초록 ▼

The previous ignition timing is used as a starting point for repititive ignition cycles to define the primary coil current flow starting point, in order to secure a sufficient current flow duration for the primary coil current that is supplied to an ignition coil to thereby prevent a shortage of ignition energy. An arithmetic circuit including a central processor produces data representing the duration between the previous ignition timing and the primary coil current flow starting point. A counter starts this counting operation from the previous ignition timing. The primary coil current feed to the ignition coil starts at a time when the contents of the counter are coincident with the result of the processor produced data. The data is obtained by subtracting a necessary primary current flow duration or time from the interval between the previous ignition timing and the present ignition timing.

A method of operating a processor-controlled apparatus for controlling the operation of a combustion engine, said engine including an output shaft driven by mechanical energy converted from heat energy caused by the combustion of fuel, said engine including a source of electrical energy, ignition means, coupled with said source, for cyclically storing energy supplied from said source and discharging energy to be employed for combustion of fuel, detecting means, coupled to said engine output shaft, for producing a reference signal in response to a predetermined angle of rotation of the engine output shaft, and sensor means for producing signals representative of operational conditions of the engine, said method comprising, for each cycle of operation of said ignition means, the steps of: (a) generating a first signal in response to which said ignition means begins the storage of energy from said source and causing said ignition means to store energy for a prescribed charging duration, and (b) generating a second signal in response to which said ignition means discharges energy stored thereby so as to cause the combustion of fuel in said engine, the time interval from the generation of said second signal to the generation of said first signal corresponding to a predetermined period of time that energy is not being stored by said ignition means, and wherein step (b) comprises the step of: (b1) in response to a reference signal from said detecting means, generating first data, the value of which is successively changed from a first prescribed value until the value of said first data corresponds to a value representative of the time at which said second signal is to be generated, and thereupon causing the generation of said second signal, and wherein step (a) comprises the step of (a1) in response to the value of said first data corresponding to the value representative of the time at which said second signal is to be generated in step (b), generating second data the value of which is successively changed until the value of said second data corresponds to a value representative of the time at which said first signal is to be generated, and thereupon causing the generation of said first signal, and wherein, for successive cycles of storage and discharge of energy by said ignition means, step (a) further comprises the step of (a2) generating the value representative of the time at which said first signal is to be generated by: (a2-1) generating third data representative of the interval between the time of occurrence of said second signal for a present cycle and the time of occurrence of said second signal for the previous cycle, (a2-2) generating fourth data representative of said prescribed charging duration, and (a2-3) generating fifth data representative of the time interval from the generation of said second signal to the generation of said first signal in accordance with the difference between said third and fourth data, and wherein step (a1) comprises the step of (a1-1) generating said first signal in response to the value of said second data becoming equal to or greater than the value of said fifth data.
