<P>PROBLEM TO BE SOLVED: To provide an internal combustion engine capable of reducing fuel costs, a CO<SB POS="POST">2</SB>emission amount, and an HC emission amount and improving travelability and driveability or the like of a vehicle. <P>SOLUTION: An ECU 50 of an internal combustion engine 10 learns a fuel injection amount correction coefficient for correcting a fuel injection amount of an in-intake-pipe-injection injector 36 on the basis of an in-intake-pipe-injection injector load-rotation speed learning area 65 and an in-intake-pipe-injection injector fuel amount-rotation speed learning area 80. The ECU 50 corrects the fuel injection amount of the in-intake-pipe-injection injector 36 using a fuel injection amount correction coefficient stored in a corresponding region of the in-intake-pipe-injection injector fuel amount-rotation speed learning area 80, in an in-cylinder-injection injector load-rotation speed learning area 66, and learns and stores the fuel injection amount correction coefficient of an in-cylinder-injection injector 35, in a plurality of divided regions obtained by dividing the in-cylinder-injection injector load-rotation speed learning area 66. <P>COPYRIGHT: (C)2012,JPO&INPIT |
