METHOD AND SYSTEM FOR GENERATING A FUEL PULSE WAVEFORM

摘要

A method and system for generating a fuel pulse output signal to control fuel delivery from a fuel injector to a cylinder of an internal combustion engine. A plurality of holding registers (42) asynchronously receive a plurality of fuel pulse data from a processor. The plurality of holding registers (42) are memory-mapped and store the plurality of fuel pulse data until subsequent fuel pulse data is received from the processor. A plurality of match registers (46) are coupled to the plurality of holding registers for comparing the fuel pulse data with a reference signal and generating a fuel pulse output signal based on the comparison between the fuel pulse data and the reference signal.
