Patent

CA 2151839

An electronic timing system for producing precise timing control signals to the fuel injectors and ignition coils of an internal combustion engine. The system includes a means for generating an engine cycle reference signal based on the detected operational position of the engine as indicated by a TDC signal and a fly wheel teeth (FWT) signal. The system also includes a means for controlling the sequence of combustion in respective cylinders of the engine responsive to the engine cycle reference signal. A multiplying circuit in the form of a phase lock loop (PLL) circuit is provided for multiplying the incoming FWT signal to produce a high resolution engine rotation signal which is a programmable integer multiple of the FWT signal. Injector and ignition timing control signals can be delayed by timers with a programmable delay specified in terms of an integer multiple of the multiplied FWT signal, and can therefore be precisely set in terms of crank angle before TDC regardless of the engine speed. Furthermore, being angle referenced each programmable delay at least maintains the last calculated advance setting regardless of changes in engine speed.
