steam engines have adjustable valve timing. the longer the intake valve is opened the more torque you get and more steam is needed. A steam engine operator would reduce the open time when the train is at speed and increase it when the force is needed to accelerate or go up hill. my advice, adjust the lobes on the cam shaft. the intake lobe should open the valve as soon as the piston crosses the top dead center and close it when it get's close to the bottom the exhaust should open as soon as the piston crosses the bottom dead center and stay open for as long as possible this should provide the maximum torque and given enough steam should move from first gear without using the clutch

There is a guy who made his car to run on compressed air, he has the air leaving the first cylinder is fed to the second cylinder, then to the third and forth. this gave him a lot more run time per tank of air and each cylinder was adding power to the system. i think he was getting 15 minutes of run time at 20 mph.

[@bartjanflikkema]

@@ojmbvids that's what I was thinking. For sure making it rotating twice as fast will open it at the correct rate as wel, but as it is moving twice as fast, the opening time is only half the normal time. This problem doesn't exists with the double profile. More opening time is more torque, and in the end more power.

[@neok1996]

There will stil be a dead spot from 180° on the camshaft So i think it will only open when the piston is on the upper half of the cilinder Piston down -> 1/2 valve closed 1/2-> up : exhaust Up -> 1/2 : intake 1/2 -> down : valve closed (You lose 1/2 of the piston displacement/power) For a single cilinder When with dubble lobes It is Piston down -> up : exhaust open Piston up -> down : intake open And it works with multiple cilinders

@@kruleworld Actually what it shows is how inefficient "external combustion" is, not what the density of the fuel is. Compressed air in this case isn't a fuel just as steam isn't a fuel. Coal or other burned substance is the fuel in a steam engine and electricity in the form of an air compressor was the fuel here. You're better off using the fuel directly (internally). Which is why we don't use steam engines anymore.

[@rayceeya8659]

Ahh man. You're doing it the hard way. You need to start with a Trabant. Two stroke engine. With side ports. Separate Jugs instead of monoblock. You inject the compressed air/steam through the the spark plug hole. You need to figure out a way to seal off the intake port and then it's just a matter of valve timing through the spark plug hole. Some conversions use a simple punch valve that opens when the piston strikes it. That's got some obvious wear problems. I would go with solenoid valves and a micro controller for compressed air. Steam is going to require something more robust. The key though is in a two stroke, the exhaust doesn't need any modification at all. It just lets the steam out when the piston reaches the bottom of the stroke just like a steam engine. A good place to start for your steam injector might be to try retrofitting a TPI fuel injection system. Solenoid valves are built right in and just need to be switched on and off. Not sure they can handle steam but think of the fun finding out. Also oiling is going to be an issue. So yeah, that's where I would start. A Trabant, a 2 cycle engine. Block up the intakes and figure out how you inject your steam to the cylinder. Steam punk car. I could probably make it work in about a month with a steady supply of cheap beer.

[@Droningonuk]

[@Triplex5014]

The flatplane crankshaft makes it possible that the engine could stall with 2 pistons in TDC and 2 pistons in BDC. An engine with a crossplane crankshaft (with minimum of 3 cylinders) would perform smoother and get rid of the possible stalling. A classic steam locomotive has 2 double acting cylinders which are 90 degrees apart, so a steam locomotive has 4 power strokes per a revolution of the driving wheels.

[@baklys]

If you are going to run the engine on steam, just let in the steam for a few degrees. Steam behaves quite different than compressed air, IT EXPANDS EVEN AFTER THE INTAKE VALVE IS CLOSED. I have some experience with steam engines, have one myselfe. So if you make the intake valve open like 0 to 15 degree after TDC, and let the exhaust be open from 170-360 it should be alot more effective. Good luck! PS, a steam engine will not be powerful on compressed air, as I wrote, the steam expands during the power stroke. I really hope you will read my comment, and start working on the camshaft with the angle- grinder. Then PS again, if you change the timing sprocket on the camshaft to one the same size as the one on the flywheel, it might be easier, if not, you need dual lobes on the camshaft. :) :) Thank you for posting videos, a great channel! Regards from Norway.

[@28YorkshireRose12]

The problem is not the air pressure, it's the volume of air that you have underestimated! Have you ever noticed how steam engines have large diameter steam pipes? And a colossal sized boiler? All for a relatively low power output. That's because you have to admit a lot steam into the cylinder, at a decent pressure, with a big reserve volume behind it. In this engine, as you have it configured, you're trying to pressurise two cylinders at the same time. There just is not a big enough volume of air to do that. Remember also, the smaller the diameter of the cylinder, the greater the pressure you need to move the piston. What's the output pressure of your compressor? - About 10 to 15 bar? A modern steam engine's boiler would be at least double that, so, in backyard mechanics, you need to double the pressure, quadruple the volume, and have an almost unlimited reserve of air, to make it work. How about getting hold of a mobile compressor of the type used by road construction workers (rock drills, jack-hammers and the like)? They at least can sustain a large volume and pressure. Probably not enough to the make the car a viable proposition, but maybe enough to prove the concept? Then also, at least, if the car has the capability to tow a trailer, you could tow the compressor behind the car, and go for a drive - assuming the engine can develop enough power to tow the compressor!

