Abstract
A method and system for controlling an internal combustion power train, whereby the values of various operating parameters of the power train are measured by means of a number of sensors, and operation of the engine is monitored by means of at least one control unit, which is physically separate from the engine block and connected to the sensors; at least one pressure sensor is housed in the control unit, is physically separate from the engine block, and determines the intensity of pressure waves generated by the power train; and the control unit determines the value of at least one operating parameter of the power train as a function of the intensity of the pressure waves generated by the power train.
