<P>PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine capable of sufficiently restricting adhesion of fuel to the inner surface of a cylinder, improving the degree of freedom in setting of fuel injection period. <P>SOLUTION: This control device includes: a first injector 13 for injecting fuel into a cylinder 2; and a second injector 14 for injecting fuel into an intake port 3a, and controls injection share ratio of the injection amount of each of the injectors 13 and 14 in response to alcohol concentration in the fuel. The control device, further, includes an oil jet device 11 for injecting oil to a back surface of a piston 5. In the case wherein the temperature of an internal combustion engine 1 is a predetermined temperature or less and the injection share ratio is controlled so that the injection amount of the first injector 13 is controlled to be the minimum injection amount or less, a stop period is set based on the alcohol concentration of the fuel, and injection of the oil from an oil jet device 11 is stopped for the set stop period. <P>COPYRIGHT: (C)2011,JPO&INPIT |
