<P>PROBLEM TO BE SOLVED: To reduce an emission, especially emission at a cold state in a control unit of an internal combustion. <P>SOLUTION: The control unit of internal combustion engine includes a port injector that jets a fuel into an intake port, a cylinder injector that jets the fuel into the cylinder, and a learning means that performs learning to obtain a learning value for correcting the fuel jetting amount in an operating area where the fuel is jetted at a predetermined jetting amount ratio from both the port injector and cylinder injector and the jetting amount ratios are different between the cold state and warm state. The learning means executes the learning for the cold state after temporarily shifting the jetting fuel amount ratio of the port injector and cylinder injector to that of the cold state, if the learning for the cold state is completed, a learning for the warm state is executed after returning the jetting fuel amount ratio of the port injector and cylinder injector to that of the warm state. <P>COPYRIGHT: (C)2012,JPO&INPIT |
