They continued to use cylinder deactivation at low loads for the current era.Powerslide wrote: ↑27 May 2017, 19:48i noticed during qualifying in monaco those rough engine noise are back on lower throttle input. before they were using exhaust to blow diffuser and enhance downforce after double diffuser were banned and now it seems this trick is back. are they deactivating cylinders and those deactivated cylinder used to create power pulses and blow the rear wing or all cylinders are throttled that way instead of typically relying on fuel or air volume control? stratergy around creating more downforce or even maybe some sort of traction improvement?
Blow the turbo, used as kind of antilag. Keep the turbine spinning with cold air from the deactivated cilinder, maybe even hot blowing with the active ones (use a late ignition timing) and it will mix with the cold air from the inactive cilinders.
yes anti lag, they use the anti lag system in formula one even when the cars were naturally aspirated. the thing is, they used it to blow the diffuser instead to produce downforce. could this be the case as well but getting two birds with one dance? blow the turbo and aero element? maybe thats why they got that small wing element around the exhaust exit. what about cylinder deactivation during mild engine loads to improve fuel economy so that they can run the car on lighter load of fuel?NL_Fer wrote: ↑20 Jun 2017, 17:35Blow the turbo, used as kind of antilag.

Monaco doesn't have much good braking points to charge with the mgu-k, maybe they need to save some energy from preventing mgu-h to spool up the turbo.

they actually run the engines hot. well they use to i dont know in this turbo era they still do or not but i dont think they are cooling the cylinders.
