Title (EN) METHOD FOR REGULATING IGNITION ENERGY
(FR) PROCÉDÉ PERMETTANT LA RÉGULATION D'UNE ÉNERGIE D'ALLUMAGE
(DE) VERFAHREN ZUR REGELUNG DER ZÜNDENERGIE
Abstract:
(EN) The invention relates to a method for regulating ignition energy. The method is intended to be performed with an ignition system (1) of an internal combustion engine having spark ignition. Said ignition system (1) comprises an ignition coil (3), which has a primary circuit (5) and a secondary circuit (7), and a spark plug (11) arranged in the secondary circuit (7) on a combustion chamber of the internal combustion engine. For a current operating cycle (i+1) of the internal combustion engine, a setting (EZS,i+1 = f(lZS,i+1, tZS,i+1)) is determined as a function of a determined breakdown voltage (UZ, i) of the preceding operating cycle (i) and is provided for regulating the ignition energy (EZ) in the current operating cycle.
(FR) L'invention concerne un procédé permettant la régulation de l'énergie d'allumage. Ce procédé est destiné à être mis en œuvre avec un système d'allumage (1) d'un moteur à combustion interne à allumage commandé. Ce système d'allumage (1) comporte une bobine d'allumage (3) pourvue d'un circuit primaire (5) et d'un circuit secondaire (7) ainsi qu'une bougie d'allumage (11) disposée dans le circuit secondaire (7) sur une chambre de combustion du moteur à combustion interne. Pour un cycle de travail actuel (i+1) du moteur à combustion interne, une prescription de réglage (EZS,i+1 = f(lZS,i+1, tZS,i+1)) est déterminée en fonction d'une tension de claquage (UZ, i) déterminée de chaque cycle de travail précédent (i) et fournie pour la régulation de l'énergie d'allumage (EZ) dans le cycle de travail actuel.
(DE) Verfahren zur Regelung der Zündenergie, wobei das Verfahren zur Ausführung mit einem Zündsystem (1) einer Brennkraftmaschine mit Fremdzündung vorgesehen ist, welches Zündsystem (1) eine Zündspule (3) mit einem Primärkreis (5) und einem Sekundärkreis (7) sowie eine im Sekundärkreis (7) an einem Brennraum der Brennkraftmaschine angeordnete Zündkerze (11) aufweist, wobei für ein aktuelles Arbeitsspiel (i+1) der Brennkraftmaschine eine Stellvorgabe (EZS,i+1 = f(lZS,i+1, tZS,i+1)) in Abhängigkeit einer ermittelten Durchbruchspannung (UZ, i) je des vorhergehenden Arbeitsspiels (i) ermittelt und für die Regelung der Zündenergie (EZ) im aktuellen Arbeitsspiel bereitgestellt wird.
