Hello Guys,
It's time to build something really complicated.
This is kind of experimental video. I have a very old unrealized idea about an internal combustion engine, if be more correctly intake and exhaust system. Usually valves perform this function, in our case it is a camshaft with channels for passing gases.
Ideas can be very logical and interesting on paper, but in practice it is very difficult to prove.
So let's build a brand-new engine with never seen before intake and exhaust system and prove this idea. Whether it will work or not is a very big question. Let's find out.
If this engine works as planned, then it can be built into any car or even build some kind of all-terrain vehicle.
Friends,
As you have already noticed, I read almost all of your messages and am happy to share my ideas with you, and as far as possible, I listen to your opinion.
Share your opinion on this and leave comments.
With best regards
Meanwhile in the Garage

@ScatManAust 2 роки тому
Mate , you should cut piston ring grooves in the rotary valve ends and install wear sleeves in the head or completely sleeve the head and run piston rings to seal the head to valve . It may need two or three each side. But like people here have already said , recheck the ignition timing to make sure its correct. Use a timing light and a protractor to check the ignition timing , its very simple and it will remove any doubt. And its here I think the main problem lies. A simple engine like this will run on quite low compression as long as everything else is in parameters. Do a compression check and see , again it will give you a good idea. I've had simple engines like this run happily all day on 60 or so PSI. I remember as an apprentice 50 or so years ago an old Holden six cylinder ran like a top with only 70 PSI on all cylinders but I think the secret there was all six cylinders were all the same. Please don't give up on this engine, you have come too far to give up. The engine will probably never run anything useful but would be a good model to show and display. and be proud of. I love your work and I was transfixed to the monitor the whole time . Brilliant , just brilliant
@bluepriushere 2 роки тому
It's amazing. But... your cylinder head need an upgrade about the position of the spark plug. The geometry of the head is more important than anything else. Sorry for my bad English. Good luck : )
@henrique14211 2 роки тому
Exactly he needs sleeves, on both sides for head to valve , and probably two between side to side like apex seals from a rotary madza or something like that

Yes please try adding rings to each end of your rotary valve. Also one on a slant between the intake and the exhaust. Like a rotary engine seal.

Something very similar was done on a 5 litre Ford V-8 in early 2000's. It could rev to 10,000 rpm as it didn't have poppet valves .It didn't have any oil feed to top end either using carbon ceramic bearings which also acted as seals. A few years earlier I came up with something very similar as well but couldn't figure out how to make it work on more than a single cylinder (designed around a Honda 90 engine)
@lonniebryant8572 2 роки тому
I will give you an "E" for effort. The way it was shooting flames out the exhaust I will say it's in the timing, most likely between the valves and your design of intake. KEEP TRYING ! don't ever give up. Lots of luck to you my friend.

I also was thinking that timing is an issue. The timing, duration, and overlap could also be contributing to the low compression.

Sir, I really enjoyed watching this video. The amount of work and effort put into making this engine was truly inspiring. I was captivated during every minute. Even if the end result was an engine that didn’t run, the skills that went into machining parts and fitting them together was truly inspiring. I am a journeyman diesel mechanic by trade, so now I too am wondering why this engine didn’t run, and what could be done to fix it. (It’s literally in my nature) So I have a suggestion for you sir. The spacing between “valves” or intake and exhaust ports may be too close or even too big. It just might be that the engine is dumping it’s compression through the exhaust port too soon. One thing I’ve learned during my career working on engines is timing is everything. Your little engine wanted to run, but most likely couldn’t because it was forced to dump its compression before complete combustion could take place. Again, only a suggestion. Maybe a 2nd look at your invention is warranted ? I look forward to seeing it run !!! And am definitely going to subscribe in hopes you do revisit this idea in the future. Stay safe my friend. God Bless and good luck !

@ImmortanJoeCamel 2 роки тому
It's either valve or ignituion timing. At least it looks and sounds that way. Even with very little compression it should still be able to run with no load. I think it should run with some more adjustment. If you need a drill that big to turn it, it's probably not compression. It was absolutely amazing watching the whole process of the motor being built. Great work!
@markbooe205 2 роки тому
Yeah, even a small amount of compression it should turn over. I also agree the timing could be to far out.
@MrDanto2041 2 роки тому
Completely agree, also some oil porting of some sort or coating to reduce friction on the valve shaft will be something nice to look into.

This engine will work. Ignition needs to be advanced on low compression engines. I would try radiussing the flutes on cam. Possibly advancing cam to open intake before TDC. Keep playing with it and it will purr like a kitten...
@MadeInMichigan 2 роки тому
I was going to say exactly that. You can tell the timing isn't right because there's exhaust blowing out the carb. Like when he got sprayed in the eyes towards the end. Watch the mist coming out of the can of starter fluid. Plus, if compression is the issue, make a little bit longer rod. Or make/find/buy a new piston. Probably, it's easier to just make a rod for it.

