Growing up in Rhodesia (now Zimbabwe), we had fuel rations due to economicsanctions. We would use kerosene, which wasn't rationed, to run a Honda 50 Cub. For starting, petrol was used, then switched to preheated kerosene, which flowed through a copper pipe that had a wrap around the exhaust. We were just kids experimenting to get around the hardships we were dealt. These videos kind of remind me of my childhood.
Hola soy de argentina, mi padre siempre me cuenta que mi bisabuelo hacia lo mismo con el auto, lo prendía a gasolina y luego una ves calienta se cambiaba a queroseno.
My uncle spent many happy years in Rhodesia, he exported Rhodesian wine to the UK and made an absolute fortune from his Salisbury home, a shame it all went bad over there as it was such a lovely place... I have heard the oil shortage in Zimbabwe is so bad they had to dust off all their old steam engines otherwise trains would just not run in the country lol
The mixture of kerosene, castor oil and ether is the fuel that "diesel" model aircraft engines use. Most of these also have variable compression ratios. You back off the compression until the engine starts to miss, then raise it just enough to restore smooth running.
All diesel model engines has a variable compression, and the old recipe was 1/3 kerosene, 1/3 engine oil and 1/3 ether. Then there are semi diesels, they had a glow plug instead of variable compression, and runs on 80% methanol and 20% castor oil. But there are different oils to, and nitro methane is often used. I guess that this engine would be happy with say 10% nitro methane.
I remember experimenting with fuel composition as a school science project, closely related to my aeromodelling hobby. The glow plug engines could be throttled to produce a banshee like bowl which was great fun.
I used to do RC model aircraft flying, back in the 1980's. The aircraft used a John Oliver 3.5 diesel 2 stroke motor and was fuelled with Ether & Castor Oil. The aircraft was always covered in a sticky mess, after a day's flying and required cleaning. The John Oliver 3.5 diesel had variable compression, via a screw on the cylinder head. I've witnessed a CZ 250-471 Sport twin cylinder 2 stroke run on TVO (tractor fuel). It completed 31,000 miles like this, as a farm runaround work bike for 21 years. My friend bought it from a retired farm worker and it has been residing in his garage since the late 1990's. It still runs fine on the recommended 33:1 petrol-oil mixture, these days. Another CZ 250-471 Sport, turned up at a motorcycle rally, running on a concoction of cooking oil and methylated spirits, way back in the early 1990's.
this is great. thank you for sharing. i thought this technology was from scale model air planes. Back in the 1990s i bought a 1/10 scale gas truck. then i found a diesel head conversion kit from Davis Diesel Development. had more torque and more RPMs than glow feul. smelled like a Greyhound bus. i later modified the cylinder head to my two stroke dirtbike and ran Davis Diesel fuell in it. it worked. but i needed a variable compression head. my head volume stock was 12cc and i went to 7 cc wich was close to 20:1. today i still believe that it would be competitive if i could develop it more. thanks again for sharing
I met a lady a few years sgo who was running a bicycle with a Lohmann fitted, and I think I remember her saying that it was not a Diesel, but a compression ignition engine.
I love your slight danish accent! Great videos! As a professional mechanic it was sometimes a bit bitter to see how you treated this motor during overhaul. Good tools are a must. Using different screwdrivers (at least use 2 identical ones and use some Textile TESA adhesive tape "Gewebeklebeband" as protection on the lever surfaces) to pull a bearing or the like is unfair for this rare oldtimer motor. I forgive you alltough because you filmed everything xD . Please - next time use correct pullers and USE your Press! (You have one!, I don't but I have a fine lathe and a fine mill) I had my best childhood summer hoildays in Danmark. We went often to the Tivoli (København) and Billund for the Legoland.

