Abstract:
During rapid warm-up operation, a CPU executes full lift injection processing, in which a nozzle needle reaches a maximum lift amount, in an intake stroke of each cylinder of a four-cylinder internal combustion engine, and then executes partial lift injection processing, in which the nozzle needle does not reach the maximum lift amount, in a compression stroke. On the other hand, during learning of injection characteristics of partial lift injection processing, the CPU executes full lift injection processing after executing partial lift injection processing, both of which are executed within a predetermined period in an intake stroke. The CPU learns the injection characteristics based on an inflection point in the temporal change of the induced electromotive force in a coil following the end of the partial lift injection processing.

Claim (Index 2):
The fuel injection control device for an internal combustion engine according to  claim 1 , wherein\n the electronic control unit is configured to execute injection amount division processing that divides a required injection amount for the fuel injection valve into an injection amount for the partial lift injection processing and an injection amount for full lift injection processing that opens the fuel injection valve to the maximum lift amount, the electronic control unit is configured to, when having determined that a learning condition for the injection characteristic of the fuel injection valve is established, execute time division processing that operates the fuel injection valve so as to execute the full lift injection processing after executing the partial lift injection processing based on the injection amount division processing, and the electronic control unit is configured to, when executing the valve closing detection processing, set a fuel injection period of the partial lift injection processing and a fuel injection period of the full lift injection processing so as not to overlap with each other in the plurality of cylinders.
