Definitions

  • the invention relates to a device for saving fuel when stopping motor vehicles for a short time, in which the ignition is temporarily switched off.
  • the ignition is temporarily switched off.
  • a starting aid for internal combustion engines with fuel injection has also become known, in which, after a failed start (e.g. with a cold engine), a restart is only possible after a predetermined time has elapsed.
  • a failed start e.g. with a cold engine
  • the ignition system and / or the fuel supply is switched off automatically when the vehicle comes to a standstill.
  • this device is not suitable for driving, especially in cities, because if the engine is brought to a standstill every time the vehicle comes to a standstill, the starter must first be actuated when starting again. When driving in cities, it is often necessary to stop for a very short time, e.g.
  • the object of the invention is to provide a device which is free from the disadvantages mentioned above, a considerable saving of Fuel when motor vehicles are stopped for a short time, which can be produced with little technical effort, is easy to use and can also be retrofitted with existing motor vehicles.
  • This object is achieved in an invention of the type mentioned above in that, depending on whether the engine reaches a predetermined minimum speed or not, either the ignition is interrupted by actuating a button, but the other electrical devices such as horn, turn signals, lamps, Keep the windshield wipers switched on, or switch on the ignition and actuate the starter.
  • the device according to the invention shown in FIG. 1 consists of a button 1 surrounded by a dashed line and a device 2 surrounded by a dashed line and designed as a compact unit.
  • the battery 3, the ignition lock 4, the ignition coil 5 and the starter 6 and the alternator 7 is shown symbolically.
  • the device 2 contains an ignition relay 10 with a changeover contact, a changeover relay 11 with a changeover contact and a starter relay 12 with a changeover contact and a make contact. These three relays are shown in the rest position, i.e. when the relay coil is not energized. The position of the relays shown in the figure applies both to the case that the engine is running with the ignition switched on and to the case that the engine is stopped when the ignition is not switched on.
  • a diode 14 is switched on, which is permeable to a current flow to the alternator and thus to the ground, but blocks an opposite current flow.
  • a resistor 15 is connected in series with this diode 14 and limits the current flow flowing through this diode.
  • a diode 16 is switched with such a forward direction that only a current flow from the normally closed contact 11 R to said end of the relay winding is possible, but is blocked in the opposite direction.
  • a diode 17 connected between the end of the relay winding of the ignition relay 10 connected to the positive pole of the battery 3 on the one hand and $ the normally closed contact 11 R of the changeover relay 11 on the other hand with a forward direction such that only a current flow from this normally closed contact to the ignition relay 10 possible, but is blocked in the opposite direction.
  • the respective position of the changeover relay 11 depends on whether or not the voltage generated by the alternator 7 exceeds a predetermined minimum value.
  • the alternator no longer outputs any voltage and current flows from the positive pole of the battery via the ignition lock 4, the relay winding of the switching relay 11 and the diode 14 to the alternator 7 and through this to the ground.
  • the changeover relay picks up and the normally open contact 1 A is connected to the normally open contact 11 A. If button 1 is now pressed in this switching state, then current flows from the positive pole of the battery 3 via the ignition lock 4 to the normally open contact 11 A and through the relay winding of the starter relay 12 to the negative pole of the battery.
  • the starter relay 12 will attract and close the normally open contact 12 A, whereby the starter 6 is connected to the positive pole of the battery 3 and thus switched on.
  • the changeover contact of the starter relay 12 is moved from the position shown to the other position, thereby interrupting the self-holding circuit of the ignition relay 10 previously effected via the normally closed contact 12 R, so that the ignition relay 10 drops out and current can thus flow to the ignition coil 5 again.
  • Switching relay 11 is still activated since there is no voltage potential from the alternator 7.
  • Starter relay 12 is actuated and releases the self-latching of ignition relay 10 and applies negative potential to changeover relay 11. Starter 6 receives voltage, the engine starts.
  • Switching relay 11 remains energized until button 1 is released. As soon as the alternator 7 supplies voltage, the changeover relay 11 drops out when the button 1 is released.
  • the button has a double function. If the engine is stopped, pressing the button starts the engine using the starter. If the engine is running, the engine is switched off by pressing the button.
  • the starter relay 12 is replaced in the device 2 by a starter relay 12 'with a normally open contact and a starter changeover relay 12 "with a changeover contact .
  • the current flows from the positive pole of the battery via the ignition switch 4 to the normally open contact 11 A and via the diode 19 and the relay winding of the starter changeover relay 12 ′′ further via the diode 14, the resistor 15 to the alternator 7
  • the changeover contact from 12 "R to 12" A there is an additional current flow from contact 11A via diode 18, relay winding 12 'to contact 12 "A and from there to ground .
  • the self-holding of the starter relay 12 ' is effected simultaneously via the diode 20.
  • a diode 21 is additionally provided, which prevents the above-mentioned in connection with Figure 1 S p annungspotential the switching relay 11 is influenced by the current flowing through the STARTER RELAY 12 '.
  • the embodiment shown in Figure 4 is a variant of the embodiment shown in Figure 2. It differs from this essentially in that two separate buttons are provided instead of the change button 1 ', namely a button 1 (analogous to FIG. 1) and a further button 1' '. While the button 1 in the embodiments according to FIG. 1 and FIG. 3 both causes the engine to be switched off and started again, this button 1 in FIG. 4 only serves to switch off the engine. The button 1 "serves to restart the engine. This button 1" receives voltage only after the button 1 has been actuated by the changeover relay 11 and the ignition relay 10 being activated and the contacts 11 A and 10 A being closed.
  • a self-holding circuit of the starting relay 12 ' is provided.
  • the self-holding of the starter relay 12 ' is established with a current flow of 12'A via the diode 20 via the starter switch relay 12 ".
  • the diodes 18 and 14 have the same function as the diodes 19 and 14 (in the exemplary embodiment in FIG. 3 already described).
