Abstract

At extremely low temperatures, diesel fuel solidifies. In order to prevent this, a 12 volt heating rod is incorporated in the metal mass of the filter head, which rod switches on at plus 6 DEG C and is automatically switched off by a thermostat at a fuel temperature of 50 DEG C. Since the fuel consumption in diesel trucks is significantly greater than in passenger vehicles, the fuel preheater for these motor vehicles, which generally have a long fuel line, is mounted on the fuel tank. In addition a second heating system with a low wattage is integrated in the fuel filter for stationary periods in order to guard against solidification of the fuel even on cold nights.

Description

Abb. 1 zeigt die Draufsicht auf einen Filterkopf mit quer eingesetztem 12-Volt-Heizstab (2) für die Fahrtheizung und stehendem Heizstab (4) für die Nachtheizung. Fig. 1 shows the top view of a filter head with a transverse 12-volt heating element ( 2 ) for the travel heater and a standing heating element ( 4 ) for the night heating.

Abb. 2 zeigt Schnitt durch den Diesel-Filterkopf mit isolierter Schutzhülse und Kopf­ deckel und den beiden Heizstäben (2+4) Fig. 2 shows a section through the diesel filter head with insulated protective sleeve and head cover and the two heating elements ( 2 + 4 )

Abb. 3 zeigt Schnitt durch den Kraftstoff-Vorwärmer für Lastfahrzeuge auf den Kraftstofftank montiert, mit den beiden Heizstäben (2+4) Fig. 3 shows a section through the fuel preheater for trucks mounted on the fuel tank, with the two heating elements ( 2 + 4 )

Abb. 4 zeigt Schnitt durch einen Kraftstoff-Vorwärmer geänderter Bauart, ähnlich wie bei Abb. 3 mit den beiden Heizstäben (2+4) Fig. 4 shows a section through a modified fuel preheater, similar to Fig. 3 with the two heating elements ( 2 + 4 )

Abb. 5 zeigt Draufsicht auf einen Doppelfilter mit querliegendem Heizstab (2) Fig. 5 shows a top view of a double filter with a transverse heating element ( 2 )

Abb. 6 zeigt Schnitt durch einen Doppelfilter mit Heiz­ stab (2) und stehendem Heizstab (4) für die Nachtheizung. Fig. 6 shows a section through a double filter with heating rod ( 2 ) and standing heating rod ( 4 ) for night heating.

Wie bei Abb. 1 ersichtlich, ist der 12-Volt-Heizstab (2) horizontal im Filterkopfmaterial (7) eingesetzt und hat keine direkte Verbindung mit dem Dieseltreibstoff, wo­ durch eine hohe Betriebssicherheit gewährleistet wird.As can be seen in Fig. 1, the 12-volt heating element ( 2 ) is inserted horizontally in the filter head material ( 7 ) and has no direct connection to the diesel fuel, which ensures high operational reliability.

Abb. 2 zeigt die kompakte Anordnung des 12-Volt-Heiz­ stabes (2) im Filterkopfkern (7) mit dem Thermostat (3), der Stromzuleitung (5), sowie die Anordnung der Isolier­ schutzhülse (10) mit Kopfdeckel (11) am Treibstoffilter (1). Fig. 2 shows the compact arrangement of the 12-volt heating rod ( 2 ) in the filter head core ( 7 ) with the thermostat ( 3 ), the power cable ( 5 ), and the arrangement of the insulating sleeve ( 10 ) with head cover ( 11 ) on Fuel filter ( 1 ).

Bei Abb. 3 ist der Diesel-Treibstoffvorwärmer am Treib­ stofftank (14) montiert. Diese Ausführungsart ist speziell für Lastfahrzeuge vorgesehen, weil die langen Treib­ stoffleitungen bis zum Filter (1) zum vorzeitigen Ver­ sulzen neigen.In Fig. 3, the diesel fuel preheater is mounted on the fuel tank ( 14 ). This type of design is specially designed for trucks because the long fuel lines up to the filter ( 1 ) tend to sulzen prematurely.

Dieser Treibstoffvorwärmer (1) ist speziell als Wärme­ boiler gedacht und hält ständig eine gewisse Menge Diesel- Treibstoff auf etwa 30° Cels. warm, so daß ein Versulzen der Treibstoffleitungen exakt verhindert wird.This fuel preheater ( 1 ) is specially designed as a heat boiler and constantly holds a certain amount of diesel fuel at around 30 ° Cels. warm, so that the fuel lines do not become clogged.

Die Heizleistung des 12-Volt-Heizstabes (2) ist der Motoren­ größe angepaßt und ist ebenfalls im Materialkern des Vor­ wärmers integriert, wodurch eine große und absolut un­ fallsichere Beheizung des Kraftstoff-Vorwärmers erreicht wird.The heating power of the 12-volt heating element ( 2 ) is adapted to the size of the engine and is also integrated in the material core of the pre-heater, whereby a large and absolutely un fail-safe heating of the fuel preheater is achieved.

Ein zweiter Heizstab (4) dient als Standzeit-Beheizung und hat nur wenige Watt Heizleistung, um den Diesel­ filter auch in kalten Nächten warmzuhalten. Diese Anordnung gilt auch für Doppelfilter, welche auf der Zeichnung 5 und 6 als Durchlauferhitzer mit dem Heizstab (2) veranschau­ licht ist. Der zweite Heizstab (4) mit geringerer Watt­ zahl dient als Nachtheizer, so daß auch beim Doppelfilter ein Versulzen in der Standzeit vermieden wird.A second heating element ( 4 ) is used to heat the tool life and has only a few watts of heating power to keep the diesel filter warm even on cold nights. This arrangement also applies to double filters, which is illustrated in the drawing 5 and 6 as a water heater with the heating element ( 2 ). The second heating element ( 4 ) with a lower wattage serves as a night heater, so that even with the double filter, staining during the service life is avoided.

Der neben dem Heizstab montierte Thermostat (3) reguliert exakt die vorgesehene Heizleistung und ein Isoliermantel aus Styropor (10) hält den Diesel-Treibstoff sehr lange warm und verhindert durch diese Isolation auch bei länge­ rer Standzeit des Fahrzeugs das Versulzen des Diesel- Treibstoffboilers.The thermostat ( 3 ) mounted next to the heating element precisely regulates the intended heating output and an insulating jacket made of styrofoam ( 10 ) keeps the diesel fuel warm for a very long time and, thanks to this insulation, prevents the diesel fuel boiler from becoming greasy even if the vehicle is not used for a long time.

Der Materialkern (13) des Vorwärmkopfteiles (7) ist mit Heizrippen (15) versehen, so daß der Heizstab (2) seine Heizwärme an eine große Heizfläche abführen kann, wo­ durch eine gleichmäßige Erwärmung des Diesel-Treibstoffes gewährleistet ist.The material core ( 13 ) of the preheating head part ( 7 ) is provided with heating fins ( 15 ), so that the heating element ( 2 ) can dissipate its heating energy to a large heating surface, which ensures uniform heating of the diesel fuel.
