<P>PROBLEM TO BE SOLVED: To provide an ignition timing control device which stabilizes combustion in a spark ignition internal-combustion engine including an EGR (Exhaust Gas Recirculation) device. <P>SOLUTION: The ignition timing control device (100) controls ignition timing relating to an internal-combustion engine (11) which includes an EGR device (22) that recirculates at least a part of exhaust gas, and which generates a spark with an ignition plug for combustion. The ignition timing control device includes a changing means (21) which changes annealing rate relating to annealing that gradually brings an advance angle amount of the ignition timing close to a target value in accordance with an intake air amount of the internal-combustion engine at the start of the EGR device. <P>COPYRIGHT: (C)2013,JPO&INPIT |
