Description

Die Erfindung bezieht sich auf ein Kraftfahrzeug entsprechend dem Oberbegriff des Anspruchs 1.The invention relates accordingly to a motor vehicle the preamble of claim 1.

Gesetzliche Bestimmungen schreiben vor, daß Kraftstoffdämpfe aus dem Kraftstoffbehälter nicht in die Atmosphäre entlassen werden dürfen. Zur Erfüllung dieser Bestimmungen werden die Kraftstoffdämpfe über einen sogenannten Kanister, der im allgemeinen Aktivkohle als Filtermaterial enthält, dem An­ saugsystem der Brennkraftmaschine zugeführt. Dieser Filter fängt in erster Linie die beim Stillstand des Kraftfahrzeuges entstehenden Kraftstoffdämpfe auf und wird dadurch regene­ riert, daß im Betrieb Luft aus der Atmosphäre durch den Filter hindurch angesaugt wird. Die Regeneration des Filters wird durch Erwärmen des Filters verbessert und beschleunigt. Es ist bekannt, zu diesem Zweck elektrische Heizeinrichtungen vorzusehen oder die Luft, die durch den Filter angesaugt wird, aus dem Motorraum von einer Stelle nahe dem Auspuffsy­ stem der Brennkraftmaschine zu nehmen. Die Unterbringung des Kanisters im Motorraum bereitet jedoch aufgrund der beengten Platzverhältnisse erhebliche Probleme. Man ist daher dazu übergegangen, den Kanister an einer anderen Stelle im Kraft­ fahrzeug, beispielsweise in der Reserveradmulde anzuordnen. Hier ist jedoch die zur Beschleunigung der Regeneration er­ wünschte Erwärmung des Kanisters nur mit einer verhältnis­ mäßig aufwendigen elektrischen Heizvorrichtung möglich.Legal regulations require that fuel vapors do not release into the atmosphere from the fuel tank may be. To comply with these provisions, the Fuel vapors through a so-called canister, which in the contains general activated carbon as filter material, the An suction system of the internal combustion engine supplied. This filter primarily catches when the motor vehicle is at a standstill resulting fuel vapors and is thereby rain riert that in operation air from the atmosphere through the Filter is sucked through. The regeneration of the filter is improved and accelerated by heating the filter. It is known to use electric heaters for this purpose to provide or the air sucked in through the filter from the engine compartment from a location near the exhaust system stem of the internal combustion engine. The placement of the Canisters in the engine compartment are prepared due to the cramped conditions Space problems. One is therefore to it passed the canister at another location in the force to arrange vehicle, for example in the spare wheel well. However, here is the one to accelerate regeneration only wanted to warm the canister with a ratio moderately complex electrical heater possible.

Der Erfindung liegt die Aufgabe zugrunde, ein Kraftfahrzeug der gattungsgemäßen Art zu schaffen, bei dem einerseits eine Erwärmung des Kanisters ohne zusätzliche Bauteile stattfindet und andererseits das Entstehen von Kraftstoffdämpfen im Kraftstoffbehälter verringert ist.The invention has for its object a motor vehicle  to create the generic type, in which on the one hand The canister is heated without additional components and on the other hand the generation of fuel vapors in the Fuel tank is reduced.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Kanister zwischen dem Auspuffsystem und dem Kraftstoffbehäl­ ter angeordnet ist.This object is achieved in that the Canister between the exhaust system and the fuel tank ter is arranged.

Bei dem erfindungsgemäßen Vorschlag erfolgt einerseits eine Aufheizung des Kanisters durch die Strahlungswärme des Aus­ puffsystems und andererseits eine Wärmeisolierung des Kraft­ stofftanks durch den Kanister gegenüber der Strahlungswärme des Auspuffsystems, wodurch das Entstehen von Kraftstoff­ dämpfen im Kraftstoffbehälter verringert wird.In the proposal according to the invention, on the one hand Heating of the canister by the radiant heat of the off puff systems and on the other hand thermal insulation of the force cloth tanks through the canister against the radiant heat of the exhaust system, causing the generation of fuel steam in the fuel tank is reduced.

Der Kraftstoffbehälter kann auf einer dem Auspuffsystem zuge­ wandten Seite eine Einbuchtung aufweisen, in welcher der Kanister angeordnet ist. Dadurch wird die Unterbringung des Kanisters erleichtert.The fuel tank can on one of the exhaust system facing side have an indentation in which the Canister is arranged. This will accommodate the Canisters relieved.

Weist der Kraftstoffbehälter zwei beabstandete Abschnitte auf, zwischen denen sich das Auspuffsystem erstreckt, so sollte zwischen jedem Behälterabschnitt und dem Auspuffsystem ein Kanister angeordnet werden.The fuel tank has two spaced sections on, between which the exhaust system extends, so should be between each section of the tank and the exhaust system a canister can be arranged.

Ein Ausführungsbeispiel der Erfindung wird im folgenden unter Bezugnahme auf die Zeichnungen beschrieben. Es zeigt:An embodiment of the invention is described below Described with reference to the drawings. It shows:

Fig. 1 eine Draufsicht eines Fahrwerks eines Kraftfahrzeuges in schematischer Darstellung, Fig. 1 is a plan view of a chassis of a motor vehicle in a schematic representation;

Fig. 2 eine Ansicht in Richtung des Pfeiles II in Fig. 1, und Fig. 2 is a view in the direction of arrow II in Fig. 1, and

Fig. 3 eine Draufsicht eines anders ausgebildeten Kraftstoff­ behälters. Fig. 3 is a plan view of a differently designed fuel container.

