Abstract
PURPOSE: To prevent the ignition time from changing drastically and stabilize the run of an engine, by determining next ignition time calculated depending on the state of the engine in relation to the preceding ignition time.
CONSTITUTION: An angle detector 1 is attached to the distributor shaft of the four- cylinder four-cycle internal combustion engine to generate four reference signals at a uniform angular spacing and seven hundred and twenty angle signals per revolution. A pressure detector 2 detects the intake negative pressure of the engine. An ignition time calculator 3 is connected to the angle detector and the pressure detector and determines the ignition time depending on the state of the engine to supply an output to an igniter 4 which ignites the cylinder of the engine at the calculated ignition time. The calculator 3 determines the appropriate ignition time in relation to the preceding ignition time stored in a memory means.
