Lots of fiddly parts to make for this - even though it's a very simple engine. Makes you wonder how many go into a complicated one! Thanks to Will who drilled out and reamed the extra valves for me, as well as generally being helpful. Wouldn't it be fun to turn this is into a locomotive for the railway?? Lots more work to do first though..

Oh very well done Tim, that extra cylinder really does transform the engine. It's sounds so happy at the lower speeds: I could listen to that all day long. Perhaps you should do one of those 5hr films of it just ticking over, just like the ones of fireplaces, fish tanks or waterfalls. Personally I think this makes for a perfect stationary engine where it's wobbliness and high centre of gravity don't matter. Perhaps you could convert a compressor into a loco engine? Sturdy and compact and you'd have a nice output shaft as well. Many have high and low pressure cylinders of course.

fireless steam locos are not unknown - having a fixed steam plant and just a storage tank of steam on the locomotive to run from and think there may have been some air-powered ones as well - having a windmill running a compressor to fill tanks and then using the air to run a train sounds like a fantastic idea. Might be better to have the tanks fixed to the train and fill it from a storage tank so not so much fiddling around and heavy lifting.

For more torque you could split the air out from the valves on the left to the push stroke on the left and return stroke on the right, and split the air out on the right to the right push stroke and left pull stroke. It will use a bunch more air wont go faster but at least you will get more force.

Very good progress. You would likely need very high pressure gas bottles to store sufficient compressed air to power the engine. I think they would need a couple of thousand PSI pressure to get any worthwhile air duration. I cannot imagine a wind powered machine able to generate such pressure. There is a small car made in India which uses compressed air to power the vehicle. Look up Tata Airpod for more information. Well done Tim the two cylinders are working relatively smooth. What a fight to get the cylinder head off. Dave.

I think I the key to generating 3000psi tanks of air will be sourcing a BAC (breathing air compressor), perhaps on government liquidation from a fire department upgrading their self-contained breathing air equipment? I have seen them come up at auction on occasion in my area. Now that I'm thinking about it harder, you could achieve thousands of psi using a multi-stage compressor made from hydraulic cylinders, starting with larger diameters compressing into smaller diameter and shorter stroke cylinders and so-on until the desired pressure is reached. Lots of math would be involved.

If you want to store compressed air efficiently, you would need quite high pressures. I don't know how big your cilynders are exactly, but i would quess a stroke of about 70cm and the 5cm diameter. So that would be 1,35 Liters per stroke per cylinder. So at 100 RPM around 270 Liters per minute, if your working pressure is 1 bar (wich it won't be, cause you want power). A SCBA Tank at 300 bar (six liter internal volume at atmospheric pressure) holds around 1660 Liters ((Volume times pressure) divided by 1.1). So that would be gone in six minutes, if you have no leaks and want to depressurize completly, wich you wouldn't want, because then moisture can get into the tank. Also, for those pressures, a very expensive compressor is necessary, and the bottles aren't cheap either... So lets go for a somewhat cheaper option, 200 bar and maybe argon-cylinders (for welding and stuff). Those probably cost the same as a used SCBA bottle, but with more volume and usable air inside. The compressor problem is still there, but you can use a normal welding pressure reducer. Although you might want to combine multiple tanks on the loco, to have enough air... Just be sure you know what you are doing, because high pressure air is very dangerous!

If its just 200 psi i think most car climate-compressors can do that, although they don't move that much volume... For 200 bar i have no clue, probably something industrial, maybe for scuba diving?

@@wayoutwest-workshopstuff6299 Tim: I am REALLY enjoying your channel. Thanks so much for it.Remember how much power you lose if you use a pressure regulator. If you run your engine on, say, 50 psi air then at the end of the run, when your tank pressure is around 50 psi you will be using all of the energy in the air. But at the beginning of the run, you will be throttling the pressure from 200 to 50 psi. three quarters of the mechanical work you put into the air to compress it to 200 will be lost as heat and you will extract mechanical energy only from the last quarter of the energy you put into compressing the air as it expands from 50 psi to atmospheric pressure.
@jonathanherz3298
@jonathanherz3298 2 жыл бұрын
You could use the energy efficiently if you had a variable cutoff valving system, so that you take in much less 200 psi air per stroke (earlier cutoff) than 50 psi air (late cutoff). Variable cutoff is a very elegant solution (see Corliss steam valve - one of my favorite mechanical linkages ever) but complicated to execute.

Many of the mine locomotives used here in Western Canada at the beginning of the 20th century ran on compressed air until replaced by electric ones. Steam was too dangerous for use underground. Keeping it as a compressed air engine would make sense (and would be safer too) as long as you had a large enough reservoir for the distance being covered.

Another fabulous creation, Tim. I'm so glad I found your channel. The railway is looking better all the time. To transfer power to the wheels, have a look at some ride-on lawnmowers that use two discs either side of a rubber roller set at 90 degrees to the rotation of the discs. This is a combination clutch, reduction-gear and reverse in one. It changes the direction of rotation of the output shaft by pressing the roller up against one or the other of the discs. Old Cox brand mowers used this arrangement which was easily visible by lifting up the seat. Two old car brake discs and a small, solid rubber wheel attached to an axle would work.

