F1 engine project

[Stevie]

Hi engine fans
Well it's time for me to make something other than a cnc machine
I have decided on my real passion (watching F1 since i was 15)
So a scaled down version of a V10 is what I plan to make

]

Some lines are just for construction
But the basic crank/rods I feel is close to what might work for this
The crank will be cut away for counterbalance but at this point thats work I just don't need to do
The banks are 201mm long; with bore centers at 38.44mm
Bore/stoke are 32.43mm by 27.14mmfor a total displacement of 224.178cc or 13.68 CID

Can't wait to see this.

Awesome! Can we expect 24,000+ RPM, pneumatically operated valves (4-5 per cylinder), direct fuel injection, magnesium alloy block with the theoretically ideal 72 degree V-angle (dry sumped, naturally) etc? Also, are you going with the inconel exhaust within the V (Ferrari style)?
Crazy F1 designers/engineers!
Seriously, it’s an ambitious (but really cool) project. I wish you luck, and I hope you keep us updated here of your progress.

[ger21]

Is this designed from scratch, or are you copying something?

[Stevie]

I emailed Cosworth and Judd
No luck
I'll be designer/engineer etc

as for Valve train; I'll try pneumaticallyclosed; might not be possible; they will be small
4 Valves per cylinder; actually the block is 90dgr; 72 dgr got way to tight; the throws are 72dgr
Rods will be I beamed; I'll just re-draw 1 for machining

This is a pretty cool project.

What is your estimation of the number of hours it will take to complete this project? I expect it will be a long term project even if machining is performed on a CNC machine.

Just curious,
Jerry

Ok I'll throw a few of my ideas in here; I'm open to comments etc with this; it is a big project; I feel not outside whats possible; my machines can do most of it; the gantry is just about to run; the mini mill can do a lot of neat stuff; if a new machine is needed for say grinding the cams; well i guess I'll just have to build one

So Ideas
I'll run it on Methanol with some nitro 10% maybe more "why" well making a tiny spark ignition system seems out of the question; unless someone here can help
The Cams I'll drive with XL timing belts!!
Crank; 4340 or 4140 pre-hard? I'll center drill 6 times per end; this will allow me to turn/grind the throws first; then turn/grind the journals; last would be the timing and flywheel ends; which would remove the 5 centers needed for the throws

Yes dry-sumped
Water cooled; the block might be laminated from 1" thick plates; this will allow me to create the water jackets;I really don't want to be casting parts; heads will be the same laminations; there can be Vitron O-rings to seal the laminations
Head bolts will go all the way to the crankcase webs for max strength

Any ideas out there?

Hi Jerry; about a year might be more

Should be a fun project! I think getting the fuel injection and pneumatic valve train working at this size will be really tricky. I am not sure you would even need to go to pneumatic valves given the massively reduced valve train weight compared to an original F1 engine. There is a book available that gives a very detailed breakdown of a modern Ferrari F1 engine, just can't remember the name of the top of my head. Have you seen it?

Also there is this Aurora IRL engine replica

Here are some good references for general model engine building

Spark ignition is certainly possible at this size. You can pick up components for a hall effect system pretty readily and also miniture spark plugs.

There is a guy at the Toronto model engineering club who has built some engines with solenoid operated valves. They are pretty cool. He has then operating up to about 15,0000rpm at the moment.

[Stevie]

Nope; have not seen it; good link you posted; never knew about them; they are quite close to me; close to Ger21 for sure he lives in Michigan; just over the bridge from me

[pstockley]

Forgot to mention, I know a guy in the club building a 1/4 scale V8 and he is using minature roller chain for driving the cams. This would be an alternative to using a timing belt.

I always thought that a 1/4 scale cosworth DFV would be a neat project. Maybe someday!
