Abstract

The vehicle has two tanks for heavy and lighter evaporating fuels, and a fuel supply line with a switchable valve that supplies fuel to a self-ignition internal-combustion engine in two positions. A comparison circuit compares distance between the respective position of the vehicle determined by a global positioning system (GPS) and a predetermined position, and causes switching of the valve during exceedance and/or falling below of the distance.

Description

Die Erfindung betrifft ein Fahrzeug mit selbst zündender Brennkraftmaschine, die mit einem ersten Tank für einen schwerer verdampfenden Kraftstoff, einem zweiten Tank für einen leichter verdampfenden Kraftstoff und einer Kraftstoffzuleitung mit einem in einer ersten Stellung die Brennkraftmaschine mit dem ersten Kraftstoff mit einer zweiten Stellung die Brennkraftmaschine mit dem zweiten Brennstoff versorgenden schaltbaren Ventil.The The invention relates to a vehicle with a self-igniting internal combustion engine, with a first tank for a heavier-evaporating fuel, a second tank for one easier evaporating fuel and a fuel supply line with a in a first position, the internal combustion engine with the first fuel with a second position, the internal combustion engine with the second fuel supplying switchable valve.

Fahrzeuge, die mit Pflanzenöl betrieben werden können, erfreuen sich zunehmender Beliebtheit. Bei ihnen stellt sich allerdings das Problem, dass das Pflanzenöl erst bei erreichen höherer Temperaturen ausreichend verdampft. Aus diesem Grund werden die Fahrzeuge mit einem weiteren, mit Dieselkraftstoff gefüllten Tank versehen, wobei der Dieselkraftstoff bei kaltem Motor verwendet wird. Über ein manuell oder aber bei Erreichen einer ausreichenden Temperatur geschaltetes Ventil wird die Brennkraftmaschine dann auf den Dieselkraftstoff umgestellt. Es wird in soweit auf die DE 198 23 335 A1 verwiesen.Vehicles that can be operated with vegetable oil are enjoying increasing popularity. With them, however, the problem arises that the vegetable oil evaporates sufficiently only when it reaches higher temperatures. For this reason, the vehicles are provided with another tank filled with diesel fuel, with the diesel fuel being used when the engine is cold. The internal combustion engine is then switched to the diesel fuel via a valve that is switched manually or when a sufficient temperature is reached. It will be in so far on the DE 198 23 335 A1 directed.

Dabei stellt sich allerdings das Problem, dass vor Erreichen des Ortes, an dem das Fahrzeug abgestellt werden soll, die Umschaltung des Ventils auf Dieselkraftstoff bewirkt werden soll, damit die Kraftstoffzuleitung bei einem erneuten Inbetriebsetzen des Fahrzeugs nicht mit Pflanzenöl gefüllt ist: In diesem Fall ist eine Spülung erforderlich, bei dem das Pflanzenöl ausgespült und durch Dieselkraftstoff ersetzt wird.there However, the problem arises that before reaching the place, where the vehicle is to be parked, the switching of Valve on diesel fuel should be effected so that the fuel supply line when restarting the vehicle is not filled with vegetable oil: In this case is a conditioner required in which the vegetable oil rinsed out and by diesel fuel is replaced.

Es stellt sich dabei das Problem, dass ein derartiges Spülen immer dann erforderlich ist, wenn der Fahrer es vergisst, rechtzeitig von dem Betrieb mit Pflanzenöl auf den Betrieb mit Dieselkraftstoff umzustellen.It There is the problem that such a rinse always then required, if the driver forgets it, on time from the operation with vegetable oil to switch to operation with diesel fuel.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Fahrzeug der eingangs genannten Art zu schaffen, bei der auch dann, wenn der Fahrer nicht aufmerksam ist, das Umschalten auf Dieselkraftstoff vor Erreichen des Ortes, an dem das Fahrzeug abgestellt werden soll, bewirkt wird.Of the Invention is therefore the object of a vehicle of the beginning in which even if the driver is not attentive is switching to diesel fuel before reaching the place at which the vehicle is to be parked, is effected.

