In the present work an approach to simulate and predict the flow characteristic in the intake and the exhaust manifolds of a six-cylinder four-stroke turbocharged diesel engine using GT-POWER and FORTRAN, for steady-state simulation. The simulation model covers the full engine cycle consisting of intake, compression, power and exhaust. The simulation and the prediction shown the diesel engine intake and exhaust manifolds parameters based on the crank angle degree. The results of the engine performances as well as pressure, temperature and mas flow rate in the intake and exhaust manifolds obtained by the developed program in language FORTRAN using the method of filling and emptying are presented. The commercial GT-Power software is used to the results validation. The range of variation of the rotational speed of the diesel engine chosen extends from 800 rpm to 2100 rpm.
