can we use the magnetic attraction and repulsion in petrol engine? Answered

Instead of using compressing of gas using  combustion and passing gas and using spark plugs ..... shall we use a dipole magnet in the place of spark plug and and a magnetic piston with a pole on top side.if we rotate the magnet at the spark plug place ,when the opposite pole comes down .......the piston due to attractive force goes up and when like pole comes up it will get repulsed and goes down by this crank can be rotated.this is basically based on the principle of magnetic attraction and repulsion........ i am just a college student its just an idea that came into my mind......please say whether it is possible or not...

Petrol/diesel still separator

Ok so is any one game to make a basic still that will evaporate petrol into vapor and then reform via cooling into petrol? Where a vehicle that runs on diesel has been filled with petrol, this device could save $1000's. No spark or naked flame to a 100 degree max temp will be safe. there's a challenge! PS garages will give you this stuff for free.

measuring petrol/ethonol accurately

G'day All, If this has been done before, I apologise, but I have not found anything when I have searched. I am a team manager for a team of students who need to design, construct a three wheeled vehicle. The test is a 24 hour "trial" (more like a race ;-) ) We have been competing in a category for "Hybrid Vehicles" which an additional power source to asssist the rider.  In our case it is a 50cc engine using a friction drive arrangement so we can disengage it if required or if we desire.  The reason for this is that we only recieve 3 litres of petrol for the event............  This is my problem.  I have not been able to measure petrol in the tank accurately enough.  Over the last two years I have had one litre left or ran out after 21 hours.    I have been thinking of using a strain gauge or load cell to measure the weight of the tank.  I'm thinking it could be as simple as powering up the load cell with the appropriate voltage, and measuring voltage drop across it, maybe with an added resistor. Or it could be made more complex by using a circuit to drive a number of LED's giving an indication of the fuel in the tank. If anyone outhere has any ideas to do this simply and reliably, I would love to hear from you.  If it is more complex then so be it. Here is a link to the event to give you an idea of what it is about http://racvenergybreakthrough.net

HHO generator improves fuel efficiency of petrol engine!

Reproduced verbatim from The Fortean Times issue 249, republishing from FT35JUNE 1979On the 15th a demonstration of a "revolutionary" energy device took place at an undisclosed location in the UK. Iowerth Thomas, 58 a Welsh inventor, hoped to interest both government energy officials and an Arab consortium. Mr Thomas had been experimenting since 1936 with ways to make petrol engines burn more efficiently. His "bolt-on" device promised between 25 and 40 per cent efficiency using "the electrolysis of tap water", plus a cleaner exhaust. The government scientists' response - that it was impossible - spurred Mr Thomas to demonstrate it for them. He reported to the motoring correspondent of the Daily Telegraph that his stationary engine ran for 112 seconds with his device and for 77 seconds on the same amount of petrol without it. The usual objection to electrolytic systems is that the energy needed to run them is greater than that produced. With some sarcasm, New Scientist sniffed that the device needed to be much smaller than the room-size contraption Jones used. What really stoked their scorn was Thomas's reply when asked how it worked: "It's beyond me," he said. That was the last we heard of him and his promising device.How has this technology improved in the last 30 years?L

Propane used as fuel in Petrol generator?

Hello, Please read through this thoroughly.  I'm planning on buying a petrol generator and running it on propane however I wish to still be able to use petrol without too much hassle, I have made some plans on which components need to go where and what I need to buy. I have a fairly good understanding of how the, engine, carb, fuel tank, ect works. I was just wondering if it would be safe and if it could cause any problems to the generator or even me (explosion hazard). I have uploaded a picture to demonstrate what I mean press the I at the top left hand corner to make the photo bigger :) This is a 4 stroke engine so it has a reservoir of oil built in to lubricate all the components as necessary to keep the engine running   Things I need to know. Will it damage the engine not being lubricated and cooled by petrol. Could the propane tank/carb/engine or anything explode? - is it likely Are there any other risks I have overlooked. your opinion of the design if you think it will work and any tips on making it better. Stuff I'm using: -  most will be bought on eBay Generator -  1kw not 100% decided which one I'm getting.

Can diesel be separated from petrol?

​this is a reply to my last question as for some strange reason I can't reply and leave a comment to the thread. ok thanks to those replies,  I am in oz and the reason I've asked is due to free diesel that has been contaminated with petrol being offered to myself. So, given I have free fuel I am prepared to treat, separate, spend some $ on in trying to produce diesel and petrol separate. I have looked at a continuous separation distill unit but I don't know how it works and the safety factor, don't want to make a bomb! Other ideas are leave the diesel out in sun and evaporate petrol(not so good for environment and water getting in diesel) or add oil to mix. Most of the fuel mix is majority petrol and minority diesel, although exact ratios are unknown. I have run my lawn mower on it quite well so given that it is mostly petrol, can I either;1. Add more petrol pure to further dilute the diesel. 2. Add an octane booster to over come the diesel influence. And specific comments and answers appreciated

Diesel/petrol mix in old engine?

