Chronology
PredecessorFord Duratec engine

EcoBoost is a family of turbocharged and direct injected six-cylinder and four-cylinder gasoline engines produced by the Ford Motor Company. Engines equipped with EcoBoost technology are designed to deliver power and torque consistent with larger displacement, naturally aspirated engines while achieving approximately 20-percent better fuel efficiency and 15-percent reduced greenhouse emissions than these same engines. Relative to the power output and fuel efficiency of hybrid and diesel technologies, Ford sees EcoBoost as an affordable and versatile alternative and intends on using it extensively in future vehicle applications.[1] By 2012, the company plans to produce 750,000 EcoBoost units annually in the US and 1.3 million globally in the world market. Ford expects over 90-percent of its North American vehicle lineup to offer EcoBoost engine technology by 2013.[2]

EcoBoost V6

The first engine in the EcoBoost series is the V6. The engine first appeared in the 2007 Lincoln MKR Concept under the name TwinForce.[3] The engine was designed to deliver power and torque output equivalent to a typical 6.0L or larger displacement V8 while achieving at least 15% better fuel efficiency and reduced greenhouse emissions compared to the engine V8. In the MKR the concept TwinForce engine was rated 415 hp (309 kW) and Template:Auto ftlbf of torque, as well as run on E85 fuel.[4]

When the same prototype engine reappeared in Lincoln MKT concept in 2008 North American International Auto Show, the name was changed to EcoBoost.

The production engine uses the Duratec 35 V6 engine block, which also includes the Plasma Transferred Wire Arc (PTWA) thermal spray coating from the contemporary base block.[5] The fuel charging and delivery systems can attain high fuel pressures of up to 2150 PSI, necessary for efficient operation of the direct fuel injection system. It uses 2 Garrett GT15 turbochargers which can spin at up to 170,000 rpm and provide 12 PSI of boost. The engine can consume up to 25% more air over the naturally-aspirated counterpart. Through the use of direct injection, the engine needs only regular-grade gasoline to run, though premium fuel is recommended. The EcoBoost V6 was first available as engine option for 2010 Lincoln MKS, followed by 2010 Ford Flex, 2010 Ford Taurus SHO, and 2010 Lincoln MKT.[6]

The fuel charging and delivery systems were co-developed with Robert Bosch GmbH.[7]

These engines are being assembled at Ford Cleveland Engine Plant No. 1 in Brook Park, OH. [8]

Ford also built an experimental 3.5L GTDI EcoBoost engine modified with E85 direct injection and gasoline port fuel injection, which achieved a BMEP score of 305 psi (27 bar), which translates to approximately 553 pounds-feet of torque and 316-hp at 3,000 rpm (flat torque curve from 1,500 to 3,000 rpm).[9]

Applications

EcoBoost I-4

Ford has so far unveiled two different four-cylinder engines equipped with EcoBoost technology in concept vehicles. Like the 3.5L EcoBoost V6, both engines are turbocharged and direct injected. Ford will produce a new 2.0-litre and small-displacement version of Ford's EcoBoost advanced petrol engine in Ford Cologne Engine Plant, Ford Craiova Engine Plant and Ford Valencia Plant in Spain in 2009.

2.0L EcoBoost I-4

A 2.0L version was first found in the 2008 Ford Explorer America Concept.[1] The engine was rated Template:Auto bhp and Template:Auto ftlbf.

2.0L EcoBoost I-4 Ti-VCT

It is the first EcoBoost engine to include Twin-Independent Variable Cam Timing (Ti-VCT), with advertised 10-20% better fuel economy while maintaining the performance of 3.0 liter V6 engines. Power will be at least Template:Auto bhp, and torque will be at least Template:Auto ftlbf. Ford announced the production would begin in 2010.[10][11].

Applications

1.6L EcoBoost I-4

A 1.6L version was first unveiled in 2009 Lincoln C Concept. The engine is rated Template:Auto bhp and Template:Auto lbft.[12]

GTDI - Volvo named EcoBoost

Volvo dubs it GTDi for Gasoline Turbocharged Direct injection engine (debut 1.6 GTDi engine in Volvo S60 Concept) - mechanical clone of the new 1.6-liter four-cylinder Ford EcoBoost engine.[13]

EcoBoost V8

Main article: Ford Boss engine

A EcoBoost version of 6.2L DOHC 4-valve Boss engine.

Bobcat - Dual Fuel Engine

Codenamed Bobcat, it is an expansion to the EcoBoost family. It is based on a 5.0L V8 engine block, but it uses E85 cylinder injection and gasoline port injection. The engine was co-developed with Ethanol Boosting Systems, LLC of Cambridge, Massachusetts. The Bobcat project was unveiled in Department of Energy and Society of Automotive Engineers in April 2009.[14]
