With only three-cylinders and 1.0 liter of displacement, the new EcoBoost engine will provide fuel-efficient power for three models in the European product range – first the Focus, followed by C-MAX and the all-new Ford B-MAX.
The new 1.0-liter engine is the latest addition to Ford’s global family of EcoBoost engines, which currently range in capacity from 1.6 to 3.5 liters globally.
Downsized EcoBoost engines feature turbocharging, direct injection and other technologies and replace larger engines with no loss of performance and with lower consumption.
Ford will introduce two versions of the 1.0-liter engine in the European Focus in early 2012, with 100hp and 120hp as well as five- and six-speed manual transmissions respectively.
Ultimately, this all-new engine will be made available in Ford models in North America, China and other regions.
“By offering the Focus with an advanced, small-displacement gasoline engine, Ford is not only making a major statement about downsizing – it also shows the strength of our development and engineering capabilities. To produce a 1.0-liter EcoBoost petrol engine with such impressive performance and fuel economy is a clear example of our commitment to be class-leading in fuel economy,” said Graham Hoare at Ford of Europe.
Despite its small capacity and proportions, the design delivered power and performance to rival a traditional 1.6-liter engine while emitting less than 120g/km CO2 in the Focus.
Developed at Ford’s Dunton Technical Centre in the UK, this direct-injected EcoBoost engine features a new compact, high-performance turbocharger design. The extremely fast response of the turbo and its ability to reach nearly 250,000rpm results in virtually no lag and peak torque of 125 lb-ft from 1300-4500rpm in the 120hp variant.
The all-new engine also features an exhaust manifold cast into the cylinder head, which lowers the exhaust gas temperature and, in turn, enables the engine to run with the optimum fuel-to-air ratio across a wider rev band.
An advanced “split cooling” system reduces fuel consumption by warming the engine more quickly and – unlike the larger EcoBoost engines – cast iron has been selected for the block, reducing the amount of energy needed for warm-up by up to 50 per cent compared with aluminum.
Intelligent ancillaries such as a variable air-conditioning compressor and oil pump also reduce demand on the engine – improving economy and emissions – while special coatings for engine components and intricate development of engine geometry result in minimal frictional losses.
Ford Auto-Start-Stop, Active Grille Shutter and Ford Smart Regenerative Charging will also be available as part of the Focus and C-MAX 1.0-liter EcoBoost package.
Like its larger capacity siblings, the 1.0-liter EcoBoost will use Ti-VCT twin variable camshaft timing to further improve performance and economy. Ford has also employed an all-new camshaft actuator to speed up response times without sacrificing durability.
Rather than employ the traditional method of adding energy-draining balancer shafts, Ford engineers have deliberately “unbalanced” the flywheel and pulley to offset the engine configuration. Ford believes these innovations combined with optimized engine mounts will deliver refined performance during 450,000 miles of tests.