Erfindungsgemäß wird diese Aufgabe gelöst durch ein GPS und einer Vergleichsschaltung, die die Distanz zwischen der anhand des GPS ermittelten jeweiligen Position des Fahrzeugs und wenigstens einem vorgegebenen Ort vergleicht und bei Unter- und/oder Überschreiten einer vorgegebenen Distanz das Umschalten des Ventils bewirkt.According to the invention this Task solved by a GPS and a comparison circuit showing the distance between the determined by the GPS respective position of the vehicle and compares at least one given location and undershooting and / or crossing a predetermined distance causes the switching of the valve.

Die Vergleichsschaltung ist vorzugsweise zur Speicherung einer Mehrzahl von Orten eingerichtet.The Comparing circuit is preferably for storing a plurality set up by places.

Die Erfindung macht sich also den Umstand zunutze, dass derartige Fahrzeuge regelmäßig an vorgegebenen Orten abgestellt werden, bevorzugt dem Betriebshof. Nach der Erfindung wird dieser Ort in ein im Fahrzeug ohnehin befindliches GPS (Global Positioning System) eingegeben. Eine Vergleichsschaltung vergleicht die jeweiligen von GPS festgestellte Position des Fahrzeugs dem in die Vergleichsschaltung eingegebenen Ort und bewirkt bei Unter- und/oder Überschreiten einer vorgegebenen Distanz das Umschalten des Ventils. Auf diese Weise ist es möglich, dass – beispielsweise ein Kilometer vor Erreichen des Betriebshofs – ein automatisches Umschalten der Brennkraftmaschine mit dem schwerer verdampfenden Kraftstoff auf einen Betrieb mit dem leichter verdampfenden Kraftstoff umgestellt wird, die Kraftstoffleitung ist in diesem Fall bei Abstellen und erneutem Starten des Fahrzeugs mit dem leichter verdampfenden Kraftstoff gefüllt, ein aufwendiges Spülen ist nicht erforderlich.The Invention makes use of the fact that such vehicles regularly at predetermined Places are parked, preferably the depot. After the invention This location is in a vehicle already in the GPS (Global Positioning System). A comparator compares the respective ones GPS position of the vehicle detected in the comparison circuit entered place and causes in case of under- and / or exceeding a predetermined distance, the switching of the valve. To this Way is it possible that - for example one kilometer before reaching the depot - automatic switching the internal combustion engine with the less volatile fuel switched to operation with the more easily evaporating fuel In this case, the fuel line is at stop and again Starting the vehicle with the more easily evaporating fuel filled, a complex rinse not necessary.

Es ist nun möglich in die Vergleichsschaltung eine Mehrzahl von Orten einzugeben, beispielsweise den Orten einer Mehrzahl von Betriebshöfen oder den üblichen Rastplätzen oder Zielorten.It is now possible to enter into the comparison circuit a plurality of locations, for example the Locate a plurality of depots or the usual rest areas or destinations.

Bei der vorgeschlagenen Ausbildung eines Fahrzeugs ist es auch möglich, automatisch ein Umschalten von dem für den Start verwendeten leichter verdampfenden Kraftstoff auf den schwerer verdampfenden Kraftstoff dann automatisch zu bewirken, wenn das Fahrzeug sich von dem Betriebshof, dessen Ort in die Vergleichsschaltung eingegeben worden ist, um eine vorgegebene Distanz, beispielsweise also ein Kilometer, Entfernung.at The proposed training of a vehicle, it is also possible automatically a switch from the for the start used more easily evaporating fuel on the then to automatically effect heavier evaporating fuel when the vehicle moves from the depot, whose place is in the comparison circuit has been entered by a predetermined distance, for example one kilometer, distance.
