That's not the right way to put this. Both righier revs and supercharging are ways of putting more air (and thus more fuel) into the combustion chamber over a given period of time. With higher revs you fill and burn more times a second, while with supercharging you just push more mixture in each explosion.WhiteBlue wrote:People who want higher revs first have to invent new combustion and injection technologies.

If you want to go beyond that you probably need 1,000 bar pressure and potentially a new kind of injector nozzle that isn't invented yet.

So all this talk of revs is just not leading anywhere unless someone comes up with a faster injection and combustion system.
Yeah, right. I live in the suburbs here in Sao Paulo and the last gas pump is to be closed tomorrow since we are all runing on fuel cels or solar pannels now.autogyro wrote:All it means is that the motor heads have forced F1 to go backwards twenty years.
F1 will now become a 'historic' formula with a very limited shelf life.
Petrol companies are constantly doing this now and for the last 23 years I've been following F1. Shell for example made lighter fuel for Ferrari a few years back and special engine oil for their ceramic lined cylinders on the V10.andrew wrote:I see what you are meaning but I think JET is hinting at fuel companies looking to get a bigger bang out of less fuel.Dragonfly wrote:Are you serious or just trying to have the last word?

Maybe a seperate topic to discuss fuel mixtures and the possibilities for the new engine format or would this be going into the realms of fantasy and too much speculative conjecture?
And engine maps are so strictly restricted already?Muulka wrote:Personally I think that the best way to go would be to have no boost or rev limit, but seriously restrict the amount of fuel available. How tense would the ends of races be, with people running out of fuel?
I'm actually quite excited by this new formula!
I wonder if strict engine rules really control expense and if so, by how much. With all the "easy" routes to more power/efficiency ruled out, the technicians must explore all sorts of "tiny" ways to eke out a gain -- fuel and oil formulae, materials research, and much more. That must be quite expensive, too.ringo wrote:And engine maps are so strictly restricted already?Muulka wrote:Personally I think that the best way to go would be to have no boost or rev limit, but seriously restrict the amount of fuel available.

I wont hold my breath for the freedom that some dream of.
There will be strict engine rules, as that is the only way to control expense.
V6 midbank single or double side turbo. That's as free as it's going to be.
That is so obviously wrong that you can easily formulate the answer by yourself. You will not increase the power of an engine that is restricted to 65% of current fuel supply by putting more air into it. The engines will not be air rstricted as the old V8s are. The fuel is the restriction. It means that every single hp gained has to come from burning the fuel with higher efficiency. The 2013 I4 was planned with very efficient direct injection and spray guided combustion in mind. Any deviation from that development path will drop power instead of increasing it. I will say it again:rjsa wrote:That's not the right way to put this.

REV LIMITS ARE TECHNICALLY MEANINGLESS WITH SEVERELY RESTRICTED FUEL FLOW UNLESS YOU COME UP WITH TOTALLY NEW TECHNOLOGY.
