Does someone know if the mercedes benz rotary valve is allowed ? they where going to introduce it and FIA banned it some years ago..

25th October 2012, 17:00 at 5:00 pm #213799joac21ParticipantNo. what is rotary is the valve. cant remember exactly where i read about them but the valve itself doesnt go up and down like conventional ones.. this valves have the shape of a drill and they sit above the head so the flow goes thru the “drill” when it rotates allowing it to go into the chamber and then when they keep rotating they allow the flow to go out…. (i hope this is clear enough haha)…Mercedes Benz was about to introduce them in F1 and the FIA banned them thru the ferrari “veto” of the rules…

25th October 2012, 17:35 at 5:35 pm #213803joac21ParticipantRaymond: Rotary engine and rotary valve are two completely different things,.. rotary engines ARE not allowed. my question was about rotary valves..
25th October 2012, 18:01 at 6:01 pm #213804raymondu999ParticipantAck. Ok didn’t realise that.

Apparently the major issue with the new turbo engines was packaging all the extra cooling required for the larger KERS packs and the extra cooling for the turbo.

The engines themselves will look identical to the naked eye, only the intake/exhaust ducting and as mentioned above the cooling system may have obvious differences, don’t expect anything radical or even interesting.
