Title: F1 piston and Rod
Post by: TTC on March 14, 2010, 07:31:36 PM
I thought it was interesting how short the stroke is, the deck on the piston and how close the valves are actually coming to the face of the piston.

The piston looks similar to a two smoke piston.

The big end of that rod looks like it took some abuse, there's some wear marks in it.

That is why F1 motors consume a quart oil every 15 minutes!

I know the stroke is short cause it revs to 18k, just didnt think it would be that short.

Two rings = more friction = less power?  More weight too.  It's clear that at those speeds and acceleration every gram is huge.

as apposed to the std 3 ring package?

The piston top is awesome. Goes to show that a huge dome isn't ideal.

No, I wasn't considering the oil control setup.  Just "compression."

Flat valve angle is where it's at. 

I like that they use studs for the big end  :yes:

I'm curious about the pin in the center of the big end.  Is that there so if you hammer a bearing it won't spin leading to a mangled crank?

Two rings = more friction = less power? 

i assumed the exact opposite

Title: Re: F1 piston and Rod
Post by: SgtB on March 15, 2010, 09:39:39 PM
Blow-by  = less power.
Title: Re: F1 piston and Rod
Post by: d112crzy on March 15, 2010, 09:50:20 PM
Depends how/why the compression is getting past the rings. There are several ways and most can be solved with a good evac system.
Title: Re: F1 piston and Rod
Post by: 98vtec on March 15, 2010, 09:50:39 PM
Blow-by  = less power.

vacuum pumps + low tension rings = less blow by

this is F1, not cindy's grocery getter.  If the engine lasts for the whole race, they are happy.
Title: Re: F1 piston and Rod
Post by: SgtB on March 15, 2010, 10:06:10 PM
No doubt. i was referring to "why two rings".
Title: Re: F1 piston and Rod
Post by: onlyflash944 on March 15, 2010, 10:51:26 PM
Blow-by  = less power.

what do you think the p2w tolerances are?  I'm betting blowby isnt a big issue

my assumption: one less ring = less friction = more power
Title: Re: F1 piston and Rod
Post by: rsmith2786 on March 15, 2010, 11:46:42 PM
Also just think of the insane velocity.  There isn't even time for significant blowby.  You could run no rings and i bet it would stilll run without much issue.

actually i think the engines have to last 2 races now

No three races, they get 8 engines for 19 races, practices, and qualifying.

Some are using one engine for practices and the rest for qualifying.

The post picts. looks like the older rods and piston configurations. I remember seeing the rods look more intricate and the pistons even lighter before.

Watching the top gear episode where richard hammand(spell) drove the F1 car, they said the engine is almost locked up when cold so they run warm water through it to heat it up, same goes for the oil. I would then say the clearances are tight.

yeah same with some of the high dollar exotics, you can start it cold but it has to idle for like 20 min before you can drive it.

Most people will comment on the piston only having two rings.

on my 450R MXbike i run a cp piston with only one compression ring and oil control rings. it is because if produces less friction, and revs quicker. i noticed a difference between the 3 ring i ran before compared to the new 2 ring.

with the one less ring, i didnt notice any more blowby, but the ring end gap was absolutely crucial, as i was told by the company that did my head work. also the service intervals are alot more frequent than the 3 ringers.
