heal.abstract	A comprehensive computer program is used to simulate the unsteady gas flow in the exhaust and inlet systems of a six-cylinder, marine duty, turbocharged, aftercooled, medium-high speed, indirect injection, four-stroke diesel engine which is installed at the authors' laboratory. The simulation assumes one-dimensional, time varying, gas flow in the engine pipes and incorporates numerous realistic thermodynamic and heat transfer features. The characteristics mathematical transformation solution, of the gas flow dynamics partial differential equations, is interfaced with first law analysis models of the cylinders main chambers and prechambers, while the engine turbocharger system is simulated in both an efficient and low computer-time cost manner. The simulation results compare favourably against the engine's performance experimental results, which include mean air consumption rate, pressure histories at various locations on the exhaust system, and energy-mean temperature values at the exit of the exhaust system. The simulation results are also utilized for the determination of the various cylinders exhaust waves intensity, as they are imposed by the design characteristics of the exhaust manifold. The plotting of relevant charts, showing the contour variations of gas pressure, temperature and Mach index against engine crank angle and pipe length, aids in the correct interpretation of the observed behaviour.	en
