Abstract

According to the invention, the two-electrode spark plug which is used to form the ignition spark is replaced by two electrode bodies which are separate from one another and project into the combustion chamber in the engine cylinder. The distance between the two electrode tips is 7...30 mm and the voltage of the ignition current [sic] which is used to form the ignition spark between these two electrode tips is 70,000...300,000 volts. The actual values of the electrode tip separation and ignition-current [sic] voltage are matched to one another and are defined as a function of the shape of the combustion chamber, the size of the cylinder bore, the fuel-air mixture ratio and the compression ratio. In order to ensure the ignition spark jumps over from the positive electrode to the negative electrode and that the ignition spark is not deflected by other electrically conductive parts in the combustion chamber, the negative electrode is subjected to continuous electrostatic charge. The advantages of the invention are: a) shorter overall duration of the combustion process as a result of combustion starting from a long ignition spark instead of a point-source ignition spark. b) Reduction in residues having hazardous material properties in the exhaust gases as a result of improved propagation of combustion in terms of speed and space. c) Achievement of constant engine powers with weaker fuel-air mixture ratios, that is to say a lower specific fuel consumption.

Description

BESCHREIBUNG DESCRIPTION

BILDUNG DES ZONDFUNKENS in den nach dem Otto-Prinzip arbeitenden Brennkraftmaschinen mit innerer Verbrennung Die Erfindung betrifft die Bildung des Zündfunkens in den nach dem Otto-Prinzip arbeitenden Brennkraftmaschinen mit innerer Verbrennung. FORMATION OF THE ZOND SPARK in those working according to the Otto principle Internal combustion engines The invention relates to the formation of the Ignition spark in the internal combustion engines working according to the Otto principle with internal Combustion.

Es ist bekannt, daß in den nach dem Otto-Prinzip arbeitenden Brennkraftmaschinen mit innerer Verbrennung das Kraftstoff-Luft-Gemisch nach der Verdichtung mit Hilfe eines Zündfunkens zum Brennen gebracht wird.It is known that in the internal combustion engines working according to the Otto principle with internal combustion using the fuel-air mixture after compression an ignition spark is made to burn.

Es ist ferner bekannt, daß zur Bildung des Zündfunkens sogenannte Zündkerzen" dienen, bei welchen der Abstand zwischen den zwei im Zündkerzenkörper befindlichen Elektroden einige Zehntel Millimeter (bis maximal 1 Millimeter) beträgt, weshalb der Zündfunken und somit der Beginn des Brennvorganges als "punktförmig" bezeichret werden können.It is also known that to form the ignition spark so-called Spark plugs "are used in which the distance between the two in the spark plug body electrodes are a few tenths of a millimeter (up to a maximum of 1 millimeter), which is why the ignition spark and thus the beginning of the burning process are considered "punctiform" can be designated.

Der Erfindung liegt die Aufgabe zugrunde, den Brennvorgang bezüglich der Gesamtbrenndauer, der Abgaszusammensetzung und des erforderlichen Kraftstoff-Luft-Mischverhältnisses zu verbessern.The invention is based on the object of the burning process the total burning time, the exhaust gas composition and the required fuel-air mixture ratio to improve.

Diese Aufgabe wird erfindungsmässig dadurch gelöst, daß die sog. "Zündkerze" durch zwei voneinander getrennten Elektrodenkörpern ersetzt wird, welche in dzn Brennraum des betreffenden Motorzylinders hineinragen. Der Abstand zwischen den zwei Elektrodenspitzen beträgt zwischen 7 mm und 30 mm und der zur Bildung des Zündfunkens zwischen diesen beiden Elektrodenspitzen dienende Zündstrom hat eine Spannung zwischen 70 000 Volt und 300 000 Volt, wobei der Elektrodenspitzenabstand und die Zündstromspannung konstruktionsmäßig aufeinander abgestimmt und in Abhängigkeit von Brennraumgestawtung, Zvlinderbohrungsgröße, Kraftstoff-Luft-Mischverhältnis und Verdichtungsgrad festgelegt werden.This object is achieved according to the invention in that the so-called "spark plug" is replaced by two separate electrode bodies, which are in dzn Project into the combustion chamber of the relevant engine cylinder. The distance between the two electrode tips is between 7 mm and 30 mm and the one to form the ignition spark The ignition current serving between these two electrode tips has a voltage between 70,000 volts and 300,000 volts, with the electrode tip spacing and the ignition voltage coordinated in terms of construction and depending on the combustion chamber design, Cylinder bore size, fuel-air mixture ratio and degree of compression are specified will.

Um ein Ablenken des Zündfunkens durch andere elektrisch leitende Teile des Brennraumes zu verhindern, steht die Minus-Elektrode unter ständiger elektrostatischen Ladung, welche das Oberspringen des Zündfunkens von der Plus-Elektrode auf die Minus-Elektrode sichert.To prevent the ignition spark from being deflected by other electrically conductive parts To prevent the combustion chamber, the minus electrode is subject to constant electrostatic Charge that causes the spark to jump from the plus electrode to the minus electrode secures.

- Fo-tsezung auf Blatt 2 - Blatt 2 der Beschreibung zur Erfindung BILDUNG DES ZONDFUNKENS in den nach dem Otto-Prinzip arbeitenden Brennkraftmaschinen mit innerer Verbrennung Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß: a) der von einem Zündfunken von mehreren Millimetern Länge eingeleitete Brennvorgang eine kürzere Gesamtbrenndauer aufweist, da die Fortpflanzung der Verbrennung vom strichförmigen Zündfunken aus zylinderförmig erfolgt, anstelle in der bisherigen Lösungsweise kugelförmig von einem punktförmigen Zündfunken ausgehend, b) die Verbrennung, durch ihre geschwindigkeits- und raummässig verbesserte Fortpflanzung, optimaler erfolgt und dadurch der Anteil in den Abgasen an Rückständen mit Schadstoffeigenschaften, welche auf unvollkommene Verbrennung im Brennraum zurückzuführen sind, erheblich gesenkt wird; c) durch Verbesserung des Brennvorganges dieselben Leistungen durch ärmere Kraftstoff-Luft-Mischverhältnisse, demzufolge mit geringerem spezifischen Kraftstoffverbrauch erzielt werden. - Continuation on sheet 2 - Sheet 2 of the description to the invention FORMATION OF THE SPARK in the internal combustion engines working according to the Otto principle with internal combustion The advantages achieved with the invention exist in particular in that: a) that initiated by an ignition spark several millimeters long Burning process has a shorter total burn time, since the propagation of the combustion from the line-shaped ignition spark takes place in a cylindrical shape, instead of the previous one In a spherical solution, starting from a point-shaped ignition spark, b) the combustion, through their speed and space improved reproduction, more optimal takes place and thereby the proportion in the exhaust gases of residues with pollutant properties, which can be traced back to incomplete combustion in the combustion chamber, considerably is lowered; c) the same performance by improving the burning process poorer fuel-air mixing ratios, therefore with lower specific Fuel consumption can be achieved.
