Great job! On two 4 stroke engines, you could have timed the pistons, so they are both in tdc at the same time, and one fires and the other is in between exhaust and intake stroke, then the next time they are in tdc, the other will fire and opposite. Right now it is an oddfire engine, where you have uneven gaps between the fires - but I like it! :-)

Would that vibrate more than having them balance each other? Genuine question, i really dont know

@christiantrab6160 7 ай бұрын

@@platyperrin Good question, I don´t know really. But I have been tinkering with motorcycles many years, I know that a lot of the 2 cylinders are twin as they are called, where the pistons move side by side, so that the combustion strokes are one hole rotation from each other to make them run smooth. Anyway, it works :-)

When I was 14 a younger friend asked me to show him how to rebuild a small engine. So we got 2 Briggs and Stratton 3hp engines and pulled them apart. He did one, and I did the other. We did not bore them, just new piston rings, gaskets, spark plugs and cleaned everything up real nice. When done they both ran. Then I had 2 little 3hp engines that I didn't know what to do with. I had a Go-Kart, but it had a 5hp Briggs on it, so 1 puny 3hp did not interest me. Then I thought about combining them. I pulled the cranks back out and took them to school and in machine shop I threaded the outside of the pilot shaft for the recoil on one and inside the pto end on the other so the two crankshafts screwed together. I made up a common manifold and braised them together with something like Fonson or Phonson. ( I can't remember what it was, but it was not braising rod) When I got all done it worked and I really enjoyed the sound of a 2 cylinder engine on my Go-Kart. But, I got a lot of criticism for not timing the pistons. I had simply screwed the two engines together and wherever they were when it got tight was it. Some said the timing should have been so close that one coil could fire both for the most hp. Some said the two fought each other and it made far less than one by itself. Well, I had ridden my Go-Kart with a 5hp Briggs on it plenty, so I knew how much power that had, and I could dispel their criticism because my 2 engine Go-Kart had a lot more power than that single 5hp did. What do they say about proof is in the pudding? I had a lot of pudding time with my 5hp and this double engine had a lot more pudding. Also Too, I wonder: Did the engine in this video sound like an old John Deere B engine? I had a 2 cylinder engine on a two wheel walk behind tractor called a Standard Twin. BOTH PISTONS WENT UP AND DOWN AT THE SAME TIME TOGETHER. They fired alternately. It sounded perfect. I have had engineers tell me it couldn't have or it would vibrate itself apart. Well, somebody forgot to tell The Standard Engine Company of Minneapolis Minn. or just never bothered. Because they made a lot of them from the1930's to the 1950's and they didn't vibrate at all when running. John Deere I have read thought it would be too hard to balance their 2 cylinder engine if they had both pistons going up and down together at the same time firing alternately, so they did like the guy in this video. With the John Deere one piston fired at TDC while the other piston was at BDC so there were two power pulses 90°apart, then a long lag of 630°? ( something like that, do the math I may not have it right) until the first one hit again. What we hear at idle speed is the 1st one, it has to bring the engine speed back up from the long lag and pumping losses, and that makes the 2nd one inferior in sound, which is where they got the name "Johnny Popper.' Until the engine worked hard enough to have both power pulses working hard, to me, the John Deere B always sounded like it was misfiring. Hey, that was a long time ago and I'm gettin a headache from trying to remember it. ben/ michigan

I would try two carburetters instead and you need to adjust them 100% precisely. I don't know where to get it, but many many years ago I tried to adjust doubble caburators using a vaccum measuring system, on Audi 80, on the fly on a highway, we meassured the vaccum at 120km/h because they didnt work even at that speed.. In short terms we drove 120Kmh, notiched the vaccum differiencies and stopped at nexe haigway exit, adjusted, drove again.. VERY interresting how a very small difference, could give a huge result in engine performance. We adjusted the nozzels with very small round metal files. If the engines are not running at 100% precise torch, one engine will have to use power to turn the other. It's difficult to explain, but if you think about it it actually logical, IF you use a single caburetter, the distance to each cylinder must be 100% the same, polish the tubes on the inside as mush as you can, and the same goes for the exhaust system ( maybe two exhaust systems are better?) if not same lenght, one cylinder will sort of block the other cylinders outlet a little. Finally you could try to adjust the angle between them, eventually 45 degrees, and adjust the crank so it "kooks" like a Harley? just for fun :)... or buy a 400cc engine instead hahaha

@mazdamaniac4643 8 ай бұрын

Spark plugs with multiple electrodes doesn't make more spark, it forces the ignition coil to work harder than it should because it's trying to drive two spark 'plugs' from one coil output. You end up with either multiple weak sparks per plug, or the spark becomes unstable and ignores one electrode completely at random. Just use single plugs for a strong consistent spark. You may also want to think about timing the crankshafts so they work together, therefore each engine fires 360-degrees apart. It'll smooth out the fueling through the carburettor. That'll result in more consistent firing, less vibration from a more balanced power delivery, smoother overall torque...all of which is ultimately more reliable and lasting fun.

Fun project! An elastomeric shaft coupler might make life a little easier on the engines as it dampens the impulses a bit.

You should convert this to a draw through HCCI style engine, and use water injection just before the intake port where each case pulses it's own or each other's fuel pulse pumps, you may want to make sure the pumps will handle methanol or ethanol. Now you could use a butterfly as a throttle, and set it up to inject a small ethanol (vodka, 40% ethanol) boost each cycle. Homogenous charge carburetor runs better for a twin cyl than your carb, and the ethanol aka vodka injection system helps keep the engine clean, keep from overheating, and allows it to run very lean with less risk of issues, which is the main issue with HCCI carburetion. Could boost your low end torque and horse power higher, certainly will boost fuel economy.
