Morris Minor Owners Club

At the risk of ruffling more feathers, I'll be quick. If you wanted one of these by mail, please PM me an address, I'll return mine and on receipt of a cheque (payee details by same return PM) for ten pounds per shirt, send one.

they are very nice indeed!

and the shirts are very nice as well

A small point, but with petrol 4 stroke piston engine, it should strictly be "suck squeeze BURN blow" as the combustion stroke is a fast burn rather than an explosion. If not then you have pinking ;-)

Yes, but Bang is much funnier

Pinking? surely, as a small point you mean pre-ignition

Nice to see Cam made it in the end as well.

Nice photo of the group
How about putting names to faces ??

Well the ones I know, sorry to the others poor memory

dieseling.

Two different things.

dieseling (′dē·zəl·iŋ)
(mechanical engineering) Explosions of mixtures of air and lubricating oil in the compression chambers or in other parts of the air system of a compressor. Continuation of running by a gasoline spark-ignition engine after the ignition is turned off. Also known as run-on.


Knocking (also called pinking or pinging)— colloquially detonation—in internal combustion engines occurs when air/fuel mixture in the cylinder has been ignited by the spark plug and the smooth burning is interrupted by the unburned mixture in the combustion chamber exploding before the flame front can reach it. The engineered combusting process ceases, because of the explosion, before the optimum moment for the four-stroke cycle. The resulting shockwave reverberates in the combustion chamber, creating a characteristic metallic "pinging" sound, and pressures increase catastrophically.

Do I win a prize?

No!! Kevin and I didn't feature, and your spelling of Matt is incorrect

Oops I *think* I have one of you in the shirt at the prize giving - which was much appreciated, btw. I'll dig it out and post it if I have

Which proves my point, it would only be a bang if the engine was not running correctly. Otherwise it should be "suck squeeze burn blow" unless its a diesel engine.

So YOU get some shirts done... The 'humour' relies rather on the fact that it's a pretty common phrase, and disappears rather if you alter it, I'd say. Still, that's me put in my place.

I'm just trying to clear up a common misconception about the internal combustion engine. No offense meant!

Are the t-shirts funny? ;-)

No.

This discussion revolved aound the wording on the T shirt. This wording was based on accepted terminology.

To support this I would bring your attention to Exhibit A - http://www.bbc.co.uk/dna/h2g2/A633232

In view of this I rest my case for the defence

I don't know who invented the mnemonic but I first heard it on a TV programme made in 1991.
