The New “Torque Strategy” For The Control of The Spark Ignition Engine. Development of a Motorized Butterfly Valve Through Experimental Techniques and Computational Modelling

In this paper a torque strategy used by RENAULT for the control of a spark ignition engine is presented. With this new strategy for engine control, it was necessary to develop a new motorized butterfly valve. The design and development of this element is described in the paper. This research was carried out through the application of both modeling techniques using computational tools and experimental techniques on the steady flow rig and the engine bench.
