Rapid engine mapping and modeling

摘要

A method of mapping and modeling an engine during an engine development process includes testing the engine over a plurality of actual engine operating conditions and gathering actual engine data corresponding to the actual engine operating conditions. A plurality of parameter functions are determined based on the actual engine data, each of the plurality of parameter functions correspond to an engine operating parameter. A plurality of combustion parameters are generated for a plurality of engine operating conditions that include the plurality of actual engine operating conditions and a plurality of virtual engine operating conditions. An engine simulation model is calibrated based on the plurality of combustion parameters and a plurality of engine maps are generated using the simulation model.
