Description

Vorrichtung zur Prüfung und Messung des Zündstromflusses durch Zündkerzen und Zündapparate bei Brennkraftmaschinen Die vorliegende Erfindung betrifft eine Vorrichtung zur Prüfung und Messung des Zündstromflusses durch Zündkerzen und Zündapparate bei Brennkraftmaschinen, bei denen das Anzeigegerät in einem gewhlossenzn, aus zwei besonderen Leitungen bestehenden Stromkreise liegt, der mittels j e eines Meßwandlers an den Zündstromkreis der Zündkerzen angeschlossen ist. Erfindungsgemäß soll in die Meßstromkreise je eirie Glühbirne oder je ein elektrisches Anzeigegerät, wie z. B. Voltmesser oder Amperemesser, leingebaut werden. Es kann aber auch nur eine Anzeigeeinrichtung vorgesehen sein, welche wahlweise in die verschiedenen Meßwandlerkrehe eingeschaltet werden kann.Device for testing and measuring the Zündstromflusses by spark plugs and ignition devices for internal combustion engines The present invention relates to a device for testing and measuring the Zündstromflusses by spark plugs and ignition devices for internal combustion engines, in which the display unit b in a gewhlossenzn, particular of two lines is estehenden circuits, the is connected to the ignition circuit of the spark plugs by means of a transducer each. According to the invention, in the measuring circuits each egg bulb or an electrical display device, such as. B. voltmeter or ammeter, can be built in. However, only one display device can be provided, which can optionally be switched into the various measuring transducers.

Es sei darauf hingewiesen, daß zwar Anzeiger für Zündeinrichtungen mit Glühbirnen bekannt sind, die aber unmittelbar in den Zündstromkreis parallel zu einem Widerstand geschaltet werden, nicht aber in einem besonderen an den Zündstromkreis durch einen Meßwandler angekoppelten 1Vleßstromkreis liegen, wodurch die Glühbirnen von dem Zündstrom selbst nicht durchflossen werden.It should be noted that while indicators for ignition devices with lightbulbs are known, but which are directly parallel to the ignition circuit be switched to a resistor, but not in a special to the ignition circuit through a transducer coupled 1Vleßstromkreis lie, whereby the lightbulbs are not flowed through by the ignition current itself.

Erfindungsgemäß kann auch durch besondere Abstimmung der Meßwandler der Kompressionsdruck in den-einzelnen Zylindern geprüft werden, da der Zündstrom vom Verdichtungszustand der Ladung innerhalb der Funkenstrecke abhängig ist. Je stärker das-Gas verdichtet ist, desto höher ist der Widerstand, der dem Zündstrom entgegensteht. Da sich aber mit steigendem Widerstand die Spannung des Zündstromes erhöht, steigt auch der Induktionsstrom der Meßwandler, der bei einer :gewissen Höhe die Anzeigegeräte in Tätigkeit setzt und dessen Anwachsen bzw. Abfallen durch ein Anzeigegerät erkenntlich gemacht werden kann, wodurch die Höhe des Verdichtungsdruckes im Zylinder feststellbar wird.According to the invention, the transducers can also be tuned in a special way the compression pressure in the individual cylinders must be checked as the ignition current depends on the compression state of the charge within the spark gap. Ever The more the gas is compressed, the higher the resistance to the ignition current opposes. But since the voltage of the ignition current increases with increasing resistance increases, so does the induction current of the transducers, which at a certain Height sets the display devices in action and its increase or decrease a display device can be made recognizable, whereby the level of the compression pressure becomes detectable in the cylinder.

In der Zeichnung ist schematisch der Meßstromkreis dargestellt, wobei die Strecken A-B ein Teil der Zündstromkreise, E die Leitungen der Meßstromkreise und F die Prüfvorrichtung sind. Weiterhin bedeuten die Bezeichnungen C die in. den Zündstromkreisen, eingeschalteten Primärspulen und D die Selrundärspulen der Meßwandler.In the drawing, the measuring circuit is shown schematically, wherein the lines A-B part of the ignition circuits, E the lines of the measuring circuits and F is the test device. Furthermore, the designations C mean in. The Ignition circuits, activated primary coils and D the secondary coils of the transducers.

Die abgestimmten Meßwandlerkreise bieten den Vorteil, däß man den Verdichtungsdruck während der Fahrt prüfen kann. Es können auf diese Weise undichte Zylinder festgestellt werden.The matched transducer circuits offer the advantage that you can use the Can check compression pressure while driving. It can leak that way Cylinder can be determined.