Я тоже залип на этом видео и смотрел его без перекуров.

За один оборот коленвала все такты проходят только в двутактных двигателях и в роторно - поршневых, а в вашев двигателе я не увидел продувочных каналов. 2. вы крутили против часовой стрелкисвой двигатель, попробуйте покрутить свой двигатель в другую сторону, т.е. по часовой стрелке. 3. в системе зажигания на вашем моторе нет возможности регулировки угла опережения зажигания, искра должна быть не в верхней мертвой точке, а чуть раньше в.м.т. 4. передача от коленвала на вал фаз газораспределения должна быть 1:1, а у вас одна звездочка чуть больше другой, сделайте звездочки одинаковыми. Кроме этого, попробуйте немного сместить в.м.т. относительно вала фаз газораспределения в ту или другую сторону. Удачи вам в ваших экспериментах!

Золотниковая подача смеси давно применяется в ДВС-микродвигателях с этим не должно быть проблем. Выхлоп золотниковый - в теории тоже должен работать, возможно не отстроены фазы, либо выпуск и впуск пересекаются. Впуск желательно по площади раза в два больше выпуска. Но на счет долговечности такая схема явно будет уступать классической клапанной: золотник вращается в камере сгорания, изнашивая посадочное место из-за нагара, нагрева и отсутствия смазки. За культуру технической реализации лайк, однозначно

Чтобы деталь крутилась в детали, нужно иметь между ними зазор не менее 0.05 мм. Это не герметично для газов. Есть другой способ убрать этот зазор полностью. На одной детали нужно сделать канавку и утопить в неё на пружинке шторку, которая будет всегда притираться с движущимся валом, стенкой корпуса. Такая деталь уплотнения стоит в воздушных высокооборотистых шуруповертах, которые работают безотказно 20 000 часов (проверенно мною) и им хоть бы что. И сделать их можно не из металла, а высокотемпературного пластика, текстолита. Всего то делов, прострогать канавку и вставить на пружинке текстолит. Это будет герметичнее и надёжнее клапанов. С компрессией можно справиться. Другое дело нагар и его воздействие на стенки как абразив. Смазка движущихся частей, которые на сухую не должны работать. И это тоже легко решается, если перед компрессионной пластиной из текстолита поставить одно или два компрессионных пластины из твёрдого металла, как у обычных компрессионных колец, с дополнительной маслосъемный пластиной. Без них компрессию не создать. Но пластины на пружинке будут работать 100 лет в отличии от колец поршней, срок работы которых ограничен конструкцией поршня. Так что это очень хорошая идея, создать двигатель облегчённый, надёжный, без громоздкой ГРМ. Это двигатель будущего, для самолётов, планеров, ЛЛА, мотоциклов и машин. Продолжайте дорабатывать !

@@RealBlackFalcon Это элементарно Ватсон ! У поршневого кольца упругость колец падает в квадрате от выработке колец и стенок цилиндра и зазор в кольцах - основная потеря компрессии двигателя. Нагар под кольцами - основная причина выхода их из строя из за залипания. Какое бы качественное топливо не было использовано. От масла моторного ни куда не денешься. Упругость кольца ограничена её конструкцией, больше не сделать при всём желании. У шторок никакого зазора нет и не может быть, а усилие прижатия может регулироваться не ограничено, как механическим способом, пружиной и регулировочной пластиной, эксцентриком, так и пневматическим, гидравлическим способами. Множество вариантов. Всегда можно держать компрессию под контролем. Ресурс мотора напрямую зависит от выработки поршневой группы. Салфетка нужна для другого дела. Тесла (без салфетки) ни сделал ни одного письменного расчёта, а его изобретения до сих пор никто не повторил. Мотор Кавасаки сделан был чисто экспериментальным путём, по интуиции, и его двигатель считается не превзойдённым шедевром мирового моторостроения до сих пор.

I suggest 3 modifications: 1.about the compression issue use rotary seal on both side intake and exhaust between the pipe and body. 2. in IC Engine valve timing is very very important to run a engine. i suggest instead of a single pipe inlet/exhaust. make it seperate and then fasten it face to face, by that you can change inlet vs outlet angle(which is now fixed). also timing with respect to crank rotation can be managed by usual timing chain shift as we do in conventional ic engine. 3. you have to manage the spark timing, which can be managed by making the pick up coil adjustable. degree forward or backward. cause you know spark is not at TDC , you need to adjust that. i strongly believe you will definitely succeed in this. i am ready to volunteer help in this project to make it success. feel free to reply. i will clarify.

