Don't get me wrong, i do believe that we have to do something to save this planet, no doubt.
But to me it doesn't have that much to do with F1 really, it's still a racing series more than anything else. And the sound of a high revving petrol engine is a big part of what makes F1 what it is, to me anyway.

I have always wondered why diesel engines are banned in F1.
When in doubt, run in circles, scream and shout

Diesel engines are not banned.
http://argent.fia.com/web/fia-public.ns ... 2-2008.pdf
Article 5 of the regulations defines the engines as being:
4 stroke, less than 2400cc, max 19000rpm, as 90° V8s (with the cross section as circular), no supercharging and two inlet and two outlet valves.
Article 19 of the regulations defines the composition of the fuels used.
As no point does it mention how the air-fuel mixture inside the combustion chamber is to be ignited. If you could develop an engine using the Diesel cycle as opposed to the Otto cycle within the regulations, then you'd be perfectly fine.
The question would be whether that would provide any benefit though.The Old Republic was a stupidly run organisation which deserved to be taken over. All Hail Palpatine!

I think section 19 knocks diesel on its head.When in doubt, run in circles, scream and shout

Of course you have to consider the torque and stuff as well, and it's hard to say how much power a N/A 2,4 diesel could put out, but i doubt it would get the 750 or there about of a modern F1 engine. So yes, in my opinion diesels would need preferable treatment to be competive.

98RON petrol contains 39.5MJ/L whereas diesel fuel contains 38.6MJ/L. Theoretically if you could use a Diesel cycle to extract more energy out of the same fuel as a regular Otto cycle then it would make sense.
Since the Diesel cycle uses compression ignition as opposed to spark ignition in an Otto cycle engine, and the real differences are the pressures required inside the engine, I don't think it would that much of a leap to attempt it. Isn't that what you pay engineers to test for you, to push the barriers?
Certainly stopping less in a GP might be worth the effort.The Old Republic was a stupidly run organisation which deserved to be taken over. All Hail Palpatine!

By "diesel" are you referring to the Distillate used in diesel engines or the actual Diesel Cycle engine itself?The Old Republic was a stupidly run organisation which deserved to be taken over. All Hail Palpatine!
