Ive had this idea for quite long time now but never actualy tried it out. I am just trying to see what you guys think about it. So heres a pic. Ask any question you want.
4% of propane is added tropugh the burst disk area using a syringe. Later on some kind of check valve could be created specificaly for the syringe. The combustable mix is then compressed by sliding the plunger forward and twisting to keep it at one spot.
Mini Hybrid~No Need To Measure!
you just gotta make sure that you have a way to secure that plunger so she wont pop back, what are you thinking for venting the chamber

Maybe I'm misunderstanding the concept, but I would think this would be nothing more than a conventional combustion.
Well I mean since you compress the whole mix you do make a hybrid. I will just vent it by blowing in it or something like that, Its just a mini. I will secure it using the guide (the white area on the diagram) I am sure it will hold the stress. Should I try this?
For a hybrid to be a hybrid, the mix needs to increase. Granted, by adding mix (air / fuel) to it, it increases in pressure, I just don't think it's going to work like you want it to simply by pressurizing the mixture that is already present.

no you are only pressureizing the mix not adding more to a smaller space you are however making the gun more complicated than it needs to be and will not see a signifigant power increase.
current projects: co-axial piston valve.Status DONE!
S.P.E.C.S update mk 1 construction begining in febuary all the maths for it are done plans are drawn up and parts are listed.
NEXT project:auto piston valve.

I see now. I guess I had brain freeze or something. The only problem I see is compressing it to the correct volume, which could probably be solved with some numbers or something.
The hell you won't. It's like a pneumatic. If you halve the chamber size but double the pressure, you'll get one huge amount more performance.thespeedycicada wrote:... and will not see a signifigant power increase.
Does that thing kinda look like a big cat to you?

I have had the same thought Felex, whilst it would work you would be limited to the amount of 'x' that could be achieved due to not being able to press down the plunger anymore. It would be a good way to make a Hybrid for people with no access to a compressor and or a hand pump.
I say give it a go a post your results.

Instead of making a mini version, why not make a large one. I understand that the 'x' will still be limited, but, using a larger chamber, a larger 'x' can be achieved.Novacastrian wrote:I have had the same thought Felex, whilst it would work you would be limited to the amount of 'x' that could be achieved due to not being able to press down the plunger anymore...

Interesting idea for a mini, sounds ideal for the epoxy-and-syringes construction I sometimes employ

This is the same thing as a generation II hybrid, you are just replacing the water with a piston.
I designed a hybrid, (but only built the ignition chamber before I had to stop because I was saving money for school), that employed two 4" tanks which had two pistons inside that compressed a mixture inside of them. Only thing was, I simply injected compressed air over the pistons to compress the mixture. It's almost like a captive water tank for houses with well supplies.
As for the piston, if you are using pipe, a test plug works perfectly. All you do is buy two, remove the two plates, obtain the two plates that are smaller than the I.D. of the pipe, install them on both sides of a rubber ring, and then re-install the nut. Perfect piston, and seals great, (also need to use a lube to get it to slide without fatigue to the rubber).
A simply ratcheting mechanism could be employed for your design to compress the piston as far as possible without it flying back and hitting you. A little mechanical advantage never hurt, either. Or, you could use compressed air in place of a hand. Either way, it's a well-accepted operating theory for a Gen. II hybrid.

This is a very good idea.
Too bad some people here dont understand it.
It IS a hybrid.
The point is that you inject fuel into a large chamber, then make that a smaller chamber, leaving you with a pressurized mix into a small chamber.
If you would have a small chamber, and then pressurizing/injecting fuel from the outside, like normal hybrids do, you would have THE SAME result.
Small chamber -- pressurized mix.
This will defenitely increase performance A LOT.
Like Ragnarok said: A pneumatic with a "small chamber -- high pressure" design is more powerful then a "large chamber -- low pressure" one.
