Silver cables heat up pretty easily. So I dont think it woul be smart to use it.langwadt wrote:well, silver is ~5% better but it is ~15 heavier, aluminium is ~twice the resistance of copper but only ~30% of the weight.poz wrote:Are silver cables permitted ?

Another issue is contact resistance between the cable itself and the various connectors/connections at the ends. I think I heard something about U.S. houses going to aluminum wiring during WWII copper scarcity, but having fire problems due to increased contact resistance at the ends of the wiring. There's a lot to think about when you have wires transferring 200 hp of electrical energy in a tiny, light car.nhojekim wrote:Silver cables heat up pretty easily.

The issue with the aluminium wiring was that if it isn't done just right it get lose and corrodesbill shoe wrote:Another issue is contact resistance between the cable itself and the various connectors/connections at the ends.

Jerez Ted's Notebook, day two - AC (RenaultSport). Converters in the ES, which IIRC were a big part of the thermal issue.Mr.G wrote: All the wiring depends on how the MGUs are build.If they have their own AC/DC converters then the link between MGUs and ES will be DC. If they are pure AC the linking will be AC too. I think they are running the first option.
I'm fairly sure all the engine manufacturers are doing this. None of them want to burn fuel they do not have and as well as that turn that fuel into heat in the engine. It is a fairly basic principle so for now it would be safe to assume all the engines do thiseslam1986 wrote:Ferrari engineers are studying a system which allows to cool down the V6 taking advantage of a feature of the engines 2014: direct injection. Basically, when engine power is not required, there is absolutely no fuel and no ignition of the spark plug: air enters only through pressure from the turbo.This lead to a cooling of the piston crown, the cylinder and the combustion chamber without having to use, as they did with V8, a small amount of fuel.
This could be related to the "exotic materials" there was talks about on the closed reveal of the engine.eslam1986 wrote:from Lorenzo De Luca : Ferrari F14 use Ttitanium microtube heat exchanger with two tenths of a millimeter internal diameter used to cool the V6 059/3, capable of ensuring the necessary cooling with much smaller dimensions.

I dont see anything special or innovative in cutting the fuel injection either. To me its just logical to do so. And if they are doing something it could be what i has been talking about for some time which is keeping the throttle bodies open when the driver is off throttle. Eccentially a sort of cold blowing. This would have some advantages which I've written about in other threads.trinidefender wrote:I'm fairly sure all the engine manufacturers are doing this.
