A shameless image thread for the enginephiles

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

I have discovered that instead of counting sheep before sleep, trying to imagine the spatial movemet of pistons in a Napier Deltic engine is much more effective :)

And I have spent hours exploring the cutout drawing of the Napier Sabre which appears to have sleeve valves (not sure this is the right English term) and an explosive charge starter along with the rest of units.

One of my creations. Ferrari F106A block from an early 308 modded to no end, lots of revs and lots of titanium. Sounds like a detuned DFV engine.

Yes, Sleeve Valve is the correct term in English. And, yes, the Sabre has them.

The "explosive charger starter", known as the Coffman starter, was not uncommon for WW2 era piston aero engines. Certianly the Merlins in the Spitfire had Coffman starters - at least in the early variants.

FWIW:

R-4360 - 4360ci = 71.45l, 3500hp - 3800hp (best versions), 3800lb = 1724kg mass.

Sabre VII - 2240ci = 36.7l, 3500hp, 2600lb 1179kg mass.

These power levels were for takeoff, had short time limits (~5 minutes) and required ADI (water/methanol injection).

Sabre's mass doesn't include water cooling system (radiators, tanks, etc), but that would take the total up to 3000-3200lb (1361-1451kg).

Best thread in the forum.
Makes me wish F1 would adopt the weird philosophy that HP is an important part of racing and that increasing HP is not taboo.
I'll post some US engines if I ever figure out how to do it.

the only 'real' multi-bank engine to become established seems to be the non-aviation Russian JSC 'Zvezda' diesel turbo-compound
this has 7 banks of 6 cylinders, or now 7 banks of 8 cylinders (currently giving 5200 hp @ 2200 rpm and costing about $220000)

@ wuzak
Cofmann starters were in widespead use in short range UK airliners till the early 60s (Hercules and Centaurus engines)
I think I remember SAS? Convairs using them also ? (on their P&W engines)
(this was presumably due to poor ground facilities for mass bettery charging)
there was an explosion of black smoke and noise that must have seemed remarkable to passengers
Merlins only had Cofmanns for carrier use (and high altitude versions, electric starters being removed to fit pressurisation pumps)

Very nice, an xpensive gamble that paid of for Mercedes. I recall watching this live with my dad in Namibia, who was a massive Emmerson Fittipaldi fan.

Someone posted a pic of the Subaru flat 12.... Well here's one another, Mercedes C291 prototype M-291 fat 12 beauty.

Credit an old friend for sourcing much of the photos(747heavy), whom also added some interesting bit an bobs about the engine and it's history.
747heavy wrote:Mercedes also designed a flat 180-degree 12-cylinder engine, the M291, for use in their C291 Group C car. This engine gave Michael Schumacher and Karl Wendlinger victory at Autopolis in the Sportscar World Championship season finale. Earlier this engine was plagued by oil-scavenging problems but they were solved and the engine was ultimately reliable enough to win but still hefty at 170kg.
And here is what it sounded like.

Smokey Yunik School Bus Engine.

Literally pulled this engine from a school bus then qualified it for Indy back when that meant something.
