Sounds interesting. Why's it going to go wrong?

Do you have any more info on this or how it works?

The blurb on the page for the current skyactiv engines discusses how they manage to get the current high compression ratio by removing "residual gas" and thus reducing the temperature in the cylinder.

And there's a page for the diesels as well that mentions opening the exhaust valves on the inlet stroke to increase temperatures on warm up, which allows them to use a lower compression on a diesel engine. Which is an interesting reversal.
