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! :)

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..

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?

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

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'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 !

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. 

Now this is a collaboration.

Hey guys, currently just a hypothetical but wandering what issues i would be likely to encounter dropping the engine of an impreza wrx into a 93 brumby ? also thinking of the transmition?

I have a Lionel 2046 engine  It has three windows. It is Heat Stamped on one side and Rubber Stamped on the other side. Does anyone have any idea what year this engine was manufactured? Thank you.

How come i cant find an instructables search engine that searches an instructables database?? I would certainly use this site alot more, as it is, I dont know If im going to resubscribe. C'on Instructables!!!!

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.

I need to ID a Wisconsin engine because I want to get some info and work done on it, but the plate on the front of the shroud with the info is almost un-readable.  Is there another way I could ID it?  I have some info I pulled off of it, check the pictures. Thanks

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?

   Hello Instructables community.    I was thinking of making a 12 volt battery charger with a trimmer engine (pictured) connected to a scraped car alternator (I found several on eBay). But I have a few questions: 1. Would such a combination work as shown in the illustration?  2. Would it be best if I directly connected the engine to the alternator with no drive belts or chains, or would the high gear of the large engine gear and small generator gear be worth the extra trouble.  3. What is the best way to connect the two? And 4. Where should I remove the engine from the "trimming part". Any answers will be appreciated.                                                                                                                       Sincerely                                                                                                                  Confused DIYer

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?

While expirimenting in my back yard i came across somthing. I was working on my steam engine and was testing the boiler with methyl alcohol as the heat source( i used nitro car fuel 20%) and i wondered what would happen if i put the alcohol in the boiler. I heated the boiler at the same temperature as i normaly heat water and the alcohol seemed to produce alot more vapors at a faster rate and volume than just steam. So... I was wondering if it was possible to create an engine on the same basic design as a steam engine that ran on alcohol expansion. I do not realy plan on creating this i was just wondering if it would work as good or better than steam. If someone has already made this please tell me. Thanks

 Babbage never got a chance to build his difference engine. Ironically it is considered one of the most advanced and is arguably the most famous of these old mechanical computers. One was eventually made in 1991  for the Science Museum in London. Don't live in London? Too far to drive? Well, no worries, Andrew Carol has built a working difference engine from LEGO's and with a kind donation of server space from Steve Wozniak, he's posted a very detailed explanation of his project so you can build one too! acarol.woz.org/

 How can you make a simple rocket fuel with only materials that you could get from your local hardware store.

Hi Guys Can anyone please help me. I have recently purchased a few parts for a jet engine off ebay as a possible project but can't find what engine they may have came off.  The combustion chamber is different to what you see in smaller rc jet engine. The turbine wheel blades are dove tailed like on bigger jets and the compressor wheel has an inducer of around 95mm. I would imagine if this could ever run again it would produce a serious amount of thrust. I have uploaded some photos and would be grateful of any help.  

I have been building a mini Jet Engine.  I have a VERY STRONG electric fan for the compressor.  Outer shell is made of sheet metal.  The fuel I have been trying to use is gasoline.  The intake is about 2.5 inches across and about 3 inches in it begins to close up to about 0.6 inch diameter where the air is compressed and mixed with fuel before being burnt.  The problem is that its starts but it explodes.  Is it too much fuel, to much compression from the compressor, to small of a diameter for the combustion chamber and exhaust or something else completely?  Haven't done much with jet before so any help would be appreciated. Thanks

I want to go to a good electrical engineering college. I've been looking at schools like Georgia Tech, and University of Michigan Ann Arbor. I'm leaning toward Georgia Tech, but which college would be the best. My Reach is MIT, considering my scores are high enough. So if I magically get accepted to all electrical engineering colleges, which should I go to?   My potential college list: Boston U Bucknell U Carnegie Mellon U Cornell U Franklin W Olin C En Georgia Tech MIT Miami U Oxford Penn State U Park Polytechnic I of NYU Rensselaer Polytec I Stanford U U Calif Berkeley U Illinois Urbana U Michigan Villanova U Virginia Tech All offer Electrical engineering and rank in the Top 100 based on various US surveys and ranking list for Graduate Education

I'm part of an Engineering Club at my school and we're looking for future projects that just explore some ideas of Engineering in general. We would like to come up with our own ideas at some point, but for now, a lot of us are inexperienced, so I thought I could come here and find some stuff. So far, we have decided to build a bunch of Stirling Engines and use them for miscellaneous things, but after that, we have no other ideas. Could you guys come up with some ideas (possibly your own or ones that you have done), that are similar to this idea of teaching the basics of making things and stuff like that? Links would be helpful. Guidelines: Because we do this at school, there are certain rules that prevent us from bringing large knives and laser pointers on campus. Power tools and exacto knives are OK, though (IKR?). Also, because we are students, we have to scavenge around for materials, so unless it's less than ~30$, we might not be able to do that either.

I've been knocking around an idea in my head and I was wondering if anyone had an answer to a few problems associated with said idea. One of the problems/road-blocks is how do modern cars run? More specifically, is the gasoline that goes into the pistons for combustion an actual air/gas mixture, or is it air/liquid-gasoline? And is there a way to manually adjust the ratio of air-to-combustible? The reason I ask is because I was hypothesizing whether or not it would be feasible to replace gasoline with a more efficient combustible, and this combustible would greatly depend on what is actually put into a modern petroleum-based car engine's pistons. Thanks for any info!
