Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an ignition timing control device for an internal combustion engine capable of increasing an engine output by appropriately controlling the ignition timing of the engine having a throttle valve disposed near an intake valve and expanding a knocking limit to an advancement direction. SOLUTION: A base target value IGTHCMNDK is calculated according to engine speed Ne, a throttle valve opening TH and an intake valve operation phase CAIN, and a target value IGTHCMD is calculated by multiplying the base target value IGTHCMDK by a correction coefficient KIGTHPA according to atmospheric pressure PA (S21-S23). A throttle valve opening correction term IGTH is set to coincide with the target value IGTHCMD (S26, S32-S34). Ignition timing IGLOG is calculated by correcting base ignition timing IGM by the throttle valve opening correction term IGTH. COPYRIGHT: (C)2010,JPO&INPIT
