ABSTRACT:
A method and apparatus for determining the injected fuel quantity in internal combustion engines having self-ignition are proposed. A performance graph is prepared which includes the injected fuel quantity per stroke in accordance with the injection duration, with the rpm as a parameter. In order to avoid a fictive 0 point, the injection duration is shortened by a predetermined period of time and multiplicatively linked with an rpm signal, while linear rpm correction curves having a dependency of the rpm voltage on the injection duration can be assumed. At the output of an integrator by means of a sample and hold circuit, an injection quantity signal is produced whenever the rpm signal (Un) is supplied to the integrator for the integration process and the duration of the integration is determined on the basis of the injection duration signal (SD).
