Auto Trivia

[Woodsie888]

What everyone given up on the first 4 door Porsche?

You mean a regular production car with a Porsche name or the RS2?

Regular production car, designed an built by Porsche

I give up, unless it was a post war military car.

Cayenne?

So...what about the first DIFFERENTIAL?

First diff. in a car? Difficult! It is such an old invention. I remember on the History Channel a south pointing cart in China way back when but don't think they actually invented the diff. Its one of those things one discovers when playing with gears or trying to push a Kart around in the pits!

First diffs were found in China - one or 2 thousand years back.....I was pointing out that most mechanical automotive parts we're around for centuries before coming together in the automobile.

Here's a potted history from wiki.

Basically the diff preceded the internal combustion engine on road-going vehicles.

• 1050 BC–771 BC: The Book of Song (which itself was written between 502 and 557 A.D.) makes the assertion that the South Pointing Chariot, which may have used a differential gear, was invented during the Western Zhou Dynasty in China.^{[citation needed]}
• 150 - 100 BC: The Antikythera mechanism has been dated to this period. It was discovered in 1902 on a shipwreck by sponge divers, and modern research suggests that it was designed to predict solar eclipses using differential gears.^[3]
• 30 BC - 20 BC: Differential gear systems possibly used in China

South Pointing Chariot model

• 227–239 AD: Despite doubts from fellow ministers at court, Ma Jun from the Kingdom of Wei in China invents the first historically verifiable South Pointing Chariot, which provided cardinal direction as a non-magnetic, mechanized compass. Some such chariots may have used differential gears.
• 658, 666 AD: two Chinese Buddhist monks and engineers create South Pointing Chariots for Emperor Tenji of Japan.
• 1027, 1107 AD: Documented Chinese reproductions of the South Pointing Chariot by Yan Su and then Wu Deren, which described in detail the mechanical functions and gear ratios of the device much more so than earlier Chinese records.
• 1720: Joseph Williamson uses a differential gear in a clock.
• 1810: Rudolph Ackermann of Germany invents a four-wheel steering system for carriages, which some later writers mistakenly report as a differential.
• 1827: modern automotive differential patented by watchmaker Onésiphore Pecqueur (1792–1852) of the Conservatoire des Arts et Métiers in France for use on a steam cart. (Sources: Britannica Online and^[4])
• 1832: Richard Roberts of England patents 'gear of compensation', a differential for road locomotives.
• 1874: Aveling and Porter of Rochester, Kent list a crane locomotive in their catalogue fitted with their patent differential gear on the rear axle.^[5]
• 1876: James Starley of Coventry invents chain-drive differential for use on bicycles; invention later used on automobiles by Karl Benz.
• 1897: first use of differential on an Australian steam car by David Shearer.
• 1958: Vernon Gleasman patents the Torsen dual-drive differential, a type of limited slip differential that relies solely on the action of gearing instead of a combination of clutches and gears.

Dr Porsche - stole the concept for the VW from Tatra before WW@. After the war Tatra received a paltry compensation for this - but Ledwinker, the real designer has never received full credit for the vehicle.

VW 411...............

[VocalNeal]

Neal .As in Ferdinand Porsche or the Company.

Built by the Porsche company.

VW 411...............

It is not something I would have known I just stumbled onto it. Someone will have to Google.

[transam]

What is/was the biggest (CC's) transverse (sideways) engine in a production car ?

Forget this one cos I got it wrong too........... .............

[transam]

Will try again, what is the biggest engine (CC's) put in a front wheel drive production car ?.

[Jitar]

Biggest transverse engine in a production car - Cizeta 6L V16 (if ~100 cars counts as "production")

Biggest engine in Front wheel drive production car - Mid 70's Cadillac Eldorado 500 cu in / 8.2L

7,456 cc.

[transam]

The real Mini , the basic cc 850 and 997,998,970,1071 and 1275 Coopers were basically all the same except performance and engineering differences but the 1275 had one thing different to the others, what was it. ?

[Crossy]

Right hand (2nd) fuel tank? Oil cooler?

My uncle Phil had one with machine guns (OK they were long grille nuts that he turned up at work from aircraft grade aluminium).

larger capacity motor.

hehe

[Ace of Pop]

425 cc extra, as Woodsie said, and a different grill or oven.

[transam]

I think I have got you all with this one............ ......................

Higher tire pressure ?

Drat, been found out.........

But nooooooo...........Try again...........

1275 Cooper S had an 11 stud head

So did the other Cooper S, sooooooo no.......... ............

[VocalNeal]

Seeing as y'all gave up on the hard one?

1952 type 542

Designed and built by Porsche sold by Studebaker

[VocalNeal]

So did the other Cooper S, sooooooo no.......... ............

I had a black one so I'm thinking.

Twin tanks?

I guess well go through them one by one.

[Ace of Pop]

Got yer now T.A.. it was offered in Turquoise Blue as a Factory Colour.

[transam]

Suppose I must tell you .

All the Mini's including the Coopers had 3.75 final drives except the 1275, it was 3.4. .......

(I think)..... , well I am doing this stuff from memory.

[Kwasaki]

And there's me thinking double overhead cams and 4 valves per cylinder.

In the interests of accuracy, I think you mean 3.44.

Memory at your age ?

Come on Trans, I'm sure you even don't remember your last post

[Ace of Pop]

Yeah, hes even overlooked my Colour answer. That Model was the only S to have it,

What about your Key Gas..... ...............

[transam]

On a car truck or heavy goods vehicle, how many types of braking systems can you quote. By that I mean as you put your foot on the pedal, between the pedal and the shoes or pads. .

OK then 4.5 inch rims.
