    摘要: An altitude decision system and engine operating parameter control system using the same for accurately detecting and correcting for altitude uses three signals, viz, the signal from an engine revolution number sensor (52), the signal from a throttle sensor (18) for detecting the angle of opening of a throttle valve (5), and a fundamental fuel injection pulse width signal which is computed by engine operational parameter-computer (51) from inputted signals from a mass air flow sensor (3) and the revolution number detection sensor (52). Having accurately derived the altitude, the fuel injection pulse rate (61), the intake air flow (62) and the ignition timing (63) are corrected.

    摘要: The invention relates to a method and a device for controlling the ignition timing of internal combustion engines, wherein the detection processing of the rotational speed (N) of the engine is executed periodically in synchronism with the rotation of the engine. The calculation processing of an ignition timing correction amount (ΔIGN) is executed periodically at predetermined fixed times independently of the rotational speed detection processing. After the engine is accelerated, the ignition timing control of the engine is executed based on the ignition timing correction amount.
