Well with a more involved cam mod, you could boost efficiency considerably. If i understand it now, steam is fed thru throttle to sparkplug and exhaust valve opens on every upstroke? so it is venting steam from the boiler even while piston is rising so 1/2 the steam performs no work. if you double the camlobes on intake and exhaust and feed steam in thru intake, 100% of steam will perform work

@rronmar This is true....but moving valves is "work". It's inefficient like one of those little rc glow engines that spit out as much as they burn! It was just a backyard project. Thanks or the comments

Well done on the demo! Was this engine modified from a four-stroke? A conversion along such lines might use a custom camshaft for inlet every downstroke of the piston, exhaust every upstroke.

Thank You. You have pretty much described the conversion, the details of which are listed in the original comments.

@mememojo  Probably the same reason you watched it........too much time on my hands

[gwseymour]

Yup. I only use it for short runs, with lots of water. Nuthin worse than laying in the hospital with no skin.

This is a very interesting conversion. Thanks for sharing it with us, at least your doing something productive with your time.

B&S are splash lubed, at least at that small size, they won't run for long inverted. oil contamination could be a problem. putting large vent holes in the case and a larger oil sump to allow liquid water to separate might help some but that will be a problem unless the case is opened up more and engine switched to dry sump and pressure lube. exhaust fed to a condenser and a feed pump back to boiler would allow very long runs with little water consumption. backwoods battery charger:)

awsome gota try it thank you ive ben wondering where to start

[mrswizzful]

@mrswizzful or atleast into a collection bowl at the end , then it could be used as a rele good off the grid generator

[mrswizzful]

I had a gr8 idea for this .. take the exhaust , pit a pipe to it sprialing it back to the main tank .. thru a cold water bath? so it continues to run without needing to be refilled =) worth a shot!

[MrRazmushenriksson]

What did you convert? The camshaft?

@gwseymour we fear what we dont understand =3-