I can't seem to respond to messages on answers? Help admin?  ​thanks cyber for you comprehensive answers. I have since put in hi octane fuel as my car started running bad and then stopped due to, I believe, the diesel sitting in the bottom of the tank and now being the majority fuel source. The hi octane fuel got me going but only at idle speed, no acceleration. I got home. It's like it floods when I try to accelerate from un burnt diesel. According to your post above, hi octane fuel makes it worse. I will drain and leve for lawn mower, which works well. That bring me to another possible use. An old engine,carby with not cat converter and 10percent diesel? Yeah I know, give it up. I guess what I would really be happy with is, what can I use a diesel/ petrol mix fuel for?

Can a diesel run on 2stroke fuel/be supplemented with 2 stroke fuel mix? Answered

Hi all can a diesel run on 2stroke fuel mix if the 2stroke oil was added to the petrol in heavy enough quantities so that 1. It off set the octane rating of the petrol so that it acted like diesel? 2. It was blended with diesel to supplement the mix?  The reason I ask is that there is a lot of mistakes made at the fuel pump with people putting fuel in diesel and I was wondering if the petrol was know, that a measured amount of 2stroke oil was added that this would solve the problem, rather than the expensive issue of towing, draining and repairs? I have had this experience and drained most of the petrol and then added motor oil to the new diesel to help lubricate and no dramas. Positive comments please.

Hello,  I own a non-profit organization in the island of Tenerife, Spain. We have established in an old house that was from my grandpa. We are there since Novenber 2010. We tried to sing up with a local enterprise that provides electricity but they told us that we had to make some changes in the house, we did it but they still without providing us electricity so we bought a petrol generator that provides us the only source of electricity that we have, but petrol is a bit expensive and the generator is noisy.  Mi intention is to set up solar energy sometime in the future, but is a bit expensive for us by the moment. Last mounth I bougth an inverter-charger and a gel battery for charge it temporaly with the petrol generator, saving energy, however I believe that they are bad connected toguetter because the battery doesn't charge. I don't have a lot of knolenge about this matter so I need help.  I attach some photos of the battery and the inverter (is a charger-inverter in fact).

Why does an internal combustion engine have to run on liquid fuel?

However this does not mean that that it would be impossible to introduce a solid chemical fuel broken down into a light powder. The problems would be to identify a suitable fuel and its costs. It would obviously be necessary to dispose of combustion by-products with minimal polluting effects. Does anyone have thoughts on this or do you think its a non starter?

Pre-purchase questions of a petrol-driven electrical generator - cos you guys know best! Thanks!

I have a caravan in a remote location and I've got round to thinking of buying a petrol-driven electrical generator. I'm figuring on using this with an ethanol (E85) fuel. I'd really appreciate some help if you can to any parts of my queries. I have looked around on Google for advice but there's a lot of conflicting stuff as usual and I know you guys are good. My normal max load is around 4,500watts but I have security HID lights which have a huge inductive start for a few millseconds - how will a suitably rated generator cope? Do I always add a 20% margin to the generator capacity so for a 4.5kW load I should get a 6kW machine? Or is it not 20%? Given that the machine will be outside, I don't want to annoy the other caravanners, so if I build a sound-proofing box with just an outlet for the exhaust, could I expect the noise to be reduced signifcantly, given a lot of noise will be coming from the exhaust itself? The machine has a tank of 15litres but I want to increase this safely - how could this be done, if at all? Safety is paramount (naturally) but then so is convenience. Do you have a generator? If so, what do you wish you knew beforehand or any regrets? What kind of maintenance schedule is there and is there a performace improvement for modding the air-intake to a larger filter like for cars and bikes? Many thanks for reading my question and thanks for your time to reply.

Is there a variable im not considering?After 4 months of weekly refills I feel that conclusively, one stations fuel seems to combust better than the others.Is this possible and if so are there any home experiments I could try to prove my theory via testing the fuels combustion/quality.I only write this as I sit here on a week, where I was forced to fill up at the "suspect" station. Im on day 3 now and my fuel is red lining... What is happening?I know the difference of 3 -8 days is a massive, surely others would have noticed this also. I thought I was mistaken the first few times it happened. But now I am positive, something is wrong.I might add, I use premium fuel with the same octane level at both stations.Could that be it? Would they be mis-quoting the octane level in their fuel? That is the only thing I can think of.

