1/4 scale galloway gas engine model
« on: August 27, 2009, 09:24:20 PM »
heres a video of a hit and miss gas engine i built awhile ago

the castings are from richard shelly.
it has 8 inch dia flywheels, the bore and stroke are 1 1/4" x 2".
instead of a spark plug it uses an ignitor for ignition.
what you see in the video took 40 hours to make (from raw castings)
i have 6 model engines running and about 12 or 14 more to build.
i also have 5 full size engines to work on as well............i just love hit and miss engines of all sizes.

Very nice Engine you've built there Chuck:- sounds very sweet  :thumbup:. Do you take your engines to shows ?, ther's a yearly show held near us in the UK, they call the 1000 engine meet, been a couple of times really enjoy it.

Have fun

Nice work and engine :thumbup:

How does that ignitor differ from spark plug ? Does it use engine's piston to produce spark?

aermotor8 thanks for the link. I've read it, but it provides only a hint of that process (and devices related). Still can't understand how it works . Any thing that clarifies it would be appreciated.
