Description

Die bekannten, zur Schonung der Umwelt vor den schädlichen Abgasen notwendigen Katalysatoren von Verbrennungs-Kraftmaschinen sind in ihrer Anwendung beschränkt auf Anlagen, Fahrzeuge usw., bei denen die hohen Aussentemperaturen des Katalysatorgehäuses beim Betrieb keine Rolle spielen. In wärmeempfindlicher Umgebung, wo die starke Aufheizung des Katalysatormantels zu Brand- oder Explosionsgefahr führen kann, musste bisher auf einen Katalysator verzichtet werden. Die Anwendung von Katalysatoren auf Motorbooten, in Flugzeugen usw., wo sie an sich ebenso erwünscht wäre, war daher nicht möglich. The known catalysts of internal combustion engines, which are necessary to protect the environment from the harmful exhaust gases, are limited in their application to systems, vehicles, etc., in which the high outside temperatures of the catalyst housing play no role during operation. In a heat-sensitive environment, where the excessive heating of the catalyst jacket can lead to fire or explosion, it has so far been necessary to dispense with a catalyst. The use of catalytic converters on motor boats, in aircraft, etc., where it would also be desirable per se, was therefore not possible.

Ziel der Erfindung ist es, diesen Übelstand zu beseitigen und die Oberflächentemperatur des Katalysators so niedrig zu halten, dass sie keine Gefahr darstellt, ohne dessen Wärmehaushalt zu beeinträchtigen. The aim of the invention is to eliminate this problem and to keep the surface temperature of the catalyst so low that it does not pose a danger without affecting its heat balance.

Zu diesem Zweck ist der Katalysator gemäss der Erfindung mit einer Oberflächenkühlung versehen. Diese besteht vorzugsweise aus einer inneren, den Katalysator ganz oder teilweise umgebenden, Isolierschicht und einem diese umgebenden Kühlmantel, in welchem ein flüssiges oder gasförmiges Kühlmedium geführt ist. Die Isolierschicht kann ein Luftspalt zwischen dem Monolithengehäuse und dem Kühlmantel oder auch nur eine verstärkte Ausführung des Monolithengehäuses sein. Ebenso kommt eine Feststoffschicht als Isolierschicht in Frage. For this purpose, the catalyst according to the invention is provided with surface cooling. This preferably consists of an inner insulating layer that completely or partially surrounds the catalyst and a cooling jacket surrounding it, in which a liquid or gaseous cooling medium is guided. The insulating layer can be an air gap between the monolith housing and the cooling jacket or just a reinforced version of the monolith housing. A solid layer can also be used as an insulating layer.

Die Erfindung betrifft auch eine flüssigkeits- oder gasgekühlte Verbrennungs-Kraftmaschine mit einer kennfeld- und lambdageregelten Zünd- und Gemischaufbereitungsanlage und einem kennfeld- und lambdageregelten 3-Wege-Katalysator, die sich dadurch auszeichnet, dass sie mit einem Katalysator gemäss der Erfindung ausgerüstet ist. Der Kühlkreislauf des Katalysators kann dann vorteilhaft in den Kühlkreislauf der Maschine integriert sein. The invention also relates to a liquid or gas-cooled internal combustion engine with a map and lambda controlled ignition and mixture processing system and a map and lambda controlled 3-way catalytic converter, which is characterized in that it is equipped with a catalytic converter according to the invention. The cooling circuit of the catalyst can then advantageously be integrated into the cooling circuit of the machine.

Die Zeichnung zeigt zwei Ausführungsbeispiele des erfindungsgemässen Katalysators in Fig. 1 und 2 schematisch im Längsschnitt. The drawing shows two exemplary embodiments of the catalyst according to the invention in FIGS. 1 and 2 schematically in longitudinal section.

Der Katalysator nach Fig. 1 enthält zwei übliche Reaktions-Monolithen (1), die in einem Gehäuse (3) untergebracht sind, das zugleich die Ein- und Ausströmkonen (2) bildet. Die Wand des Gehäuses (3) ist derart verstärkt, dass sie einen Isoliermantel bildet, der zwei Funktionen hat: 1 contains two conventional reaction monoliths (1), which are housed in a housing (3) which also forms the inflow and outflow cones (2). The wall of the housing (3) is reinforced in such a way that it forms an insulating jacket that has two functions:

1. Nach dem Start erlaubt er eine rasche Aufwärmung der Monolithen auf ihre Mindestbetriebstemperatur. 2. Im Betrieb hilft er den Wärmehaushalt der Monolithen zu regulieren. Dies dadurch, dass der Wärmefluss durch den Isoliermantel in den Kühlmantel durch konstruktive Massnahmen wie Verändern der Dicke, des Wärmeleitkoeffizienten und anderes mehr variiert werden kann.  1. After starting, it allows the monoliths to warm up quickly to their minimum operating temperature.  2. In operation, it helps regulate the heat balance of the monoliths. This is due to the fact that the heat flow through the insulating jacket into the cooling jacket can be varied by constructive measures such as changing the thickness, the coefficient of thermal conductivity and others.

Der Isoliermantel (3) ist von einem Kühlmantel umgeben, in welchem ein Kühlmedium zirkuliert, das durch die Anschlüsse (5) zu- und abgeführt wird. The insulating jacket (3) is surrounded by a cooling jacket in which a cooling medium circulates, which is fed in and out through the connections (5).

