Model Engine running just off a naked flame

[JasonBModerator @jasonb]

It looks like it has a bit of both. The ones that run from gas tend to have the tank at the flywheel end as can be seen in the photo, this is how the kit from Polly Eng is configured. I have seen others with various spirit burners with the tank and wick burner at the head end which can also be seen in that photo.

Flame gulpers have been around for a very long time. Here is a model from 1904

 

Love to see a video of that running, thanks for the photo.

The square brass part with the large hole, that’s a water reservoir/radiator?

[DiogenesParticipant @diogenes]

Yes, that’s right, was common full-size practice on so many ‘utility’ engines of that period as I’m sure you know.

[Howard LewisParticipant @howardlewis46836]

Being of modest power, and speed, many engines of that era, and type, relied on evaporative cooling, just needing an occasional top up to replace what had either evaporated or boiled off.

Some times referred to as “Hopper Cooled”  No fun being poked at our esteemed antipodean friend!

The preserved examples, now seen at shows, will probably run all day without much attention, since they are, in most cases, unloaded.

I’m possibly one of the few who has driven a Fordson TVO tractor and been paid for it. Farmers in the Yorkshire dales needed one tractor most of the year, but several at hay time, so all sorts of old crocks were hidden away in barns. The Fordson had a radiator, but it didn’t start to pull well until it was boiling. The radiator cap was a big oval affair, and a bucket of water was positioned in a convenient place so it could be regularly topped up. You didn’t stop the engine as it had no self starter.
