Continually increasing the maximum specific power output of engines used in military vehicles is vital to maintaining a battlefield advantage. An enabling technology for power optimization on existing engine architectures is advanced engine control based on real-time feedback control of the combustion. An engine equipped with intelligent controls and multi-fuel capable components has been used to demonstrate power improvements based on feedback control of the fueling by means of in-cylinder pressure measurements. In addition to optimized power output for the engine, the technology suite provides the capability to utilize both standard diesel fuel and alternatives such as jet fuel, biodiesel, or any mixture. A cylinder-balancing algorithm adjusts the fueling to achieve even power distribution between cylinders for improved performance and durability, or to operate all cylinders at the cylinder pressure limit when maximum power is required.
