Abstract
A method for electronic trimming of at least one fluid injection pump, in which a control signal which is corrected for injection pump operation and, preferably, a control signal which is corrected for engine operation as well are determined by a control module of an electronic control device and are used for operation of the fluid injection pump, and in which, furthermore, a fluid injection pump is used which operates on the energy storage principle and whose feed characteristic follows an at least third-order polynomial identically or at least largely approximately and the parameters are determined in predetermined standard conditions for an at least third-order standard polynomial, are stored and are used in the determination of the required fuel injection quantity.
