Do you know what four stroke means?

[crofty1984]

Was just wondering about what the level of technical knowledge is on PH. Thought this would be interesting question to kick off with.

[VinceFox]

Yes, and frankly if i didnt i'd probably be in the wrong place.

[ThatsWhatShe]

Yep.

Suck squeeze bang blow.

[budfox]

Yes I do.

Or, less umm, lowbrow, inhalation, compression, combustion, exhalation.


Works on women too.

I went for no idea.

It's probably something to do with sex.

Induction - compression - ignition - exhaust

That's a much better phrase.

Yes, it's a term used by women, to discribe men who come too quickly.

As in "he's a four stroke"

Explains why I had no idea

[Disco You]

What do you mean by the thermodynamics behind it?

[Pints]

Four stroke I understand, it's two stroke that I can't get my head around.

[METHS]

I wrote a 40 page technical report on the thermodynamics behind it and have designed parts that go inside a 4 stroke engine.

Rinsed and repeated for gas-turbine engines.

Bloody university.

Hah! I knew four years of engineering degree would come in handy one day!

[Wacky Racer]

Four stroke cycle



Two stroke cycle





HTH...

I know you didn't make the diagram, but it's not really an explosion, but combustion.

Christ.

Someone will be along to explain stoichiometric ratio next!

[MissChief]

I knew that a two stroke engine 'mixed' the exhaust and induction phases but I've never seen a cut away plan like that. Are all two stroke pistons shaped like that as opposed to the (relatively) flat-topped 4 stroke pistons?

The ideal air to fuel ratio mix for optimum combustion... can't remember the exact ratio though (I know it had a 4 in it)
