Definitions

  • the invention relates to a line system with a throttle valve, in particular an intake tract an internal combustion engine, according to the preamble of claim 1.
  • the invention relates to a throttle valve for installation in this line system according to the preamble of claim 6.
  • the invention relates to a method for controlling a throttle valve according to the preamble of the claim 7.
  • the intake pipe of the internal combustion engine then has two partial cross sections, the be separated from each other by a partition.
  • the throttle valve is located only in one of the partial cross-sections, resulting in low engine speeds a partial cross section of the intake pipe can be closed. This leaves achieve a reduction in intake noise.
  • the object of the invention is therefore a device for narrowing the cross section to create a piping system that is reliable in operation and inexpensive is in production and has a favorable acoustic behavior.
  • the line system according to the invention has a throttle valve which can be pivoted is arranged in a cross section of the line system.
  • the pipe system leads to a throttling fluid.
  • the throttle valve is dimensioned that it leaves a residual cross-section free in the closed position.
  • Closed position means the position of the throttle valve in which it is the maximum area of the cross section to be throttled is covered. Is the throttle just executed, the closed position is reached when the throttle valve surface is perpendicular to the fluid flow.
  • the throttle valve In this closed position, however, is compared to conventional throttle valves the remaining cross-section is still available for the passage of the fluid. Will the Throttle valve used in the intake area of an internal combustion engine, so a complete closure of the intake cross section is not desired. Therefore, the throttle valve can be dimensioned so that it is in the closed position cannot completely cover the cross-section.
  • the vertical orientation the flap is acoustically very advantageous. That way Sound waves from the internal combustion engine through the intake tract to the mouth of the intake pipe, reflected by the throttle valve. This leads to a Reduction of intake noise because the sound waves do not pass through the system can leave the suction opening. The reflected sound waves are the incoming overlaid, which can lead to partial or complete deletion.
  • the intake noise of the internal combustion engine can above all be reduced in the lower and middle speed range.
  • Whistling noises as they occur with conventional throttle valves, if they are closed except for a gap.
  • the remaining cross section is advantageously annular around the throttle valve arranged.
  • the throttle valve does not have to be round. It’s the same an oval or angular design is conceivable, the cross section of the line system must fit the shape of the flap.
  • the throttle valve can be driven by various actuators. It offer z. B. electric stepper motors or continuously adjustable U-boxes. A stepped adjustment of the throttle valve is also conceivable. Even an embodiment with only two stages, i.e. closed and open throttle valve, which can be controlled inexpensively by a vacuum box the acoustic advantages described. However, the acoustics of the Intake pipe no longer continuously to the operating behavior of the internal combustion engine to adjust. Rather, operational areas are to be defined in which the different Switch positions of the throttle valve are used.
  • the venturi-shaped course of the pipe also has an effect favorably on the acoustics of the intake manifold.
  • the throttle valve does not have to be round. Rather, it can take various forms have, e.g. B. be rectangular.
  • the cross section of the associated line section must be adapted to the shape of the flap. Accordingly, the the throttle valve surrounding and delimited by the walls of the line system
  • the remaining cross section should not be circular.
  • the annular residual cross section rather adapts to the contours. Important when designing the remaining cross-section is just that no areas regardless of the flap position arise in which the distance between the edge of the flap and the wall of the pipe system becomes so low that whistling noises can occur.
  • the acoustic effects described can be used particularly efficiently if the remaining cross section an area share of 10% to 40% of the total area of the Cross section in which the throttle valve is located. This means on the one hand a sufficiently large cross section for the operating states of the engine with maximum Air requirement available, on the other hand, the cross section can be effective by reducing the throttle valve.
  • a throttle valve has the advantages according to the invention, which are obtained during installation in the already described piping system for optimal results regarding the acoustics of the pipe system. This means that flow noise of the fluid to be conducted is reduced and sound waves inside the piping system be dampened.
  • a method is applied according to claim 7, in which the Flap position depending on the amount of the internal combustion engine Combustion air is adjusted. Different parameters can be used as measured variables be used.
