I was thinking that what will happen if we arrange inlet & exhaust valves on the piston (spark plug remaining on cylinder head)? i think that may be by using metal foam on the cylinder head the knocking of the engine might decrease. please assume that somehow i use proper mechanisms for valve timing & they dont have any appreciable effect on the piston. just consider that the weight of the valves is added to the piston. i was wondering that this might increase the efficiency of the engine because suction will take place more slowly (so it will near a reversible process, so efficiency will increase) & force of the explosion will be better. please you ppl; if anybody can give me satisfactorily explanatory answers, do reply! :)

I've just got hold of a rail section car with the above engine fitted. It had not been used for a couple of years but we managed eventually and started playing. The problem I have is it travells in one direction well but in the other direction it 's hard to start and looses power. It also over heats  I would say it has something to do with the mag and timing. Can someone please help.

I am investigating th' lost foam casting technique and one of th' problems is th' surface texture of carved foam ! I know that large scale mfg's of cast alloy parts make foam patterns by injecting foam into a permanant (female) mold and then use th' foam pattern to cast th' part !  This gives th' cast part a very fine finished surface with no need of  machineing (except for fitting to another component ) I'd like to know how they create and manage th' foam !

Hey! i want to built a gas jet engine without the turbocharger! can u help me with combustion chamber and inside shaft ! and one more question! how to convert the power of a jet engine in speed!?

Can anyone recommend some CAD or CAE software for mac, I love mac dearly but i need some engineering software. 

I want to design new propulsion systems that don't need to use combustion, what should I major in, I was thinking of majoring  in Aerospace engineering and minoring in Electrical engineering. Any suggestions? p.s. the propulsion includes, but is not limited to: anti-gravity/warp-drives  (Which physics says is plausible)

This is just my burning question for anyone who has mad skills in engineering. how do I build a small stirling engine generator for home use to run off a non-combustion heat source ie solar panels?

I was wondering if instructable authority could a chat engine to instructable. I m saying that because many of us are in need of help what we do through updating posts. So, if there is a engine we can get the solution right on the spot. Rest of is up to the authority..

Hi, My names Tom and I need a team of experienced engineers, biomedical engineers and programmers to try and design different biomedical devices. This will be a NON profitable team, so it would be more of a hobby than a job. But I will take anyone that thinks they will be helpful. Get back to me soon if your interested please, this would also be a great idea for students at universities or collages that want more experience. Thanks Tom

Would connecting like 2 or more single cylender horizontal engines like briggs and strattons together flywheel to shaft run as like a 2 cylender in line engine? or has anyone done it even? example : if      [0-     represents an engine with the [ being the flywheel, the 0 the crankcase/block and the - a shaft then this is my idea [0-[0-[0-  and so on like a two cylinder would be [0-[0- would this work? what would i have to do to get this to work?

Um yeah just like that guys picture but without the weird background or the guy on the board

Hi everybody im still new and don't know anything about knex but i loved the idea of making engines is there any special kits to innovate new engines and make something new , is there any calculations?? can anybody help me by giving me information websies abou knex for beginners especially for engines. can a knex engine work with compressed air or just with attaching the drive train with an electric motor is it easy to make and is it good idea for prototyping you ideas?? thanks i know that i asked too much questions (im still beginner) and i know that the instuctables knex PROS will be helpful with me PS ,can anybody tell me where can i get a good price buy for a knex kit that contain everything for my infinity innovation

I am planning on making a very high volume compressor from a small engine.  I plan to adjust timing and stuff accordingly.  I just wan't to make sure an engine can handle the pressure.  I assume it can because of the explosions it can contain but I just want to be sure it can handle 125-200psi.  And also, is 2 stage really necessary or can I just push all the air in in one stage with a couple pistons.

The web guys should write a search feature that counts the number of times a word or phrase is searched and then displays that value whenever that same word or phrase is searched. A separate page containing the top searched words or phrases could be added. A feature such as this would allow members to create instructables about topics in demand.

I am wanting to make a small solar steam engine and am wondering what pressures they run off of usualy? Can you power a pneumatic drill or grinder with steam and use it as a steam turbine? How do people make small boilers to power the steam engines? I was thinking a peice of copper, iron, or galvanized pipe. I would heat it with a fresnel lens from a rear projection tv. Can the spot from a fresnel lens me further focused with a normal glass magnification glass?

I have a 4.3l v6 that came out of a s-10 pickup.  I was wondering if i could make it run on the stirling cycle? It is a 90 degree v6 so it should work, This is the only site i could think of to post this question on. I was thinking i would isolate the waterjackets to the right and left bank of cylinders then heat one side and cool the other. I am good with engines and am skilled in the garage. I'm just tinkering. Maybe run a generator with it if it runs. I have a welder, plasma cutter, ect and can use them. Just kinda throwin it out there...

I don't know if anyone else has had this "problem," but the site search doesn't exactly provide the best of help.  When I search the site for something, It'll often return 'ibles, forum discussions and other things as unrelated to my search as possible.  After browsing or going down the search results a way, sometimes I'll find an 'ible with almost my exact search term in the title.  IMO, something that should be at the top of the search results.

