<P>PROBLEM TO BE SOLVED: To provide an internal combustion engine capable of improving output torque when fuel is injected from both of a port fuel injection device and a direct injection fuel injection device during one cycle. <P>SOLUTION: In the internal combustion engine provided with the port fuel injection device 10a-10d injecting fuel to intake ports 6a-6d and the direct injection fuel injection devices 11a-11d directly injecting fuel in combustion chambers 5a-5d, a control device 16 including an ignition timing control function performing ignition at least twice at different timing when fuel injection from the port fuel injection devices 10a-10d and fuel injection from the direct fuel injection devices 11a-11d are performed in one cycle is provided. In this case, it is preferable to establish an ignition timing control function to ignite air fuel mixture created by port injection fuel at ignition timing suitable for the air fuel mixture first and then ignite air fuel mixture created by direct injection fuel at ignition timing suitable for the air fuel mixture. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
