Oh Dear ! What an unfortunate name.....

Todd W

I certainly would not like to be in Todd's shoes (apart from the salary bit).

Now that has to be the wierdest name I've come across recently.

Poor bugger, I bet he's heard 'em all. :-D

[Edit]

Now when you overhear someone saying Win XP SP2 was created by a W**** , you'll know that he's just stating fact and not really cursing at all. :lol:

[x56h34]

Hehehehehe. Nice. :-)

[PMC]

That's pure class.

OMFG, Microsoft has fanboy sites too?! :-o

I bet you all laughed and sniggered at school when you were taught about the Wankel rotary engine..

I don't recall learning about that at my poxy comprehensive. :-)

It might sound a silly name, but I remember it was quite a revolutionary (no pun intended) design...

IIRC it has fewer moving parts overall, better power transmission efficiency etc. The only stumbling block as I remember was the seals on the 'cam' (not sure what the correct term for the rotating doobrey that replaces the piston is). The materials available at the time weren't up to prolonged use, gradually wearing away and causing the thing to break down. Presumably modern materials have solved this.

Doesn't one of the newer Mazda's use a Wankel engine? Except it is now called Rotary. Presumably the marketing people thought "Wankel" was not going to sell.

Wankel engines are thirsty IIRC...

Anyway, I was leafing through my paperwork yesterday morning and was handed a stack of P46 forms (these are sent to the local tax office to advise them when an employer takes on a new member of staff, listing their name, National Insurance number etc).

The company employes a large number of foreign workers, the one that caught my eye though was a gentleman named:

Mr Johnson S#itty

:lol:

The big problem I have with them is thermal efficiency and incomplete combusion, due to the large surface area and weird shape of the combustion chamber. they will never be as efficient or clean as a standard IC engine... but the complexity of a Wankel is so much less that they are often less than half the weight of a normal engine, which balances out that :-)


Personally, I prefer the Quasiturbine :-)

@ Karlos... I think it's called a rotor  :-D

@ Bloodline, the poorer efficiency of the rotary engine is  to do with the compression ratio of the fuel/air mixture which can be achieved.

Also, what's a quasiturbine?  some kind of hybrid gas turbine which is efficient at low revs?

[Karlos]

@Star69

Probably. I said cam because the non-uniform shape (which IIRC is slightly cam like) is designed to compress the combustion mixture as it revolves in the casing.

[Star69]

Just yanking your chain mate :-)

I hate it---I mean, really, really hate it---when people mention their little management philosophies like they have the sun shining out of their butt or something. 'When you look at all those emails, you will hardly ever see the word 'I'. I believe that in a team there is no 'I', everyone has equal say.'

Yeah.

Right.

Next time I am in a team-oriented environment as a lowly junior, I'll mention this. I am quite sure what the response will be.

I still do hehe...

Not it's a bit like a Wankel engine, but it has a 4 sided rotor, the sides of the rotor are not fixed, but hinged.

Due to this the Rotor doesn't need to be offest from the drive shaft, thus it has 0 vibration and is more efficient than a Wankel, though it has similar problems.

The name, IIRC, derives fromth e fact that the design team started with the concept of the Gas turbine, and slowly developed and evolved the idea. It's quite remarkable, if there is any future in IC engines, this has to be it.
