A believable summation in the comments below the psychopath analysis:
Quote:
This seems entirely plausible to me for a couple of reasons. Firstly, you definitely *can* get better power and fuel economy by better atomisation of fuel in a diesel engine, which is why high-pressure, common rail diesels are so much better. Secondly, this is an ancient engine, designed well before the kind of modern techniques that mean current engines only fail to burn a small percentage of fuel. So combine a novel, but crude, technique to better mix fuel and air with immature diesel engine design and you see a nifty improvement.
So whilst it seems plausible, it’s also pretty trivial.
Apply this technology to a modern common-rail diesel engine and i bet you see zero improvement (as you expected).

Or a modern, fuel-injected gasoline engine for that matter.
