JohnnyQ90 Are you an engineer? I'd love to see what you could do with A motorcycle or car engine. Geez you could get every ounce of power out of an engine just by your ability to analyze and make some tweaks. I love your videos and channel!
What's the difference in this one compared to the one you got? www.banggood.com/Eachine-ET1-STEM-Upgrade-Hit-Miss-Gas-Engine-Stirling-Engine-Model-Combustion-Engine-Collection-p-1430588.html?rmmds=detail-top-buytogether-auto&cur_warehouse=CN
I=P/V so assuming that bulb is running 10v or less should be fine, I can't imagine it's running any more that 10v. Say it's running 10w at 10v that's 1A plenty for a smartphone. Assuming you asked for just 5v that same 10w output =2A. It likely wouldn't be a fast charge but I'd image its be capable of charging most devices especially if both governer springs were re-fitted to allow it to rev higher again. (not a very eloquent summary I'm afraid)
LarryM a watt is a watt. It's a measure of power. An amp is a unit of electrical current. If that engine is capable of producing 10 watts of power, then at the 5v needed by a smartphone charger, you'd be looking at about 2 amps. (Volts x amps=watts) Of course, you'd need DC current, and that alternator is AC, so there'd be some power loss in the circuitry needed to rectify and smooth the output, but 1.5 amps wouldn't be an unreasonable expectation.
What a coincidence, I was around a few hit and miss engines today. They were running pumpjacks. They usually run on oilwells that are too remote to get electricity out there to them. They are fueled by the gas from the oilwell itself. There are still plenty of them around. There are other ways to run a pumpjack, but I think these are the neatest and boy they are loud as hell.
I hope you are adding a little oil to the fuel for upper cylinder lubricant! Running much better, but take one governor spring off to slow the hit and miss right down. Use LEDS to draw less load from the dynamo too.
Technically speaking, this engine is one. Hit and Miss engines like this operate on a four stroke cycle when they're hitting, they just govern their speed by interrupting that cycle. Most of the time, they do this by holding the exhaust valve open, while the intake valve uses a spring so weak that the piston moving down will pull it open whenever the exhaust valve is closed.
It only stands to reason a hit and miss runs smoother with a load. As it pulls the rpms down the centrifugal weights stay closer to the main shaft and causes the valve to open for more fuel making the engine fire every stroke. Fuel consumption increases. The engine would by nature be smoother as the counterweight of the crankshafts is balanced by the ignition of fuel.
@@bryanthornburg8636 that depends on a few things 1 it does away with the rolling resistance of rubber tyre, and 2 depends on how many magnets and how many coils. would probably stick to 3 phases
@@TheShack444 my point still stands, it would not be any easier on the engine, and it wouldn't be as efficient because the magnets would be spinning in a way that produced much less power.
@@bryanthornburg8636 i guess we are not going to agree on this one! you could add magnets to both fly wheels! in my eyes does away with motor windage! bearing resistane, and rubber resistance, need some one to try it! probably the best way. my Father had an idea with a large water wheel. rather the fitting a dynamo/generator, he thought of fitting loads of magnets around the outer diameter of the wheel. the more magnet means slower RPM ... the thus making the water wheel the rotor of the dynamo...
I assume you put the original govner back on when you installed the motor? If so it's amazing that a motor acting as a dynamo induce enough drag to act as a mechanical govner when the circuit is closed. Energising the magnets I suppose?
Uber Micro Repairs The flyweights maintain engine speed regardless of load. Unless you load the engine so much that the belt slips, it stalls, or it simply fires constantly and can't keep the set speed, it'll keep the governor speed automatically and fire as infrequently or as often as needed.
cool. a 10 watt dynomometer. that little motor sure got on the governor with that small load. neat trick pulling that spring to slow it down. i am thinking about ordering one but reveiws show it takes 3-4 months to get it.
I remember seeing these since I was a kid at the County Fair . How many watts load (bogs down to continuous fire Gov deactivated). can this take with; this setup, stock, and heavier than stock gov. spring , what is the max load /gov spring combo??
I loved your engine, sorry it's so expensive on Banggood. It seems to be able to produce even more power. Did you try a larger roller on the generator shaft? Seems that max power is somewhere in the higher revs area.
Johnny, I've had one of these (blue one identical to yours) for a couple years. Since it was brand new I have not been able to get it started. Can I please ask what fuel you are using? Is there a website/UA-cam page/Facebook page that I could find some help getting it to run? Thank you.
if you get sine if that cheap sorta rubbery woven drawer liner, you can test things like that on your bench by putting a square of it down under the engine. its cheap and great all around the shop
Jimmy's Tractor - Lot of creative engine modelers in California. Go online and check out Bay Area Engine Modelers. I think it's not nice to poke fun at other states because it just adds to the problems this country is facing now.
@@tomhare3190 uh, I think it's ok to poke fun at CA. I lived there for 5 years and love the state, just not those that have made everything so difficult. There comes a point when you make things so costly, that's it's cheaper to do it in China. Last time I checked CA and China share the same planet, difference is China has a very different set of regulations.
