Ford confirms 2012 launch for 1.0-litre EcoBoost
Ford has confirmed the first production applications for its three-cylinder, 1.0-litre EcoBoost engine. It will make its debut in the Focus, followed by the C-Max and B-Max.
Two versions of the 1.0-litre engine will be introduced in the Focus in Europe in early 2012 with 100PS and 120PS, fitted with five-speed and six-speed manual transmissions respectively. The engine will also be made available in Ford models in North America, China and other regions.
“By offering the Focus with an advanced small-displacement petrol engine Ford is not only making a major statement on how serious we are about engine downsizing – it also shows the strength of our development and engineering capabilities. To produce a 1.0-litre 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 Ford of Europe's powertrain boss Graham Hoare.
Compact turbocharger provides rapid response
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 turbocharger and its ability to reach nearly 250,000rpm is said to virtually eliminate turbo lag. The 120PS variant delivers peak torque of 170Nm from 1,300rpm to 4,500rpm.
The all-new EcoBoost engine also features an exhaust manifold cast into the cylinder head, which lowers the temperature of the exhaust gases and in turn enables the engine to run with the optimum fuel-to-air ratio across a wider rev band.
A “split cooling” system reduces fuel consumption by warming the engine more quickly. Unlike the larger EcoBoost engines the block is cast iron, which is said to reduce the amount of energy needed for warm-up by up to 50 per cent compared with an aluminium block.
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.
Like its larger capacity siblings, the 1.0-litre EcoBoost engine 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.
Drive belts run in oil and flywheel is 'unbalanced' to improve refinement
The two main engine drive belts are immersed in oil, which is said to result in quieter and more efficient running with the durability of a chain drive. Instead of using balancer shafts, Ford has deliberately “unbalanced” the flywheel and pulley to reduce the overall vibration of the engine.
“The 1.0-litre EcoBoost is one of the most advanced engines Ford has ever produced and makes use of so many innovative techniques and technologies that it’s difficult to keep count” said Hoare. “It has always been Ford’s strategy with EcoBoost technology to look at every single detail in our relentless pursuit of improving fuel economy without compromising performance, and this new engine demonstrates that philosophy perfectly. The net result is an engine that we’re sure will surprise and delight our customers.”