Something I dont know if youve looked at yet ? about 40 years ago , Volvo experimented with a gas expansion engine . It ran on something similar to dry cleaning fluid . The fluid was in the crank case as well . you injected it cold . an MSD ignition fired it , the fluid fired , and rapidly expanded , pushing the piston down . After the fluid cooled , it was re-pumped into the combustion chambers and re-used . The whole Idea was an engine that didnt use any fuel . sounds crazy , but I saw a video of it running , now I cant find any trace of it . I know the biggest problem they had was keeping the gas and fluid from escaping out of the crankshaft and valve guide seals . For a project like that , your the man . If you were serious , Id even come over from Canada , and help you with it .

Three is like a few problem here. Firstly the air is forced in the direction of the valve spring. Some air is probably leaking right throw. Secondly. It loses way to much volume.

OOOHHWWW! TOO BAD you did not feel with your own hands how much torque you loose on the turning over of the camshaft! Most energie is lost cause those valves are needlessly pressed shut by way too heavy springs for this job! The beauty of steam/airpressure is that it closes the valves from within, so only very light springs will work and thus your project would have been much more successfull. Next problem is the inlet manifold that should have been 4 little high pressure tubes in stead of the original bulky thing. You like to keep pressure up by small pipework, not big ones!

[@zwz.zdenek]

You really need to offset the two remaining cylinders 90° so that it can start on its own from any position. But if you ever want to run on actual steam, you need smaller cylinders at higher pressure. Water will not boil fast enough to feed large, low pressure cylinders like that. You also want to close the intake valve way before the piston reaches the end of the power stroke. Taking in all the pressure near the end is wasteful. Consider cutting the intake cams in half so that the trailing half of the cam is missing. The valves should slam shut at about half of the stroke. (It would be more efficient to close even sooner, but difficult to do with just a simple welded camshaft.) It would be great if two of the four intakes could be disabled on demand to reduce steam use while cruising.

[@mrdummy_nl]

You don't even need radiator for it, because steam cannot got very hot like fire. Remove water pump will have less friction too. But i thought you should push compressed air in the holes of sparkplugs (simulate explosion part), let intake valves closed and timing the exhaust valves in twice speed open/close. And add electronic air/gas valves with mechanic driven 4-way switch to open/close each valve. Complex idea indeed, but it might work too.

every NASA engineer on the comments is saying to fit a 1:1 pulley between crank and cam,.....NOPE...we dont need compression or firing strokes where all the valves are closed on that cylinder, it will cut the motor's efficiency in half...the way they did it is the best way....just two cycles intake and exhaust....now they need to regrind the cams to remove any advance or overlap. intake should open at tdc and close at bdc or atleast very close. exhaust its the opposite and should stay open until intake starts opening....camshaft lobes should be steeper also, valves should open fully and close immediately very fast... also they need to take into account that the pressure they use is not enough to push the valves open by it's own, if that happens they need stiffer valve springs wich will eat their angle iron lobes....

[@jordanoneill82]

you need both volume and pressure. figure out a rev limit you are happy with and start from there. displacement divided by 4 and then multiplied by 2 will give you cc's required per revolution, multiply that by your desired rev limit and you'll know how many cc's of air required per minute are required to give you full rev range example: my engine is a 3.0l 4cyl engine so each cylinder is 750cc, being 4 stroke there is 2 combustions per revolution so 1500cc of air is required per revolution. at 3000rpm you'd need 4.5 cubic meters of air per minute. for every additional bar of pressure you gotta pump through it to keep it running you can double the volume. it'll take 10 cubic meters of air per minute to run effectively probably. you'll need a LOT of pressure for it to work mate.

I built a miniature six cylinder engine designed to run on gasoline but decided to run it on compressed air, as my cam was running at half engine speed, I had to do what you did and make a double lobed camshaft so that air could be admitted into the cylinders at every top dead center. The six cylinder four stroke engine has two pistons coming up together every 120 degrees so my engine really became a "three cylinder big bang engine" I made all the cam blanks (12) in one go on a lathe with special jig with a degree plate to be able to gradually develop the cam shape by shaving material off with a 10 mm end mill running in the chuck of the lathe and rotating the blanks four degrees and then shaving more metal off. the whole assembly was moved closer to the end mill for each cut to be carried out and generate the cam profile. Well done guys,cheers from the UK.

@4:39 instead of double lobing the cam, why not just spin it twice as fast by changing the gear ratio of the timing chain?

I suggest using the more advanced steam boiler design that heats up almost instantly instead of taking forever to build pressure.

Also the outlet stoke timing is off if you ask me so your engine wil not have the power it needs to move. You should check the stand of the pistons when valves are opening and closing.

You are shooting steam into all cylinders simultaneously. The intake valves are only designed to hold pressure from the piston side. The air pressure from the tank is pushing the valves open and killing your power. 12 volt Pop valves in the spark plug holes is way better. This also allows you to adjust the timing and duration of the power stroke. Grind the intake lobes off the cam and leave the exhaust as is. Use cam position sensors as a power source for the pop valves. As the magnets in the balancer spin past the cam sensors they will send a shot of 12volt to the corresponding valve and open it. No battery needed. Simple and will develop significantly more power than pressurizing the intake and trying to make the valves work with pressure from the wrong side. You guys rock! Great entertainment keep up the good work!

offset camshaft lobes 90 Degrees? NIET Tovarich, offset 180 Degrees!

Smaller camshaft pulley? So it's not a 1:2 but a 1:1 then you get rid of more strokes

[@French20cent]

Okay so now I'm asking myself if reducing the diameter of the camshaft pulley (to make it do revolutions twice as fast) would have led to the same result as adding lobes to the cam. It's 1am, why brain no sleep ?

Put a turbo jet engine on it so the exhaust feeds the pressure side with the turbo blowing straight into the engine with fuel so it makes better compression
