  • Publication number: 20090222195
    Abstract: At each engine cycle, nearby the TDCC, an injector is driven so as to perform a fuel injection sequence according to a predetermined pattern (A-Z), including a plurality of successive, separate fuel injection pulses (pulse 1-pulse N) having respective predetermined durations. The start of the first injection pulse (Pulse 1) of the sequence is defined as a predetermined angular distance from the TDCC. For each injection pulse (pulse 2-pulse N) following the first one (pulse 1) the respective start is selectively determined either as a time distance from the end of the immediately preceding injection pulse (pulse 1-pulse N?1) or as an angular distance from the relevant TDCC, in dependence on the instantaneous value of at least one predetermined parameter.
