The resulting higher BMEP levels allow downsizing of the engine at equivalent vehicle performance. Furthermore, by enabling higher CR, downsizing and downspeeding, E85 DI + gasoline PFI makes the engine more efficient in itsusee of gasoline. Earlier post.) Stein et al. Bromberg, J.B.
This is because the ethanol component may affect the conversion efficiency of the gasoline component in a blend, that is, make an engine more or less efficient in its use of the gasoline component. converted all vehicle efficiency measurements into vehicle energy efficiency (VEE, km/MJ) based on fuel energy densities reported in each study.
Traditionally, this has been challenging but this combustion process results in ultra low emissions and has been achieved over a wide range of engine operating conditions, even from cold start. Emissions results are 20 ppm NO x at less than 2.3 bar load and has four-stroke-equivalent hydrocarbons and carbon monoxide emissions.
Ford’s turbocharged, gasoline direct injection EcoBoost engines are targeted to play a significant near-term role in Ford’s efforts to reduce fuel consumption by enabling downsizing.
