Abstract

In spark plugs, the metal housing (63) is earthed (5) to the vehicle via the cylinder head (71) of the engine (7). This is inadequate with a powerful ignition spark. To improve ignition, each spark plug (31 to 34) is fitted with an additional earthing cable (41 to 44) which is attached to the housing (63) of the appropriate spark plug. These additional earthing cables (41 to 44) are connected to a common earthing cable (4) which is in turn connected to the negative terminal (12) of the battery (1).

Description

Masseanschluß für die Zündkerzen eines Mehrzylinder- Verbrennungsmotors für ein Fahrzeug Earth connection for the spark plugs of a multi-cylinder internal combustion engine for a vehicle
Technisches Gebiet:Technical field:
Die Erfindung betrifft einen Masseanschluß für die Zündkerzen eines Mehrzylinder-Verbrennungsmotors für ein Fahrzeug, wobei das metallische Kerzengehäuse jeder Zünd¬ kerze eine Masseelektrode aufweist und in einen Zylinder¬ kopf des Motors geschraubt ist und wobei der Motor mit einer Fahrzeugmasse und die Fahrzeugmasse mit einem Pol der Batterie des Fahrzeugs elektrisch verbunden ist.The invention relates to a ground connection for the spark plugs of a multi-cylinder internal combustion engine for a vehicle, the metallic plug housing of each spark plug having a ground electrode and being screwed into a cylinder head of the engine, and the engine having a vehicle ground and the vehicle ground having a pole the battery of the vehicle is electrically connected.
Stand der Technik:State of the art:
Zündkerzen sind Bestandteile einer Zündanlage für einen Verbrennungsmotor eines Fahrzeugs. Jede Zündkerze be- steht aus einer Metallmittelelektrode, die in einen Keramikisolator eingebettet ist. Der untere Teil des Isolators wird von einem metallischen Kerzengehäuse aufgenommen, das ein Anschlußgewinde zum Einschrauben der Kerze in einen Zylinderkopf des Motors hat. Am Kerzenfuß ist eine zweite Elektrode, die Masseelektrode, angeschweißt. Die Masseelektrode ist über den Zylinder¬ kopf des Motors mit Fahrzeugmasse verbunden. Die Masseelektrode hat einen festgelegten Luftspalt zur Mittelelektrode, den Elektrodenabstand. Hochge¬ spannter, vom Verteiler kommender Zündstrom fließt durch die Mittelelektrode und überbrückt den Elektroden- abstand als überschlagender Zündfunken.Spark plugs are components of an ignition system for an internal combustion engine of a vehicle. Each spark plug consists of a metal center electrode which is embedded in a ceramic insulator. The lower part of the insulator is held by a metallic plug housing, which has a connection thread for screwing the candle into a cylinder head of the engine. A second electrode, the ground electrode, is welded onto the candle base. The ground electrode is connected to the vehicle ground via the cylinder head of the engine. The ground electrode has a fixed air gap to the center electrode, the electrode gap. High voltage ignition current coming from the distributor flows through the central electrode and bridges the electrode gap as a spark.
Für eine angemessene Motorleistung muß der Funken kräftig genug sein, um das Kraftstoffgemisch zu zünden. Dies erfordert einen relativ großen Elektroden- abstand. Je größer jedoch der Elektrodenabstand ist, um so größer muß auch die zur Erzeugung des Zünd¬ funkens erforderliche Spannung sein.For proper engine performance, the spark must be strong enough to ignite the fuel mixture. This requires a relatively large electrode gap. However, the greater the distance between the electrodes, the greater the voltage required to generate the ignition spark.
Darstellung der Erfindung:Presentation of the invention:
Der Erfindung liegt die Aufgabe zugrunde, einen Masse¬ anschluß zu schaffen, mit dessen Hilfe die Zündung verbessert wird. Dabei geht die Erfindung von der Erkenntnis aus, daß es nicht nur auf die Vergrößerung der Spannung ankommt. Vielmehr ist die Erfindung dadurch gekennzeichnet, daß zur Verbesserung der Zündung für jede Zündkerze ein zusätzliches Masse¬ kabel vorgesehen ist, das jeweils mit dem Kerzenge¬ häuse der zugeordneten Zündkerze verbunden ist, und daß die zusätzlichen Massekabel an ein gemeinsames Massekabel angeschlossen sind, das mit dem Minuspol der Batterie verbunden ist. The invention has for its object to provide a ground connection, with the aid of which the ignition is improved. The invention is based on the knowledge that it is not only a question of increasing the voltage. Rather, the invention is characterized in that in order to improve the ignition, an additional ground cable is provided for each spark plug, which is connected to the plug housing of the associated spark plug, and in that the additional ground cables are connected to a common ground cable connected with the negative pole of the battery is connected.
Folgende Vorteile werden mit dem Masseanschluß nach der Erfindung erzielt: Es wird ein deutlich kräftigerer Zündfunke erzeugt. Der Motor springt besser an als ein Motor ohne zusätzliches Massekabel. Sein Kalt- lauf ist besser; der Motor bockt nicht. Der Motor erreicht schneller seine Betriebstemperatur, wird aber nicht zu heiß. Der Warmlauf des Motors ist ruhig und kräftig. Der Spurt des Fahrzeugs ist besser, unabhängig davon ob der Motor noch kalt oder schon warm ist. Die Leistung des Motors am Berg ist sehr gut. Der Kraftstoffverbrauch ist geringer. - Bei einem bestimmten Fahrzeug sank bei Kurzstreckenfahrt der Verbrauch von 14 1/100 km auf 11 1/100 km; bei Autobahnfahrt mit einer Geschwindigkeit von 130 km/h sank der Verbrauch von 9 1/km auf 7,5 1/km -. Der kräftigere Zündfunke führt zu weniger Zündaus¬ setzern. Die Verbrennung des Kraftstoffs erfolgt sauberer und umweitschonender. Auch die Zündkerzen bleiben sauberer. Schließlich ist auch der Brenn¬ raum - Kolben und Ventile - sauberer. Die optimale Einstellung des Motors mit Hilfe des zusätzlichen Massekabels führt zu Ergebnissen, die auch bei der Abgas-Sonderuntersuchung beachtlich sind.The following advantages are achieved with the ground connection according to the invention: A significantly more powerful spark is generated. The engine starts better than an engine without an additional earth cable. His cold run is better; the engine doesn't buck. The engine reaches its operating temperature faster, but does not become too hot. Warming up the engine is calm and powerful. The sprint of the vehicle is better, regardless of whether the engine is still cold or already warm. The performance of the engine on the mountain is very good. The fuel consumption is lower. - In the case of a certain vehicle, consumption on short journeys dropped from 14 1/100 km to 11 1/100 km; when driving on the motorway at a speed of 130 km / h, consumption fell from 9 1 / km to 7.5 1 / km -. The stronger ignition spark leads to fewer misfires. The combustion of the fuel is cleaner and more environmentally friendly. The spark plugs also stay cleaner. Finally, the combustion chamber - pistons and valves - is cleaner. The optimal setting of the engine with the help of the additional earth cable leads to results that are also noteworthy during the special exhaust test.