Ja hat er gut gemacht. Aber das Lohmann Dinges war nicht der Hit. Ich kenn einen der hat auch so eins. Haben wir auch zum Laufen gebracht. Problem ist nur, wie im Video, dass man es extrem lange zum Anlaufen braucht, weil es heiß werden muss damit der Motor läuft. Also lange treten. Tu dir das ja nicht an, das Ding macht keinen Spass.
th-cam.com/video/HZFX_ZDdnAM/w-d-xo.html Trip with Lohmann bicycle auxiliary engines Diesel engine near Lilienthal near Bremen in northern Germany on August 9th, 2009. The Lohmann engine is a multi-fuel two-stroke internal combustion engine with compression ignition.[3] Its functionality differs from that of both the Otto and the diesel engine. Fuel is mixed into the intake air in the so-called mixer, so the engine has external mixture formation. The torque is adjusted by throttling the mixture with a slide. After pre-compression in the crankcase and overflow, the prepared fuel-air mixture is compressed so highly in the combustion chamber that it ignites itself. Since the Lohmann engine does not have a preheating device, the energy required for self-ignition during a cold start must be achieved in another way. To do this, the compression ratio can be increased by moving the cylinder liner by hand. When the engine has warmed up, the compression is reduced again. This also makes it possible to adapt the engine operation to the type of fuel used. The fuel used in the Lohmann engine should be as ignitable as possible, i.e. have a high cetane number.
The Drone Model Diesel engine was fixed compression and if you needed more compression, you just added more oil. If running Kero get jet A1 if you can.
Hello, what a nice little thing, which sounds like a satisfied hornet. When I was young, I drove a Velo Solex, 15 kilometres to the Highschool. In winter a diffikult task, but it went well. The only thing you needed, was patience.... with best wishes....Now, I´m 75 years old and ride two old Yamahas, a XV 750 SE 5G5 special from 1984 and a SRX 600 1 XL, one cylinder 4-stroke from 1989, which has only a kickstarter and needs sometimes 8-12 kicks to start, but it´s fun to drive this bike......
i just bought velo solex 2200 its a two stroke max speed is 20mph 49cc 2 stroke engine its a 1964 model hadnt gone in years so got it running and its does 100km to the tank i think thats a litre but really pleased with it considering they didnt really change much from 1946 i use it to get to work all week drive it to church which 25km return thats takes about an hour it costs me about $3.00 in gas maybe .50c in oil its cheap as chips to run.you still have to peddle a little bit on inclines but it assists great little bikes to get around on.Pretty reliable as well
Certainly seems to be quite the task finding the right fuel (and fuel ratios) to get this little engine putting out some power, all I can think of is that the earlier engines that Rudolf Diesel created ran on peanut oil, so maybe that would work, or would drive you nuts... :P
probably will be much easier to tune on some sort of test rig with a load on the wheel, like a generator with some nichrome wire spiral as a load. also there are alot of aps to measure speed. thanks for the video 👍
There was diesel RC plain engines. Not nitro but they had little adjusters on the head to change compression and no glow plug. They needed a special fuel but there is info on guys making their own fuel. Believe it used kerosene as well as some other stuff. Maybe that is the stuff you need?
Kerosene, Castor oil, ether, and a bit of “cetane improver.” The following is a semi-educated guess: 8% castor 10% ether, 2% “cetane improver”, Balance kerosene.
They talk about organic nitrates such as amyl nitrates and iso-propyl nitrates. Apparently you should not use them without knowledge because they can be dangerous? Therefore I do not recommend them. lol.
@@chevy6794 The additive that makes up about 2% of commercial model diesel fuel is amyl nitrite (not nitrate). Even in the 1960s this was difficult to buy on its own because there was some misuse of it that was possible. It is claimed to give smoother running when added to the model engine fuel.
@@cedriclynch oh ok. Thanks for clarifying. Either way maybe looking into DIY fuel for those can help. I know it was used as a drug or something. Looked it up years ago.
you should experiment with propane injection on diesel engines. On full size trucks, Bully Dog offers kits that produce insane amounts of H.P.!!!!! On commercial trucks we've been using "hot shot" propane injection kits for over 20 years.
QUESTION: could you add an electronic circuit to control the variable compression along with sensors to monitor the engine temperature? It would be nice to create an automatic version of this engine so all you would have to do is ride and change fuel when it gets low.
Hi buddy!! Cool bike. The only personal experience I've had with a bike like this was a solex 5000. It put a smile on my face. But probably not very practical for everyday use 😕....
I had a 1976 Datsun pickup truck that I had for five years. The years took their tole on the ancient truck. When I became financially stable, I decided to experiment with the Datsun since I had bought a new vehicle. I decided one day to fuel it with diesel. That pickup truck ran far better on diesel and went much further. However, the pickup truck left a fog bank behind it everywhere it went. Turning off the engine was an adventure. I would turn off the key and the engine kept running in a very sickly fashion. I had to go under the bonnet and put a lid over the air intake.
Kerosene, oil for lubrication, diethyl ether, cetane Booster (amyl nitrate) no more than 2% are the ingredients for model diesel fuel, not truly diesel engines but some kind of hybrid compression ignition.
The variable compression and the need for premix tells this is actually an HCCI engine, not a true diesel. Maybe a cetane improving additive might help with combustion speed
Isn't Ether actually counter productive? It and start spray in general behave more like gasoline, so they will actually increase the fuel's resistence to self-ignition under compression, which is the opposite of what you want in a Diesel engine (or a multi-fuel engine that relies on self-ignition).
Squirting ether into Diesel intakes when cold is a well known way of getting them to start. Adding ether doesn't affect the cetane rating but it does mean that any ignition at all spreads faster.
Ethers are condensate molecules composed of 2 alcohols (usually methanol) joined by a fairly unstable -O- bond made by removing an H2O out of the two -OH on the alcohols. When this fragile bond breaks at ignition temps, it forms alkyl and -O* radicals that then go around brutalizing any nearby molecules, which is why it works so great as a starting fluid in compression AND spark ignition engines.
I remember watching a guy on You tube say you shouldn't use a fuel filter on vehicles with gravity feed fuel systems, do you think this could affect your bikes performance.
That engine should make about 1/4 to 1/2 of a horse power if it was a well designed system. It really should be spinning faster than what it seems to be and the exhaust pipe looks too short. The exhaust pipe can matter a lot on a two stroke diesel engine. It can work to help get all of the exhaust out of the cylinder so the next cycle uses only fresh air.
Try some linseed oil, burns very well in 2 stroke engines and was once used as a basis for racing 2 stroke motorcycles but you don't want to run it neat as it will put a hole in your piston so needs to be heavily mixed with something less energetic. I ran my first motorcycle using a good dollop of linseed but man it smells bad, I killed my first Vespa using linseed as I did mix it linseed heavy and boy did the 125cc Primavera top the 90 mark it soon died with a melted piston crown and lots of piston bits mangling up the internals...
What is this engine? I just found out your channel, and this engine is super intriguing to me, can you share the links of your older videos with this engine? Or make a detailed video of this engine? Like how much power it makes, fuel economy, peak rpm, etc. and where did you get this engine from?
Love theae little motorized bikes the United States isnt very happy with them. That would be great if a company made a new diesel model. Its definitely needs more tuning. I don't think it liked the mystery fuel
This is cool, there is a chap near me with lots of VeloSolex in various stages of repair, and I fancy getting one to play with. But first I must fix my Visa GTi
You could send a sample of the fuel to a lab to get it analyzed. This way you'd find out the composition and ratios of its constituents. Alternatively, you could distill it and get a hint of which substances are in there and how much, by observing the temperature of the vapor from each fraction that comes over.
This little engine reminds me of the diesel engines that I used to power model aeroplanes many decades ago. Have you tried that fuel? It was ether and castor oil, if my memory serves me well. Readily available.The main problem here is that 18ccs are justnot enough. 25 might do the trick. Fascinating stuff, nonetheless. 🫣

