Ford developing cylinder deactivation for 1.0L EcoBoost


Ford delves further into fuel efficiency for the EcoBoost with cylinder deactivation

Ford's award-winning 1.0-liter three-cylinder EcoBoost engine will become even more fuel efficient as the company recently announced that they are developing a new engine management system that will further reduce fuel consumption.

With the application of a new dual mass flywheel, Ford claims that cylinder deactivation on the small three-cylinder is possible. The automaker even stated that cylinder deactivation on the 1.0-liter engine can take place on a wide range of engine loads and speeds while also lessening noise and vibration.

In order to test their theory, Ford recently did an on-road test on a prototype engine fitted with cylinder deactivation which yielded up to 6% of better fuel efficiency. Aside from the unique flywheel, the prototype engine was also equipped with a pendulum absorber and a tuned clutch disc that suited for low revs.


“Even for an aggressively downsized engine such as the 1.0-liter EcoBoost, a significant improvement in vehicle fuel economy could be found by exploiting cylinder deactivation. The highest priority in the development of new combustion engines for automotive applications is the ongoing reduction of fuel consumption,” said Andreas Schamel, Ford Director, Global Powertrain, Research and Advanced Engineering.

There is no exact date yet on when will Ford present a production version of the 1.0-liter EcoBoost engine with cylinder deactivation.
