摘要：
A fuel injection correction coefficient for a first fuel injection valve and a second fuel injection valve with respect to a second fuel injection proportion in a second combustion is learned (step 107) in each of learning regions based on the fuel supply amount supplied into a cylinder, by carrying out a first combustion whose fuel injection proportion is set to the second fuel injection proportion, in the operation region of the second combustion (step 106).
