AbstractA high-power density, low specific heat rejection diesel engine design for traditional and hybrid future combat system (FCS) vehicle configurations is being proposed. The total propulsion system of the vehicle hybrid configuration will fit the future vehicle assigned space/volume by TACOM's vehicle concept laboratory. The proposed engine will have a high-pressure common rail fuel injection system, additional electronic power kit, and two turbochargers to increase the intake boost pressure, and to decrease the exhaust gas temperature at full load and various speeds. The two turbochargers will be controlled by two electronic sensors, which will control the flow of the exhaust gas trough the exhaust port of each turbocharger. These two sensors are affected by the engine exhaust gas temperature, and engine speed. The engine parts will be coated with tribological and thermal barrier coatings to reduce the friction and wear between the rotating and sliding engine parts, and to reduce the heat rejection to the coolant and to the ambient. The engine test will be run to determine engine performance, and engine endurance. The Massachusetts Institute of Technology-Adiabatic, and National transport University-Adiabatics mathematical computer programs, and modeling/ simulations graphic use interface will be used in this program to determine the engine parameters. The simulation modeling, computations and layout design will include the concept of modular designs of the total propulsion system components as cooling system, fuel injection system, lubricating system, and turbocharger system.
