In collaboration with engineering partners Schaeffler Group, Ford has been evaluating cylinder deactivation on its three-cylinder 1.0 litre EcoBoost engine in a bid to make the award-winning mill even more fuel efficient.
On-road tests using a working prototype have showed fuel efficiency improvements of up to 6% after engineers conducted an experimental investigation into cylinder deactivation. The evaluation has also seen the development of a new dual mass flywheel, which has enabled cylinder deactivation to take place at a wider range of engine loads and speeds.
For the trials, engineers equipped a Ford Focus 1.0L EcoBoost with cylinder deactivation hardware that they could monitor deactivation of one cylinder. They also explored rolling cylinder deactivation to run the engine in half-engine mode.
They also fitted the prototype with a newly-developed system that combined a dual mass flywheel, a pendulum absorber and a tuned clutch disc, which the automaker says is particularly effective at lower revs. As well as enabling a wider operating range of cylinder deactivation, the system helped counteract any effect that the cylinder deactivation had on levels of noise, vibration and harshness.
Fuel efficiency improvements were recorded in homologated conditions and during test drives of the prototype vehicle, done over a typical commuter distance of 55 km on a combination of motorway, city roads and rural roads in and around Cologne, Germany.
Cylinder deactivation is among a number of fuel efficiency solutions Ford is investigating for its three-time Engine of the Year winner at its European Research and Innovation Centre in Aachen. In Malaysia, the engine is currently available on the Ford Fiesta 1.0L EcoBoost.

Hmmm…this tiny mill is getting more complicated.
Campro still the world’s best engine.
Hehe..u can talk whatever u want because of your “kiasu”ness..just wait and c 2-3 years coming this tech will b available in Proton TGDI engine..Hahaha..
Syiok sendiri never stops. Sigh…
Easy own. Harder to sell. Hahaha
Yah, world’s best engine in ‘eating’ oil
Not really, more powerful than 2.0l VTEC
are u kidding me??use campro compare vtech ???? campro just nothing ,just a the 1st twin cam 16 valve engine in proton history
cylinder deactivation is definitely a welcome addition especially for those who spent most of their time in traffic jams
It’s either that or engine start-stop. And who wants their aircond compressor to stop during a traffic jam?!
start-stop if not implemented properly can be very annoying & on some cars it won’t work if it thinks the car is using too much power.
Not sure weather complexity is the way to go for something that is, in all intends and purposes, a very complex mil. The small, and I mean something with 1.0l small, usually do not live out to their expected Fuel Consumption figures in real world driving. Also reliability becomes an issue if, like my family, holds on to a vehicle for more than 10 years.
My concerns exactly. It’s already a pretty highly stressed engine and now they’re adding even more things that could go wrong. I hope they carry out a thorough durability test on this thing.
To put it into perspective, this diminutive engine produces the same power per liter as the 8.0-liter 16-cylinder Bugatti Veyron. But it costs a fraction of that Veyron stupid car!!
So if your 5 litre TNH or BMW has less than 125 HP per litre, your car is definitely underpower and its time to change. Do not attempt to race against it from stand still.
Engine of the year, 3 times over. Great stuff!!
Another keyboard warrior looking up spec sheets.
Who cares about specific outputs. I figured that by now the guys have learnt that although your car may have super high specific outputs, you’d still get spanked by Turbo and Big displacement engines. Its torque that matter.
The point is, even if you make 125hp/L, you still only HAVE 125hp. A 328 which only makes 120hp/L will still run rings around the Fiesta…let alone a Veyron.
Lets see how you manage to put a super high specific output superbike engine in a car and see how you fair…….
Well said, but I think that Bobby guy might have been sarcastic. For his own good, I hope he was.
WOW! cylinder deactivation on a 3-cylinder engine? Means only 2-cylinders running. I really wonder how’s feel like running on 2-cylinders.
Possibly,
1. Deactivating the centre cylinder leaves 2 cylinders running, 1 & 3 = very well balanced engine.
2. Going extreme by deactivating 2 cylinders, 1 & 3 = only the centre cylinder 2 running + slight overboost to maintain rotational inertia. Perfectly balanced engine.
Either way, it’s an amazing engine!
2 cylinders. Lol, like the Alfa Romeo twin air engine. XD
