Ford Motor Company has announced that the multiple award-winning 1.0L 3-cylinder turbocharged EcoBoost petrol engine would come with cylinder deactivation technology from early 2018. The technology would be a global first on a three-cylinder engine and it would stop or restart combustion in 14 milliseconds and improve CO2 and fuel efficiency by up to six percent. The EcoBoost engine develops a maximum power of 123bhp, while delivering a mileage of 19kmpl on the India-spec Ford EcoSport. The updated engine with new technology is expected to debut with the EcoSport facelift by early 2018 in the Indian market.
Cylinder deactivation will deliver reduced running costs for 1.0-litre EcoBoost customers by automatically stopping fuel delivery and valve operation for one of the engine’s cylinders in conditions where full capacity is not needed, such as when coasting or cruising with light demand on the engine. “Ford has pushed back the boundaries of powertrain engineering once again to further improve the acclaimed 1.0-litre EcoBoost engine, and prove that there is still untapped potential for even the best internal combustion engines to deliver better fuel efficiency for customers,” said Bob Fascetti, vice president, Global Powertrain Engineering, Ford Motor Company. The cylinder deactivation system is developed by Ford engineers at Dunton Technical Centre, in Essex, UK, Germany and the U.S. in collaboration with Ford’s engineering partners at the Schaeffler Group.
Simple in concept but featuring advanced engineering that enables it to operate at engine speeds of up to 4,500rpm – when valves are each opening and closing almost 40 times per second – the system uses engine oil pressure to activate a special valve rocker and interrupt the connection between the camshaft and the valves of cylinder number one. “With the variable capacity delivered by cylinder deactivation, drivers get the power and performance of the whole engine when they need it, and the enhanced fuel efficiency of a smaller engine when they don’t,” said Denis Gorman, powertrain engineer, Ford of Europe. “Our research shows that in most driving scenarios the system will be active for just a few seconds at a time, making fast and seamless operation crucial, and has the potential to improve fuel efficiency by up to six per cent.”
