ABSTRACT:
Information relating to relative fuel pump camshaft advance angle is compared with a SOC signal indicative of the start of combustion in a reference cylinder to generate an adaptive trim table which is used, in a first control scheme to calculate an actual combustion angle for closed loop control over combustion timing only in the event of a loss of the SOC signal. In an alternate control scheme, the values from the adaptive trim table are always used to calculate the actual combustion angle for closed loop control.
