Oh god, well where to start with you eh chump?!

Not only have you called a number of highly respected people on the forum idiots (or similar), some of which happen to be personally known to me (and I would like to think friends, norbie, thechuckster), but you won't listen to their advice!

Why are you concentrating on the 'can run really lean and can cope with detonation' story? piston deck destruction has very little to do with the mechanics of the conrod - it's to do with the failed combustion event. The piston and/or head metal fails because it's tried to contain an explosion but has failed. Unless the engine uses diesel-engine pistons then it's not going to cope with super-hot lean combustion that regularly detonates.

the reason why convention engine won't be able to contain the detonation is because the weakest link is at the connecting rods where it blows a hole, I'm sure metal can put up with those little explosions

*sigh*....in an engine that has suffered large amounts of detonation it is the TOPS OF THE PISTONS that have holes in them, not the con rods.

Say we use petrol as a fuel, and say it offers 34MJ/litre energy. This equates very roughly to 9.4 KWh per litre of fuel of energy potential. If we have an engine producing, say, 200Kw, then it has to use at least 21.2 litres every hour of fuel.

What's this got to do with a 460cc engine producing 50hp in the early 1920s?? what's the current efficiency of today's engine? Why can't another efficient design that is completely different to the 4-stroke be 2-3 times more efficient?

Umm well it is simple physics mate, the three basic laws are...

*you cannot win
*you can't break even
*you always loose

Wink

Basically you want to get more energy out of the fuel than exists in it....and you wounder why we have trouble grasping how you expect to do this (the current laws of physics still standing Razz

).

Umm if I could be arsed I would check to see what you have listed as your birth date (I suspect it may even be school holidays Razz

)..
