When EGR is on (YES in S100), an ECU selects a first map for the time when EGR is on as an intake air temperature correction map (S 102). Thus, an intake air temperature correction retardation amount α is set to an intake air temperature correction retardation amount αon (THa, KL) for the time when EGR is on, which corresponds to an intake air temperature THa and an engine load KL. On the other hand, when EGR is off (NO in S100), the ECU selects a second map for the time when EGR is off as an intake air temperature correction map (S 104). Thus, the intake air temperature correction retardation amount α is set to an intake air temperature correction retardation amount αoff (THa, KL) for the time when EGR is off, which corresponds to the intake air temperature THa and the engine load KL. |
