Tuning of an internal combustion engine in the development by characteristic diagram optimization parameter domains high-dimensional

摘要

The invention relates to a method for the investigation of the behavior of an internal combustion engine, by means of the formation of a model for the characteristic diagram optimization of at least two parameters, in particular experimental parameters (n = a, b) of the internal combustion engine, which for the optimization of at least one target variable, in particular for the optimization of emissions and / or the consumption of the internal combustion engine. It is the steps are provided, determining (1) of the operating limits on the basis of measured data on a test stand by variation of at least one test parameter of the internal combustion engine; creating (2) of a experimental design with test points for at least one hand, to varying test parameters; detecting (3) of the measurement data for all according to a test planning to varying test parameters and all for the subsequent check the plausibility and subsequent modeling necessary measured variables on the test stand; verifying (4) of the plausibility of the measurement data of all test parameters and target parameters; forming (5) of at least one of the target variable describing the mathematical computer model; optimized (6) of the test parameters for the at least one target variable with the aid of the mathematical mathematical model on the target variable be described; verifying (7) of the according to the optimization (6) resulting optimal adjustment of the test parameters by measurements on the test stand.
