[@jackansi]

That spin comes from the spring, yes. When you compress a coil spring a tiny amount of torque is created. If the resistance to this torque is different between loading and unloading of the spring, and not otherwise prevented through friction, it will cause a rotation.

[@jgerdinggmail]

It's a nice side benefit because it evens out the wear also

[@TrentTationnaiseXization]

Well said.

[@OrganicGreens]

Just the comment I was looking for. Thanks

[@vsvnrg3263]

jackANSI, that sounds right in this instance. compare the action of a spring washer. about 30 years ago mercedes (i've seen that he drives one) boasted that the valve gear on its new engines rotated to even out wear. wow, how clever are these germans! hey, hang on. i've since found out that offsetting the valve gear from the actuator is a very old trick that may go back 100 years. in fact, all engines i have owned have incorporated this turning business into the valve gear.

[@bobblaine1437]

@@vsvnrg3263 Positive valve rotation was introduced in the '70's when leaded fuel was introduced on most cars sold in the US. If you don't rotate the valves, they will wear into the valve seats in the head and eventually the engine will lose compression (prior to that the lead in the fuel lubricated the valve seats). The rotation force typically comes from the valve spring retainer that's designed to create that force every time it's compressed and released. In automotive engines the contact point between the tappet and the rocker is also offset to encourage the rotation.

[@George19532009]

Sir, my theory is that the rotation of the valve cups is caused by the natural vibration of the engine in the same manner as a bolt will screw or unscrew setting close to a source of vibration and thus lock tight is needed. A paper towel rack standing upright setting next to a spinning washing machine will do exactly the same thing. To prevent that paper towel from unrolling all it's paper, you put it on the holder facing in the opposite direction. It doesn't stop it from rotating, it stops it from un rolling. People driving motor homes can also appreciate that with paper towel holders as well as toilet paper holders. In this case, it is probably a good thing because it doesn't have one specific spot where the rocker arms constantly touch like rotating the tires on a car makes the tires wear longer and give better service. AS the pressure of the rocker is released, the cup has opportunity to free spin like a Solid lifter in a Chevy high performance engine. There has to be a little tolerance so that lifter can move to prevent seizing and sir your observation in study on this little engine is as curious as my own LOL, I just bought one, just ordered the 2 speed clutch, not sure if the rpm will allow much of a shift but I also have a two speed adjustable transmission and this engine screams "RAT ROD". The learning lesson for me on your video is that no matter how close the tolerances there has to be some space to move and there will always be a vibration no matter how well balanced it is, if it is running. I also have studied and have learned that is some specific cases like this, that vibration is a good thing for certain "Specific" parts of an engine where this vibration in other parts of the engine will cause it to come apart. It's the perfect learning tool. Thank you for taking your time and expertise in video to show this in a manner it can be seen "In Action"!

Time for a durability test, how long will it survive full throttle operation and what fails first...

[@revtech2917]

Only meant to be ran for a few seconds at full throttle. Its still running on 2 stroke fuel so the internals don't get lubricated like a real 4 stroke with an oil pump. At full throttle It would probably only last a minute or two before it destroyed the sleeve/rings.

It might have to do with it being a four stroke design on 2 stroke fuel but I feel like it wouldn't make much of a difference because it's still the same except valve but idk maybe!

The valve bucket spin seems like a critical component to the long term use of an engine that relies on them. Without spin, you would likely get dishing where the rocker hits it. With spin, you get a nice even wear pattern.

[@WarpedYT]

Agree 100%

[@drewanderson8279]

I was suprised to see on other motors that the push rods also spin. And I saw a video where junkyard digs showed that a couple cylinders had issues and he showed where the push rods were not spinning. I just watch a video of the brass engine from China that blew up with oxygen and Acetylene. The push rods on that motor were outside the engine. Now if u look at the slow motion u can see the push rods actually rotating as well. Pretty cool little thing I noticed!