I just received mine in the mail today. I noticed the water hopper does not surround the cylinder, possibly making water cooling pointless? How long do you think it can safely run and do you think water helps at all?
When I first seen ur lil hit miss I was like dam that has got to be the fastest one I ever seen then idk much about them to no she was cruising i was well mabe its cause of its size then boom u show a update on the cool lil motor super cool..
Get a small brushless motor and rewind it with thinner magnet wire, it should be way more efficient than those with brushes that have lots of friction.
Wonder if it is possible to add some sort of magneto like some of the full size engines had or would it just not be practical with something so small or not possible given the small size?
You can but it will struggle. There's too little momentum in these little flywheels, and the power stroke too small. I have seen em power their own ignition and driving a full sized 5 watt led lamp but the engine was unreliable and produced wavering amount of power that sooner or later went bellow its own ability to power itself.
@@laharl2k Ah, like to govern the speed of the engine you mean? It has a centrifugal governor on the side of the flywheel.. What I meant was to use the power coming from the generator to power the spark plug in place of the batteries. I just didn't know if the generator would be spinning fast enough to generate enough voltage to drive the plug.
I would like to see this running a brush-less dc motor like a drone motor with a alternator rectifier circuit and a capacitor on it. Would smooth the engine out even more.
Yves Baggi These engines were normally very big with huge heavy flywheels. A flat belt would turn something like a log splitter, flour grinder, milk churner, etc. Because they skipped power strokes, they ran cool, used less fuel, and simply relied on the flyweight governor to maintain speed which was a simple setup to build, adjust, and repair. The huge flywheel stored rotational energy and the piston only gave it a bump every now and then to keep it at speed.
probably not even 10 watts... it might work better with a small pulley (as used on real hit&miss engines) + generator than how it was done as it has less mechanical advantage this way. Then again you'd need a larger generator to get as many volts out... so you might not be any better off.
Nice Video, thank you. I ordered one from banggood but it will take a few month to restock this little engine. I would like to built a stand for it in the meamtime. Does someone has the dimensions of the engine for me? Also for the ground plate and the wholes in it, to conect the engine with the stand. Thank you, Manfred.
It doesn't hurt it... low RPM on these engines is actually less stressful, metalurgy when these engines were designed couldn't handle higher speeds and temps. Typically you don't see hit and miss engines running over a several hunrdred RPM which is why they always have heavy flywheels... to store up a bit of energy so they don't have to hit every time and if loaded up they don't stall out between hits.
flippy dude He added a weaker spring. The fly weight spread out against the pull of the spring when the engine spins at speed equal to or greater than the desired speed set by the user. When they spread out, the hold the exhaust valve open to prevent the engine from firing and it simply freewheels with the rotational inertia of the heavy flywheel. When the engine speed eventually drops below the desired speed, the flyweights come back together with the pull of the spring because the centrifugal force isn't enough to spread them apart. They now can't hold the exhaust valve pushrod off its cam lobe. The exhaust valve closes and operates like it should, and the engine is able to complete a 4 stroke cycle and apply torque to the crankshaft. It will complete 4 stroke cycles and speed the flywheel back up until those flyweights are forced to spread out and hold the exhaust valve open again to let the engine freewheel at the desired speed. This continues over and over again. You can set the desired speed by changing the mass of the flyweights and the strength of the spring. A heavier weight will make the engine spin slower, as will a weaker spring. These engines are meant to spin very slowly and produce a lot of torque. That huge heavy flywheel stores a ton of rotational energy which allows the hit-and-miss operation. It creates a lot of torque. Horsepower is a power rating, so it's force over time. These engines are low horsepower rating because even though they produce lots of torque, the speed variable in the equation gives a small output. These engines would have been used to run flour grinders, log splitter, milk churners, large wood saws, and other devices.
I'm always amazed by your skill. The video production is top notch too. I love to watch the metal lathe change a cylinder into something you designed. Do you have a spec or just eyeball everything? Are the milling machines cnc or manual?
You could light up 5 led's and have loads more light compaired to that old bulb. Try and power dynamos that in turn power the thing that's powering them.
Actually it's not about the spring on the govna' it's about weight. This design of engine simply cannot be built (at 1:1) out of such light materials as this is because it would simply bounce off the ground. Even the actual engines themselves can sometimes "walk" on the stand if it's too light. Suggestion: add a lead platform.
You can get the engine here guys ;)

