Während der Arbeit der Verbrennungsmotoren werden erhebliche Mengen von für die Umwelt schädigenden Gasen ausgeworfen. Es sind katalytische Nachbrennungseinrichtungen bekannt, welche die Giftigkeit der Auspuffgase verringern. Diese Einrichtungen arbeiten wirksam nachdem eine entsprechend hohe Temperatur durch den Motor erreicht wird. Während des Anlaufs der Motoren ist die Zusammensetzung der Abgase besonders toxisch. Die Erwärmungszeit bei Kfz-Motoren dauert von einigen bis einigen Zehn Minuten. In dieser Zeit ist der Mittelstand der Verunreinigungen der Umwelt mit Auspuffgasen mehrfach von dem Stand der Verunreinigungen höher, die während einer stabilisierten Arbeit des Motors ausgeworfen werden, bei welcher die Auspuffgase zusätzlich auf einem Katalysator nachgereinigt werden können.During the work of the internal combustion engines significant amounts of environmentally harmful gases ejected. They are catalytic afterburners known which the toxicity of the exhaust gases reduce. These facilities operate effectively after a correspondingly high temperature is reached by the motor becomes. When the motors start up, the Exhaust gas composition particularly toxic. The warming time Motor vehicle engines last from a few to a few tens of minutes. At this time is the middle class pollution of the environment with exhaust gases several times from the level of contaminants higher during ejected from a stabilized work of the engine, where the exhaust gases are also on a Catalyst can be cleaned.

Zweck der Erfindung ist ein Verfahren zur Herabsetzung des Auswurfs der Auspuffgase während des Anlaufs des Motors und eine Vorrichtung zur Ausführung des Verfahrens zu schaffen.The purpose of the invention is a method of reduction exhaust gases are ejected during engine start-up and a device for carrying out the method create.

Das erfindungsgemäße Verfahren zur Herabsetzung des Auswurfs der Auspuffgase bei Motoren die mittels einer Flüssigkeit gekühlt werden beruht darauf, daß während des Anlaufs bis der Motor eine Temperatur seiner gewöhnlichen Arbeit erreicht, bei welcher die Temperatur des Kühlmittels des Motors To beträgt, wird das Kühlmittel mit Hilfe der Wärme der Verbrennungsgase erwärmt bis es eine Temperatur To ± 5°K erreicht und sodann wird die Erwärmung des Kühlmittels eingestellt und es wird gekühlt indem die Temperatur des Motors auf bekannte Weise aufrechterhalten wird.The inventive method for reducing the Ejection of exhaust gases on engines using a Liquid cooling is based on the fact that during the Start up until the motor reaches its normal temperature Work done at which the temperature of the coolant of the engine is To, the coolant is with Using the heat of the combustion gases warms it up Temperature To ± 5 ° K is reached and then the heating of the coolant and it is cooled by the Maintain engine temperature in a known manner becomes.

Das erfindungsgemäße Verfahren erlaubt es die Erwärmungszeit des Motors erheblich zu verkürzen, wodurch die Menge der toxischen Anlaufgase und somit ihre Gesamtmenge vermindert wird.The method according to the invention allows the heating time to shorten the engine considerably, thereby reducing the Amount of toxic start-up gases and thus their total amount is reduced.

Das Verfahren ist besonders von Bedeutung für eine spezifische Fahrt in Städten, welche durch einen großen Anteil von Anlaufzeiten während des Betriebs und ständige Untererwärmung des Motors gekennzeichnet ist.The procedure is particularly important for one specific driving in cities, which by a large Proportion of start-up times during operation and permanent Underheating of the engine is marked.