4:50: The exhaust side components have to handle much more heat than the intake side components. Take the intake valve, for example. The intake valve's temperature gets up only to one hundred degrees F because it is constantly getting cooled by the incoming air-gas mixture. But the exhaust valve's temperature gets up to 1200 degrees because it takes the full brunt of the outgoing burnt gasses from the cylinder.

[@codyhubert6178]

As far as the valve spin, it is absolutely due to the spring geometry. Any helical spring will compress linearly as well as axially. For valves designed to be able to have freedom to rotate around their center axis, they will spin with this movement. I am not an engineer, but here's my take: I am not sure if they did this on purpose, but in my mind it would enable the valves to last much longer without changing dimensions due to wear spreading evenly AND (this is more important) allowing the contact portions of the valve stem to be lubricated more effectively. Tiny little engine so I doubt they put this much thought into it, but it's a really good idea and I'm starting to wonder if real vehicle engines do this too. Awesome observation! I've never seen this before and I'm super interested!

[@Melo3dewz]

The spring compressing and returning makes the bucket spin... It helps reduce wear so the rocker doesn't gnaw in one spot

[@mChav34]

that was cool. I theorize the buckets are spinning because of the lip of the cut coil on the end of the spring grabbing when the spring expands. or just standard spring rapid expansion/compression behavior

[@harriel001]

The valve buckets spinning is probably a designed feature and not just a coincidence. If they didn't spin the rocker arms would end up wearing a groove in the buckets, the spinning means they're not hitting the same surface all the time so they'll wear evenly across the surface of the bucket. Probably not super important for a hobby/demo engine, but extremely important for extending the life of an engine that's going to see tens or hundreds of thousands of hours of work.

[@jerrypeppler1484]

I thought the spinning deal was intentional also. What is done in the manufacturing process to cause the spin?

[@a3c1m]

Cut coil in glow plud and it make it into spark plug, by spark generator for spark plug (don't know exact name, but it comes as a kit with sensor) and connect it, run it with 2stroke gas fuel mix, it will shoot flames, get the idea right. It will be not hard to do.

[@davidkulm6795]

What you have is essentially a diesel engine (no spark plug, distributor, or ignition system), where combustion is based on air-fuel mixture, heat & pressure. In this case, when the cylinder gets sufficient pressure, the hot air-fuel will spontaneously combust igniting all the fuel at the same instant. The only way that I can see to get flame exiting the exhaust port would be to get more fuel into the cylinder and or get the exhaust valve to open slightly earlier in the timing cycle, in other words, get the exhaust valve to open while the fuel is still igniting. Maybe try some Nitrous Oxide.

[@srmoll]

I'll bet the bucket spin is caused by the spring. When a coil spring is compressed the ends of the spring will rotate slightly in relation to each other. When the rocker arm presses down on the tappet (bucket) it is prevented from turning by the friction between the top of the spring and the bottom of the tappet. When the rocker arm releases the pressure to allow the valve to close, the spring can now perform its small rotational displacement, which imparts a small kick to the tappet which causes it to spin.

[@sharknado7157]

Sand 0.5 mm to the cams rounded surface (not the bulky one), looking at the shaft that´s all you probably have, if not less. Supplement the shim , or the inside of the buckets with a chip of sheetmetal (same thickness mentioned) to adjust clearance. Basically you´ll increase the cam lift ratio. Sand 0.25/0.3 mm off the top of the sleeve to increase compresion. We´ll get closer to fire.

[@lomasck]

I can tell you where the spin is coming from. The spring as you suggested. To stop it rotating you need 2 springs. One inside the other with a opposite bend. On the way down the valve is rotating the opposite direction .when closing the valve will rotate the same way as the caps.The cap can only rotate once the cam has backed off. Compress a spring & you will see it rotate depending on the angle of the springs & direction of its bend. This is how a valve can where away its seat if you use LPG or instead of leaded Gasoline. Cams are cut on a angle to & placed offset to even out wear. Its not wanted on the valve though.

[@cravenmoorehead5636]

Yes it is wanted on the valve because it prevents carbon build up from causing the valve not to seat correctly.
