    Energy can be neither created nor destroyed but can change form.

    So thinking out loud, petrol being the energy, in a limited quantity (100kg) can only be converted into other energy. So in extremely basic terms, rotary energy (power) and heat.
    IF and it is a big IF Renault power units are producing more heat energy, that needs to be dissipated, it must be down on rotary energy(power)?

    I realise that the above is a massive simplification but what do the experts think?

    Basically yes, but it could well be producing the least heat out of the lot of them but just have rubbish cooling systems.
    Heat management is going to be a biggie, especially with every lap using different forms of power in different ways.

    Theres also all the ways that heat has come about, whether its from friction, combustion, electrical etc.
    How is it then leaving the car, whats happening to the intake temperatures, is the engine running lean or rich for what ever reason.

    Massive heat management issues.

    Yes, you can see this in your own car. When the engine on my car reads hotter I notice the fuel shows as lower than when running at a normal temp.

    The other issue is the expansion due to heat and how that could affect the core engine strength and performance. In addition, the higher the fuel tempreature the more it reduces performance, the lower its temperature, the denser it is, so the more power the engine gets when a constant volume of fuel is injected in each cylinder. Each teams cools its fuel therefore to around 10°C.

    Please correct me if I am wrong or anybody can add some additional technical knowledge.

    Some say that the pictures in Haynes manuals are just images from in his head, and that he only drinks high-octane petrol.

    All we know is, he's called Cosicave

    *laughs*

    Is it generating more heat or just not being cooled sufficiently?
