Startup Control Apparatus And Method For Internal Combustion Engine

摘要

In a spark ignition type internal combustion engine (11), automatic stoppage and automatic startup are executed under predetermined conditions, and a fuel cut is executed when an engine rotational speed exceeds a reference rotational speed that is higher than a target idle rotational speed (Ni) at the beginning of the automatic startup. An electronic control apparatus executes ignition timing variable control during startup of the internal combustion engine (11) such that an ignition timing of the internal combustion engine (11) is retarded when the engine rotational speed is increasing and advanced when the engine rotational speed is decreasing. Further, the electronic control apparatus prohibits the ignition timing variable control for a predetermined time following the beginning of startup of the internal combustion engine (11), and the predetermined time during which the ignition timing variable control is prohibited is set to be longer during automatic startup of the internal combustion engine than during manual startup.
