F1 Cylinder Head Design and Pneumatics, a closer look

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

Hi Brian.

This is simply amazing to read... I am a boy on 17 years old, i have dream to become engine builder, i build cylinderheads for old opel cih, the last one i build went out with just above 200 hp, with a sweet camshaft, and small valves, but it was rpming to 9.200 rpm, on 8 valve, i can link up a video from youtube if interested, and send you some pictures if you would like to see my work, now i am holding on for a new cylinderhead with the right valves, and a more aggresive camshaft. For just around 2 weeks ago, the engine i build cylinderhead to was on the dyno against a guy who had build opel cih for 30 years, my engine went out with 208 hp at 8600 rpm and 201 at 9200 rpm, his went out with just around 166 at 6000, and 142 at 7000 rpm!


best regards.

chris

Hello,

I just came across that thread looking for Opel CIH engines, and i ended up reading the whole thread, very interesting, makes me wanna cast a head for my motorcycle...

I wanted to ask you Chrisa, can you post or PM me your engine video ?

Thanks

Ford Uses 3D Printed Sand for Rapid Prototyping

Maker of a dying technology (personal automobiles), Ford Motor Company, has relied on a living technology to maintain its relevancy, releasing this latest promo video on how the car manufacturer uses 3D printing for prototyping purposes.
It’s pretty interesting to see the entire printing to injection moulding process process!

Hi Brian,

I'm Dave Baker of Puma Race Engines specialising in race engine design and cylinder head flow. Maybe at some point in the past you've happened across my old website sadly currently not hosted but it's on the todo list. The Wayback machine archives it here though.

https://web.archive.org/web/20110902010 ... /index.htm

Maybe there's a few things on there that might interest you and give you an idea of what I do.

Thank you so much for posting this analysis. I've longed to see inside an F1 head ever since I started work in this field 25 years ago. This thread is like all my birthdays coming at once.

Hoping you'll still post the valve details and port flow sometime.

regards

Dave

Hi Brian.
Unfortunately I have only just come across your pictures and write up on this subject.
I must say it is highly illuminating and extremely interesting to see this subject in such depth.
I'd like to thank you for your great efforts to post so much information.
Can you tell me if you will be posting more information that you have mentioned?
I realise it must be very time consuming.

Thank you once again, all the best, Geoff

Geoff, Im glad you found it of some interest.

I have a lot of the info already gathered and do intend to post in a few weeks. Currently Im on a contract which involves a lot of travel worldwide so I have to attend to that first.

Regards,

Brian,

hi. sorry for being late, loots of work the last time.

https://www.youtube.com/watch?v=voa2KsVNQlo its a 2,0. with a Enem H12 camshaft. the differential is gone on the video as you can hear, the engine peaks out on 9.000 rpm.

regards chris.

This might be over simplifying, but why not just 3D print the prototype head in Aluminium? No furnace, no sand, no casting, no machining (even internal threads!).

Not sure they fully thought through what 3D printing is...

Has 3D printing in aluminium has improved enough in the areas of porosity, mechanical strength etc that you could print a cylinder head?

1) you can 3D print aluminium with properties well in excess of a casting, if you use the right additive process; especially if you HIP it afterwards
2) it won't be representative of a casting, which is often relevant when prototyping

What would probably be better is to conventionally 3D print the parts with PLA or maybe ABS plastic then do a casting from that as those plastics burns away without leaving residue.
Have a poke around Youtube, there's plenty of videos of people doing it.

(I want to get a Makerbot Z18 printer to do that very thing in fact)

Koenigsegg are 3D printing the stainless steel turbine housings and impellers (concurrently!) for their new ONE:1.
http://www.youtube.com/watch?feature=pl ... NedUZxP8NU

I do understand the high quality nature of 3D printing vs imperfections in cast heads, but the high tolerances in the printed items is what is required for predictable power output and reliability. We are not talking about mass produced items here.

If we look purely at an F1 application, the engine manufacturers only need to make 20 heads (10 sets) per team they supply each year. So 80 heads for Renault and Mercedes and 60 for Ferrari, plus prototypes, so say 90-100 max for each?

Why not 3D print them, it reduces tooling and labour costs and also significantly reduces the time from design to manufacturing/testing?

It does make it difficult to manage and ensure homologation of components...

Another FWIW, SpaceX are printing the rocket engines out of Inconel for their new capsule. It soft-lands under rocket power back to Earth.
