We consider a spark-ignition engine equipped with VVT actuators. This paper is an extension of a previously studied control technique (considered under atmospheric conditions). We show that the same control strategy boosts the torque production using VVT actuators under turbocharging conditions. At the light of reported experimental results, we stress the performance of the proposed control law and prove its theoretical beneficial effects.
