very nice model

how they built the ignition?



[HEETGAS]

@MrLouitschi

I use a self made mini ignition system made from a circuit out of a gas lighter. You can read all about that on my web site: type my name on Google Search and my site is on top of the list (typing URL's is not allowed in this text box).

Go to the chapter "internal combustion engines" and then to the concerning page for this ignition system.

Hij is mooi Jan. Ik kom hem nog wel een keer echt kijken!

[spark300c]

wow, what rpm was it running at.

[HEETGAS]

@spark300c

I didnot measure the rpm yet; I think it is about 1200 rpm.

Now that is a loverly little work of art :-)

Very nice design and build.

Got to say I was questioning what the strength of the cylinders would be after a long run time.... But you have mostly addressed that below. Now to find some similar glass tubing and store it till I get the time to have a go!

Also have stirlings on my "list". :-)

Another superb work of art. Thank you.

1. Compliment for this little "Hellfire"-engine!

2. Just a pragmatic question: what might be the thermal efficiency compared to the regular boxer (horizontally opposed pistons) engined with two cylinders?

[HEETGAS]

@N9155E

I have no idea of the efficiency and efficiency is not an item at all with this kind of non pragmatic models.

Superb !! Big tumbs up !!

Maybe you can do verry long stroke engine like a ship diesel or something to give even more sight on fire. Great work of art from a great artist !!

That is superb! Very neat! Whats the life on the piston O-rings and type? Viton? Not even an initial lubrication of them?

[HEETGAS]

@mytmousemalibu

I don't know the material of the O-rings; probably ordinary rubber, but I am not sure. I found them in my material stock. Indeed I put some very few oil on them, but I don't know yet if that is really necessary. The temperature of the cylinder/piston keeps very low: some 40 degrees Celsius after 3 to 4 minutes running. I never let my engines run much longer because this is more than enough for a scuccessful demonstration I think.

-What kind of glass are the cylinders ?

[HEETGAS]

@robinhooodvsyou

I found this glass in my scratch box accidentally. For sure it is not very heat resistant Pyrex (not necessary apparently) but also not the very common and soft soda lime glass; anything in between. The wall thickness must be at least 1.25mm to withstand the combustion pressure and the tolerance of the inner diameter must be 0.2mm at the most.
