Device for the centralized management of measurements and data relating to the liquid and gas flows needed for the operation of a combustion engine

摘要

The invention relates to a device for the centralized management of measurements and data relating to liquid and/or gas flows needed for the correct operation of a combustion engine controlled by an engine computer and/or of a vehicle, said device comprising means for analyzing at least two liquid and/or gas flows including at least one light source, at least one optical signals detector and at least one system for analyzing the detected signals. At least one of said analysis means is used to analyze two of said flows. In this way, this device minimizes the bulk and added mass incurred by the analytical methods employed to analyze the various flows and simplifies the management of such a system.
