Stopping pre burn is the problem they are overcoming they stated, but the common rail high pressure system on petrols would make diesel obsolete they said, giving much higher power figures [up to 250kw from <2.0l and 70mpg +] The high pressure system can inject fuel at up to 4 times per 18deg of crank angle, meaning maximum impact from minimal fuel and air. Apparently Pug have developed it, and will give it to the world to use free, as it will rid cities of unsightly diesel pollution [visible] and cut green house gasses etc. The next 10 years of auto manufacture is going to be interesting....

SNIP I was switched off for a few days after the DID (diesel information day). Was there any discussion here about it? Did everyone enjoy it? Your hypothesis above would be in truer context if DID meant direct injection day. I don't know where the numbers came from, but petrol direct injection has been around since the nineteen fifties. There is a few manufacturers offering it on production vehicles now, both European and Japanese. The example that comes to mind is Audi's 1.6 or 2 litre engine of about 150 horse power. Audi claims a 15% increase in economy. Although I too am a diehard petrol head, that's hardly enough to make one think diesel will become obsolete.

From what was said at DID, they are only needing to get over the pre ignition, or uncontrolled burn issue. DID was Diesel Info Day, and GC and Braggie were doing the report, and took the pics, apart from what you have replied to, not much was discussed on list.

I thought the electric turbos were quite humorous, imagine the "Rice Boys" quoting "10psi boost @ idle!!" Terrific idea though. One important point Dave made was that most of this new technology is driven by emission regulations. If there was no need to reduce emissions we would still be running 2H engines [But think how cheap they would be !!]. Mercedes are currently testing a CRi engine in one of there sedans and are quoting figures upwards of 70mpg. Remember CRi is nothing new as it has been used in several truck engines [Cummins, Cat, Detroit, Volvo yada yada] BUT as I mentioned before if the populous demands lower emission engines the manufacturers will deliver. All we need now is someone to produce a bolt on CRi kit for a 1HD-FT Stephen Mazza
