Numerical simulation of a Diesel engine in railway traction using partial differential equations

The paper integrates in the today´s trend, for the use of partial derivatives, in modeling and numerical simulation of the distributed parameters processes and systems. It is presents, in a simplified version, a study case based on the matrix with partial derivatives of the state vector (M_dpx), associated with Taylor series, for modeling and numerical simulation of a Diesel engine for railway traction, with rated power P_Dnom = 1,7 MW and rated rotation speed n_nom = 1800 rot/min. There are exposed and commented the computer results, emphasizing the advantages, disadvantages and limitations of the proposed method.
