Double Chamber (Why does it work so good)

Unread postAuthor: Novacastrian » Tue Oct 16, 2007 3:29 am

This is a double chamber Mini that i made quite a while ago, the only thing that i have changed is to include another air line (the white one) to increase flow of the pressure at combustion.
I like the design because it gives something nice to hold on to, and you can achieve a greater capacity without having to have a short and fat chamber.
I think that ignition at the bottom chamber gives many ignition points for the top chamber whilst also pressurising it at the same time (or there about).
This is the first or prototype design, can anyone see any real benefits or am i just dreaming :lol:
These pics are without the ignition plug/endcap.
Please comment, i want to find out why it works "so well".

In the words of a true genius, " I thought that the flow would be decreased, interesting"

When you fill your car with refined oil remember that it has been paid for with blood and guts, some from your own countrymen, most not.

would the genius by any chance be JSM? lol.
I'm not really sure why it works so well, but it looks very good.

Yes indeed the said genius is the aforementioned :)

P.S. I just spell checked " Genious" , the correct spelling is "Genius" apparantly.

Edit: JSR, can you spot the epoxy?

There seems to be a nice dollop between the chambers :)

I would tend to agree with your theory that the hot gasses from the first chamber provide an ignition source for the gas in the second chamber.

Again, no detail gets away from you my friend.
After straining my brain again i have thought that the turbulance could be helping too. Kind of like having a fan, without having a fan! (of course this would not be as effective as having a fan inside) Maybe i should add a fan.
Best of both worlds maybe. Hmmmmm

Indeed, the gas flow might serve as a monetary "fan" that further mixes the fuel and air before ignition

The flow volume might be decreased but the velocity of the gas may have increased.Don't know were I am going with this so now to trail off uniformly. . .shemm,de...shuck...

Is not the velocity of the gas corresponding to the rate of flow :?

Ohh JSR you know me to well. . .But at this point I am not intoxicated,still have all,well most of my motor skills :wink: .

Have you though that basically sheer volume has a role in it?

Thank you PCGUY for the spell check.