Brushed DC motor HP requirements for Longboard? Answered

So I have 2 brand new tilt/trim pump motors and thought about making a set of matching electric longboards since products like Boosted Boards seem to have become fairly popular.  I am not too sure whether the tilt/trim motor would be strong enough though, they are a decent size motor though.  But it got me thinking what size is required for an electric longboard? The main problem with the tilt/trim pump motors is that I can't find specs on them anywhere, just specs for tilt/trim pump assemblies they are off of, but nothing about the motor itself other then SAE J1171 Marine rating.  Because of this I thought of buying another DC motor to do the job.  (Picture of tilt/trim motor) The constraints for me is that I have a couple 12 - 24v 100A motor controllers already, for brushed motors only.  As well, I want to just pick up a couple cheap $40 12v, 24AH Sealed led-acid (SLA) batteries from the local Ace Hardware and run either a 12v or 24v motor.   Options on eBay for affordability purposes range from 12v, 24v, 90v and 180v dc, obviously 90v and 180v are out of the question.  Looking through the 12vdc and 24vdc motors, there are many fractional HP motors available.  I was looking at something like this; http://www.ebay.com/itm/172252712203?_trksid=p2055119.m1438.l2649&ssPageName;=STRK%3AMEBIDX%3AIT Running 1/4 HP at 24v, would 1/4HP be enough though?  I know electric motors HP ratings are lower then petrol engines, a 6.5HP petrol go kart runs about the same as an identical kart with a 1HP electric motor. If that isn't enough I am thinking a 2/3HP motor from Holley might be better? http://www.ebay.com/itm/361524972024?_trksid=p2055119.m1438.l2649&ssPageName;=STRK%3AMEBIDX%3AIT Wondering if someone has an idea for sizing.  I know lots of eBikes and Chinese electric mini bikes and things have 500W motors, so roughly 2/3HP, so I can't imagine I need more then that.  As well I don't want it to go too fast (fear of speed wobbles) but if anyone would have an idea of sizing that would be super helpful!

International zero-emmission motorsports

The world's first international hydrogen-powered motorsport race was held in Rotterdam this weekend.Dubbed the Formula Zero championship, the contest pitted teams from five countries against each other in a zero-emissions go-kart race.Each team's entry was powered by a commercial fuel cell that produces electricity from hydrogen. It may be small-scale, with only six teams entering go-kart sized vehicles, but Formula Zero is an officially-recognised motorsport, with plans for scaling up to Formula Three and the Formula One style and speeds."In 10 years if the motorsport industry as a whole hasn't engaged in zero or low emission principles, it probably won't be around," said Greg Offer, who headed up the Imperial College London team. "Teams that embrace this new technology early on will succeed, and those that don't will fall by the wayside."Racing excitement won't suffer, though; Dr. Offer says that fuel-cell powered vehicles don't represent a compromise in performance over traditional petrol-fuelled engines.'"With a combustion engine, you have to reach three or four thousand revs to get your peak power," he says. "With an electric vehicle, it's all there from standing, and they're more efficient." The next races are planned for the US in March 2009. Plenty of time to get your own entry built.Imperial TeamFormula Zero homepageBBC news article

Thoughts on modifying a mower to a dethatcher?

Briefly, my lawn is a mess and I cannot afford either an electric rake or dethatcher. I have tried using a spring-tined rake to dethatch the lawn but it is too labour-intensive - and I have around 250m2 to cover - not for the faint-hearted! However, I do have a petrol rotary lawn mower and a spare blade. I have thought of combining the spring-tined rake to the blade to dethatch that way. I don't mind the thatch not being collected - as I expect it will leave the mess on the floor - I can simply dethatch at a higher blade height and then cut/pick up the mess on a lower blade setting. I don't have a welding machine, nor access to one. So I wondered if the good people here might lend me their brain cells to consider (a) what I might use as a rake on the blade and (b) how to secure it on to the blade. I have seen one of those rakes which can be spread at will and I thought to size it and secure it with a metal band and rivets - and then rivet the whole thing to the blade. What do you think? I had also thought that I could fix the rake on the opposite side of the blade. The blade is not reversable/obversable - there is a one-way key that oreints the blade to one position only. Please do not trouble yourselves with warnings about safety etc as I think I am aware enough to consider this for myself - unless it is to say "don't do it". I also know about having to balance the blade weight. As ever, thanks for reading me and thanks for your time to reply.
