Zusammenfassung:At the time of increasing an actual intake air amount by increasing a valve overlap period of intake and exhaust valves (2; 3), an actual compression ratio is temporarily decreased to be lower than a steady-state target compression ratio. This makes it possible to increase the valve overlap period without causing interference of the intake and exhaust valves (2; 3) with a piston (8).
