<p>#CMT# #/CMT# 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. #CMT#USE : #/CMT# Method for estimating volumetric efficiency of an internal combustion engine of a vehicle to control the engine. #CMT#ADVANTAGE : #/CMT# The method permits to know the volumetric efficiency and breathing characteristics of the internal combustion engine, irrespective of the functioning point of the engine, thus controlling actuators such as exhaust gas recirculation unit's valve, of an air loop of the engine. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a block diagram illustrating a volumetric efficiency estimating method.'(Drawing includes non-English language text)'.</p> |
