Conceptual engine regulations

All that has to do with the power train, gearbox, clutch, fuels and lubricants, etc. Generally the mechanical side of Formula One.

IL4 driving the front axle and an IL 4 driving the rear - each canted over at 45deg to make a "V8" along the car.

To be serious I think F1 missed a trick not harvesting from the front axle - maybe even deploying too.

F1 can either open the rules to get multiple different configurations like LMH but by limiting power/energy or do as the FIA do now and force a cylinder count/capacity/bore/stroke...etc Regulating F1 so it's at least relatively fair is always tricky.

.... limit boost onset and target its increase to ensure high RPM operation. ....
....anything like a monotonic rise in boost from 0 at x rpm to infeasible at y rpm.....
yes they did that, starting nearly 100 years ago (before turbocharging) ....
driving eg a centrifugal supercharger at some fixed multiple of engine rpm
never winning a real GP though

'they' being famously Duesenberg and Miller and Novi etc - and BRM in Europe
(Tony Bettenhausen's Novi Monza lap record stands for all time)

also millions of such aircraft engines
Good reminder there, you're a trove. The Novi looked remarkably similar to the Merc turbo 1.6 l. In some regards, fwiw.

Eventually the boost level and engine speed correlation gets absurd with f.e. 7,5 bar MAP at 22k RPM.
Absurd? Sounds eminently sensible to me. Should be quite powerful - 4,000 hp or so?

Absurd as in likely infeasible i.e. that which provides the upper limit, not the practical, which would be at a lower value in the specified intake mass flow rate curve yet still by decree high in the rev range of a multicylinder. Painting with prescriptions is the theme of the thread as it relates to the current sport's governing body. If spec bodywork styling, then also spec audio. If so, then do it with some artistry instead of spinning one's wheels in a grovel trap.

Well when you say novel I guess you really mean it--this being an atypical valve arrangement? What else can you tell us about this?

Sorry guys, decided it was too close to off topic so moved it to the interesting stuff thread

I've mentioned this before, but I'll do it again.

Single front electric MU-K only. Torque vectoring differential.

Single rear electric MU-K only. Torque vectoring differential.

Single turbo-jet setup with twin turbo, twin MGU-H.

MGU-H's directly power the MU-K's. In a diagonal fashion, the torque vectoring will be controlled with triggers on the wheel that changes the balance of the power distribution (FR+10%<->LR-10%).

Maybe a 1-2 MJ battery for some hysteresis in the charging system (startup, throttle response).

Powered with EU approved, Green CNG in hot-swappable fuel pods for pit change with tyres.

It's loud, it's fast, it's agile, it has thrust!

Oh, and it's ALL under the drivers direct control with minimal electronics.

That would be entertaining to drive, watch (including pitstops) and engineer...

Maybe. Grosjean might have had an effect on that.

But think of the weight savings. No engine, water, radiators, side pods, anticilleries. We could go back to 500kg with safety!

Creative spin on things there, Zynerji. A turbo assisted pulse jet, I don't think has ever existed (the pulse jet inefficiencies will be pointed out). My take on it would be to replace the combustors on a turbojet with pulse jets. This would be for an aesthetic touch not necessarily a performance gain--again we're in the age of race cars with styling ballast. Although, higher combustion pressures in the combustor might be valuable. It could provide an entertaining sound if tuned properly--most pulsejets I've heard are relatively low Hz. If ganged up in multiples and timed with spark ignition or valve control you could increase the pitch of the pulses to approximate an F1 NA sound. So, one MGUH-turbo-multi-pulsejet (MGUPJ?) driving your axle MGUs.

You need to dump braking MGU energy somehow if you're going to have motor braking, possibly through driving the MGUPJ and porting the MGUPJ compressor outfeed forward for a small reverse thrust. The only cooling you'll need will be for the motors, control electronics, and oil. Relatively small radiators.

Otherwise I'm in support of this as the nemesis EV. The CEV -- combustion electric vehicle.* Mwahaha. All though this is actually the definition of all EVs after the green paint is removed.

In development at dyno stage.
I am retired from the project
Air cooled, showing one advantage of methanol.
Top fuel drag bike application.

Single rotary valve for gas exchange.
For cylinder fill it is like opening the garage door, so in the early stages it only needed 22 psi.(supercharger superceded with turbo)
2.3 litre swept. 10.5 static.
500bhp @ 5000 rpm on the dyno for a 10000rpm engine
Methanol with nitro up the sleeve, twin fuel injectors with a normal return to tank system.
The drawback with a rotary valve is it compromises the chamber shape.
The key to rotary valves is the seal design, this one worked and worked well.
Twin flame ignition which needed only 26 degrees advance, greatly reducing what we call pumping losses.
BSFC numbers are sad which relates to the proposed F1 fuel specs

Zero brake recovery. All carbon/carbon deceleration. 😋

I meant turbo jet... 😬

Just imagine this with current F1 turbos. Especially with VNT for more control.
