Simplification of the control interface between control ASIC and microcontroller

摘要

The invention relates to a method for controlling fuel injection devices of an internal combustion engine, wherein an ON signal is used to control the injections, wherein an ON signal is present per bank, wherein a charging phase or a discharge phase is controlled with the falling ON edge , The cylinder to be controlled on the bank is selected by an SPI Burst command prior to activation. It is suggested that a phase is started with the falling ON edge and that phase is ended with the rising edge.
