Description

Im.Ottomotor wird die Zündung durch einen elektrischen Funken eingeleitet. Der hochgespannte Zündstrom wird zu diesem Zwecke isoliert in den Verbrennungsraum des Motors eingeführt; zwischen dem Kabelende und der Zündkerze verwendet man nicht mehr eine gewöhnliche Metallklemme als Verbindung, sondern es hat sich allmählich hier eine Einrichtung durchgesetzt, die im wesentlichen aus einer Verschlußkappe aus hitzebeständigem Kunststoff besteht, in die das Zündstromkabel von der Seite eingeführt wird, während die Kappe selbst dann von oben auf die Zündkerze gedrückt wird.In the gasoline engine, ignition is initiated by an electric spark. For this purpose, the high-voltage ignition current is isolated in the combustion chamber of the engine introduced; between the end of the cable and the spark plug is not used more of an ordinary metal clamp as a connection, rather it has gradually become Here a device is enforced, which essentially consists of a closure cap is made of heat-resistant plastic, into which the ignition current cable is inserted from the side is inserted while the cap itself is then pressed onto the spark plug from above will.

Diese Einrichtung hat verschiedene Vorteile, die hier nicht erwähnt werden brauchen. Sie hat aber auch einen Nachteil. Es ist nämlich außerordentlich schwer, bei Versagen der Zündung in einem einzelnen Zylinder festzustellen, um welchen Zylinder es sich handelt, da man eben nicht mehr an die Mittelelektrode der Zündkerze bzw. deren obere Verlängerung heran kann, ohne gleichzeitig mit einer Entfernung der sonst alles verdeckenden Isolierkappe auch die Zündstromzufuhr zu unterbrechen.This facility has several advantages not mentioned here will need. But it also has a disadvantage. Because it is extraordinary difficult to determine which one in the event of an ignition failure in a single cylinder It is a cylinder because you no longer have to touch the center electrode of the spark plug or their upper extension can be approached without simultaneously with a removal the otherwise all-covering insulating cap to also interrupt the ignition current supply.

Man kann beim Laufen des Motors nur unter sehr erschwerten Umständen bzw. gar nicht einen Kerzenprüfer oder sonst übliche Methoden der Feststellung (z. B. Kurzschließen mittels Schraubenzieher) zur Anwendung bringen.One can only run the engine under very difficult circumstances or not at all a candle tester or other common methods of determination (e.g. B. Short-circuit using a screwdriver) apply.

Die vorliegende Erfindung beseitigt nun diesen Übelstand, indem in jeden solchen Kabelschuh aus Kunststoff ein an sich bekannter Kerzenprüfer eingebaut ist, so daß man spfort feststellen kann, welche Kerze aussetzt bzw. unregelmäßig arbeitet.The present invention now eliminates this drawback by in Each such plastic cable lug has a known candle tester built into it so that you can immediately determine which candle is missing or irregular is working.

Die Erfindung ist in der Zeichnung beispielsweise veranschaulicht. Es stellen dar: i die Zündkerze, 2 den Körper des Kabelschuhs aus Kunststoff, 3 die Spiralfeder zur Zündkerzenverbindung, .4 den Widerstand zur Zündkerze, 5 den Anschluß für Zündkabel, 6 das Glimmrohr, 7 den Druckknopf, 8 die Spiralfeder, 9 den Sehschlitz für das Glimmrohr.The invention is illustrated in the drawing, for example. They represent: i the spark plug, 2 the body of the plastic cable lug, 3 the spiral spring for the spark plug connection, .4 the resistance to the spark plug, 5 den Connection for ignition cable, 6 the glow tube, 7 the push button, 8 the spiral spring, 9 the viewing slit for the glow tube.

Durch Herandrücken des Knopfes (in Pfeilrichtung) wird das Glimmrohr an die Zündkerzenverbindung herangebracht. Der Knopf aus Metall ergibt durch den Körper des Prüfers die Erdung, jedoch nicht etwa für den Zündstrom, der in Gestalt eines Funkens an den Elektroden der Zündkerze überspringt, sondern für den unschädlichen Glimmfunken.By pressing the button (in the direction of the arrow) the glow tube brought to the spark plug connection. The metal button results from the Body of the examiner provides the grounding, but not for the ignition current, which is in the form a spark on the electrodes of the spark plug skips, but for the harmless Glow sparks.