Hi everyone, I'm new here to this forum site but I wanted to share an idea I've been kicking around for a while now.  I'm a huge fan of the Fantasy vs Science Fiction debate and often like to combine certain elements from each into one another (ie Spell Casting Robots, Steampunk Wizards, etc). One of the staple elements of any Fantasy work is the iconic Wizard's Duel, when two magical wielders face off against one another using a combination or various spells, attacks and magic.   Now, I've always been interested in the kinds of sports/ competitions that focus scientific and engineering minds (robot battles). So I devised one of my own today, just something I think would be really interesting to watch. It's sort of like a modern day resurrection of medieval duels, but instead of weapons the duelers use inventions. Engineer's Duel Overview: Two inventors face off, each utilizing different inventions they've built to best their opponent, and eventually destroy them (or at least incapacitate). The purpose of the battle is to test the wits, intelligence, strategy and inventing skills of each of the duelers.   The goal is not to destroy the opponent, but instead their chosen gadgets until yours is the last one surviving. Rules: 1) No Robots. This fight should be between the duelers themselves, not their robotic minions. 2) No Direct Weapons Allowed (devices that serve no other purpose except as a weapon). Eg no guns, swords, canons, etc. The purpose of the duel is not about how powerful an invention one can build, but how inventive it is and how well the dueler uses it. 3) Each invention chosen by the duelers must be used at least once in the fight. 4) No EMPs, for obvious reasons 5) Vehicular machines such as Tumblers, Mech Warriors, and Giant Hovercrafts are allowed but only in the National Primaries. Other than this, if you can build it, you can use it. So yeah tell me what you think!

I am hoping to find a way to increase the compression of a small.18 radio control engine. I was wondering if applying high temperature epoxy would work because it will go on the sleeve rubbing against the piston or holding aluminum foil with the epoxy. 

Grandson is 7 and loves steam trains I would like to have instructions on how to build simple small one that works

I have seen and checked several Instructables on Turbine Jet engine and I am trying to make my own,On a Turbine Jet Engine intake and compression fans ,are they connected directly to the axis ( Shaft )or they just revolve about it separately ? also please any info's about the fan's angle for each one, are they the same or opposite one another.?? Many Thanks in Advance

I am planning to build a jet engine . i want it to be safe and powerfull  ... please do help me in suggesting a method!!!!!!!!!!!!!

Ok I decided to rip into my tractor today because I was bored. I knew if I ripped into the actual cylinder that it would probably look pretty horrible with the way I drive my tractor. Needless to say I was right... I want someone to tell me what I can do with this!! I have it sitting open like it is in the pictures right now and I don't wanna put it back together until someone looks at it!. Also, how do I check that the valves are working right? Can someone PLEASE look at this asap?? Also does anyone know what I could clean the cylinder top and the cover with?? Would varsol paint thinner be a bad idea because of the gasket??

You have nothing on using bi-colored, 3 lead or 2 lead, leds.  Is this because you don't have any info or your search engine is lacking? To me a search engine should search for the item your looking for with the request "ONLY".  For example, if I'm looking for info or projects and am looking for "bi-colored led", then the first thing I should see is something with both "bi-color" and "LED".  Makes sense, then you can do your search for either "bi-color" or "LED".  Instead, I get LED projects, how to use leds, untangling rgb leds etc.  So, I love your place and the information, but  I don't really want to see every word on the planet with an l, e or d in it when I want one item to start, led.  I'm not software literate enough to write it myself, but I'm sure you guys are smart enough or know people who are. This simple idea could revolutionize search engines! Thanks for listening, Dave Mitchell

Help me any body plezz

I am looking to find small 2 stroke engines for cheap/free. I am not sure where to look. The side of the road, craigslist,and ebay have been of no help to me. I need something between 40-50cc and would like some god places to look. Thanks guys!

More spacific what kind of injectors do i use? I have a 61mm turbo out of a 6.5 cummunins. It's a VGR turbo. Any way, i am a welder, pipe to be spicific. and i know i could build one with just a little help.! And mt kids think this is really cool as so do i. So your help would be greatly appreciated.

Well can I? Like engines and stuff and  motorcycles.

I have a 2006 Mini Baja Minibike(http://www.bajamotorsports.com/categories/minibikes/products/WR65_baja-warrior-mini-bike) with more than a few problems. As of now, it won't even start, and I can't find the problem. I've cleaned anywhere that fuel goes, air filter, exhaust, and adjusted the carb,  it still doesn't start. When it was running, it didn't even idle. So I'm wondering, would an engine swap with this: http://www.harborfreight.com/engines-generators/gas-engines/212-cc-ohv-horizontal-shaft-gas-engine-epa-69730.html engine work? It seems almost identical; but I"m not sure.

If the intake turbines' speed is regulated by the compressed exhaust over the rear turbines, would it be more effecent to have 2 props in a row, or a single large one at the rear of the engine to control the rotation speed?

How can I make a jet engine that is realy tiny? I heard about this so called pen jet, can someone make an instructable, if there is one like that,? Or can you tell me how to make something tiny?
