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.

50cc 2 Stroke Tuning? Answered

I have an old moped that I got for cheap and I am trying to fix it up. I replaced the carburetor and the new one is a little bigger even though it is off of another 50cc. It insisted on running extremely lean, but I was able to get the fuel/air mix balanced by putting some foil tape over part of the intake to get more vacuum behind it. It will only run right if the exhaust is on so that it is not lined up perfectly with the exhaust port on the cylinder. If the exhaust is taken off it will start first kick, but if it is lined up the way it should be it will not start. I took it off today and when I put it back on as close to the way it was before it would start but is now running very lean, beyond what I can tune out with the carburetor. If I give it full throttle it bogs and has no power, but it has fair power at 1/3 to 1/2 throttle. It also is getting really hot and has absolutely no power once it gets very hot. Yesterday I hat it all just right and it ran with none of these problems except that full throttle was still not where it got full power. Does any one have any ideas about what I have to do to make it run right? Maybe there is no option but careful misalignment of the muffler? --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- It turns out that the problems were that the muffler was clogged, and that it was running too lean at first, but too rich once it warmed up. Thank you for you suggestions.

How does this engine work? Answered

I have a mini moto engine which i'm going to use to power a go kart type thing. I need help identifying the different intakes as it looks like there are three holes. I think the middle one is to attatch a throttle cable, but what of the other 2? One already has a pipe attatched to it (right hand side) and the other (left) looks like it has a fuel tap. I'd guess fuel and oil, but I always thought that had to be premixed, so shouldn't there only be one hole? Any help in identifying the different bits would be appreciated. Chip.

Paper two stroke hydrogen engine

 Ok so I have this crazy idea to make a two stroke engine out of paper that runs on hydrogen and well ive allready built part of it just the piston head and cylider and stuff but if i lined the inside of the cylinder with tin foil would that be enoth to keep the paper from burning? and so ya anyways the engine of i have made allready is very sturdy each peace is 10 sheets of paper or more compressed for over 24 hours  now the compression im not two worried about because its more of the sheer pop of the explosion that will push the piston down well i guess thats how it is anyways but if the gas ignites anyways with oxygen why have compression  for this anyways because the explosion is going to be soooo small anyways that it wont really matter much.  the overall size of the engine is about almost 2" tall by about 1" wide on the widest part the bottom . So um I know by now im classified as "CRAZy" but that asside can i get some opinions and ideas plz. thanks MRN

Question by Leachie01  


So I got this awesome idea to make a trike with a snowmobile donor. Use the snowmobiles motor and track for the rear "wheel", and a gokart style front end, with 2 wheels, spindles, maybe suspension, etc.  Nothing too big, maybe 400cc or less. 2 stroke of course =D. I am proficient in fabricating, welding, and have a full auto shop worth of tools, so the actual construction shouldn't be a problem. However, I need to know some things about the snowmobile drive train.  Would the track itself work on dirt, light mud, light puddles (2-4 inches deep), and maybe some sand? If not, are there any tracks available for such terrain? Do most snow mobiles have the engine mounted infront of seat, below, or behind? This thing looks wicked cool in my mind.  OH, heres a good way to put it. Like a snowbike (Dirt bike with tracks in back), with two front wheels. Or a honda ATC with tracks flipped rear/front.

what do you do for the gas/air ratio on a weedeater 2-stroke? Answered

i made a motor bike and i rode it over 137 miles so far, it hasn't given me much problems except one day it lost compression so i rebuilt it and i put in a new sparkplug and rebuilt the carb after it was running better than ever and the next day i went to ride it and it wouldn't start so i cleaned the carb again, then it was working again but it was like there wasn't any gas, i used to be able to go 29mph now i can only go 16mph with the wind, if i give it too much throttle it will bog down and slow down, so i can only give 1/4 throttle. i have tried messing with the pin in the carb and the tuning screw but they don't seem to do any  thing, what is wrong?

