top of the dip tube 12 'molded annular valve seat rests.
- a second valve ball 33 is arranged, which in their lower position closes the oil outlet 13, like this is shown in Figure 8.
- the valve ball 32 of the control element 3 and the valve ball 33 of the additional control element 3 '' are straight through a coupling element 34 running thin and light rod, mechanical interconnected so that they can move in Carry out vertical direction together.
