Abstract: A Common Rail injection system of an endothermic engine, the injection system including at least one fuel pressure accumulating tank, of the rail type, having an input in fluid communication with a high-pressure pump and a plurality of outputs for feeding corresponding injectors by using pressure regulating means connected and depending on an electronic control unit. Advantageously a virtual pressure sensor includes a fluid-dynamic model of the accumulating tank suitable to estimate and to obtain fluid pressure values used by the electronic control unit for driving the injection means of the Common Rail injection system.

Abstract: An injection control method for controlling a nullcommon railnull fuel injection system in a diesel engine is described. The method includes the following steps: an initializing step for acquiring engine control parameters; and a main adjustment cycle for adjusting operational variables of the engine. The injection control method also includes an interrupting step for adjusting an injection procedure proper of the injection system by variation of all the characteristic parameters of the injection procedure. Also described is an injection control system for a diesel engine based on the above method.
