Abstract
Beschrieben wird ein Verfahren zum Betreiben eines Verdampfers für Flüssiggas in einem Kraftfahrzeug, das einen Benzintank und einen Flüssiggastank aufweist, wobei Flüssiggas in einem Verdampfungsraum verdampft wird, der mit einem zweiten Raum (1), der durch Einleiten von Kühlwasser eines Verbrennungsmotors beheizbar ist, einen Wärmetauscher bildet. Erfindungsgemäß ist vorgesehen, dass in einem ersten Betriebszustand der Verdampfer mit einer elektrischen Heizung (5) beheizt und ein Kühlwasserstrom (10) mit einer Bypassleitung (2) an dem zweiten Raum (1) vorbeigeführt wird, und in einem zweiten Betriebszustand des Verdampfers ein Kühlwasserstrom (10) durch den zweiten Raum (1) geleitet wird. Die Erfindung betrifft ferner einen Kraftstoffverdampfer für ein mit Flüssiggas betriebenes Kraftfahrzeug.A method is described for operating an evaporator for liquid gas in a motor vehicle, which has a gasoline tank and a liquid gas tank, liquid gas being evaporated in an evaporation chamber which is connected to a second chamber (1) which can be heated by introducing cooling water from an internal combustion engine Forms heat exchanger. According to the invention it is provided that in a first operating state the evaporator is heated with an electric heater (5) and a cooling water flow (10) with a bypass line (2) is led past the second space (1), and in a second operating state of the evaporator a cooling water flow (10) is passed through the second room (1). The invention also relates to a fuel vaporizer for a motor vehicle operated with liquid gas.
Description
Die Erfindung geht aus von einem Verfahren zum Betreiben eines Verdampfers für Flüssiggas mit den im Oberbegriff des Anspruchs 1 angegebenen Merkmalen sowie einem Kraftstoffverdampfer gemäß dem Oberbegriff des Anspruchs 3.The invention is based on a method for operating an evaporator for liquefied petroleum gas having the features specified in the preamble of
Für Kraftfahrzeuge verwendetes Flüssiggas wird häufig auch als Autogas oder LPG (liquified Petroleum gas) bezeichnet. Damit betriebene Kraftfahrzeuge haben in der Regel einen Benzintank zusätzlich zu einem Flüssiggastank, so dass der Verbrennungsmotor des Fahrzeugs wahlweise mit Flüssiggas oder Benzin betrieben werden kann. Das im Flüssiggastank unter Druck befindliche Flüssiggas wird dem Verbrennungsmotor über einen Verdampfer und Druckregler gasförmig zugeführt. Da das Gas beim Verdampfen stark abkühlt, wird der Verdampfer mit Kühlwasser des Verbrennungsmotors beheizt.Liquefied petroleum gas used for motor vehicles is often referred to as liquefied petroleum gas (LPG) or LPG (liquefied petroleum gas). Vehicles powered thereby typically have a fuel tank in addition to a liquefied gas tank so that the vehicle's internal combustion engine can be selectively operated with LPG or gasoline. The liquid gas under pressure in the liquefied gas tank is supplied to the internal combustion engine via an evaporator and pressure regulator in gaseous form. Since the gas cools strongly during evaporation, the evaporator is heated with cooling water of the internal combustion engine.
Üblicherweise werden derartige Kraftfahrzeuge bei Fahrtbeginn zunächst mit Benzin betrieben und schalten erst zu einem späteren Zeitpunkt auf Flüssiggasbetrieb um, wenn sich das Kühlwasser erwärmt hat.Usually, such vehicles are initially operated with gasoline at the start of the journey and switch to LPG operation only at a later time when the cooling water has warmed up.
Flüssiggas ist deutlich kostengünstiger als Benzin und verbrennt schadstoffärmer. Dies gilt insbesondere für verbrauchsintensive Kaltlaufphasen des Motors.LPG is significantly cheaper than gasoline and burns less polluting. This applies in particular to consumption-intensive cold running phases of the engine.
Aufgabe der vorliegenden Erfindung ist es deshalb, einen Weg aufzuzeigen, wie die Vorteile von Flüssiggas als Kraftstoff für Fahrzeuge noch besser genutzt werden können.Object of the present invention is therefore to show a way how the benefits of LPG can be used even better as fuel for vehicles.
Diese Aufgabe wird erfindungsgemäß durch ein Verfahren mit den im Anspruch 1 angegebenen Merkmalen sowie einen Kraftstoffverdampfer gemäß Anspruch 3 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand von Unteransprüchen.This object is achieved by a method having the features specified in
Erfindungsgemäß kann der im normalen Betrieb zum Beheizen einer Verdampferkammer verwendete Kühlwasserstrom mit einer Bypassleitung umgeleitet und ein in dem Verdampfer eingeschlossenes Wasservolumen elektrisch beheizt werden. Auf diese Weise kann der Verdampfer auch bei kaltem Motor betrieben werden und ein Fahrzeug deshalb schon zu einem früheren Zeitpunkt vom Benzinbetrieb auf Flüssiggasbetrieb umgeschaltet oder der Motor sogar mit Flüssiggas gestartet werden.According to the invention, the cooling water flow used for heating an evaporator chamber during normal operation can be diverted with a bypass line and a water volume trapped in the evaporator can be electrically heated. In this way, the evaporator can be operated even when the engine is cold and a vehicle therefore already switched from gasoline operation to liquefied gas operation at an earlier time or the engine can even be started with liquefied gas.
Bevorzugt wird bei einem erfindungsgemäßen Verfahren die Temperatur des Kühlwasserstroms überwacht und als Kriterium für das Umschalten zwischen den beiden Betriebszuständen des Verdampfers verwendet. Anstatt in den Normalbetrieb, in dem die Verdampferkammer durch einen vom Motor erwärmten Kühlwasserstrom beheizt wird, umzuschalten, sobald die Kühlwasser- oder Motortemperatur einen vorgegebenen Schwellenwert übersteigt, ist es auch möglich in den Normalbetrieb dann umzuschalten, wenn seit dem Motorstart eine vorgegebene Zeitspanne vergangen ist.Preferably, in a method according to the invention, the temperature of the cooling water flow is monitored and used as a criterion for the switching between the two operating states of the evaporator. Instead of switching to normal operation in which the evaporator chamber is heated by a motor water heated cooling water flow, as soon as the cooling water or engine temperature exceeds a predetermined threshold, it is also possible to switch to normal operation when a predetermined time has elapsed since the engine started ,
Bei einem erfindungsgemäßen Kraftstoffverdampfer kann ein Abschnitt einer Kühlwasserleitung, die zusammen mit einem Verdampfungsraum einen Wärmetauscher bildet, mit einem Umschaltventil von einem Kühlwasserstrom abgekoppelt und der Kühlwasserstrom auf eine Bypassleitung umgeleitet werden. Der mit dem Umschaltventil abkoppelbare Teil des Kühlwassersystems bildet einen zweiten Raum des Kraftstoffverdampfers. In diesem zweiten Raum ist eine elektrische Heizung angeordnet, so dass darin enthaltenes Wasser bei Bedarf beheizt werden kann, um den Verdampfer auch bei kaltem Kühlwasser betreiben zu können.In a fuel vaporizer according to the invention, a section of a cooling water line, which forms a heat exchanger together with an evaporation space, can be decoupled from a cooling water flow with a switching valve and the cooling water flow can be diverted to a bypass line. The decoupled with the switching valve part of the cooling water system forms a second space of the fuel evaporator. In this second room, an electric heater is arranged so that water contained therein can be heated if necessary to operate the evaporator even with cold cooling water can.
