It already dates from the end of 2007 but it is a concrete application of the development of new combustion modes:
Excerpt from an article on Motor Nature:
To put it simply, let's write that in everyday use, this engine works like a diesel. The controlled ignition is only used for cold starts, and for high revs, such as above 3500/4000 rpm *. You have to imagine driving a diesel, with the frugality of a diesel, but if you push the accelerator, this diesel turns into petrol, because suddenly the candles start to make sparks, and the engine speed can reach 6000 rpm *!

It uses a variable compression ratio AND a variable distribution.
It's a gasoline engine but we can imagine (if the mechanics support it) "electronically transforming" it into a 100% diesel engine ... in short, does it look like the 1st gasoline AND diesel hybrid engine?
