Abstract

The device for partial carbon monoxide (CO) detoxification is a carburettor accessory. It operates by means of controlled air ingress (additional air) and is used in car engines (carburettor engines). The additional air is drawn in via a filter by means of a solenoid valve after, preheated by the exhaust manifold, it has reached the required running temperature of the engine. In the case of water-cooled carburettor engines, the solenoid valve is controlled by a thermal switch, and by a timer in the case of air-cooled engines. The carburettor accessory serves to lower the carbon monoxide (CO) from the statutory upper limit of, at present, 4.5% by volume on idling to 0.1-0.3% by volume. In addition, it effects the lowering of the unburnt hydrocarbons (HC) in the exhaust gas of the carburettor engines from the general values in the range of 300-400 ppm (parts per million) to about 150 ppm and improved combustion throughout the speed range. The motor speed here remains unchanged. There is no decrease in performance. The fuel consumption remains unaffected.

Description

Beschreibungdescription

Titel: Te ilentgiftungsanlage durch gesteuerte Falschluft für Kfz.- Motoren.Title: Partial detoxification system through controlled false air for motor vehicle engines.

Gattung des Anmeldungsgegenstandes: Die Erfindung betrifft ein Vergaser-Zusatzgerät zur besseren Verbrennung und zur Herabsetzung des Kohlenmonoxyds (CO) und der unverbrannten Kohlenwasserstoffe (HC).Type of the subject of the application: The invention relates to an additional carburetor device for better combustion and to reduce carbon monoxide (CO) and unburned ones Hydrocarbons (HC).

Angabe zur Gattung: Das Vergaser-Zusatzgerät soll das in den Abgasen enthaltene Kohlenmonoxyd (CO) und die unverbrannten Kohlenwasserstoffe (etc) herabsetzen und gleichzeitig die Verbrennung verbessern.Information on the type: The additional carburetor device should do this in the exhaust gases Reduce the carbon monoxide (CO) contained and the unburned hydrocarbons (etc) and at the same time improve combustion.

Stand der Technik: Es ist bekannt, daß es Anlagen zur teilweisen Entgiftung der Abgase gibt. Das wird dadurch erreicht, daß die Abgase in dèn Ansaugkrümmer und Frischluft in den Abgaskrümmer gedrückt werden.State of the art: It is known that there are partial detoxification plants the exhaust fumes. This is achieved by keeping the exhaust gases in the intake manifold and fresh air is forced into the exhaust manifold.

Kritik des Standes der Technik: Dabei ist allerdings ein erheblicher technischer Aufwand erforderlich. Außerdem ist ein nicht unwesentlicher Leistungsverlust damit verbunden.Criticism of the state of the art: This is, however, a considerable one technical effort required. In addition, there is a not insignificant loss of performance associated with it.

Aufgabe: Der Erfindung liegt die Aufgabe zugrunde, Kohlenmonoxyd (CO) und unverbrannte Kohlenwasserstoffe (etc) des Motorabgases zu reduzieren.Task: The invention is based on the task of producing carbon monoxide (CO) and reduce unburned hydrocarbons (etc) in engine exhaust.

Lösung: Diese Aufgabe wird erfindungsmäßig dadurch gelöst, daß gesteuerte Palschluft (Zusatzluft) durch einen Luftanschluß am .tnsaugkrümmer über einen Filter angesaugt wird.Solution: According to the invention, this object is achieved in that controlled Palschluft (additional air) through an air connection on the intake manifold via a filter is sucked in.

Dieser Vorgang wird durch ein Magnetventil -aber erst nach Erreichen der erforderlichen Betriebstemperatur des Motors -Das Magnetventil wird bei wassergekühlten Motoren durch einen Thermoschalter gesteuert. This process is activated by a solenoid valve - but only after it has been reached the required operating temperature of the engine -The solenoid valve is water-cooled Motors controlled by a thermal switch.

Bei luftgekühlten Motoren erfolgt die Steuerung durch ein Zeitglied. In the case of air-cooled motors, the control is carried out by a timer.

Erzielte Vorteile: Der mit der Erfindung erzielte Vorteil besteht insbesondere darin, daß nach der Leerlaufeinstellung das Kohlenmonoxyd (CO) und die unverbrannten Kohlenwasserstoffe (HC) des Motorabgases erheblich reduziert werden. Mittels einer Regulierschraube am Magnetventil lassen sich die Abgaswerte des Kohlenmonoxyds (CO) problemlos von dem gesetzlich noch zulässigen Höchstwert von 4,5 Vol.% auf 0,1 - 0,3 Vor.% absenken. Die unverbrannten Kohlenwasserstoffe (HC) werden dabei gleichzeitig von den häufig anzutreffenden Werten im Bereich von 300 - 400 PPM (parts per million) auf ca. 150 PPM abgesenkt. Die Motorleistung bleibt unbeeinträchtigt. Die Leerlaufdrehzahl bleibt unverändert.Achieved advantages: The advantage achieved with the invention exists in particular that after the idle setting, the carbon monoxide (CO) and the unburned hydrocarbons (HC) of the engine exhaust gas are significantly reduced. The exhaust gas values of the carbon monoxide can be adjusted using a regulating screw on the solenoid valve (CO) up from the legally permissible maximum value of 4.5% by volume without any problems Reduce 0.1 - 0.3%. The unburned hydrocarbons (HC) are thereby at the same time from the frequently encountered values in the range of 300 - 400 PPM (parts per million) reduced to approx. 150 PPM. The engine performance remains unaffected. The idle speed remains unchanged.

Der Kraftstoffverbrauch erhöht sich nicht. The fuel consumption does not increase.
