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 7):
The fuel injection control device for an internal combustion engine according to  claim 1 , wherein\n the internal combustion engine further includes a fuel tank storing fuel to be injected by the fuel injection valve and a fuel pump configured to discharge the fuel in the fuel tank to the fuel injection valve side, the electronic control unit is configured to execute variable setting processing that variably sets a target value of a pressure of the fuel to be supplied to the fuel injection valve, the electronic control unit is configured to control the fuel pump so as to execute fuel pressure control processing that controls the pressure of the fuel to be supplied to the fuel injection valve to the target value set by the variable setting processing, and the electronic control unit is configured to execute injection amount variable processing that increases an injection amount of the partial lift injection processing, according to establishment of the learning condition, when the pressure of the fuel to be supplied to the fuel injection valve is high compared to when the pressure is low.
