Patent ID: 7418941

Claim:
A fuel injection apparatus comprising: a fuel injection arrangement for delivering a fuel injection pulse sequence to a combustion chamber during a combustion cycle, the fuel injection pulse sequence comprising a plurality of discrete fuel injection pulses, each discrete fuel injection pulse having a fuel injection pulse type; a calculation module for monitoring a plurality of vehicle operating parameters, calculating a fuel injection mode in response thereto, and determining a fuel injection mode identifier; and a controller arranged to receive the fuel injection mode identifier from the calculation module and operate the fuel injection arrangement in response thereto; wherein the fuel injection mode identifier comprises a plurality of markers, each of the plurality of markers having an ordinal number and a value, wherein the ordinal number of each marker is indicative of the sequential position of an associated one of the plurality of the discrete fuel injection pulses within the fuel injection pulse sequence, and the value of each marker is indicative of the fuel injection pulse type of said associated one of the plurality of discrete fuel injection pulses.
