In their 1.0L 3-cylinder turbo Ecoboost engine, that is.

http://www.greencarcongress.com/2016/11/20161130-cylinder.html

Significant modifications were required to get a 6% fuel economy improvement:

Quote:
Ford’s single-cylinder deactivation design reduces complexity to make volume production achievable, but also presented significant challenges in maintaining the 1.0-liter EcoBoost engine’s acclaimed refinement—delivered using innovations including an offset crankshaft configuration and deliberately “unbalanced” flywheel and pulley that counteract vibration.

A new dual-mass flywheel and a vibration-damping clutch disc help neutralize engine oscillations when running on two cylinders, especially at lower rpm, and enable a wider operating range. Intake and exhaust valves are closed when the system is active, trapping gasses to provide a spring effect that helps balance forces across the three cylinders for refinement, and also retain temperatures inside the cylinder that maintain fuel efficiency when reactivated.

New engine mounts, drive shafts and suspension bushes also will be specially tuned for refinement. The 1.0-liter EcoBoost will feature enhanced durability to cope with the different loading forces resulting from cylinder deactivation, including a new camshaft chain, and valve rockers formed using advanced metal injection moulding.


Will the 3.5L Ecoboost V6 be next in line for this tech?

I see the AFM or "cylinder de-activation," or the Displacement-on-Demand system as a carbon/soot maker.

For this system, why not just have one big honkin' cylinder moving fore and aft, like on the old steam locomotives. grin2

GM sells over 40,000 half-ton trucks with this technology (cyl.deactivation) each and every month. While there were some issues early on (2007) most issues have been resolved.

If you research GM's system-you will find it's a fairly straight forward technology. It's already on 4.6 million cars/trucks.

The new generation 2.0 Ecoboost already has this. So I was told when I bought mine this past Saturday. Maybe for 2017 models.

LOL, i was thinking the same. cylinder deactivation in 3-cylinder engine. really?

how about 2 cylinders, start/stop system, and more boost?

or better a hybrid?

My 2013 JGC with the 5.7L Hemi has cylinder deaction. It's on/off action becomes annoying so I move it out of Drive and choose one of its 6 speeds, eliminating the constant(sometimes) on/off action.

Yes, the cylinder deaction saves some gas but not much according to my records.

The cylinder shutoff in my Magnum was 100% transparent...to the point I asked the dealer to make sure it was working! (It was.)

Where have you been for the last 10 years - GM, Chrysler and Honda brought it back from the dead. Modern PCMs are much faster, being based on 32-bit PowerPC(what Apple was using before the Intel switch) or MIPS/Super H processors, while the Delco ECM that drove the 1st gen V8-6-4 system was no more powerful than a TI or HP business calculator at the time.

I can commend Ford on wanting to do this - but I think we're hitting the law of diminishing returns. Ford's probably eyeing this to go behind a PHEV powertrain, not quite GM's Voltec...