Instead of filling the tank with steam or compressed air, you might be better off filling the tank with superheated water. Water at 250°F will produce steam at 50 psi. The steam expansion rate is 1700:1 You can use a fixed boiler, and plumb hot water into your on-board tank. That way you don’t have to move the boiler. This is what was known as a “fireless locomotive”. Of course, at that point, you might as will just mount the boiler on a car; and take it with you. en.m.wikipedia.org/wiki/Fireless_locomotive

Fun fact- this is very much like how a "Heisler" type steam locomotive is set up! The pistons are set horizontally either side of the locomotive, much like you have yours set. When steam is applied, it turns a flywheel and driveshaft. The driveshaft is coupled to the 2 bogies on the locomotive, which then drives the locomotive forward or backward when the pistons are in motion. The Heisler is not known for speed, but for its torque, ability to climb steep grades, and tractive effort.

Another option to consider rather than steam is an air reheater before the engine. The air gets cold as it expands from the tank, and loses some oomph in the process. Some compressed air trolleys used little coal stoves or bottles of nearly boiling water to do the reheating, though you can likely get away with pretty much anything that can raise the temperature. My personal favorite idea is to pair an air engine with a biochar kiln, lots of heat to spare there!

Maybe a Loco with an electric motor that can go in forward and reverse with a flip of a switch while you’re generating all the power you need on board. If you want to compress air at a high pressure in some welding tanks I know that air-conditioned pumps in cars can get you around 300 psi without a problem you could probably even run one on your windmill to compress the air ….. but we both know steam would be a lot more fun!!

One way you could make the engine reversible would be to modify the cams to work like slip eccentrics. The cams would need to be free to rotate on the flywheel shaft and there would need to be two stops to limit the amount of rotation. This gives the cams two operating positions according to which direction the shaft is turning. The two stops need to be set so that the cam timing is correct for each direction of rotation. A simple way to change direction is to turn the flywheel by hand in the desired direction. The friction of the cam followers against the cams will cause the cams to remain stationary until the cams come up against the stop for that direction of rotation.

For reversing the flywheel direction, could adding air to the other side of the cylinder work (i.e. push the piston back into the cylinder)? Sure, less power, due to smaller surface area, but it would go backwards.

@@theothertonydutch yeah, you'd need valve gear - not necessarily Walschaerts, but anything along those lines would do. It is, however, quite a complex installation, especially with two cylinders.

What he mentioned in this video was that there would be far less surface area on that side of the piston head for the air to push on, so it would produce far less power, and he didn't think it was worth the effort of trying

If you have a stream or river nearby, you could build a trompe, a water powered air compressor with no moving parts, and use that to power it. You would need a high drop in the water to get high enough pressure, though.

You project is coming right along Tim and looking great while doing so. If you want to power things with it in the shop how about a rubber drive wheel that contacts the flywheel and then runs a belt or chain to the "driven" device? I can see a large blade sawmill, sander or drill press being run by that machine.

For a place with access to a trompe or the ideal conditions to build one for access to high volume low pressure air I could see that as a relatively viable source of energy for potential electricity generation. Not the most efficient but generally speaking free to us since gravity and water would be doing the work to pressurize the air.

I like the trefoil detail on the mounting plate and the beautiful cutouts on the valving pushrods. Remember steam /air trype engines are inneficient. Try putting little blades on the perimiter of your flywheel and use your compressed air to drive blades. Air piston is inneficient, too many reciprocating parts.

Before you jump to steam power you should consider making your joints and moving parts less cantankerous. One of those pivots seems like its banging every time it contracts. Threaded bolts arent the best option but its cool to see that it works. If you do jump to steam however you're gonna need a big enough boilerwith a safety valve.

Hey Tim, keep in mind the Auto Industry already solved this. What you need now is an old stick shift transmission or gear box. Petrol Engines only crank in one direction so revers happens by changing the gears to make the output go in the opposite direction. Granted with this set up I don't see you going much being gear one and revers but it should help save you time.

Fascinating work Tim! Just to throw a bit of a curve ball at you, I don't know if you're familiar but there is a train; British Rail Class 139 that is driven by the energy stored by a flywheel on board. Not sure if it's even feasible but it might be food thought.

7:31 I think some angle iron welded up in a large box should be really cheap/ free if you look in a construction site dumpster. Also I figure you'd need at least 150PSI to drive anything, the engine and boiler will be heavy.

i know a way to make a simple reverser gear box that is in line that could be clutchless so if memory serves corect, you can take a diferential (preferably a locking diferential) 1 axle is imput and the other is output, you lock the gears together to move forward, to reverse you just lock the carier portion of it (could lock it from the bull gear) cant wait to see where this project goes/

With the low rpm and hopefully higher torque + two wheel drive on this loco, I think an old tractor gearbox from a small tractor with 2 or 3 gears, and a reverse would work well for this project. It might be around $100, at least when I looked for one online in the area near me. However, I don't know the pricing in ireland, where it is probably more expensive. Good luck, and love the video!
