Soft-computing method for establishing the heat dissipation law in a diesel common rail engine

摘要

The invention relates to a soft-computing method for establishing the dissipation law of the heat in a diesel Common Rail engine, in particular for establishing the dissipation mean speed (HRR) of the heat. The method provides the following steps: choosing a number of Wiebe functions whereon a dissipation speed signal (HRR) of the heat is decomposed; applying a Transform PSI to the dissipation speed signal (HRR) of the heat; carrying out analysis of homogeneity of the Transform PSI output; realising a corresponding neural network MLP wherein the design is guided by an evolutive algorithm; making learn and testing the neural network MLP.
