The combustion of 1 liter of diesel fuel produces approximately 11% more energy than gasoline fuel, but the diesel fuel also releases approximately 11% more CO2 due to its higher carbon content. On top of the higher energy density of diesel fuel, diesel engines historically possessed a number of efficiency advantages over gasoline engines.