Die Vorrichtung zur Herabsetzung des Auswurfs der Verbrennungsgase bei Motoren, die mittels einem Kühlmittel gekühlt werden, bestehend aus Kühler, Pumpe und Thermostat, enthält ein Zweikanal-Auspuffsammelrohr in dessen einem Kanal ist ein Erwärmer des Kühlmittels angeordnet, welcher mit der Pumpe und dem Kühlmantel des Motors verbunden ist. In dem Zweikanal-Auspuffsammelrohr befindet sich eine Drosselklappe, die vorteilhaft mittels einem Thermostat gesteuert wird. In der Anfangszeit der Arbeit des Motors wird das Kühlmittel mittels einer Pumpe über einen Anwärmer gepumpt, an welchen durch das Auspuffsammelrohr heiße Verbrennungsgase zugeführt werden. Die angewärmte Flüssigkeit erwärmt den Motor innerhalb einer sehr kurzen Zeit, wodurch die Verbrennungsbedingungen im Motor stabilisiert werden.The device for reducing the ejection of the Combustion gases in engines using a coolant be cooled, consisting of cooler, pump and thermostat,  contains a two-channel exhaust manifold in its a heater is arranged for the coolant, which is connected to the pump and the cooling jacket of the motor is. Located in the two-channel exhaust manifold a throttle valve, which is advantageous by means of a Thermostat is controlled. In the early days of work The engine coolant is pumped through a heater pumped to which through the exhaust manifold hot combustion gases are supplied. The warmed liquid warms the engine inside a very short time, reducing the combustion conditions be stabilized in the engine.

Gegenstand der Erfindung wird anhand des Ausführungsbeispiels in der Zeichnung näher erläutert, in welcher ein Schema der Motoranlage dargestellt ist.The invention is based on the embodiment explained in more detail in the drawing, in which a diagram of the engine system is shown.

Der aus Gehäuse 1 und Kopf 2 bestehende Motor besitzt einen Kühlmantel 3. Die Verbrennungsgase werden vom Kopf über das Auspuffsammelrohr 4 durch die Drosselklappe 5 in das Zweikanal-Sammelrohr 6 zugeleitet. Im Kanal 7A des Sammelrohres 6 ist ein Flüssigkeitserwärmer 8 untergebracht, welcher über die Leitung 9 mit dem Kühlmantel 3 sowie der Leitung 10 und Pumpe 11 der Flüssigkeit mit dem Unterteil des Kühlmantels 3 verbunden ist. Die Pumpe 11 arbeitet zusammen mit dem Thermostat 12 und auch mit dem Kühler 13 des Motors. The motor consisting of housing 1 and head 2 has a cooling jacket 3 . The combustion gases are fed from the head via the exhaust manifold 4 through the throttle valve 5 into the two-channel manifold 6 . In the channel 7 A of the collecting pipe 6 , a liquid heater 8 is accommodated, which is connected via the line 9 to the cooling jacket 3 and the line 10 and pump 11 of the liquid to the lower part of the cooling jacket 3 . The pump 11 works together with the thermostat 12 and also with the radiator 13 of the engine.

Durch Erwärmung der Flüssigkeit im Erwärmer 8 mittels Wärme der Verbrennungsgase und ihrer Zuleitung in den Kühlmantel 3 wird die Erwärmungszeit des Motors bis auf die Temperatur seiner gewöhnlichen Arbeit sogar mehrfach verkürzt. Die Auspuffzeit der kalten Verbrennungsgase mit hoher Toxizität wird um diese Größe verkürzt.By heating the liquid in the heater 8 by means of the heat of the combustion gases and their supply to the cooling jacket 3 , the warming-up time of the engine is even shortened several times up to the temperature of its ordinary work. The exhaust time of the cold combustion gases with high toxicity is reduced by this size.

Die Zeit einer etwaigen Einschaltung der Vorrichtungen zum Nachbrennen der Verbrennungsgase ist auch kürzer. Sobald der Motor die Temperatur seiner gewöhnlichen Arbeit erreicht wird die Kühleranlage 13 vom Thermostat 12 eingeschaltet und die Lage der Drosselklappe 5 verstellt und die Verbrennungsgase werden dann vom Motor an den Austritt über den Sammelrohrkanal 6 unter Übergehung des Flüssigkeitserwärmers zugeleitet.The time when the devices for afterburning the combustion gases are switched on is also shorter. As soon as the engine reaches the temperature of its ordinary work, the cooler system 13 is switched on by the thermostat 12 and the position of the throttle valve 5 is adjusted and the combustion gases are then fed from the engine to the outlet via the manifold duct 6 , bypassing the liquid heater.
