摘要： In an ignition control system for the internal combustion engine, a reference angle sensor detects the rotational speed of the internal combustion engine, and detects a point near the top dead center, and generates a reference angle signal. An angle sensor similarly detects the rotational speed of the internal combustion engine, and discriminats the rotational speed for each predetermined angle, and generates an angle signal. A microcomputer includes an output compare register, a free-running counter and a timer control status register, and computes the ignition timing and energization time of the ignition coil in response to a reference angle signal from the reference angle sensor and an angle signal from the angle sensor.

摘要： Energizing interval of an ignition coil, which is basically determined on the basis of the rotational speed of an engine, is corrected by adding thereto an extension amount which is either a function of the rotational speed of the engine or a given upper limit value at the rotational speed of the engine when accelerating condition is detected. Thus, the ignition coil is supplied with a primary winding current for a desired interval even during acceleration so that sufficient ignition voltage will be produced to properly ignite air/fuel mixture in engine cylinders. The extended energizing interval is then reduced stepwise to provide normal energizing interval during engine operations other than acceleration.
