Abstract:
PCT No. PCT/AU93/00650 Sec. 371 Date Aug. 17, 1995 Sec. 102(e) Date Aug. 17, 1995 PCT Filed Dec. 14, 1993 PCT Pub. No. WO94/13949 PCT Pub. Date Jun. 23, 1994An 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 cylinder cycle marker circuit (16) 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 cylinder sequencer (22) for controlling the sequence of combustion in respective cylinders of the engine responsive to the engine cycle reference signal. A multiplying circuit (14) 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 (24, 26) 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 DEG 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.
