摘要： A digital control system for an internal combustion engine uses a two stage register. The register is used to store digital data representative of sensed engine operating conditions and to feed such data to a programmable digital computer for processing. Processing time is improved by reading only one register containing the most significant data bits of the stored data for engine parameters having a relatively narrow dynamic range and reading both registers, containing all data bits of the stored data for engine parameters having a relatively large dynamic range.

摘要： In an engine speed sensing device, angle pulses produced when the crankshaft rotates through a predetermined angle are counted by a counter for a predetermined interval. The count of angle pulses is read into a central processing unit of a digital computer at the end of each set time interval in response to a control signal which both updates the angle pulse count and signals the processing unit to read the count.

摘要： A fuel injection control device includes a microcomputer which determines a fuel injection amount based on the engine operation parameters. The microcomputer also actuates the fuel injection valve to open earlier in relation to the normal timing of fuel injection in response to turning on the starter switch. The fuel injection amount corresponds to the duration of opening of the fuel injection valve, and the opening duration of the fuel injection valve is defined by a driving signal and a stopping signal. The driving signal is generated at given angles of crank revolution. The driving signal is generated in response to a preset number of crank angle pulses, which is varied between the first fuel injecting operation and subsequent fuel injecting operations. The fuel injection timing of the first injecting operation is shorter than that of the remainder for improving start-up characteristics of the engine responsive to turning on the starter switch.

The digital control system comprises means for examining the length of pulse intervals of the engine speed signal and discriminating means for forming a judgement that the engine is stalling when the pulse intervals continue to be longer than a predetermined length of time for a predetermined period of time, so that the system does not misjudge the presence of a noise signal to be an indication of engine stall.

Intermittnetly cutting off the fuel delivery for the engine cylinders, engine output torque drop at the fuel injecting state and fuel cut-off state can be reduced for reducing magnitude of jerking.
