Definitions
- the invention relates to a device for de-oiling crankcase ventilation gases an internal combustion engine having at least one oil mist separator, the one with the crankcase connected gas inlet and connected to the air intake tract gas outlet and having an oil outlet connected to the oil sump of the internal combustion engine.
- blow-by gases pass into the crankcase interior, which have to be removed, since otherwise an undesirable increase in the internal pressure in the crankcase would occur.
- the blow-by gases are fed back as crankcase ventilation gases via a vent path to the air intake tract of the internal combustion engine.
- the gas inlet-side pressure range as the 1st pressure range (p1) and the gas outlet side Pressure range referred to as 2nd pressure range (p2).
- the differential pressure drop across the oil mist separator thus directly causes a Drukkerhöhung in the crankcase.
- the degree of separation of the oil mist separator depending on the pressure difference.
- ⁇ lnebelabscheider are preferably cyclones or so-called Koaleszenzabscheider used in the form of a knit or Wickelabscheiders.
- a cyclone oil mist separator is known for example from DE 42 14 324 C2
- a deoiling with a Koaleszenzabscheider is described in DE 197 29 439 A1.
- the object of the invention is therefore an apparatus for de-oiling crankcase ventilation gases to develop the oil mist under all operating conditions causes and avoided with the impermissible pressure increases in the crankcase.
- the device according to the invention uses a controllable with respect to its flow bypass channel vision, which is arranged as a bypass parallell to ⁇ lnebelabscheider in the crankcase ventilation path for this purpose, the bypass channel directly or indirectly with the crankcase (1st pressure area) connected gas inlet and a direct or indirectly connected to the air intake tract (2nd pressure area) connected gas outlet.
- the bypass channel together with its control means is thus designed so that an oil separation in the bypass channel is also effected in the bypass channel due to flow deflection and impact separation or as a result of impaction.
- separation behavior of the entire device oil mist separator plus controllable bypass channel
- the degree of separation is still sufficiently high, even when the bypass is open to divert the separated oil in the bypass channel of the bypass channel, for example via an oil outlet connected to the oil sump.
- the oil mist separator is designed to operate for a given volume flow has a certain degree of separation, which then also a certain differential pressure drop is implied. Care is taken in determining the operating point, that the differential pressure plus possibly a certain tolerance range below a is critical for crankcase pressure.
- the inventively controllable bypass acts in the same way in a knitted or Wickelabscheider, which at the same volume flow due to contamination in the Over time, produce a significantly increased differential pressure of the overall device would.
- a sensor is provided which detects whether the bypass channel is open or not opened bypass channel (valve in the open position) is then an optical or acoustic Warning signal for the operator of the internal combustion engine generated This signal is then an indication that he knitted and Wickelabscheider a certain degree of contamination has reached. The operator can then react accordingly and the Replace knit or wound separator.
- differential pressure limiting effect of the controllable bypass channel naturally arises not only with differential pressure increases occurring after a certain time due to wear of the internal combustion engine or contamination of the oil mist separator, but also in the case of temporary differential pressure increases.
- FIG. 1 shows a schematic arrangement of the device (1) according to the invention in the venting path.
- the device (1) consisting of oil mist separator (2) and controllable Bypass passage (3) is between the crankcase (5) to be vented and the air intake tract (6) arranged in the air intake tract (6) prevailing vacuum can in certain Operating conditions of the internal combustion engine increase sharply.
- a so-called crankcase vacuum control valve (9) which is arranged here before the oil removal device (1) Die Gas inlets (2A, 3A) of the oil mist separator (2) and the bypass channel (3) are so Therefore, indirectly via the crankcase vacuum control valve (9) with the pressure range of Crankcase (5) connected.
- the gas inlet side pressure is marked as 1st pressure range
- the gas outlets (2B, 3B) of the oil mist separator (2) and the bypass duct (3) are here connected directly to the air intake tract (6) marked as the second pressure range.
- crankcase vacuum control valve (9) behind the deoiling (1) arranged.
- FIG. 3 shows two differential pressure / volume flow characteristics for a cyclone separation device shown.
- the solid line refers to a cyclone without the controllable one Bypass channel.