Does a 2-stroke Honda CB 100 NE engine need a battery to run? Answered

I have a Honda 2-stroke CB100NE (1018034) engine which I am trying to get working. This is the first time Ive worked with an engine so my knowledge is quite fragmented. So far the engine will turn over using the kickstart but I've been unable to get a spark. Documentation for this specific engine seems to be quite limited but I found a service manual claiming that the generator goes into the battery which then drives the spark plug via the coil, points etc. However, a friend told me that the spark plug can be run directly off the generator/magneto, and since the engine isn't in a motorbike which would require lights and a horn the battery isn't necessary. I'm also not sure how the rectifier plays into this if I'm not having a battery - is the rectifier only there to facilitate charging of the battery? So my question is, does my engine need a battery to power the spark plugs and if so, do I need to use the rectifier? Any help would be greatly appreciated.

Can Non-Hybrid Cars Get 100+ MPG Today?

  We're not talking about hybrids here; our topic is cars powered by the basic IC-engine that relies on gasoline and not electric motors. Today's gasoline engines are not designed to combust/burn gasoline efficiently. Even with the advent of using high pressure fuel injection techniques that are computer controlled, we still fall short of the mark. Partly because liquid gasoline can't burn, only gasoline vapors burn, and there lies our problem. The same goes for injecting the high pressure droplets of fine-mist liquid gasoline that enters the engine cylinder using our current nozzle ejector technology, it doesn't all burn at the same time! Engine designers assume that these droplets are instantly vaporized by the engine's hot cylinder walls, and then instantly explode/combust when ignited by the sparkplug. Not true, up to 2/3 of the fuel isn't vaporized and doesn't combust until later on in the cycle. The 1/3 that gets almost-instantly vaporized and burns will do so within the several thousandths of a second (Fig-1) it has before the piston moves down its 1/2-stroke (out of today's 4-stroke cycle) completing the engine power-portion of its cycle. This releases power and tremendous heat which indeed vaporizes the remaining ~2/3 of our fuel from its liquid droplet form, but too late. It essentially does so when the power stroke is almost over or the piston is just about ready to move into its up-stroke (2nd stroke of our four stroke cycle) phase. So, because of poor vapo-timing we have 2/3 of our fuel virtually wasted by exploding at near the bottom of the power stroke. This incorrect explosive timing, which happens to most of our fuel, imparts very little energy into the crankshaft because its effective "moment" (a product of explosive force and radial-component distance from crankshaft center) is insignificant by then. Various attempts at adjusting the combustion timing spark hasn't made a significant difference. Even though ~2/3 of the fuel is now exploding and providing a huge force, its small "influence" arm distance is rapidly diminishing to zero, and any huge downward force times near zero arm-length is still zero. Some clarification here, technically thermal-efficiency is not improved, pretty much all of the gasoline gets combusted today. That means the energy of the fuel is almost totally released, but not effectively used. The problem is the timing it takes to convert fuel-injected gasoline droplets into vapor to combust at the correct engine rotational time and extract that expended energy. If you did the math for any size engine rotating at say 3200 RPM, you would find that a 4-stroke engine can only extract that energy from combustion during one of the four strokes. And the time it takes to make that stroke happen is only about 9.4 thousandths of a second or 9.4 milisecs (msecs). Now picture the piston just below TDC, all its valves closed, under pressure and containing all the fuel and air it needs to combust. At this point our deadly cocktail has about half of the 9.4 or about 5 msecs to complete combust after the timed sparkplug ignites it. The half factor exists because the max portion of our power stroke (moment arm) occurs at the mid-stroke of the piston sliding down and turning the crankshaft. If all of our fuel isn't combusted by then, the moment-arm or distance from the piston-center to the crankshaft quickly reduces to zero. Again, only vapors combust within a healthy 2 msecs (Fig-1), while fuel droplets take a relatively long time (>5 msecs) to vaporize before it can combust. Unfortunately nature is stubborn and vaporizes ~2/3 of our injected fuel droplets only during roughly the second half of the power stroke. So this huge amount of energy gets wasted because even though the forces of combustion are huge, its moment arm is rapidly approaching zero. Infinity times zero is still zero! Engine designers/engineers have been plagued by this phenomenon ever since the creation of the 4-stroke gasoline or Otto cycle engine. We need to improve this intermittent combustion/explosion process by combusting all of our injected fuel at the correct timing sequence. This is accomplished by injecting only vaporous fuel which will produce ~3X the power we now get. Another way to state this is, for the same power that we now get from a gasoline engine, if we burned the fuel correctly, we would only need 1/3 the fuel consumption to get 3X the current MPG.

