Glühstiftkerze für Brennkraftmaschinen Sheathed- element glow plug for internal combustion machines
Die Erfindung bezieht sich auf eine GlUhstiftkerze für Brennkraftmaschinen mit Rohrheizkörper, der mit einer Heizwendel mit vom brennraumseitigen zum hintern Rohrende hin zunehmender Steigung versehen ist.The invention relates to a glow plug for internal combustion engines with tubular heating element, the one with a heating coil with an increasing gradient from the combustion chamber to the rear end of the tube is provided.

Temperatur an das vordere, brennraumseitige Glühstiftende zu legen, wo die Entflammung des Kraftstoff-Luftgemisches erfolgt. Eei bekannten GlUhstiftkerzen wird das Optimum aber nicht erreicht, weil ihre Anheizzeit verhältnismäßig lang ist. Dies ist darauf zurückzuführen, daß am vorderen Glühstiftende keine ausreichende Wärmekonzentration stattfindet, wenn die Steigung der Glühwendelwindungen am hinteren Glühwendelende nur etwa das 1,5-fache der Steigung der Glühwendelwindungcn am vorderen Glühwendelende beträgt.Set the temperature at the front end of the glow plug on the combustion chamber side, where the fuel-air mixture ignites. With known glow pencil plugs, however, the optimum is not achieved because their heating-up time is relatively long is. This is due to the fact that there is insufficient heat concentration at the front end of the glow plug. if the slope of the incandescent filament windings at the rear end of the incandescent filament is only about 1.5 times the incline of the incandescent filament windings at the front end of the filament.
Eine wesentliche Verkürzung der Anheizzeit einer Glühstiftkerze kann dagegen dadurch erreicht werden-, daß gemäß der Erfindung die Staigung der Heizwendelwindungen am hinteren Ende der Heizwendel mindestens doppelt so groß ist wie am vorderen Heizwendelende.A significant reduction in the heating-up time of a sheathed-element glow plug, on the other hand, can be achieved in accordance with the invention the pitch of the heating coil turns at the rear end of the heating coil is at least twice as large as at the front Heating coil end.
Mit einer in dieser V/eise aufgewickelten Heizwendel konnte die Aufheizzeit eines Glühst!fts auf 9CO0C von 45 see. bei bekannten Glühstiftkerzen auf 30 see. herabgesetzt werden. Dadurch wird die Startfreudigkeit von Dieselmotoren wesentlich gefördert.With a heating coil wound in this way, the heating time of an incandescent plug to 9CO 0 C could be 45 seconds. with known glow plugs on 30 see. be reduced. This significantly promotes the ease of starting diesel engines.
In der Zeichnung ist ein Schnitt durch einen Rohrheizkörper für eine Glühstiftkerze dargestellt. Dabei ist das Glührohr mit 10 bezeichnet. Es enthält als wesentlichen Bestandteil eine Heizwendel, deren vorderer mit dem geschlossenen Glührohrende verbundener Teil 11 mit geringer Steigung gewickelt ist, so daß die Heizleistung der Wendel auf das brennraumseitige Ende des Glühstifts konzentriert ist. Der Teil 11 der Glühwendel erstreckt sich über weniger als die Hälfte der Wendellänge. Der längere Teil 12 Jer Wendel ist mit einer SteigungThe drawing shows a section through a tubular heater for a glow plug. Here is the glow tube denoted by 10. It contains a heating coil as an essential component, the front of which with the closed glow tube end connected part 11 is wound with a slight pitch, so that the heating power of the coil on the combustion chamber side The end of the glow plug is concentrated. Part 11 of the incandescent filament extends over less than half the length of the filament. The longer part 12 Jer Wendel is with a slope

An ihrem hinteren Ende ist der Wendelteil 12 mit einem in das Gltlhrohr 10 hineinragenden Anschlußbolzen IJ verbunden.waved, which is more than twice as large as the slope of the helix turns in the helix part 11. At its rear end is the spiral part 12 with a protruding into the glow tube 10 Connection bolt IJ connected.
