Definitions

  • the invention relates to a gas-dynamic pressure wave machine with the features in the preamble of patent claim 1.
  • a by no means negligible aspect of internal combustion engines is the so-called engine ventilation.
  • Each internal combustion engine generates combustion gases which enter the crankcase not only into the exhaust but also due to the high pressures past the pistons. If you did not divert the gases from there, the pressure in the crankcase would rise sharply with the result that the piston would have to work against this pressure in the crankcase.
  • the pressure conditions in the intake duct thus influence the crankcase ventilation. Since the gases are entrained by the general air flow in the intake passage, no influence can be exerted on the crankcase ventilation.
  • the invention is based on the object to show a gas-dynamic pressure wave machine, by means of which the engine ventilation can be improved.
  • crankcase ventilation is connected to a cold gas housing of the pressure wave machine.
  • connection points can be saved in other areas without the complexity of the already machined cold gas housing of the pressure wave machine would increase significantly.
  • a control disk at the end of the cell rotor has openings, wherein the position of the openings is variable relative to the hot gas housing openings.
  • Such a control disc may have an opening which connects a sucking portion of the cell rotor with an opening of the engine vent line associated with the opening.
  • a separate engine ventilation duct which is assigned to a specially provided opening of a control disk, results in a separation of the general intake air flow from the gases from the engine ventilation duct. As a result, it is much easier to influence the engine ventilation than in cases where the engine ventilation duct opens into the general intake duct.
  • the complete mixing of the intake air with the vent gases takes place only when the respective gases flow into the cell rotor, ie in the low pressure range.
  • the engine ventilation is designed such that the negative pressure conditions in the ventilation duct are adapted to the requirements of the respective engine.
  • the opening in the control disk provided specifically for the engine breather is dimensioned such that even when the control disk is rotated, engine breather is ensured.
  • the opening cross-section of the intake ports of the pressure wave machine can be changed and thus the engine ventilation can be influenced.
  • the opening of the engine breather remains permeable to gases that must be removed from the crankcase.
  • leading to the pressure wave machine line of the crankcase ventilation may have a throttle. It may also be a check valve integrated into the line, so that gas sucked in exclusively via the crankcase ventilation, but can not flow back through the crankcase ventilation to the internal combustion engine.
  • the opening which is provided in the control disk of the pressure wave machine oriented so that it extends in the radial direction relative to the longitudinal axis of the control disk or the cell rotor.
  • the control disc not only has openings that allow an axial flow of cold gas, but also openings that allow a radial flow of the crankcase gas.
  • a compensation chamber is arranged in the cold gas housing, to which the line of the crankcase ventilation is connected and which communicates via the opening in the control disk with a sucking portion of the cell rotor.
  • certain pressure fluctuations can be compensated via the compensation chamber.
  • the compensation chamber has the function that the opening remains gas-permeable even when the control disk is rotated relative to the cold gas housing. This has the consequence that the opening is always coupled to the sucking areas of the gas-dynamic pressure wave machine at a correspondingly large, extending in the circumferential direction of the control disc compensation chamber.
  • control discs In general, the advantage of using control discs is that there are no moving parts in the engine compartment, such as For example, hoses that are connected to a total of adjustable housing. This makes it possible to simplify the line connections to the pressure wave machine. In addition, the mass of the moving parts is greatly reduced, whereby actuators are charged correspondingly less.
  • the installation space of the pressure wave machine according to the invention is smaller than partially rotatable housings. This makes a more compact design possible.
  • control disk can be used simultaneously as a tolerance compensation for the gap between a cold or hot gas housing and the cell rotor.
  • Figure 1 is a schematic view of an internal combustion engine with associated pressure wave machine
  • FIG. 3 shows a detail of the pressure wave charger with control disk of FIG. 2.
  • FIG. 1 shows an internal combustion engine 1 with a high-pressure exhaust gas line 2, which leads to a gas-dynamic pressure wave machine 3, of which a cell rotor 4 is shown by way of example here.
  • the pressurized exhaust gas from the engine 1 serves to compress air sucked on the other side of the cell rotor 4 and supply it to the engine 1.
  • one of the gas-dynamic pressure wave machine 3 for Engine 4 leading Hochdruckladeluft effet 6 is provided.
  • a wastegate 7 is shown schematically in the exhaust area, which connects the high-pressure exhaust gas line 2 with a low-pressure exhaust gas line 8 as a bypass past the gas-dynamic pressure wave machine 3.
  • a throttle valve 10 In a suction line 9 in the cold gas area is a throttle valve 10 to control the inflowing air quantity.
  • a crankcase ventilation 11 which comprises a line 12 which leads from the crankcase 5 of the internal combustion engine 1 into the intake region of the gas-dynamic pressure wave machine 3.
  • a line 12 which leads from the crankcase 5 of the internal combustion engine 1 into the intake region of the gas-dynamic pressure wave machine 3.
  • three different lines are shown. While the line 12 has a constant cross section, a throttle 14 is provided in the form of a constriction in the conduit 13.
  • the line 15 has a check valve 16 instead of the throttle.
  • the check valve 16 is designed so that gas can flow from the crankcase 5 of the internal combustion engine 1 into the intake line 9 or the cell rotor 4, but not from the gas-dynamic pressure wave machine 3 back into the crankcase 5. This is achieved via a spring-loaded valve body, here in the form of a sphere.
  • FIG. 2 differs from that of Figure 1 in that the gas-dynamic pressure wave machine 17 has a control disc 18 in the intake, to which the line 12 of the crankcase ventilation 11 is connected.
  • the reference numbers introduced in FIG. 1 are used.
  • FIG. 3 shows in detail how the connection of the line 12 to the gas-dynamic pressure wave machine 17 is realized.
  • the control disk 18 has axially extending openings 19, via which sucked air can flow into the spatially subsequent cell rotor.
  • the axial opening marked 19 in an edge-side web additionally has an opening 20 which extends in the radial direction.
  • the opening 20 opens into a compensation chamber 21 in the cold gas housing 22, to which the line 12 is connected.
  • the control disk 18 Upon rotation of the control disk 18 relative to the cold gas housing 22 remains the Opening 20 in a position in which the compensation chamber 21 communicates with the opening 19 and thus a housing ventilation is ensured.
