heal.abstract	The measured pressure-crank angle diagram provides a valuable source of information concerning the performance of a diesel engine. In the present work a method is proposed for the determination of a model's constants based on the comparison between the measured (experimental) and calculated pressure diagrams. The top dead center of the engine is determined thermodynamically by a proposed model, with a reasonable accuracy. Therefore the advantage of a time reference for the measured pressure-crank angle diagram is provided. Due to this fact, one can also calculate the indicated power output of the engine using only one measuring device, i.e., a piezoelectric transducer. It is then also possible to calculate the initial pressure at inlet valve closure, using a suitable mathematical procedure based on the compression curve of the measured diagram, therefore bypassing the disadvantage of measuring errors associated with low pressures (less than 2 bar). After having determined the model's constants, one can proceed to the simulation, with acceptable accuracy, of the entire engine cycle.	en
