New 1.0-litre three-cylinder engine can run on two cylinders; Ford plans to include the tech on next-gen Ecoboost units

Ford has unveiled a lightweight concept version of its 1.0-litre Ecoboost engine at the Detroit motor show.

In addition to the concept, Ford has also confirmed that it is investigating cylinder deactivation technology for the 1.0-litre engine, allowing it to run on two cylinders.

The lightweight Ecoboost concept has been in development for a year. Five of its major components have been changed, resulting in an overall weight reduction of 15.5% versus the standard Ecoboost engine.

The block, cylinder head, connecting rods, front cover and oil pan are all revised on the conceptin order to help achieve the weight reduction. The block weighs 40% less, at 14kg, thanks to new materials, structure and assembly techniques, the cylinder head is half made from carbonfibre, the connecting rods are made from forged aluminium and carbonfibre is used for the front cover and oil pan, which improves NVH as well as saving weight.

Ford is also investigating cylinder activation technology on the engine, which would shut down the middle cylinder.

Andreas Schamel, director of powertrain research and advanced engineering, said an engine smaller than three cylinders would have too many compromises, but shutting down one cylinder in a three-cylinder engine would improve the economy and fun-to-drive characteristics without any trade off.

before we get 3D printed engines which actually arent there at all, just have to use brain power :-)

Pity Ford can't make the whole car 15% lighter and cylinder de-activation seems a little bit unnecessary when there are only 3 cylinders to start with. But good to see that there is still plenty of development potential left in the good old I/c engine.

Yields good results, VW have been doing this for quite some time with 4 cylinder engines shutting down to 2. Get improvements of upto 20%

 

Hydrogen cars just went POP

Surely it's not just the fact that a few kg have been saved, as this could also be achieved in the body, trim & drivetrain. It's more about the reduction in reciprocating masses. Flinging big lumps of steel about consumes energy, and needs large, friction inducing bearings. NVH should benefit too.

Dumping cast iron as the material for the block must save a bit. One wonders if this is part of the development of the Dragon engine. Ford's hybrid future starts now?
