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.

Flat 12, actually. From the 4wd '47 Porsche Cisitalia 360. That 'exhaust pipe on the diff' should be for a starter motor shaft.

Interesting history:

In November 1945, Porsche was asked to continue the design of the Volkswagen in France and to move the factory equipment there as part of war reparations. Differences within the French government and objections from the French automotive industry put a halt to this project before it had even begun. On 15 December 1945, French authorities arrested Porsche, Anton Piëch, and Ferry Porsche as war criminals. While Ferry was freed after 6 months, Ferdinand and Anton were imprisoned first in Baden-Baden and then in Paris and Dijon.[27]

While his father was in captivity, Ferry tried to keep the company in business, and they also repaired cars, water pumps, and winches. A contract with Piero Dusio was completed for a Grand Prix motor racing car, the Type 360 Cisitalia. The innovative 4WD design never raced, but the money it received was used to redeem Ferdinand Porsche from prison.

The company also started work on a new design, the Porsche 356, the first car to carry the Porsche brand name. The company then was located in Gmünd in Carinthia, where they had relocated from Stuttgart to avoid Allied bombing. The company started manufacturing the Porsche 356 in an old saw mill in Gmünd. They made only 49 cars, which were built entirely by hand.

That's a cruel way to describe a Porsche RS Spyder. :lol:

Wow. Flat-10. Mechanical fuel injection. Supercharged? Exhaust pipe on the diff? Weighs as much as a "Honda!". What is it???

PS, Love the DHL box as HVAC nfix in the background. Good to know Porsche stoops to my level sometimes.


PPS, Is that a 'birdcage' Maserati just peaking out on the right?
It's actually a flat 12 :wink: had a sequential shift 5 speed, dual super chargers. Made just shy of 400hp. It was developed for F1 racing by Porche himself but didn't race due to the war.

edit: Ahhh roon beat me to it! To add to his post, the 4WD was selectable by a lever in the cockpit. It could be used for traction out of slow corners or in wet races but could be reverted to RWD for efficiency gains.

I forgot about the Crysler, roon. https://en.wikipedia.org/wiki/Chrysler_Patriot

It says they had issues with the flywheel working. Didn't Williams develop one years ago?

What's the piston engine? Looks like a dual sharing the same journal but offset rod locations.

Single-cylinder stationary engine. Home power generator. Honda. The extra pivot attaches to a second conrod and a secondary crankshaft spinning at half crankshaft speed. This alters the stroke of the piston every half four-stroke cycle (360*). The expansion stroke is longer than the compression stroke. In effect: Atkinson cycle, but not through valve timing

Roon I was wondering..Is that an outboard?
I agree it looks like some kinda Evinrude or Mercury.
