hi all.
has anyone got a picture (or know on the net where there is one)
Of a Formula 1 engine, showing the Fuel injection system

they are interesting in as much as the injectors are suspended
ABOVE the trumpets to the trottle bodies (or they used to be)
Due to high revs i think

just trying to find a pic!

pee vee

thanks mate
managed to find this too
(in a mag, my scanner is foooked so make do with phone pics! lol)


you can see the injectors suspended over the T/B s
(2000 season Ferrari engine)

thanks for that link, i just wanted to see the way they do it again!

Gareth still the bollocks

I must have missed it

GARETH T

alot of race engines has injectors outside of the inlet trumpet

and one of the cossie boys fav inlet manifold does the same

JesseT, just the job mate

What inlet is that Gareth

JesseT

RS500 inlet with 4+4 injectors, with four of the positioned at the end of the trumpets.

thats what i thought but got confused by "outside of the inlet trumpet"

Snowy_Astra

Yeah but on the RS500 inlet the injector heads sit inside the manifold just infront of the trumpets in the plenum. The F1 engines spray through mid air, not in an enclosed environment, straight into the inlet relying only on the engine sucking the fuel in.

Obviously thats cos the RS500 is turbo, and the F1 engine aint, but you see my point

Here's one I took at Autosport this year..

Forgive me for being a bit dumb but is that very accurate? I mean there has got to be a certain ammount of fuel (if only very small ammount) that doesnt get sucked into the engine or gets sprayed and then sucked into the trumpet next to it

Wouldnt it be more accurate to spray it direct into the valve port ???

pee vee

look at that F1 vid.. that shows it!

Keith B

Now thats what I call an injection system! Love the fog of fuel vapour over the inlets in the F1 vid

Snowy_Astra

IIRC spraying it like the F1 engine does as a pose to injecting it into a port (direct port injection) helps the fuel atomise much better, you get an almost perfect mist of air/fuel which pretty much 90% of it gets burt. It all boils down to fitting as much air/fuel into a pot for detonation....it means more power for fuel spent.