- the dashed line on an embodiment of the invention Device consisting of cyclone and controllable bypass channel. How to recognize can, increases the differential pressure in a cyclone oil mist separator with increasing flow drastically. In particular, at wear of the internal combustion engine, the Volume flows permanently be so great that the associated differential pressure increase is indefensible This pressure increase counteracts the inventive device. As you can see from the diagram, opens at a certain flow, the a critical pressure drop across the cyclone automatically causes the bypass channel, so that the further increase of the differential pressure with increasing volume flow much flatter runs.
- FIG 4 are two degrees of separation / volume flow characteristics for a cyclone separator shown.
- the solid line refers to a cyclone without the controllable one By-pass, the dashed line on an embodiment of the invention Device consisting of cyclone and controllable bypass channel. How to recognize can, even if the bypass channel is still open, have a good separation efficiency - even if this is lower than in a cyclone oil mist separator without bypass channel.
- FIG. 6 shows an enlarged view the bypass channel in the region of the valve body to illustrate the oil mist separation according to the impaction principle.
- the spring-loaded valve body acts as a baffle plate of a dynamically adapting impactor whose flow gap (S) is adjustable via the valve spring differential pressure dependent.
- the device according to the invention thus has the design point of the oil mist separator a high degree of separation, while at high flow rates overpressure in Crankcase is reliably avoided, whereby even then a sufficiently high degree of separation is effected.
- FIG. 5 shows a section through an embodiment of the invention.
- the oil mist separator as a cyclone (2) is formed on the integrally the bypass channel (3) is arranged
- cyclone (2) and bypass channel (3) are integrally formed by injection molding, whereby the device according to the invention can be produced inexpensively.
- the oil mist separator (2) and the bypass channel (3) which are formed here as an integral unit, housed in a receiving housing (7), which is only hinted at here.
- the receiving housing (7) is connected to the first pressure range, so that the gas inlets (2A, 3A) of cyclone (2) and bypass channel (3) in the interior of the receiving space (7) with the pressure p 1 are applied.
- the gas outlets (2B, 3B) of cyclone (2) and bypass channel (3) are compared with the pressure area inside the receiving housing (7) sealed out of this out in the second pressure range (to the air intake) out.
- the gas outlets (2B, 3B) of the cyclone (2) and bypass channel (3) open into a sealed space (8) connected to the second pressure zone. Due to the integral assembly (cyclone + bypass channel) and the installation in a pressure-tight receiving housing (7) can be dispensed with separate, otherwise doubled connecting lines from the crankcase to the gas inlets from the gas outlets to the air intake.
- a means (4) for differential pressure-dependent opening and closing is in the bypass channel (3) one of a compression spring (4C) acted upon valve body (4A) - here a valve plate - arranged.
- a predetermined opening pressure difference the valve body (4A) of the compression spring (4C) against a valve seat arranged in the bypass channel (3) (4B) pressed into a closed position.
- the valve body (4A) against the compression spring (4C) releasing a flow gap (S) raised from the valve seat (4B).
- the opening pressure difference results from the spring constant and the flowed surface of the valve body (4A).
- the compression spring (4C) with a targeted, Bias matched to the opening pressure difference in the bypass channel (3) install.
- the installation length of the compression spring (4C) in the differential pressure State adjustable can be done, for example, by (not shown) that the Compression spring (4C) at its end facing away from the valve body (4A) on a support element (4D) is supported in the bypass channel (3) whose axial distance from the valve seat (4B) is adjustable.
- valve body with compression spring and a valve body can be used, that of gravity below a certain opening pressure difference against the valve seat is pressed in a closed position, wherein above the opening pressure difference of Valve body is lifted from the valve seat with release of the flow gap.
- a Hubbegrenzugnsanschlag (not shown) may be provided.
- a throttle valve arranged in the bypass channel or an opening can be used under bias closing leaf valve (both embodiments are not shown), which also cause a de-oiling by impaction.
- the oil sump wherein the oil separated from the cyclone (2) via a drain valve disposed on the oil outlet (2C) (2D) gets into the oil sump.
- the oil separated from the bypass channel (3) can escape via the gas inlet (3A) and directly or via an intermediate reservoir (not shown) flow back into the oil sump or -drop.