  • a simple and inexpensive solution results if as the manipulated variable for the flap angle ⁇ , the speed n of the internal combustion engine is being used. In most engine operating states, this is all in one proportional ratio to its air requirement.
  • the throttle valve At low speeds, then the throttle valve will be closed more and more until it is in its closed position reached. In the upper speed range, the throttle valve is opened completely, so that only the projection of the folding edge the cross section of the intake tract narrowed.
  • the procedure for controlling the throttle valve must always ensure that the internal combustion engine in any operating state with the minimum required Air volume is supplied. However, it can be useful in certain operating states not to limit the air to the necessary minimum, but a larger one To provide intake cross-section. This has the consequence that the intake noise is greater than the minimum value that can be achieved. This is e.g. B. in the acceleration phase of the engine makes sense to give the driver an acoustic feedback to enable the internal combustion engine. This allows the switching times for the corridors to recognize better. However, if the engine is to last for a long time are operated at a constant speed, the lowest possible intake noise wanted.
  • Appropriate control of the throttle valve can be achieved if additionally the acceleration of the engine is detected as a signal.
  • an additional detection of the negative pressure present in the intake manifold Represent controlled variable with which the internal combustion engine is deficient Combustion air can be prevented in any case.
  • FIG. 1 the intake tract of an internal combustion engine 10 is shown schematically. This consists of a venturi-shaped intake 11, an air filter 12, an intake manifold 13 leading to individual cylinders 14, an exhaust 15 the Guaranteed discharge of the burned gases.
  • a throttle valve 16 is accommodated in the narrowest cross section 17 of the venturi tube.
  • the throttle valve 16 according to FIG. 1 is in the fully open state shown.
  • the throttle valve is started from an inlet 18 of the intake manifold flowed to what is indicated by an arrow.
  • the position ⁇ of the throttle valve is set via a stepper motor 19.
  • the Setting is carried out via a control unit 20, the various manipulated variables of the Intake tract evaluates to determine the throttle valve position. For one, can the negative pressure p in the intake manifold can be measured. In addition, the Engine speed n determined, the speed signal can still be below With the help of a timer 21, which supplies the signal t, to determine the Acceleration n can be used.
  • FIG. 2 shows an example of the structural design of the invention Throttle valve 16.
  • the throttle valve is in one piece with a valve shaft 22 and Support ribs 23 made. This unit is injection molded into a flap frame 24, so that there is a throttle valve module 25.
  • This can be used as a standard component can be installed in different pipe systems, including the scope three mounting flanges 26 with holes 27 for screws attached are.
  • the throttle valve is shown in the closed position. Between a flap edge 28 and an inner wall 29 of the flap frame 24 has a residual cross section 30, which can be flowed through by the fluid.
  • the flap can now be opened continuously whereby a by projecting the flap edges on the cross section 17 and opening cross-section bordered by the inner edge of the remaining cross-section always opens further.
  • the maximum opening cross section 31 when fully open Flap is indicated in Figure 2, with the edge of the opening cross section in this Case is formed by the valve shaft 22.
  • the fluid through which the fluid can flow effectively Cross section is calculated from the sum of the remaining cross section and the Opening cross section formed.
  • FIG. 3 The effect of the throttle valve adjustment is shown in FIG. 3.
  • the throttle valve position is adjusted depending on the speed n.
  • the fully closed throttle valve covers 81% of the cross-sectional area.
  • the dashed curves show the intake noise at various throttle valve positions on. It becomes clear that by gradually closing the Throttle valve up to the remaining cross section the intake noise by up to 18 dB can be lowered.
  • the throttle valve can be used to increase the intake noise during the acceleration phase but can also be opened faster than necessary. This increases in these areas the intake noise of the internal combustion engine and enables this way an acoustic feedback for the driver.
  • This mode is represented by curve b.
  • the throttle valve is discontinuous in relation to Speed adjusted. In this way, the intake noise can be influenced as desired, whereby customer requests for a sound design can also be met.
