摘要： A method of controlling an internal combustion engine employs a microcomputer to control the fuel supply to the engine as well as the ignition timing thereof on the basis of measurement of the air quantity fed to the engine. For measuring the air quantity charged to the engine with high accuracy, the intake air flow fed to the engine is sampled in synchronism with the pulsating variation thereof. A value obtained by averaging the sampled values is used as the intake air quantity on the basis of which the fuel supply and the ignition timing are arithmetically determined.

摘要： A fuel injection control apparatus for controlling the amount and the timing of fuel injection with the aid of a microcomputer includes a hot-wire type flow sensor for detecting an instantaneous intake air flow velocity within an intake air passage of an internal combustion engine. The output signal of the hot-wire type flow sensor is sampled at every predetermined crank angle or at every predetermined time point to be stored in a RAM. The time at which the instantaneous velocity of the intake air flow within the intake passage becomes maximum is detected. The fuel injection timing of a fuel injection valve disposed in the intake passage is so controlled that the fuel injection is terminated around the time point at which the instantaneous intake air flow velocity is maximum.

摘要： A method of starting the operation of an internal combustion engine utilizes a turning force transmitted from wheels of a vehicle through a clutch in addition to a driving force generated by a starting motor. A computer for controlling engine operations detects the initiation of the engine starting operation on the basis of the rotating speed of the engine or intake air quantity and additionally detects the termination of the engine starting operation when the engine rotating speed or intake air quantity exceeds an associated reference value. When the engine stops in the course of running of a vehicle, the engine can be re-started under the influence of the inertial force of the vehicle without resorting to the operation of the starting motor.

摘要： An electric ignition control system for an internal combustion engine has a first pulse generator for producing pulses at each 180.degree. interval of crank shaft revolution, a second pulse generator for delivering a predetermined number of pulses, such as 1800 counts, during each 180.degree. interval, and a read only memory for producing a digital signal representing ignition timing in response to both engine speed and throttle opening. When the first counter circuit has counted the number of the second pulse generator pulses equal to the digital value of the digital signal from the memory, the primary current of an ignition coil applied from a battery to the primary coil thereof is interrupted for producing a high voltage to establish an ignition spark across the gap of a spark plug.
