The 1.0-liter EcoBoost has only three cylinders to begin with, but Ford can make it run with just two to boost efficiency.

Ford’s engineers are doing their best to cut fuel consumption and CO2 emissions as much as possible and that’s why the small turbocharged 1.0-liter three-cylinder unit part of the EcoBoost family will receive cylinder deactivation technology. It will happen at the beginning of 2018 and the Blue Oval company is proud to announce it will be the first automaker in the world to offer this sort of tech on a three-cylinder unit.

When the engine’s full capacity won’t be necessary, like when coasting or cruising with very little demand on the engine, the first cylinder will be automatically deactivated to increase efficiency by as much as six percent. It’s going to do that by stopping fuel delivery and valve operation in as little as 14 milliseconds, or 20 times quicker than the blink of an eye. Ford promises the driver won’t notice at all the switch from three to just two cylinders and vice versa, which will take just about the same amount of time to fire up that third cylinder when the engine’s full capacity will become necessary once again.

Available at engine speeds of up to 4,500 rpm, cylinder deactivation for the three-pot turbocharged unit represents the joint effort of Ford’s engineers based in three countries: Germany, U.K., and United States. They worked together with Schaeffler Group to perfect the technology, which required the development of new software capable of detecting when it’s the right time to turn off/on the cylinder.

To increase the 1.0-liter EcoBoost’s refinement especially when running on just two cylinders, Ford has developed new engine mounts, drive shafts, suspension bushes, as well as a dual-mass flywheel and a vibration-damping clutch disc. In addition, a revamped camshaft chain and valve rockers were necessary to increase the unit’s durability.

Launched back in 2012 on the Focus, the three-cylinder mill is currently available in three outputs: 100, 125, and 140 hp. No less than eleven models sold in Europe are available with the 1.0-liter EcoBoost, including the new Fiesta introduced yesterday.
