the result of ECU calculation is translated into a new set of electric signals transmitted to the actuators, which determine engine behavior [3,5]. Mechatronic systems ensure benefits compared with merely mechanical frameworks, including higher engine performance and reduced risks for engine damages [6]; such systems are also able to adapt the fuel injection strategy according to the current state of the engine, taking into account, for example, the warm-up phase or the regeneration of particulate traps [5].