@MarvinLeeKeshall 9 місяців тому
If valve installing was made as a split head it would be possible to use sealing rings on valve tube. It would greatly improve sealing of combustion games and allow use of seals for tube lubrication. I know just boring holes for valve shafts seems direct but making top and bottom to assembly allows more control of overall sealing. Very similar to put to case halves together. Intake valving could also be improved by using a Reed valve to prevent back flow on poor sealing of rotating shaft as some clearance is needed to prevent shaft from grinding against housing. When thinking about my solution, thing of how multi cylinder. 2 strokes seal individual crankcase spaces to isolats each cyl.

@@papa58857 Ну Вам-то конечно виднее о плотности узла распредвал - головка, ведь вы принимали участие в проекте и сделали все необходимые замеры и расчёты... В случае плохого уплотнения этот двигатель должен постоянно "чихать" , при чём в обе стороны одновременно. Могу сказать лишь одно, что двигатель с обычной системой работает и с не притертыми, и с зажатыми клапанами. Не идеально конечно, но всё-же работает. И если всё дело в уплотнении, то человеку надо всего лишь проточить пазы под резиновые уплотнения - колечки, и убедиться в этом. Узел будет не вечным, но времени на выяснение причины хватит. И если всё-же причина в отвратительном уплотнении, то можно подумать об реализации уплотнения, использующегося в роторных двигателях.

Rotary valve engines have been around for a long time, well over 100 years. They always come up against the same two problems, lubrication of the mating rotary surfaces and sealing. Nobody, even very experienced developers like Cosworth have been able to solve these issues. The nearest solution was sleeve valves as used in the Napier Sabre and Bristol Centaurus and Hercules engines. However if you watch a video of one of these engines starting, you will immediately see the problem in today's pollution conscious world. A Bristol Centaurus when starting, can cover a whole airport with burnt oil smoke.

It doesn’t SOUND like a compression issue to me. I’ve seen old engines that had 30psi compression (I consider 90psi and less to be low on most engines) fire right up and ring great. Sounds to me like timing. Try advancing your ignition timing a little, maybe slowing it. If that doesn’t work try messing with the rotary valve timing a little. You’re definitely on to something though. Considering that it’s a 65mm (or whatever it was) bore that looks to be fair compression.

It almost started several times, I do believe the problem is that you needed a way to adjust your coil around the flywheel so you can advance or retard the spark timing in reference to top dead center (TDC) of the piston, that would allow for easier start-up of the motor. Most engines fire at 8 deg. Before TDC, but if you could adjust your coil position it will change your TDC firing position.

The timing maybe off from diameter to diameter. Top gear maybe to small for rotation which caused the fire to come out on the fuel side. Cam oil feed also needs to be covered (This is causing your Compression getting force down the oil feed past the pump to the sump.) With a monel sleeve bearing of 5 thousands oil clearance with only 3 tiny holes 2 at each end and 1 in the center and 1 return on the opposite side will solve this problem. Plus note steel and aluminum tend to stick when they get hot cause steel expands faster while the aluminum which loses it's heat faster does not. There for always grabbing when you turn the engine for to long. Also the cylinder needs to be honed to hold oil and your missing the oil pick up on the crank that splashes oil up into the cylinder.🤔👍

Привет, очень хорошее видео. Как вариант чтобы увеличить компрессию нужно проточить на поршне ещё одну канавку для третьего компрессионного кольца, так же в место где вращается вал сделать проточку для сальника. Ещё можно применить другой вид топлива например: 1 часть эфира + 1 часть керосина+ 1 часть касторового масла.Такой вид топлива можно использовать для авиационных моделей,этот вид топлива можно использовать без свечей зажигания. Ещё один способ для увеличения компрессии - можно сделать регулируемую камеру сгорания путем затяжки сверху болта( это второй поршень который находится в верхней мёртвой точке и регулировочный болт давит на этот поршень) Так происходит регулировка камеры сгорания. По отношению к валу для впуска и выпуска: окно для выпуска должно быть немного больше чем для впуска - за счёт этого улучшается продувка камеры сгорания , тем самым улучшается коэффициент полезного действия. Если интересно то я ещё могу много рассказать про это. Удачи.!

Плохая компрессия здесь как раз из-за системы впуска-выпуска. Соединение распределительный вал - головка не обеспечивает достаточной герметичности. Эфир с керосином и касторкой здесь не помогут так как не обеспечена достаточная герметичность камеры сгорания и невозможно добиться необходимого давления и соответственно температуры для вспышки такого топлива.
