METHOD FOR ESTIMATING THE VOLUMETRIC EFFICIENCY OF AN INTERNAL COMBUSTION ENGINE

摘要

The method involves receiving dynamic parameters such as temperatures, pressures, and richness of an injected fuel, of an internal combustion engine. Variations of the received parameters are evaluated with respect to known reference parameters for one of nominal functioning points of the engine. A volumetric efficiency of the engine is calculated from the variations, speed of the engine and determined coefficients of the engine.
