Ford develops cylinder deactivation for EcoBoost engine

Ford has broken new ground by becoming the first car manufacturer to develop cylinder deactivation technology in a three-cylinder engine.

Ford customers will be able to specify the 1.0-litre EcoBoost petrol engine with the new system from 2018. The technology shuts down one of the unit’s three cylinders when the engine is not under load. This allows for better economy and efficiency, without having to reduce the engine’s power output.

The American manufacturer claims that the system works almost imperceptibly to the driver, as the cylinder can disengage and re-engage in 14 milliseconds - 20 times faster than the human eye can blink. Engineers have worked to make the change from two- to three-cylinder modes as refined as possible.

According to Denis Gorman, a powertrain engineer at Ford of Europe, the system will only work for a few seconds at a time, but still “has the potential to improve fuel efficiency by up to six per cent.”

Volkswagen Group cars, including the Seat Ibiza and Audi A1 have featured similar technology for some time, but have only been applied four-cylinder engines.

Bob Fascetti, vice president of global powertrain engineering at Ford, said: “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 combustions engines to deliver better fuel efficiency for customers.”
