<P>PROBLEM TO BE SOLVED: To restrain variation in an air-fuel mixed state even when a plurality of intake valves are provided. <P>SOLUTION: Fuel injection valves 18a, 18b are individually controlled to inject fuel according to the lift amount of the intake valve 17b, the fuel is injected so that when the lift amounts and lift timing of two intake valves 17a, 17b are individually controlled, the optimum air-fuel mixture is obtained, and even when two intake valves 17a, 17b are provided, variation in the state of air-fuel mixture is restrained to improve fuel economy and exhaust emission performance. <P>COPYRIGHT: (C)2010,JPO&INPIT |
