Abstract

Die Erfindung betrifft ein Verfahren und ein elektroni­ sches Einspritzsystem zur optimalen Anpassung der einem mit elektronischer Einspritzung ausgerüsteten Verbren­ nungsmotor zuzuführenden Kraftstoffmenge während der Beschleunigung bzw. Verzögerung. Mit der Erzeugung ei­ nes Referenzimpulses einer Impulsfolge, die der Drehzahl des Verbrennungsmotors entspricht, wird ein Zyklus gestar­ tet, in dem eine Basiskraftstoffmenge bestimmt wird, die einer lastabhängigen Korrektur unterzogen wird. Diese Ba­ siskraftstoffmenge wird beim Feststellen eines der o.g. in­ stationären Zustände mit einem in Abhängigkeit von der Temperatur des Verbrennungsmotors korrigierten Korrek­ turfaktor zum Zweck der Anreicherung bzw. Abmagerung des Luft-Kraftstoff-Gemisches multipliziert. Diese Anreiche­ rung bzw. Abmagerung wird so lange aufrecht erhalten, bis eine bestimmte Zahl der Zyklen erreicht ist. Danach wird der Korrekturfaktor in jedem Zyklus durch Multiplizieren mit einem Dekrementierfaktor dekrementiert. The invention relates to a method and an electronic cal injection system for optimal adaptation of the one combustion equipped with electronic injection Amount of fuel to be supplied to the engine during the Acceleration or deceleration. With the generation egg nes reference pulse of a pulse train, the speed of the internal combustion engine, a cycle is started tet in which a basic fuel quantity is determined, the is subjected to a load-dependent correction. This ba The amount of ice fuel is determined when one of the above in steady state with a depending on the Corrected the temperature of the internal combustion engine factor for the purpose of enrichment or emaciation of the air-fuel mixture multiplied. This empire Reduction or emaciation is maintained until a certain number of cycles has been reached. After that the correction factor in each cycle by multiplying by decremented by a decrement factor.