Ober den Zündverteiler wird mit Hilfe von Leitungen 21 bis 24 jeweils einer von - im Ausführungsbeispiel - vier Zündkerzen 31 bis 34 der Zündstrom zugeführt. Die ausgezogene Leitung 21 versorgt die Zündkerze 31 mit dem Zündstrom. Die Leitungen 22 bis 24, die zu den Zündkerzen 32 bis 34 führen, sind stromfrei. Sie führen zyklisch bei der Drehung des Zündverteilers den Zündstrom.The electrical circuit of a motor vehicle is fed from a battery 1. The positive pole 12 of this battery 1 is connected to an ignition distributor via an ignition lock and an ignition coil (not shown). One of - in the exemplary embodiment - four spark plugs 31 to 34 of the ignition current is supplied via the ignition distributor with the aid of lines 21 to 24. The extended line 21 supplies the spark plug 31 with the ignition current. The lines 22 to 24, which lead to the spark plugs 32 to 34, are de-energized. They carry the ignition current cyclically when the distributor is turned.
Der Minuspol 13 der Batterie 1 ist mit Fahrzeug¬ masse 5, in der Regel mit der Fahrzeugkarosserie, verbunden. An die Fahrzeugmasse 5 sind auch alle übrigen elektrischen Geräte des Kraftfahrzeugs angeschlossen. Bei dem Masseanschluß nach der Erfindung geht zusätzlich ein Massekabel 4 von dem Minuspol 13 der Batterie 1 aus. An dieses zusätzliche Masse¬ kabel 4 sind Nebenkabel 41 bis 44 angeschlossen, von denen jedes mit einer der Zündkerzen 31 bis 34 verbunden ist.The negative pole 13 of the battery 1 is connected to the vehicle earth 5, usually to the vehicle body.
