Study finds hitting thermodynamic sweet spot in dilute, boosted gasoline engines has potential for fuel economy gains between 23% and 58%

Green Car Congress

A study by a team led by Dr. Dennis Assanis at the University of Michigan suggests that accessing the “thermodynamic sweet spot” in high-efficiency, dilute, boosted gasoline engines has the potential for vehicle fuel economy gains between 23% and 58%. Their paper is published in the International Journal of Engine Research.
