Abstract

The invention relates to a motor vehicle having a self-igniting internal combustion engine with injection, which can be turned off in that when the starter switch is in an appropriate position, a low pressure pipe leading to the injection pump is unblocked and the delivery of fuel by the latter is switched off owing to the low pressure then prevailing at the injection pump. To make such a vehicle theft-proof, it is now proposed to provide a bypass pipe leading from the low pressure source to the injection pump and to arrange in this pipe a solenoid valve which is to be actuated independently of the starter switch. When the antitheft system is switched on, the vehicle cannot be started, owing to the fact that the delivery of fuel is switched off.

Description

"Diebstahlschutzvorrichtung für Kraftfahrzeuge""Anti-theft device for motor vehicles"

Die Erfindung betrifft eine Diebstahlschutzvorrichtung für Kraftfahrzeuge mit selbstzündender Einspritzbrennkraftmaschine, bei denen beim Bewegen des Schlüssels des Anlaßschalters in die Stellung Brennkraftmaschine Stop" eine Unterdruckleitung von der Brennkraftmaschine oder einem Unterdruckvorratsbehälter zur Einspritzpumpe freigegeben und durch den dann an der Einspritzpumpe anliegenden Unterdruck die Kraftstofförderung abgeschaltet wird.The invention relates to an anti-theft device for motor vehicles with self-igniting internal combustion engine, in which when moving the key of the starter switch to the position "internal combustion engine stop" a vacuum line from the internal combustion engine or a vacuum reservoir to the injection pump released and the vacuum then applied to the injection pump Fuel delivery is switched off.

Es ist bereits verschiedentlich vorgeschlagen worden, als Diebstahlsicherung die Kraftstoffleitung von mit Brennkraftmaschinen ausgestatteten Fahrzeugen durch ein Ventil absperrbar auszubilden. Dies schließt jedoch die Möglichkeit nicht aus, das Fahrzeug mit dem z.B. in der Einspritzpumpe vorhandenen Kraftstoffvorrat doch erst einmal in Bewegung zu setzen, wobei z.B. ein bereits unmittelbar danach durch den unbefugten Benutzer verursachtkUnfall nicht auszuschließen ist.It has been proposed several times as an anti-theft device the fuel line of vehicles equipped with internal combustion engines to design a shut-off valve. However, this does not preclude the possibility the vehicle with the fuel supply in the injection pump, for example first of all to set in motion, e.g. one immediately afterwards causing the unauthorized user an accident cannot be ruled out.

Der vorliegenden Erfindung lag daher die Aufgabe zugrunde, diesen Nachteil zu vermeiden und einen Kraftwagen der vorstehend beschriebenen Gattung so auszugestalten, daß für einen Unbefugten das Inbetriebsetzen der Brennkraftmaschine nicht möglich ist.The present invention was therefore based on the object of this Avoid disadvantage and a motor vehicle of the type described above designed so that an unauthorized person can start the internal combustion engine not possible.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß eine den Anlaßschalter umgehende Bypassleitung von der Unterdruckquelle zur Einspritzpumpe vorgesehen ist, und daß im Zuge bzw. an einem Ende dieser Bypassleitung ein Magnetventil angeordnet ist, das unabhängig vom Anlaßschalter betätigbar ist.According to the invention, this object is achieved in that a starter switch an immediate bypass line is provided from the vacuum source to the injection pump, and that a solenoid valve is arranged in the course of or at one end of this bypass line is that can be operated independently of the starter switch.

Das Betätigen des Magnetventils kann dabei z.B. über einen versteckt angeordneten, separaten mechanischen Schalter, über einen Steuercode, über eine optoelektrische Steuerung oder über Kombinationen dieser Maßnahmen erfolgen.The actuation of the solenoid valve can be hidden e.g. via a arranged, separate mechanical switch, via a control code, via a optoelectronic control or a combination of these measures.

Der Gegenstand der Erfindung soll im folgenden anhand von zwei in der Zeichnung als Schema dargestellten Ausführungsbeispielen näher erläutert werden.The subject matter of the invention will hereinafter be based on two in Embodiments shown in the drawing as a scheme are explained in more detail.

Eine in Fig. 1 der Zeichnung angedeutete selbstzündende Brennkraftmaschine 1 wird über eine Einspritzpumpe 2 in nicht dargestellter Weise mit Kraftstoff versorgt. Zum Stillsetzen der Brennkraftmaschine 1 wird der Einspritzpumpe 2 Unterdruck zugeführt, der die Förderung der Einspritzpumpe 2 abschaltet.A self-igniting internal combustion engine indicated in FIG. 1 of the drawing 1 is supplied with fuel via an injection pump 2 in a manner not shown. To shut down the internal combustion engine 1, the injection pump 2 is supplied with negative pressure, which switches off the delivery of the injection pump 2.

Dies geschieht im Normalfall über eine von der Brennkraftmaschine 1 zur Einspritzpumpe 2 führende Unterdruckleitung 3, die durch ein Ventil 4 bei entsprschenaer Stellung des Schlüssels 5 eines Anlaßschalters 6 freigegeben wird. Unter Umgehung des Anlaßschalters 6 kann die Einspritzpumpe 2 aber auch über eine Bypassleitung 7 mit Unterdruck versorgt werden, in deren Verlauf ein Magnetventil 8 angeordnet ist, das über eine separate Bedieneinheit 9 betätigbar ist. Die Bedieneinheit 9 wird über eine von der Stellung des AnlaD-schalters 6 unabhängige elektrische Leitung 10 mit Strom versorgt und ist über eine weitere elektrische Leitung 11 mit dem Magnetventil 8 verbunden.This is normally done via one of the internal combustion engine 1 leading to the injection pump 2 vacuum line 3, which is through a valve 4 at Entsprschenaer position of the key 5 of a starter switch 6 is released. Under However, the injection pump 2 can bypass the starter switch 6 can also be supplied with negative pressure via a bypass line 7, in the course of which a solenoid valve 8 is arranged, which can be actuated via a separate operating unit 9 is. The operating unit 9 is independent of the position of the system switch 6 electrical line 10 is supplied with power and is via a further electrical Line 11 is connected to the solenoid valve 8.

In der Darstellung nach Fig. 2 der Zeichnung sind gleiche 3anteile mit gleichen Bezugszahlen versehen wie in Fig. 1.In the illustration according to FIG. 2 of the drawing there are equal 3 parts provided with the same reference numbers as in FIG. 1.

Etwas unterschiedlich ist hier lediglich der Verlauf der Unterdruckleitung 13 und der Bypassleitung 17, die eine Ausbildung des Magnetventils 18 als Dreiwegeventil erfordern.Only the course of the vacuum line is slightly different here 13 and the bypass line 17, which a design of the solenoid valve 18 as a three-way valve require.

Die Bedieneinheit 9 kann dabei als z.B. versteckt in oder am Fahrzeug angeordneter mechanischer, z.B. schlüsselbetätigter Schalter ausgebildet sein oder sie kann beispielsweise durch Eingabe eines Zahlencodesaktiviert werden. Sie kann aber auch beispielsweise als Sender ausgebildet sein und ihre Verbindung mit dem Magnetventil kann über ein Lichtleitkabel erfolgen.The operating unit 9 can be hidden in or on the vehicle, for example arranged mechanical, e.g. key-operated switch or it can be activated, for example, by entering a numeric code. she can but also be designed, for example, as a transmitter and its connection with the Solenoid valve can be done via a fiber optic cable.
