Description

Kraftfahrzeug Die Erfindung bezieht sich auf ein Kraftfahrzeug oit einer Brannkraftmaschine, die in einem geschlossenen Teil des Kraftfahrzeugs angeordnet ist, der einen regelbaren Kühlluftzuf2hrungskanal und einen Kühlluftabführungskenal aufweist. Motor vehicle The invention relates to a motor vehicle oit an internal combustion engine, which is arranged in a closed part of the motor vehicle is, which has a controllable cooling air supply duct and a cooling air discharge bar having.

Ein derartiges Kraftfahrzeug ist durch die DX-PS 576 741 bekannt. Dabei wird zur Vermeidung einer Überkühlung der Brennkraftmaschine der Kühllnftzustrom gedrosselt und ein Teil der erwärmten Kühlluft durch eine Kurzschlußleitung zur Saugseite des Kühlluftgebläses zurückgeführt.Such a motor vehicle is known from DX-PS 576 741. In this case, the cooling air inflow is used to avoid overcooling of the internal combustion engine throttled and part of the heated cooling air through a short-circuit line to Recirculated suction side of the cooling air fan.

Ferner sind Isoliermaßnahmen bekannt, z.B. Wattierung der Motorhaub und Kühlerjalousien, die eine schnelle Abkühlung der Brennkraftmaschine verbindern, jedoch blieb die Unterseite des Einbauraumes offen bzw. es fehlte eine Isolierung, so daß insbesonders bei Wind viel Wärme konvektiv verlorengeht.Insulation measures are also known, e.g. padding the engine hood and radiator shutters, which combine rapid cooling of the internal combustion engine, however, the underside of the installation space remained open or insulation was missing, so that a lot of heat is lost by convection, especially when there is wind.

Der erfindung liegt die Aufgabe zugrunde, die. Brennkraftmaschine dei Fahrzeugs während kleiner 3etriebspausawarzuhalten, um die Betrietsphasen mit su kalter Brennnraftmaschine absukürsen. Diese Aufgabe wird erfindungsgemäß bei einem Fahrzeug der eingangs beschriebenen Art dadurch gelöst, daB der geschlossene Teil wärme isoliert ist und der Kühlluftzuführungskanal mit Einschalten einen Betriebsstromkreises in Abhängigkeit der Brennkraftmaschinentemperatur selbsttätig mehr oder weniger geöffnet ist.The invention is based on the task. Internal combustion engine The vehicle was to be kept during small pauses in operation in order to keep track of the operating phases absukürsen su cold internal combustion engine. According to the invention, this object is achieved in a vehicle of the type described at the outset in that the closed Part is heat insulated and the cooling air supply duct with switching on an operating circuit more or less automatically depending on the internal combustion engine temperature is open.

Dadurch wird erreicht, daß bei geschlossenem Kühlluftzuführungskanal die konvektive Wärmeabfuhr äußerst gering ist, was für kaltstart und Fahrpausen wichtig ist. Bei geöffnetem Kühlluftzuführungskanal Jedoch ist die Wärmeabfuhr auch für sommerlichen Fahrbetrieb gewährleistet, insbesondere wenn gemäß einer Ausgestaltung der Erfindung in einfacher Weise die untere Seite des geschlossenen Teils durch eins Isolierschale gebildet wird, die auf Längsrippen der Ölwanne der Brennkraftmaschine befestigt ist, da die Verrippung der Unterseite die Abstrahlungsbehinderung kompensiert.This ensures that when the cooling air supply duct is closed The convective heat dissipation is extremely low, which is good for cold starts and driving breaks important is. When the cooling air supply duct is open, however, the heat is also dissipated Guaranteed for summer driving, especially if according to one embodiment of the invention in a simple manner through the lower side of the closed part an insulating shell is formed on the longitudinal ribs of the oil pan of the internal combustion engine is attached, as the ribbing on the underside compensates for the radiation obstruction.

Wichtigstes Ziel der Erfindung ist, die Betriebsphasen mit kaltem Triebwerk Abzukürzen und damit einen Beitrag zur Verminderung der Abgalanteile an Kohlenmonoxid und teilreagierten Kohlenwasserstoffen zu liesten. Eine Minderung des Kraftstoffverbrauchs und dee Brennkraftmaschinenverschleißes ist eine weitere Folge.The main aim of the invention is to reduce the operating phases with cold Shorten the engine and thus contribute to reducing the amount of waste To dissolve carbon monoxide and partially reacted hydrocarbons. A reduction fuel consumption and engine wear is another Episode.

Die Regelung des Kühlluftzuführungskanals geschieht duroh Thermostat. Bei Ausschalten des Betriebstromkreises wird Jedoch ohne Rücksicht auf die Thermostatstellung der tUhlluftzuführungskanal geschlossen.The regulation of the cooling air supply channel is done by thermostat. When the operating circuit is switched off, however, the thermostat setting is not taken into account the tUhlluftzuführungskanal closed.

Ferner kann es zweckmäßig sein, durch an einer Haube des geschlossenen Teils angebrachte isolierende Formstücke die Ionturen der Brennkraftmaschine so einzuhüllen, daß eine gute Kühlluftführung gewährleistet ist.It may also be useful to close the hood on a hood Partly attached insulating fittings the Ionturen of the internal combustion engine so envelop that a good cooling air flow is guaranteed.

Gemäß einer weiteren Ausgestaltung der Erfindung wird vorgeschlagen, daß ein Teil der Ktlhlluft in Hohlräume des Fahrzeuge geleitet wird. Außer der Wärmespeicherwirkung erzielt man dadurch eine gute Belüftung und Trocknung dieser Räume, wodurch Korrosion vermieden wird.According to a further embodiment of the invention, it is proposed that that part of the cooling air is directed into cavities in the vehicle. Besides the heat storage effect this achieves good ventilation and drying of these rooms, which leads to corrosion is avoided.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.An exemplary embodiment of the invention is shown in the drawing.

In einem Kraftfahrzeug 1 ist in einem geschlossenen Teil 2 mit einem regelbaren Kühlluftzuführungskanal 3 und einem Kühlluftabführungskanal 4 eine Brennkraftmaschine 5 angeordnet. Die Regelung der Kühlluftzuführung erfolgt mit Einschalten des Betriebestromikreises in Abhängigkeit der Brennkraftmaschinentsmperatar selbsttätig durch Klappen oder eine Jalousie 6. Während die untere Seite dsa geschlossenen Teils 2 durch eine Isolierschale 7 gebildet wird, die auf Längerippen 10 einer Ölwenne 11 der Brenkkraftmaschine 5 befestigt ist, sind an der oberen Seite isolierende Poristücke 8 an einer Haube 9 vorgesehen.In a motor vehicle 1 is in a closed part 2 with a controllable cooling air supply duct 3 and a cooling air discharge duct 4 an internal combustion engine 5 arranged. The cooling air supply is regulated when the operating circuit is switched on depending on the internal combustion engine automatically by flaps or a blind 6. While the lower side of the closed part 2 by an insulating shell 7 is formed on the longitudinal ribs 10 of an oil pan 11 of the internal combustion engine 5 is attached, insulating porous pieces 8 are on a hood on the upper side 9 provided.