add a power supply so the generator also starts the engine
He means a electric starter powered from the electricity the generator makes
I've always loved hit and miss engine and flywheel engine and seeing this small on here is just pretty cool.
It actually runs smoother whilst generating power.
Thats how these engines work, when under load they dont hit and miss.
Finding myself watching these vids all day
Hit or miss? I bet they never miss, huh?
got a boyfriend bet he Doesn’t kiss ya
I was starting to have withdrawal! Thanks for making yet another fantastic video!
I like the background music, it gives a nice relaxed feel to your already smooth work. Keep em coming johnny - Appreciation from Denmark
With some electronic and that electric motor/generator you could make a phone charger out of it. 10W is enough for a USB plug
awesome, i have a love for hit & miss motors
You should make a setup to use it to charge your mobile phone!
SamTheSuave not enough power
Sure there is, he's running a 10 watt bulb there. Smartphone chargers only draw around 6 watts.

Running much better, but take one governor spring off to slow the hit and miss right down.
Use LEDS to draw less load from the dynamo too.
Can you make a functional 4 stroke engine? That would be amazing

but he didnt made this one
I think he talks about SOHC or DOHC engine. that engine is much better than hit and miss engine.
Very difficult to construct, you need special types of metal and all sorts of different tooling
Derpin Bird yeah. I knew it. You must have special skills and special machines to make it.

Nice engine!!! u can get a more 'efficient' generator using a stepper motor from old printer. Only need a few diodes.
stick magnets to the flywheels and some coils on the base, scrap the motor/generator completely.

Actually this is an extremely cheap model... hand built models often go into the thousands.
Did more spring tension slow it down or less tension
what if you use gas with 2 storke oil it would lube the engine nice and it would last longer im guessing
weird question but is the screwdriver at 1:37 a powerfix? Ive got a set from lidl that looks the dame :D
It has batteries to fire the spark plug right... Could you use the generator to fire the spark plug and eliminate the need for batteries altogether?

Are you can make a automatic watercooling System make or Not???
Nice sound when the motor is under load.
Love all the projects you make. Keep on!
I’d probably set up to charge it’s own ignition system. Maybe strip apart a cheap portable charger for parts.
Does it fire only once now every hit?

you can also make it smoother by decreasing the compression

Beautiful device. Nice work as always.
would a nitro engine be powerful enough to help push a bicycle?

Hi can you get Chinese Stewart engine copies ?
I ordered one of these on april 4'than they said april 21 will be expidited shiping' still havent heard anything back from these people :/

is your channel name inspired from the johnny quest cartoon series?
I like this when it has a load
True master of your craft! thank you for sharing.
Just connect that motor to the spark plug on the engine and you won't need a battery anymore maybe
Uhh.. I don't think 5-10v will replace 50,000v ignition circuit
You can use the generator as starter
Lol to all the people saying LEDs LEDs!!! No the 10w bulb is more than enough to prove point.
thats a sweet engine !!
we had this in a bigger size to run grain mill when i was a kid just throw a belt on it and away you go
Sxedon ola ta ergaleia apo LIDL opos oloi mas.. ;) wraios!
hold on. is a normal generator like saying a motorhome basically a hit and miss engine? because it kind of sounds like one
CollinandMason No, not anymore. A modern generator uses a standard 4 stroke engine turning at a specific speed to produce 60Hz AC current.
I love your videos!
I think you need to add some LEDs instead of that bulb. Then you'll get some decent light output instead of that pathetic amount of light.