Der Kühlmantel hat die Aufgabe, die umgebungsrelevante Oberfläche des Katalysators auf einer definierten, niedrigen Temperatur zu halten. Dies wird dadurch erreicht, dass der Mantel an den maschineneigenen oder einen unabhängigen Kühlkreislauf angeschlossen wird. Der Kühlmantel muss so ausgelegt sein, dass er die Restwärme der Monolithen bei stillstehendem Kreislauf aufnehmen kann, ohne dass die Oberflächentemperatur unzulässig hoch ansteigt. The cooling jacket has the task of keeping the environment-relevant surface of the catalytic converter at a defined, low temperature. This is achieved by connecting the jacket to the machine's own or an independent cooling circuit. The cooling jacket must be designed in such a way that it can absorb the residual heat of the monoliths when the circuit is at a standstill without the surface temperature rising excessively.

Das Gehäuse (10) des Katalysators nach der Fig. 2 enthält wiederum die beiden Monolithen (11) und (12) mit der Mischstrecke (13) und bildet die Ein- und Ausströmstutzen (14) und (15) sowie die Konen (16) und (17). An den Endflanschen (18) ist ein Kühlmantel (19) aus den Wänden (20) und (21) angebracht, der das Gehäuse (10) in einem Abstand umgibt. Dieser Abstand bildet einen Luftspalt (22) als Isolierschicht, welche die gleichen Funktionen hat wie der Mantel (3) in Fig. 1. Das zirkulierende Kühlmedium wird durch die Stutzen (23) und (24), vorzugsweise in Gegenstrom, zu- und abgeführt. Eine gewellte Zone (25) dient zur Aufnahme von Wärmedehnungen; ferner ist eine kleine Bohrung (26) zur Be- und Entlüftung vorgesehen. The housing (10) of the catalytic converter according to FIG. 2 in turn contains the two monoliths (11) and (12) with the mixing section (13) and forms the inlet and outlet ports (14) and (15) and the cones (16) and (17). A cooling jacket (19) from the walls (20) and (21) is attached to the end flanges (18) and surrounds the housing (10) at a distance. This distance forms an air gap (22) as an insulating layer, which has the same functions as the jacket (3) in Fig. 1. The circulating cooling medium is supplied and discharged through the nozzle (23) and (24), preferably in counterflow . A corrugated zone (25) serves to absorb thermal expansion; there is also a small bore (26) for ventilation.

Mit (27) ist eine Lambda-Sonde zur Messung des Abgasgemisches bezeichnet. (27) denotes a lambda probe for measuring the exhaust gas mixture.

Dank der beschriebenen Ausführung behält der Katalysator im Betrieb eine sehr niedrige Oberflächen-Temperatur, ohne dass der Wärmehaushalt negativ beeinflusst ist. Damit wird eine Verwendnng in wärmeempfindlicher Umgebung, namentlich in Booten, Fahrzeugen und Flugzeugen ermöglicht, unter Nutzung der Vorteile des geregelten 3-Wege-Katalysators. Thanks to the design described, the catalytic converter maintains a very low surface temperature during operation without the heat balance being adversely affected. This enables use in a heat-sensitive environment, particularly in boats, vehicles and airplanes, taking advantage of the regulated 3-way catalytic converter.

Der beschriebene Katalysator ist zur Verwendung mit jeder flüssigkeits- oder gasgekühlten Verbrennungs-Kraftmaschine geeignet, die mit einer kennfeld- und lambdageregelten Zünd- und Gemischaufbereitungsanlage ausgerüstet ist. Die Kühlvorrichtung des Katalysators ist dann vorteilhaft in den Kühlkreislauf der Maschine integriert. Die Kraftmaschine kann dabei ein Benzin- oder Dieselmotor, eine Gasturbine usw. sein, ebenso ist die Erfindung auch für ungeregelte Ein-, Zwei-, oder Dreiwege-Katalysatoren geeignet. The catalytic converter described is suitable for use with any liquid or gas-cooled internal combustion engine which is equipped with a map and lambda-controlled ignition and mixture processing system. The cooling device of the catalyst is then advantageously integrated in the cooling circuit of the machine. The engine can be a gasoline or diesel engine, a gas turbine, etc., and the invention is also suitable for unregulated one-, two-, or three-way catalytic converters.

Die kennfeld- und lambdageregelte Zünd- und Gemischaufbereitungsanlage ermöglicht jedoch zusammen mit dem 3-Wege-Katalysator eine unter allen Bedingungen präzise und stabile Einhaltung von sehr niedrigen Schadstoffwerten. Ebenfalls kann die Exemplarstreuung niedrig gehalten werden. Die Anpassung der Motorparameter Leistung und Drehmoment an die Erfordernisse der Praxis kann, unter Einhaltung der vorgegebenen Schadstoffwerte, durch Kennfeldprogrammierung in einem weiten Bereich erfolgen. Es sind keine vom Benutzer verstellbaren Organe vorhanden, die die Schadstoffwerte beeinflussen. The map and lambda-controlled ignition and mixture preparation system, however, together with the 3-way catalytic converter, enables precise and stable compliance with very low pollutant values under all conditions. The spread of specimens can also be kept low. The engine parameters power and torque can be adapted to the requirements of practice, in compliance with the specified pollutant values, by map programming in a wide range. There are no user-adjustable organs that influence the pollutant values.

Durch das allseits gekühlte Abgassystem sind alle Oberflächen auf einer niedrigen Temperatur gehalten, was die Verwendung des Motors insbesondere in Booten, aber auch in anderen wärmeempfindlichen Umgebungen ermöglicht. Thanks to the all-round cooled exhaust system, all surfaces are kept at a low temperature, which enables the use of the engine, especially in boats, but also in other heat-sensitive environments.
