The North American automotive industry is presently facing the challenge of a recently signed energy bill increasing corporate average fuel economy standards to 35 mpg (6.7 L/km) by 2020, inclusive of cars and trucks. The passing of this bill is coincident with crude oil costs hovering in the 130 USD / barrel range, retail gasoline costs in the 4 USD / gallon range, and mounting evidence on CO2 emissions & global warming. Ford Motor Company has anticipated these trends, has invested in the development of fuel efficient engine technologies, and is now deploying these technologies in volume to deliver both a meaningful and sustainable response to the above challenges. Leading the deployment curve is a technology publically announced as EcoBoost, representing the application of direct fuel injection and turbocharging to an advanced gasoline engine. Ford has previously reported the fundamentals of this technology which enables a significant fuel economy improvement via engine downsizing, and a significant performance improvement via engine dynamic response. As applied to I4 & V6 engine architectures, Ford has announced plans to deploy up to 750000 EcoBoost engines worldwide by 2013 CY, with first application in the form of a 3.5L V6 EcoBoost engine in the 2010 MY Lincoln MKS luxury sedan. This paper summaries the development of the 3.5L V6 EcoBoost engine and its associated as-installed systems. Combustion, fuel, boost, and power conversion systems are discussed in detail with emphasis on the efficiency and value of these systems which enable a singular engine design to be applied across a wide range of applications. Engine performance and fuel economy assessments are also discussed and compared to conventional gasoline engines.
