ABSTRACT:
A method is described for controlling fuel injection in an spontaneous ignition engine equipped with an electronically controlled fuel injection system and with an electronic control unit receiving engine quantities comprising the pressure in the combustion changer of the engine and closed-loop controlling the fuel injection system on the basis of the pressure in the combustion chamber, in which the pressure in the combustion chamber is determined as a function of engine kinematic quantities such as the engine speed and the crank angle and of the fuel injection law, which is defined by the quantity of fuel injected and by the crank angle at the start of injection.