Pre heating isn't really needed once the engine is warm, but it's not a bad idea.
I went to Zimbabwe some years back... amazing country!
And amazing story! It inspires me to try that out on something one day...
You weren't kicked out of English class, its perfect. 😊

Yes but measuring the temperature to determine how much compression is tricky. Generally thermocouples are millivolts and very susceptible to noise.
My Puch does 50. Diesel is OK, but might want a larger displacement.
The engines were started with low compression then the compression was increased to optimum, you could tell by the rpm.

maybe -2 today.. so not that bad...
Great!
Now get a Trojan mini motor. Arguably the best clip on bicycle motor. 😊
yes please!
I had one as a boy but it used to eat tyres,had a syncromatic powerpack too that had a cluch.
Just add a hint of 2 stroke oil in the diesel.
Fantastic.
You can hear it "four-stroking" sometimes, which usually means it runs too rich.
Not in this case.. its the variable adjustment of the compression... its very hard to get right..
I never saw a diesel engine that small 😂
Love theae little motorized bikes the United States isnt very happy with them. That would be great if a company made a new diesel model. Its definitely needs more tuning. I don't think it liked the mystery fuel

You could send a sample of the fuel to a lab to get it analyzed. This way you'd find out the composition and ratios of its constituents.
Alternatively, you could distill it and get a hint of which substances are in there and how much, by observing the temperature of the vapor from each fraction that comes over.

This little engine reminds me of the diesel engines that I used to power model aeroplanes many decades ago. Have you tried that fuel? It was ether and castor oil, if my memory serves me well. Readily available.The main problem here is that 18ccs are justnot enough. 25 might do the trick. Fascinating stuff, nonetheless. 🫣
