This crucial issue means air path evolutions with complex systems including advanced technologies such as Variable Valve Actuation (VVA) or two-stage turbocharging, and engine control capability improvement to optimise accurately the engine behaviour under transient conditions. At this stage of complexity, the engine controllability becomes a first-order factor to be taken into account in the technological orientations. Thanks to a high versatility of engine architecture, good physical trend capabilities and easy coupling with engine control, 0D simulation offers a very interesting support to help such investigations and discriminate the best Diesel air path system solutions. This paper describes how simulation is becoming a key tool to develop the control for various Diesel air path systems before having the corresponding experimental bench available, in order to anticipate the hard issues and begin to assess the controllability of each air path technology at the early stages of the engine development process. 3 Oil and Gas Science and Technology 64 ARTICULO Albrecht, A. 41725 Grondin, O. 41728 Schmitt, J.C. 41729 170258 170258 0 0 0 0 238077 BAAB BAAB 2026-03-05 200045085 0 200045085 2026-03-05 15:12:31 2026-03-05 ARTICULO
