cracking video thanks for posting,its amazing what martin brundel said on comentry of f1 at weekend,modern f1 engine produce loads of compression what a load of crap they dont produce and cannot produce any more than the dfv of the 60's.

It is amazing how you can see the fuel going in but my video is stalling out a little.

Here is toyotas engine / hopefully the link works.

Doah doesn't work . . . try this . . . and Toyota should be the first one to click on

i would imagine they're not exactly low compression though....

That's not the fuel going in! Even more amazing it's water vapour being formed due to the low pressure created at the intake tumpets!! It's the same effect you see on the top surface of aircraft wings on humid days.

13:1 which is the ball park limit,increase the stroke you'll get it higher at a cost of rpm then the power goes down and we dont want that in a f1 motor,with 90+ mm bore area 17mm valve lift there's no time for making big compressions,in fact theres not much time for the four cycles to do there bit.

thats intresting, i was guessing the would be running some 20:1 + cr's. thanks for clearing that up

20:1 is totally out of the question,they are like diesel engines in combution area-there is no combustion chamber so to speak this is the only way the guys can get the compression up.

Leave compression ratio’s alone for a second, remember that the engines on Formula 1 cars experience more than 100% cylinder filling due to the effects of dynamic pressure so BMEP of the air alone is probably equal to Atmospheric pressure * Dynamic pressure * Compression ratio. Although the compression ratio is probably approximately the same as a highly tuned road car the actual pressure in the cylinder is much higher. The choice of fuel probably reflects this, as I understand it’s carefully engineered to allow high cylinder pressures (although it is claimed it is pump fuel).
