Video

The engine runs nice & throttles steady now we have the carbs adjusted. That clip of it running in the youtube video above was only the 2nd time we had run it & things weren't adjusted yet. Underload it'd be steady power but I'm sure it'd need some mufflers.

@brucerogermorgan2388, I’m glad you liked the video but the Villers you mention is nothing like the Tate engine we have in the video. Sure both are engines, & both are 2-strokes, but the Tate is not stepped piston, & also the cycle of the Villers you mention is completely different than the Tate.

@@nrowland56 You're quite right, of course, but it's just that the Villiers was another attempt to make a different 2 stroke engine,.

@brucerogermorgan2388 , thanks, & Villers attempts were much later than a lot of earlier pioneers. I can send pictures of an American twin cylinder step-piston cross scavenged 2-stroke that was built in 1905 for marine applications. There weren’t many standards in place on engines back then, & whether better or not, everyone had their own idea back in the day for a better engine, & with so many foundries & machine shops all over, almost every town through the US had someone making engines. We have a small museum/collection here of over 400 unique mostly 1-off, prototype, experimental, patent model, etc engines on display. Make sure to stop in if you get through this way, it'd be a good time & most everything runs.

My dad said he had a little trouble at first timing our engine as well. He said to time it off the intake valve. Start with the piston at TDC & time it so the intake is just opening. He said the cams are a little funny/off on the engine so if you try to time it by the exhaust first then they might close too early & there’ll be a little tiny bit of compression left in the cylinder at TDC when the intake valves open. Again don’t time it by the exhaust; instead try timing it starting at TDC with the intake valve just starting to open.

Thank you & I’ll definitely let you know when I get some of the “Type G” Avery Rowland engines cast. First ones will be in aluminum & then will be doing some in iron. On the Secor pic, I always liked that engine as well & thought it’d make a neat model. There’s quite a few different styles of the vertical ones, with the one shown on my namecard being what I think the nicest-looking version. Will have to dig out pics to send you later.

Thanks Nick

They mainly built marine engines but they did build a handful of stationary units too.

It’d be neat to power a printing press with one & I’ve thought about doing that. Of the 3 other known engines, all are smaller versions of this engine, 2 of them are running & the one is in parts. I’ve seen 2 of the 3 & they weren’t powering anything.

@zinckenstee; I’m glad you liked the engine & video. The basic layout of Tuttle’s engine is about the oldest known predecessor of the flame-licker engines people build today except that Tuttle’s engine in the video is an early internal combustion non-compression atmospheric engine with flame ignition. Fuel from the fuel tank above the engine is injected directly into the cylinders. Tuttle’s engine also has rotary valve air intakes on top of each cylinder. Air from the rotary intake valves is mixed inside the cylinders with fuel from the fuel tank above the engine. The flames in front of the engine are ignition flames. If this engine had a spark plug, it wouldn’t need the ignition flames on the outside to ignite the fuel/air mixture inside the cylinders. Thanks again & glad you liked the video.

Use fresh regular gasoline for the Type D engine. Good gasoline should be pretty clear looking when it's in the glass fuel tank. The more yellow or darker-looking it is usually means it's older/more spent fuel. On the other engine, the Type A flame engine, it's actually an internal combustion non-compression atmospheric engine. They were meant to run on the old MAPP gas but they stopped making that around 2008. They're really really touchy on the new map gas replacement or propane since neither has the burn-range flammability limit that the old Mapp gas did.

@@nrowland56 Thank you very much. I really like these engines I bought at an estate sale for Bill Yule in Ontario Canada. He had built many of your engines and now I’m the proud owner of 2 of them. I have the non compressing, the flame engine and the fearless engine. Very well made and I look forward to running them. This info is useful. Thx

Jason, thanks & I've been kicking around making a double-size or slightly bigger one of these electric engines similar to this one.

Thank you & she's 1 year & 3 weeks old in the video.

farhad sedri: That’s a loaded question in many ways to answer. The best way is keep researching & digging for things & see where it takes you & hopefully things will start to fall together. There are many different Brayton cycles, there’s many different definitions for cycle, stroke, etc. Engine cycles are constantly changing, etc., & there’s many different versions of history, there’s a lot of opinionated literature; list goes on & on.
