<p><P>PROBLEM TO BE SOLVED: To provide a fuel injection control device and a fuel injection control system capable of accurately controlling injection mode of a fuel injection valve in more engine situations. <P>SOLUTION: Fuel injection mode of the engine 10 provided with a cylinder pressure sensor 12a measuring pressure in each cylinder on all four cylinders 12 are controlled. The fuel injection control device (engine control ECU 30) is provided with a program for measuring pressure in the cylinder (cylinder pressure) based on output of the cylinder pressure sensor 12a when fuel to be used for combustion is additionally injected and supplied into the cylinder during fuel combustion in each object cylinder with individually setting the four cylinders 12 as an object (for example, in execution of after-injection), and a program variably controlling command signal (pulse width) to an injector 24 relating to the object injection (after-injection) based on the measure cylinder pressure (actual measured value). <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
