摘要： PROBLEM TO BE SOLVED: To provide a control device for internal combustion engines capable of removing a deposit to prevent preignition (preignition at low speed) from occurring in a high-load region of low engine rotation in the control device for internal combustion engines.SOLUTION: As shown in Fig.4, whether preignition has occurred or not is determined (Step 100). When it is determined that the preignition consecutively occurs, it can be determined that the preignition is due to deposit, so, whether an operation region of an engine 10 is in a high-load region of low engine rotation or not is determined (Step 110). When the operation region is out of the high-load region of the low engine rotation, over-advance angle control is executed. On executing the over-advance angle control, ignition timing is advanced so that a maximum combustion pressure value subjected to averaging procedure Pmax can approach guaranteed pressure corresponding to a material strength guaranteed value for pistons.