Das in Fig. 1 schematisch dargestellte Kraftfahrzeug wird von einer Brennkraftmaschine 1 angetrieben, die ein Ansaugsystem 2 und ein Auspuffsystem 3 mit einem Auspuffkrümmer 4, einem Auspuffrohr 5, einem Vorschalldämpfer 6 und einem Haupt­ schalldämpfer 7 aufweist. Mit 8 ist der Kraftstoffbehälter bezeichnet, der einen Einfüllstutzen mit Tankverschlußdeckel aufweist.The vehicle shown schematically in Fig. 1 is driven by an internal combustion engine 1 , which has an intake system 2 and an exhaust system 3 with an exhaust manifold 4 , an exhaust pipe 5 , a front silencer 6 and a main silencer 7 . With 8 the fuel tank is designated, which has a filler neck with a filler cap.

Das Kraftfahrzeug ist mit einer Anlage zum Auffangen von aus dem Kraftstoffbehälter 8 entweichenden Kraftstoffdämpfen versehen. Diese Anlage weist einen Kanister 9 mit einem Ak­ tivkohlefilter auf, dessen eine Seite mit der Atmosphäre in Verbindung ist und dessen andere Seite einerseits über eine Leitung 10 mit dem Kraftstoffbehälter 8 und andererseits über eine Leitung 11 mit dem Ansaugsystem 2 der Brennkraftmaschine 1 verbunden ist.The motor vehicle is provided with a system for collecting fuel vapors escaping from the fuel tank 8 . This system has a canister 9 with an active carbon filter, one side of which is connected to the atmosphere and the other side of which is connected on the one hand via a line 10 to the fuel tank 8 and on the other hand via a line 11 to the intake system 2 of the internal combustion engine 1 .

Da bei Kraftfahrzeugen der Kraftstoffbehälter in der Regel im hinteren Abschnitt des Kraftfahrzeuges angeordnet und das Auspuffsystem nach hinten geführt ist, ergibt sich zwangsläu­ fig, daß das Auspuffsystem nahe an dem Kraftstoffbehälter vorbeigeführt ist. Dies hat eine Erwärmung des Kraftstoffbe­ hälters durch die Strahlungswärme des Auspuffsystems zur Folge, die zu einer verstärkten Bildung von Kraftstoffdämpfen im Kraftstoffbehälter führt. Dies bedingt wiederum einen entsprechend großen Kanister, um diese Kraftstoffdämpfe mög­ lichst vollständig absorbieren zu können. Bei dem erfindungs­ gemäßen Vorschlag wird die Erwärmung des Kraftstoffbehälters und des Inhalts desselben durch die Strahlungswärme des Aus­ puffsystems dadurch erheblich verringert, daß der Kanister 9 zwischen dem Kraftstoffbehälter 8 und dem Auspuffrohr 9 ange­ ordnet ist. Diese Anordnung führt gleichzeitig zu einer er­ wünschten Erwärmung des Kanisters 9, durch welche die Rege­ neration des Aktivkohlefilters beschleunigt wird. Since in motor vehicles the fuel tank is usually arranged in the rear section of the motor vehicle and the exhaust system is guided to the rear, it inevitably results that the exhaust system is guided close to the fuel tank. This results in the fuel tank being heated by the radiant heat of the exhaust system, which leads to an increased formation of fuel vapors in the fuel tank. This in turn requires a correspondingly large canister in order to be able to absorb these fuel vapors as completely as possible. In the fiction, contemporary proposal, the heating of the fuel tank and the content of the same by the radiant heat of the exhaust system is significantly reduced by the fact that the canister 9 is arranged between the fuel tank 8 and the exhaust pipe 9 . This arrangement also leads to a desired heating of the canister 9 , through which the regeneration of the activated carbon filter is accelerated.

Um auch einen relativ großen Kanister möglichst platzsparend unterbringen zu können, ist der Kraftstoffbehälter 8 auf seiner dem Auspuffrohr 5 zugewandten Seite mit einer Einbuch­ tung 12 versehen, in welcher der Kanister 9 angeordnet ist.In order to accommodate a relatively large canister as space-saving as possible, the fuel tank 8 is provided on its side facing the exhaust pipe 5 with a registration device 12 , in which the canister 9 is arranged.

In Fig. 3 ist in Draufsicht ein Kraftstoffbehälter 8′ darge­ stellt, der zwei beabstandete Abschnitte 13 aufweist, zwi­ schen denen der Vorschalldämpfer 6′ des Auspuffsystems der Brennkraftmaschine angeordnet ist. Analog zu der Ausführung gemäß Fig. 1 und 2 ist zwischen dem Vorschalldämpfer 6′ und jedem Behälterabschnitt 13 ein Kanister 9, angeordnet, der die Strahlungswärme des Vorschalldämpfers 6′ von den Behäl­ terabschnitten 13 weitgehend fernhält, jedoch selbst aufgeheizt wird.In Fig. 3 is a top view of a fuel tank 8 'Darge, which has two spaced sections 13 , between which the front silencer 6 ' of the exhaust system of the internal combustion engine is arranged. Analogous to the embodiment according to FIGS. 1 and 2, a canister 9 is arranged between the front silencer 6 'and each container section 13 , which largely keeps the radiant heat of the front silencer 6 ' from the container ter section 13 , but is itself heated.
