I totally agree with you. The "v8 sound" should be called the "crossplane crank" sound as that's what it really is. When you hear a v8 with a flatplane crank it sounds just like an inline four with a flatplane crank (ie: dull;). Hardly anyone seems to see this.

+Aliaksei Zholner Thanks a lot..

It is hard to say why your model is not working. Actually no one of my models work from the first time for me too - it is paper :) Also the plans are not ideal, I'm not a professional in it. The only thing that I can advice without seeing actual model - try to ensure that the friction is minimal - it should move very smooth

Yes, each crank in the crankshaft is shifted by 90 degree from previous

Does the air go through the gap of the pistons and cylinders?

correct

I was thinking of using graphite to lubricate the cylinders and bearings, to reduce friction, will it work?

It's hard to say without trying; but if you'll use my templates, please note that the gap between piston and cylinder is already quite small (about 0.5mm), so if you plan to add additional graphite surface, you maybe will want to increase the gap either by reducing piston or by increasing cylinder diameter

+Mr. Fai da te , for this engine I used mostly PVA(polivinilacetate), but for further models I decided to use superglue (cyanoacrylate), because it is "faster", and it is not water-based, wich is better for paper work

+Aliaksei Zholner I'm stuck with number 37 , I can't seem to find out what it is for

+Aliaksei Zholner also please make a clearer picture of how to make the paper engine please

but you know that to open these files you have to download the whole thing? I had that too, but I used my brain

Через зазор между цилиндром и поршнем

@@nothingssmore Понял, спасибо.

David Majtner glad to hear, now make and share video with you model :)

I make holes with a modelling knife at most, but sometimes I use punchers of an appropriate diameter. As for the paper with superglue instead of cardboard - yes, I guess it will work, if the sickness will be the same(or at least similar)

​@@nothingssmoreis the part 32 glued to the chassis or the rod? do i need to cut a hole in the middle of part 18? is 19 glued to part 19? are shaft E and D set to 90 degrees? do you thickens the office paper?

Office paper, watman, cardboard

It is hard to say. Maybe yes, with all parts made of cardboard and reinforced with something like superglue

Aliaksei Zholner thanks for the reply. I'm planning on 3D printing it so I don't think the part strength would be a very big problem. I've 3D printed the parts for an air engine before and it works well with some metal parts and ball bearings for the crankshaft. I'm just concerned that the valves would start to be held down so hard by the air pressure that they would cause a lot of resistance to opening and then make the engine run worse at higher pressure

I hope this picture can help drive.google.com/open?id=0B0xqQIZvwhdiZ3lQZUIwaTRWYzg

+Aliaksei Zholner Hi thanks sorry to worry u again the piston connecting rod how did you cut it mine keeps breaking at the tip when cutting

is the part 32 glued to the chassis or the rod? - to the chassis, it is kind of "stand" for the camshaft do i need to cut a hole in the middle of part 18? - no is 19 glued to part 19? - no, it should only be bent by dashed lines in different directions, to form a spring do you thickens the office paper? - no, first two pages of templates should be print on wathman (with density 120-180 g/m2), and there are tips which materials should be used for parts on the third page

@@nothingssmore ty, this is why I supported people like you so much even though the video was 13 years ago :D

I think yes

a set of valves are opened by camshaft driven by the crankshaft, and these valves let compressed air to go to cylinders in appropriate time moments

different types, for example, printer paper (80g/m2), watman, cardboard

@@nothingssmore Um its the paper you use for that inline 4 is 160g?

+TalonRochefort , yes, there should be 32 parts of piece #37, and each knee of crankshaft requires 2 details each of which contains 4 parts of piece #37

I am working on a tutorial right now, I'm almost finished making my first 4cyl, But still refining manfacturing techniques, Should have a tutorial up in about 2 weeks.

kzfaq.info/get/bejne/f8-CYNqi2Ni5aGg.html Here's an intro, I built the engine, badly but still did it. And the tutorials will be geared toward learning by trial and error, and refining techniques on how to manufacture the parts consistently and in a timely fashion. This video is just explaining the troubles I had with the build and just me rambling on about how I'm going to take on the challenge of building this motor with no experience.

+Joao magalhães , unfortunately I have no detailed photos, but I hope this picture can help: drive.google.com/file/d/0B0xqQIZvwhdiZ3lQZUIwaTRWYzg/view?usp=sharing

+derek scott , it is just regular office paper, I've just rolled it very tightly until there are no gap in the middle of rolled tube

Okay thank you! Might take a couple of tries

it works using principle of pneumatic engine

+CYLON659 Exhausted gas goes througs little gaps between pistons and cylinders, because they are not 100% fit in diameters, and there are no any sealing piston rings

+Aliaksei Zholner thanks for the reply

Nothing, its just a model.

Кое-что снимал: kzfaq.info/get/bejne/i6-bZ9SAs92UoqM.html , но в целом чтобы снять качественное видео построения модели у меня пока не хватает способностей и времени )

понятно,жаль конечно(( а вообще я узнал про тебя из газеты русской в германии, газета МК, там про орган твой рассказывали

Zigzag paper is spring that should press on tappet for tighter valve closing, but I think that it would work even without springs. Anyway, nice to hear that you built your model, try to connect it to more powerful air source, for example to compressor ) and upload video

LastManFarting , I would say that if you'll be able to create internal combustion engine made from paper, it will work fast, but not very long ;)

Al Zh Nice. not sure if it would be efficient, but that is not my no 1 priority

+LastManFarting he means the paper would start to burn.

+LastManFarting In what world would you be able to use combustion for a paper engine?? Pretty stupid question....

Sp i don't know :D LOL, i was talking about hard paper soaked in super glue, it's heat resistant, some guy made a gun out of it.

+Андрей Анашкин, "выхлоп" выходит через зазоры между поршнями и цилиндрами, т.к. они не совсем плотно подогнаны

+Manoel Luis If you mean put it in car not only for decoration but as a real engine, I would say no, because it have too little power, and also it's necessary to have very powerful and lightweight source of compressed gas

You could use dry ice, love to see some video's on that!

в описании

@@nothingssmore Спасибо большое, ещё вопрос, есть ли туториул как собрать?

только то что в описанни

+Mr. Fai da te , oh, sorry, seems there are two details with #17 in PDF. Detail #17 from the first page in pdf together with 25, 33 and 40 - it is valve. And details 17, 18, 19, 20 - it is spring(19) inside body (20) wiсh pushes the valve using details 17 and 18

+Mr. Fai da te, for this model I used whatman paper and cardboard

Filter paper?

+Mr. Fai da te , not sure, I believe it was dense paper, about 200 g/m2

+Aliaksei Zholner I search whatman paper on google and found the filter paper

LastManFarting , I think so. I've built V6 paper engine kzfaq.info/get/bejne/nLqPm7d50Zrbh58.html . V8 is harder to build, but I think still possible

+Kevin Guillen De La Guardia I don't use whatsapp, but I have just checked link from description and was able to download without issues

you can find a photos of building process in pdf file in video description, or maybe you have any specific question on building process?
