Abstract
Control of a quantity of air introduced into an intake of a supercharged internal combustion engine which includes a proportional valve located in a partial transfer duct which controls flow of compressed air flow through the partial transfer duct into an inlet of a turbine. The proportional valve is controlled to move between open and closed positions in accordance with strategies in accordance with stabilized phases of operation of the engine. Characteristics of stabilized phases of operation of the engine are determined and are used to control circulation of the compressed air during transitions between the stabilized phases of engine operation in accordance with the determined characteristics of the stabilized phases of the engine operation. The determined characteristics are derived from a previously completed mapping of speed and charging of the supercharged engine during a previous stabilized phase.