New Sport!! Combine Golf with Archery!

I have an idea for a new sport. If you combine golf with archery, you'd get Golfery! The concept is simple with only some minor modifications. Arrowheads now have a golf ball or ping-pong ball for a head. To get a hole in one, the player must hit the flagpole in the pocket. There are (3) 1 foot wide rings concentrically spaced around the flagpole. Inner ring = 1 stroke, middle = 2 strokes, outer = 3 strokes. If the arrow lands outside of the outer ring, the player must pick up the arrow and gently toss it underhand towards the pocket. Other than that, the standard rules of golf are followed. I don't have the equipment to test out my ideas. If someone here would try it out and PM me with the results and any suggestions that would be great.

Striking Clock circuit -

I am a hobbyist trying to add a striking feature to an existing clock.My clock is a quartz movement with a set of contacts that close briefly every time the hour hand passes the 12 position. This pulse is used to trigger a solenoid which when energised causes a plunger to strike a bar and produce a resonant bell sound. I include the cct. I am currently using. The 6v. battery powers the 10 ohm solenoid coil & U2 the LD1117 IC which provides the 1.5v needed by the quartz movement. My project is to change the hourly strike from a single stroke to one which strikes the hour the correct number of times to indicate the time, the same as a mechanical striking clock does - 1 stroke at one oclock - 2 strokes at 2 oclock etc.continuing to 12 and then beginning again at 1 oclock. Unfortunately my electronic ability does not extend to using counters and timer ccts so I am looking for help with my project. I would greatly appreciate any help with the circuitry needed to allow me to complete this project. TIA, RMHC.

Has anyone made a solar heat powered Fluidyne stirling engine air pump?

So, I will start with what I have in mind.  (Might be total rubbish because I don't fully understand).  You have a solar collector box, not more than 1 meter square.  painted black 1 to 2 cm deep,   and probably with glazing over top. The box itself is metal fully closed up and the back is insulated.  From the box through the insulation there are some metal tubes that go to another box at back for the cooling chamber. Tubes are constricted so the air sprays through to the cooling box and it goes into steel wool as it expands. On the reverse stroke, it does not go so much through the steel wool because the nozel constriction is  on that side not the hot side.   Power is taken away from a liquid piston somewhere attached to both chambers  or a diaphragm at the back. (It can be water cooled). I want the strokes to be long and slow. Can it work?   Temp difference will only be around 40 degrees C and the pumped air ( 2 valves  in chamber off of liquid piston) only needs to go to 2 psi. )    I have been in contact with a guy in Germany who made Sterlings that worked with sun heat.    But he didn't use Fluidyne (also called liquid piston stirling) and he did not pump air.          My specs are extremely low, I only need 60 litres per hour of air at 1 or 2 PSI.  It would be very cool to make it from such basic materials.                 Thanks Brian

How to get a linear actuator to open & close a door & switch a relay at the end of the stroke so it reverses direction Answered

 It would be simple with a manual relay switch but  I don't want to have to be there to throw the switch. I want a timer to do it each morn and eve so the door opens at one time then next time timer comes on it closes. The Linear actuator has limit switches to stop the motion at the end of the stroke. I need the next time it powers up to reverse motor direction.  Also will need to get power from 110v timer switch to 12v power supply to the LA    Also if it is powered from the timer I use now to power the lights, they will stay on for 2 hours then off. So the relay must not send power back right away but delay until the power goes off and the next time it powers up then send it to the LA. Or I need a separate battery power source and timer that will just give power long enough for one stoke then off. Not sure how to do that. Any electrical wiz kids out there can help me with this?

The designs were simple and they were work horses. Our new high horse powered gas tools often cann't do nearly as much. The old machines used heavy flywheels; slow to start but they kept on rolling. With the improvements we've made in bike gearing systems why not make a pedal powered tractor that could do serious work with that same heavy flywheel technology?
