Or you could build a small bubbler (waterpipe styled provision) and let the engine breathe part of its air through that. That way, you will get a very fine mist. It WILL evaporate the methanol first though, so not suitable for water-meth mixtures.

This needs to become a five-seater, all seated one behind the other, a là Twizy, and a roof, again, like Twizy. And yeah, a diesel would be in place.
I was waiting for something like this to come up for years.
Cool machine.

On the water injection thingy: If you cannot inject an amount low enough with what you have tried so far, maybe you could use a small carburetor or a bubbler ("water pipe"), use a really narrow hose to connect that to your air filter housing (will need own little air filter). Connect throt...

Hey Otto! Little question: When you decided to supercharge instead of turbo, have you also thought of using the old petrol engine as your supercharger airpump? I mean, instead of straight-shaft cylinder off, you could have welded the ports shut, poured some 4stroke oil into the crankcase, and replac...

Be interesting if they can make a 2-stroke pass 2018 Euro 7 emissions. I haven't seen a new 2-stroke in an on-road vehicle since the early 90's with Detroit's 8V92T. This one looks like it's got two overhead camshafts. Meaning it's probably loop-scavenged... through the valves, not ports. Meaning n...

Not sure it belongs here, the vid being of 2015.1.1., but since there is a lot of progress to be seen there, I'd say it is, technically, still 2014. Should I have missed a thread dedicated to this build, I am sorry, and Admin please feel free to delete this post. So here goes: 2WD Hydrostatic V-twin...

So, what about the homebuilt engine? Can't wait to hear the details

The Estonian half-a-Ford machine sports an ample juicy sound. Commented on 'tube, inviting the author to this forum - let's see if he's interested in sharing.

Homebuilt engine? Now that's something I'd love to hear more about Displacement, cyl count, layout, injection, induction? 2 or 4 stroke?

THAT bike! Pure rat goodness, and very clean at that - almost bobber-clean. If you disregard the wires, at least +3 to rattiness for being a diesel, too

Re decompression device: Is there is no possibility to retrofit your engine with one? If none are ready made, fabricate one yourself. They are pretty primitive, esp. if they have manual release. Failing that, you could ease your engine starting work by putting a throttle body into the intake duct. T...

Hell yeah and more power to Renault, I say. Shouldn't be much (if any) heavier than the Smart 800 ccm common rail turbo-diesel - at double the power. Let's just hope this one doesn't get dropped as have all previous attempts to re-introduce two-stroke diesels to anything smaller than a ship...

Vaporware. Like algae biodiesel and hydrogen fuel cells. No doubt their project is, yes. I recall having browsed their homepage a coupla years ago, and it is now still as it was then. Got me wondering if it is due to their funny "z-process" combustion differing little from the M-process, ...

Shout out to the thumpin' massive! Having almost no free time due to half-time work, other half-time study I am restricted to posting all kinds of drivel removed from reality on this site instead of building my own diesel bike or meddling with my diesel engine. So please bear with me a lil' while lo...

If you are stern on going the Ural/Dnepr or old-school BMW way, there's also the possibility to walk this way ; just watch the vid and read the topic. Not saying it is THE easiest way to go; just that if you chose to, you would not need any frame mods because the engine pretty much stays put; no nee...

If you open the exhaust valve very early then you're just reducing engine crank output to drive the turbo instead. This is a much less efficient way to extract energy from the fuel so your fuel consumption will rocket. Not quite. See, once the turbo is up to RPMs so the boost is at a level that tur...

Good time o'day everyone! Another stupid idea incoming. As we all know, our little industrial singles are hard to get a turbo to function on due to two reasons. One is pulsations - a properly sized plenum chamber might mitigate this. The other one is the insufficient gas flow available: There are fe...

You also need extra air for that extra fuel - whatever it may be, so only really useful if you have a turbo or supercharger in the first place. If you did then why not just ramp up the diesel rate to use the extra air? LPG is popular because it means you can leave the standard injection system alon...

Now, a little question:

What is the rotating speed of the centrifugal smog pump(at least as specified on the motor)?

So this showed up recently on local kijiji: http://www.kijiji.ca/v-business-industrial/edmonton/wisconsin-diesel-motor/1007782795?enableSearchNavigationFlag=true $200 cad. The owner claims it ran well last summer. He has never used the engine for anything and knows nothing about it. It is labeled a...

I was serious but Ill take a laugh where I can get them. :mrgreen: I have too little clue about comparable comlexity cost and efficency nor weight between an electric and hydraulic front drive wheel to take a stand either way except that electric bikes are have been on the market for a few years no...

Definitely. Even though it is not sure whether it is a diesel or a gasser (no large pictures, no close-ups), it is still a demonstration of what is possible with a car engine, so definitely of interest to people on this board. Plus it IS a beautiful ratbike (is that even possible?).

For reverse go with a second Alernator and Copacitor (or large primary alternator). Put an electric hub in the front wheel. Now you got reverse and an on demand 2wheel drive. Reverse, OK. But 2WD? An affordable in-hub motor has how much, 0,5 to 2 KW. What's the point? Especially since for muddin', ...

Well, the package would be far more neat and acceptable for longitudinal mounting if it only had the CVT, sans gearbox. When I erase the gearbox from my mental picture of that package - just the CVT doesn't add all that much bulk even as it protrudes to the side somewhat. Driver's legs go well over ...

Meanwhile, on German eBay we see cgi.ebay.de/ws/eBayISAPI.dll?ViewItem&item=151350768467&fromMakeTrack=true&ssPageName=VIP:watchlink:top:de a 18 hp double-barreled Slavia lump located in the Czech Republic, 46401 Horni Rasnice. Worthy candidate for a Ural/Dnepr rig? Should anyone happen ...

Ah yes but it would be virtually a straight swap and you've got your extra 3 hp with no hassle :) that is true. Has anybody every dynod them, 3hp from 50 cc seems quite large? Why, swirl-chambers are usually more powerful than DI and ante-chambers are more powerful than swirl-chambers as far as we'...

Beautiful in a ratty-bobberish sense Not a common combination to see - let alone so well executed.

Oops - typo. MT-10, not 12 :D More info: Compression ratio is approx. 22:1, Viktor got it up that high by using VAZ(LADA) 2105 piston heads (they aseem to be same bore as MT-10 ones but taller) and by forming the cylinder heads in an appropriate manner. Heads are home-made, cast from some sort of si...

I quoted a vid of an MT12 engine converted to diesel operation some posts above (or some months before). Now I was able to make contact with the author, a Ukrainian guy named Viktor Kutsenko, and here are the details I could get from him. Modifications to the engine are not as big as one might have ...

I suspect any discussion of Alex's bike producing 15 hp in the hope of 65+ mph is largely theoretical. As such, the engine itself presents a far greater risk to life and limb than does the prospect of an uncorked and lit propane vessel. Perhaps the worst-case-scenario would be having the engine she...
