Diy scratch built home made flame licker #2 converted to propane

Just another video of the flame licker only this time converted to propane and with graphite pistons..

[@howardosborne8647]

Nilamotk, I've mentioned limited valve timing on your previous video on this engine. The nature of this simple piston valve design is the main performance limiter. This design dictates that the valve opening/closing events are symmetrical around top dead centre and bottom dead centre. A valve mechanism driven by a cam and pushrod or rocker arm permit assymetry to be dialled in on the valve timing. Flamelicker engines with asymmetric valve opening perform far better than this design. I have built both types and this piston valve type are really fiddly to get good performance and long runs from.

[@nilamotk]

Maybe one day I'll make one with a slide valve and cam instead.

[@AwsomeVids83]

Honestly one of the nicest flamelickers I've ever seen. You did a great job on that engine! I wish i had the tools and skills to create something like this!

[@nilamotk]

A. Zak thanks, im proud if it too. Lots of dicking around....

[@leerman22]

Hank Hill approved!

[@azmiavcioglu8649]

Remove one of the flywheels, it will run faster.

[@hyperbutt1226]

Pretty cool

[@malcytull]

Brilliant job, thank you for sharing your work with us.

[@lukanikic4950]

How come you're not posting any videos anymore?

[@EdwardTriesToScience]

Pretty cool, I wish I had a lathe to do this stuff (along with glassblowing stuff). Might make one some day. I guess it was a bit hard to do as you has to trial and error everything until it runs properly.

[@b-rad3937]

Yea I'm sure he had quite a bit of trial and error . .I've been wanting to make one

[@b-rad3937]

Or a acoustic engine

[@b-rad3937]

Thermo acoustic engine I mean

Awesome work I’ve just found your channel and watched a couple of your videos and I’m really impressed

How do you fill it with propane? Did you use a propane torch tank to fuel it?

[@nilamotk]

That silver knurled cap used to be for fuel oil, kerosene or whatever. I remachined with a hole in the center of it to incorporate a rubber ball and a spring. The spring seats the rubber ball and hold the pressure back. I then made a filler adapter out of a torch to go on a propane torch bottle, I drilled the orifice out so it could feed a good volume of liquid quickly. And then made the tip with a small tube and a big rubber seal. You'd push the tube into the hole, it would push the ball out of the way and then you could fill it with propane. When the tube was removed the spring, and propane pressure would hold the ball seated and hold the propane. It would hold propane for about 2 or 3 weeks. It had a very slow leak so I would just fill it a bit for each run. Butane also worked well.

Hello you to springs into the tube it will not turn off the fire

[@nilamotk]

song anh hotel i tried that but it caused more problems.

[@MATECH-ds3vw]

nice

[@TheHengeProphet]

This doesn't actually seem like a bad design, but I think the thermal capacity of your cylinder is too high. The colder you can get one to run the more efficient it should be, so if you increase the surface area of the cooling fins on your cylinder (by either cutting a groove in the middle of them to double the fins or just by thinning them out a bit), it should both heat up faster and run cooler overall.

[@nilamotk]

It will burn a whole tank of fuel before it over heats as it sits, but yea you're correct. But seeing as ill never have it running that long im in no mood to rebuild it.. lol

[@philipgrobler7253]

Well done, the aound this engine makes, music!

[@MrChuckmason]

Really nice work!

[@xSilva666x]

Can you get me the planes please?

[@nilamotk]

Silva0197 there aren't any.. its built from my head lol. Sorry man.

[@xSilva666x]

no problem men

[@xSilva666x]

but could you just give me the measurements? to an email?

[@MATECH-ds3vw]

i give you this plan

[@MATECH-ds3vw]

you contect whit me ([e-mail]) this is face book]'
