Abstract
A method and an apparatus for the determination of the injection time in externally ignited internal combustion engines, which serve to provide the optimal injection time under given operating conditions, this injection time being derived on the basis of the rpm and the angle of the throttle valve wherein a basic injection time signal is derived from an rpm and a throttle valve angle signal and this signal is subsequently modified by means of a controlled nonlinear function generator to closely approximate an empirically ascertained optimal value for the injection time under given operating conditions, the basic injection time signal being formed in a divider circuit to provide an output signal which is fed to at least one nonlinearity function generator controllable in accordance with the throttle valve angle and the rpm.
