Definitions

  • the invention relates to a device according to the preamble of the main claim.
  • a device is already known (DE-OS 32 34 468), in which, however, there is the disadvantage that the complete opening of the control opening, starting from an opening of the control opening forming an emergency running cross-section, can only be reached after the maximum control path of the throttle element has been run through , for which the maximum control current is required to excite the servomotor.
  • Such a device serves to regulate the idle speed of internal combustion engines in order to achieve favorable consumption and emission values at the lowest possible speed.
  • the lowest possible idling speed depends on various operating states of the internal combustion engine, for example on the load condition, the outside and engine temperature or the power requirement of systems which are driven by the internal combustion engine, for example an air conditioning system.
  • the device according to the invention with the characterizing features of the main claim has the advantage, in contrast, that when the spring element is ineffective, for example broken, and the actuator is energized, the throttle element can be moved into a position that opens a safety cross section of the control opening, so that not only safe continued operation of the internal combustion engine is guaranteed, but is also avoided, for example, that the internal combustion engine reaches undesirably high speeds.
  • the throttle element is particularly advantageous to move the throttle element beyond its position closing the control opening into the position opening the safety cross section. It is furthermore advantageous to provide the throttle element with at least one throttle opening which, starting from a position opening the emergency running cross-section, opens the at least one control opening more or less when the throttle element moves, the control openings or throttle openings having a rectangular or square cross-section can have and the security cross-section of the control opening can be opened by a control edge of the throttle element.

  • Figure 7a to d a simplified representation of the Ste A throttle element configured with two throttle openings compared to two control openings in a third exemplary embodiment.
  • the amount Q of equipment to be controlled for example the amount of idle air for the internal combustion engine to be controlled when an internal combustion engine is idling, is shown in a diagram over the adjustment path s of a throttle device of a device, as described in the following text is described using various exemplary embodiments.
  • combustion air flows in the direction of arrow 1 through an intake pipe 2 past a throttle valve 3 to an internal combustion engine (not shown).
  • the intake pipe 2 is connected to a bypass line 5, which leads around the throttle valve 3 and whose passage cross section can be changed by the device 6 by means of a throttle element 7.
  • the device 6 is controlled by an electronic control unit 8 at which the supply voltage supplied by the vehicle battery at 10, the signal for the speed of the internal combustion engine taken from the ignition distributor of the internal combustion engine at 11, and the signal for the engine temperature at 12 and at 13 there is a voltage which characterizes the position of the throttle valve 3 and which, for example, supplies a potentiometer connected to the throttle valve 3. If necessary, further operating parameters of the internal combustion engine can be input to the electronic control unit 8.
  • the servomotor of the device 6 is an electric motor 15, not shown, which can be controlled by the electronic control unit 8 via a plug 16 as a function of operating parameters of the internal combustion engine
  • the electric motor 15 rotates a hollow shaft 17, which is rotatably mounted about an axis 19 via roller bearings 18, which is pressed into a housing base 21 of a pot-shaped housing 22 of the device 6 and is fixed therein.
  • the throttle element 7 is connected in a rotationally fixed manner, which is designed in the form of a tubular segment and projects into a pivot space 24 designed in the housing base 21 and intersecting the bypass line 5.

If the power supply to the device 6 fails, the amount of operating fluid flowing over the emergency running cross-section 36 is sufficient to provide a favorable fuel / air mixture for the internal combustion engine to continue or to let a predetermined, favorable amount flow to the engine when the internal combustion engine starts.

  • the characteristic curve shown ensures that even in the most unfavorable starting conditions of the internal combustion engine, in which the supply voltage of the motor vehicle battery has dropped due to low starting temperatures and a current requirement for other units of the internal combustion engine, this low supply voltage is still sufficient to place the throttle element 7 in one position s to move, in which a mostly required maximum amount of operating fluid Q can flow via the bypass line 5 for the safe start and continued operation of the internal combustion engine.

Abstract

Un inconvénient des dispositifs connus de commande du ralenti de moteurs à combustion interne est le fait qu'une ouverture totale de la section transversale de commande n'est atteinte que lorsque le trajet maximum d'ajustement n'a été traversé, ce qui permet d'obtenir une ouverture totale de la section transversale d'étranglement même avec une faible énergie d'alimentation fournie par la batterie du véhicule. Un organe d'étranglement (7) susceptible d'être mis en rotation par un moteur électrique comprend une ouverture (31) triangulaire d'étranglement qui à l'état non-excité du moteur électrique (15) ouvre une ouverture (29) de commande ayant la forme d'un parallélogramme et ménagée dans le dispositif et forme partiellement une section transversale d'urgence (36). Lorsque le moteur électrique (15) est excité, l'organe d'étranglement (7) et premièrement mis en rotation jusqu'à une position dans laquelle l'ouverture d'étranglement (31) ouvre complètement l'ouverture de commande (29) et ce n'est que par la suite, en ajustant effectivement la section transversale d'étranglement par une mise ultérieure en rotation, que l'on peut ouvrir dans une plus grande ou moindre mesure l'ouverture de commande (29) au moyen de l'ouverture d'étranglement (31). Le dispositif est utilisé pour régler le ralenti dans des moteurs à combustion interne.
