Nevawake Says:

Oct 27, 2009 - yeh i used an rd 350 2 stroke motor to make a twin system steam engine to power my bicycle for kicks when i was 17. Then i got given diagnosis adhd stim meds numb me man. And i have trouble sleeping. Now im just a dazed spaced out daytime coz of lack of sleep fukface. Get your sleep kids or ul go DUMB

Oct 27, 2009 - Where do you pick up a solenoid like that, as well as the "sensor" that he uses?

Oct 29, 2009 - Great bit of engineering, could a two-stroke engine that uses a reed-valve in its inlet manifold be converted without using the solenoid operated valve in the old spark plug hole ? Simply by using a steam injection system instead of a carburettor ?

Oct 30, 2009 - It was open. Taken off of the engine.

Oct 30, 2009 - It is not the mag holding it back. There is still a compression buildup with the air solenoid in the spark plug hole. Nice video though young man. Keep it up.

Nov 1, 2009 - Dan, I did just what you did with a motor i had after burning it up where it had no power to start. Then i applied steam from a homemade boiler and it really worked. My hat is off to you dude. Will be makeing Video Soon.

Nov 2, 2009 - It sounds as though you are describing a displacement lubricator that is common for steam use. The steam passing through the line going through the lubricator, enters the lubricator body through a small orfice. As the steam condenses water inside the lubricator and forces oil back out the orfice and into the steam line going to the engine. It only lubricates the piston and cylinder.

tdcadguy Says:

Nov 2, 2009 - To lubricate the rod bearings, either an automatic oiler, or a grease cup was commonly used. An automatic oiler actually works as a pump, powered in some fashion from a timing mechanism- usually an arm and follower. The lubrication system can have several lines going ot the various partsthat require lubrication. A grease cup is filled with grease and the cap is given a partial turn at given intervals. The cap forces grease to the spot requiring lubrication.

tdcadguy Says:

Nov 2, 2009 - Specially formulated oil is used for steam engine internal lubrication. It's called... you guessed it... steam oil. Displacement lubricators, by design, cannot be used with compressed air because they do not condense water and therefore will not displace the lubrication into the line. That being said, the lubricators for air tool use should work nicely for use on this type steam engine. IMO.

tdcadguy Says:

Nov 2, 2009 - WD40 isn't a good lubricant. Especially in this situation. By design, WD40 attempts to displace water.

tdcadguy Says:

Nov 2, 2009 - You make a good point on lubrication. However, with fuel/oil mixture type lubrication, the lubrication comes through the intake port, travels through the crankcase (lubricating the rod bearings), and into the cylinder. Injecting lubrication into the air supply through the spark plug hole only lubricates the piston and cylinder.

Nov 2, 2009 - should be possible to energise the solenoid valve directly with a bigger magnet and a coil

Nov 2, 2009 - i know now you can use two stroke engine lubee

motormaker Says:

Nov 3, 2009 - You are right, I had not thought of that. Some of these engines have ball bearings for the crank. However the rod bearings would still be dry. I would think you could install a oil slinger system like a briggs motor. Perhaps a dipper on the rod cap?

crazyfvck Says:

Nov 4, 2009 - Couldn't you just gravity feed oil into the port where the carb used to mount? That would lube the bottom end and top end just like the gas/oil mix used to, then be forced out of the exhaust port. You would have to have a decent size tank for the oil to be held in, but you could just use the original gas tank that came with the engine.

Nov 5, 2009 - ok, now remove the wheel and run it at 8000rpms :)

Nov 5, 2009 - You have only scratched the surface with steam engineering! Live steam is a different animal than compressed air. Building the boiler is half the battle of a cheap DIY steamer. In the spirit of this project, find an old car A/C condenser for your boiler. Those things are good for 200 psi. You'll need a feed tank to allow water to flow into one end. A BBQ gas grill could be your firebox. Water goes into the condenser, gets boiled by the gas grill, and steam gets piped to the engine.

InfiniteMushroom Says:

Nov 5, 2009 - You need a better load on the motor. Take apart some box fan and use the fan blades for a load. You'll get your flywheel and a load that increases fourfold as the RPM's increase.

signorelli21 Says:

Nov 8, 2009 - thanks for the video! Can you explain how you would set up the engine to run a ball/check valve? basically you would have it so the piston is opening the valve on the return stroke allowing steam into the cylinder right? so what kind of compression ratio do those little engines have? and wouldn;t your steam pressure have to be a bit higher than the cylinder pressure at TDC? the good solonoids are kind of pricey, lol.

GREENPOWERSCIENCE Says:

Nov 10, 2009 - You would need either a rod hitting the top. watch?v=L1Xe07WyAt4 DAN

BOBKB3NZX Says:

Nov 14, 2009 - a poppet style in theory would work. make a part to fit in the plug hole and use 3/16 drill rod, set the gap at TDC to open precisely and your golden ! do it it will be fun!

Cloxxki Says:

Nov 15, 2009 - Great stuff! But what we really need IMHO is a more efficient chamber expansion enegine sytem. Those crank shafts really only work on bicycles, because how our legs fold when they transfer muscle strength. Efficiency and torque can be tripled I would say if a more sensible sytem were to be used. Same goes for typical cars, needlessly spendy of gas.
