Re: new member introduction, also can i get opinion on ignition

Made another one tonight :D needs some tuning before it'll sustain without compressed air. I was limited to how much noise I could make tonight :(

Hopefully some decent runs tomorrow night :)

Re: Odd Metal jars

Pyrojoe - back on page 17 you attached a draft engine drawing to one of your posts. I'd like to build the draft engine but I don't understand the dimensions of the tubing used for the exhaust/inlet. Could your tell me the diameter please?

Thanks

Re: new member introduction, also can i get opinion on ignition

Good call, I will try that! Iam using 1/8 ID copper brake pipe for my fuel line + injector.

I just took delivery of some parts so I will build a new one with the correct size combustion chamber. Iam still waiting for stainless sheet before I start the m40

Re: new member introduction, also can i get opinion on ignition

Not as loud and I can still run it flat out without it flaming itself out. Only an 11kg bottle th...

Re: new member introduction, also can i get opinion on ignition

On Friday I ran my pj for the first time. I ran it for about 2minutes. On Saturday I ran it again but after about 2mins it started too die on me, I figured that the engine was warming and also the gas bottle was chilling and loosing pressure. I flipped the bottle upside-down to try out liquid. This ...

Re: new member introduction, also can i get opinion on ignition

Yes, for primary coil. Contact brakers are doing this job. Distributor cap and rotor has nothing to do with generating spark. It is absolutely waste of spark power if you feed high voltage through distributor in this case. Anyway, congratualtions! Its running very nicely! I tried this out and it wo...

Re: New here, first pulsejet in progress

And could you host your video on YouTube? I have no computer so Iam having to do all my internet stuff o...

Re: new member introduction, also can i get opinion on ignition

Thanks guys! Iam very pleased and I may have breathed a little of the smoke but we went outside pretty quickly. Iam still alive at this stage!

I love reading up before I attempt any new task, I hate going in blind :)

I'll be back tomorrow with more updates and more video!

I'll look into it :)
