Ignition timing control device

Abstract

Abstract PURPOSE: To absorb a shock at the time of acceleration by delaying an ignition timing from an optimal ignition timing when a shift is made from a state of fuel cutoff to a state of acceleration and smooth an increase in generating torque on the engine. CONSTITUTION: A microcomputer 5 calculates an ignition signal through operation based on a signal emitted from angle sensor 1, load sensor 2, throttle switch 3 and fuel shutoff/detection means 4. Then the computer operates transistor 12 through opening/closing operation to make the latter ignite. In addition, the device detects the timing of reacceleration after fuel shutoff receiving a signal from throttle switch 3 and fuel shutoff/detection means 4. Then it delays ignition timing by a value corresponding to a fixed angle from an optimal ignition timing value or an ignition timing value. COPYRIGHT: (C)1981,JPO&Japio
