First start of my Krimo 35hp crude oil/hot bulb engine. Started right up on the first try, as they should. Made in the late 30's by Kristdala Motorfabrik. The Tractor is a Bolinder Munktell modell 20. 40hp Hot Bulb 2 cylinder.
I'm from the 🇺🇲.. we have an old cotton gin and it has a fairbanks Moores twin in back. Hasn't run in what looks like 40yrs. But I always wondered what it looked like running.. and this video here answered questions for me.. thank you sir for this amazing post.
@@ActrightYT it's like dodge offering the hell cat hemi in everything, it may be complete shit (given their quality control history) but at least it's fast shit before it breaks.
@@atvheads, Diesel, gasoline, kerosene, vegetable oil, canola oil, waste engine oil, rubbing alcohol, olive oil, and anything else flammable. If it’s a liquid and it burns, the engine will run.
Now this is ⚠" Caution rotating equipment. Keep all loose clothing away" type machine right here lol imagine getting sucked into that rotating assembly. Yikes, love it. Back when Men were Men
Yea pretty much, you just have to hold the injection pump so it doesn't fire, wait for the engine to stall out and before the engine looses all momentum, you fire the injection pump manually at the right time and it'll fire and run the opposite way if done properly.
I've watched a few of your vids and read that they run on "crude-oil" ... what do you mean by that? Diesel? Kerozene? or something else? My guess is that it runs on what we call "gasoil" (what is used for central heating) and not on "heavy fuel" as there is no fuel-"pre-heater"-system.
Hi! Crude oil was like diesel but lot thicker and full of sulfur and not very clean. Therefor very chep and economical. These engines can run on pure waste oil, fish oil, vegetable oil. Really anything that is a liquid and burns if heated. The hot bulb in the cylinderhead is pre-heated and keeps hot and makes the oil to a vapour when the injector sprays. So not kerosene or anything like that. Very thick oils is what it is made for. I run them on diesel, just because it produces less carbon inside the engine compared to oils. Hope this was what you wanted to know! /Richard
@@YesterdaysMachinery yep. Thank you. I remember an uncle, living in Congo in the 50ies/60ies, telling me that they made their engines run on palm-oil when diesel was not available. But they had to "pre-heat" the oil to make it more "fluid" to pass the injectors. Hence my question.
It is made in Sweden in the late 30's. It is on 35hp and weighs over 3000kg. The piston is the size of an 10 gallon bucket. An expensive and rare engine here in Sweden. Im glad to own it.
Etwas weniger wackeln wäre nicht schlecht, sonst schönes Video. Zweitakter, klar. Aber wie genau funktioniert der hier, hat das was mit dem Kessel auf dem Zylinder zu tun?
@@rcflo7300 Dafür ist er viel zu groß. Ich kann mir nur vorstellen, daß der Kolben bei der Abwärtsbewegung, also dem Arbeitstakt, Luft in diesen Kessel drückt, mit der das Abgas dann aus dem Zylinder gedrückt, also der Zylinder „gespült“ und mit frischer Luft gefüllt wird. Das würde passieren, kurz bevor der Kolben den unteren Totpunkt erreicht hat, weil der Kolben dann den sog. Überströmkanal freigibt.....
Ja, der große Behälter am Zylinder ist für den Kraftstoff. Es läuft mit Rohöl. Der kleine Behälter ist das Schmieröl, in dem der Motor geschmiert wird.
@@YesterdaysMachinery Ahja, das habe ich jetzt auch gesehen, kommt ja die Kraftstoffleitung oben von dem Kessel. Aber wo saugt er Frischluft an, wo wird sie vorverdichtet und wie kommt sie in den Zylinder? Gibt es eine Funktionsanimation zu dieser Motortype?
Gosh I like this engine. It would probably run a 25 kw generator easily. Just don't know how to keep the revs at 50 or 60 cycles because I would be willing to bet it's governor would not be up to the job. Probably have to build a ball flyweight for throttle control.
Actually the engine runs at 315 rpm that is not fast enough. In order to make 60 Hz you would need a 24 pole generator and run it at 300 rpm, but they are few and far between. If you could find one it would sound great. I use an old Onan 4 pole generator and it runs at 1800 rpm. Standard modern gens are two pole and run at 3600rpm and sound noisy and angry. You would have to find an old 24 pole sync motor and run it as a generator. Could be done and it would be cool.😉
@@MatthewBerginGarage no, do you see those flywheels? What you do is run 2 or 3 fat v-belts straight off the flywheels gearing it up to 1,800 rpm easily from even lower rpm than 300. You could probably run it from 200 to 250. I will calculate and tell you what size v-belt pully is needed on the generator head. A month ago we had 120° here and it killed half my queen honey bees and now it is getting hot again so I will stretch a shade tarp over my other bees.
@@MatthewBerginGarage In calculating it out it seems a pulley on the generator head could be 5.15" on the generator head which would turn the genset at 1825 rpm without slip but with slip it would be near 1800rpm. That is if the flywheels are 3.5'. Of course you folks are probably metric then I would probably have to convert it. In college classes back in the 60's I used metric all time but I am 74 and have to convert it.
@@PaulHigginbothamSr Good idea but using pulleys to increase the speed will also amplify any rpm variations which will make it near impossible to keep the system on frequency. Belts also won't work as there can be no slip, so it would need to be chains or gears. 🤷♂️☹ It is preferable in this case to use a 24 pole synchronous motor as the generator because the sync motor operates close to the engine's natural rpm and the extra rotating mass of the sync motor will aid in the stability of the system
No, very little. I have a simular engine in my big old sawmill from 1948. Also a 35hp Swedish made hot-bulb from the late 30's and that one used around 4-5 liters of diesel every hour if i really work hard in the sawmill constant sawing big logs. And you can run it on diesel, waste oil, vegetable oil, crude oil, melasses and practicly anything that burns and floats. And the realyability is outstanding. Big and a bit hard to move around but very good for work. This one weights over 3000kg..
No, i run them on old poor quality diesel that i get for free from farmers that they dont want to pour in to their 2020 John Deer tractors. There is a oil-loss lubrication system for bearings and cylinder, so it uses a little bit of oil to lubricate, but not much. Maybe like 1 liter/12h.
