Description

Dleßvorrichtung für die im Zylinder einer Brennkraftmaschine herrschende Temperatur. Die Erfindung bezieht sich auf eine Vorrichtung zur Messung der in dem Zylinder einer Brennkraftmaschine herrschenden Temperatur des Betriebsmittels, die aus einem thermoelektrischen Element, das mit seinem die Verbindungsstelle der beiden verschiedenen Metalle aufweisenden Ende in den Zylinder eingebaut ist, und einem mit den freien Enden des Elements verbundenen Zeigerinstrument besteht. Die bekannten Vorrichtungen dieser Art haben den -Nachteil, daß sie sehr kompliziert sind, da sie mit einer besonderen Armatur versehen werden müssen, die ihren Einbau in den Motorzylinder ermöglicht, und daß zu diesem Zwecke an deren Zylinder besondere Bohrungen bzw. Verschraubungen angebracht werden müssen.Dleßvorrichtung for the prevailing in the cylinder of an internal combustion engine Temperature. The invention relates to an apparatus for measuring the in the Cylinder of an internal combustion engine prevailing temperature of the operating medium, the from a thermoelectric element, which with its the connection point of the two different metals having end is built into the cylinder, and one with the free ends of the element connected pointer instrument. The known Devices of this type have the disadvantage that they are very complicated because they must be provided with a special fitting that allows their installation in the Motor cylinder allows, and that for this purpose special bores on the cylinder or screw connections must be attached.

Dieser Nachteil wird durch die vorliegende Erfindung vermieden, und zwar dadurch, daß gemäß dieser das den einen Teil der Meßvorrichtung bildende thermoelektrische Element in eine der Zündkerze üblichen Art eingebaut ist, so daß es zusammen mit dieser ohne weiteres mit einem 1Iotorzvlinder in Verbindung gebracht werden kann, dessen Innentemperatur gemessen werden soll.This disadvantage is avoided by the present invention, and in that, according to this, the thermoelectric forming part of the measuring device Element is built into one of the spark plug types so that it works together with this can easily be associated with a 1Iotorzvlinder, whose internal temperature is to be measured.

In der Zeichnung ist die Vorrichtung nach der Erfindung beispielsweise in einer Ausführungsform und mehr schematisch darges teilt.In the drawing, the device according to the invention is for example in one embodiment and more schematically Darges shares.

A ist die in bekannter Weise ausgebildete, mit der Zündelektrode .1 versehene Zündkerze. In deren aus isolierendem Stoff be= stehendem Körper -sind die beiden aus verschiedenen Metallen, z. B. Nickel und Eisen, bestehenden Drähte D und E eingebaut, die bei F miteinander verlötet sind. Die beiden freien Enden des thermoelektrischen Elements D, E, F sind durch Leitungen mit dem Zeigerinstrument (Galvanometer o. dgl.) verbunden. Die Zündkerze A bzw. deren Körper ruht in der Büchse B mit dem Gewinde C, das das Einschrauben der Zündkerze A und somit auch des Elements D, E, F in die in dem Zylinder vorgesehene Zündkerzenbohrung ohne weiteres ermöglicht.A is the spark plug designed in a known manner and provided with the ignition electrode .1. In their body, which is made of insulating material, the two are made of different metals, e.g. B. nickel and iron, existing wires D and E installed, which are soldered together at F. The two free ends of the thermoelectric element D, E , F are connected to the pointer instrument (galvanometer or the like) by lines. The spark plug A or its body rests in the bush B with the thread C, which allows the spark plug A and thus also the element D, E, F to be screwed into the spark plug bore provided in the cylinder without further ado.
