<p><P>PROBLEM TO BE SOLVED: To provide a fuel injection control device capable of suppressing the deterioration of the fuel economy of an engine and reducing the unburned HC discharged from the engine. <P>SOLUTION: Since injectors 61, 62 are installed in intake ports 261, 262 communicating with a combustion chamber 28, respectively, the fuel injected from the injectors 61, 62 is prevented from being adhered to a wall part 34 which separates the intake ports 261, 262 from each other. A controller controls the injection amount of the fuel from the injectors 61, 62 according to the flows of the intake air flowing through the intake ports 261, 262. Therefore, any excess fuel is not injected from the injectors 61, 62 which inject the fuel into the intake ports 261, 262. Consequently, the excess fuel is prevented from remaining in the intake ports 261, 262, and the fuel in the form of liquid drops does not flow into the combustion chamber 28. As a result, the imperfect combustion of the fuel is suppressed. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
