If you read it all, it mentions that it can achieve the MPG of a diesel engine without such harmfull toxins etc produced by diesel engines, i.e best of both worlds.

The exhaust gases from a 4-stroke have a certain amount of energy. This seems to be attempting to use that currently wasted energy to drive another piston (and presumably then exit the engine cooler than currently).

Yes looks like the high pressure from cylinders 1&3 are used to drive cylinder 2 (low pressure)

I assume its sort of catching the last bit of energy from the engine, or something like that, its interesting how the cams rotate at different speeds, it would be nice to see a CGI of one in motion. They mention they had a cut away one you could turn by hand, i would like to see that at Autosport or something.

I love this 'out the box' thinking, like the (canadian??) guy who built the engine that had extra cylinders in the head that worked like valves.
