Abstract
The method comprises receiving from the vehicle controller, values associated with the engine speed and of another parameter indicative of the engine operating conditions, such as the total fuelling amount, and controlling the fuel injection parameters according to the engine state, which, for example, can include a normal operation mode, a filter regeneration mode, an engine protection mode, high or low transient load modes, and operating at different altitudes, through algorithms implemented in an electronic controller.
