Tjita1 now I'm 28 but I've been interested in hot-bulb engines since I was 12 when I saw one operating for the first time at a stand in the backyard of the house of an uncle of my grandma. IIRC his son still owns that engine and it's under storage, maybe it would be worth to persuade the old uncle Júlio's grandson to restore that engine. Well, I'm not sure what's the exact manufacturer and model of that engine, but it looks a lot like a Mietz & Weiss that I saw at a museum 5 years ago.
Thank You for this Video, so I recognize this type of motor. 1988 I bought a very similar motor in Croatia that is full diesel and worked at that time but now it is in parts nd I want to fix it. Nice greetings from Croatia Klaus
this engine was used in a ship . this type of engine was used for numerous applications , like in small factory's , on farm tractors , and generator sets , etc ..... the main reason was the great reliability and they were easy to repair .
the cilinder and bearings are lubricated by with a small oil pump . the oil is in the little green tank (the one with the glass on it ) you can see the pump at 2:29 in the vid . the main bearings , the piston and the cilinder all have a seperate line from the pump .
the engine is designed for crude oil , irun it on diesel (gasoline ) i don't exactly know the comp/ratio , i guess it's somewhere around 8:1 really low for a diesel , but it doesn"t need a higher compression because it's an hot bulb type engine . it ignites with a hot bulb and not (like a normal diesel ) because of the higher temp caused by compression . the cilindric volume is around 244 cui or 4 liter .
this engine was fitted in an workboat . the boat was used for making the typical wooden sidewalls on our rivers and canals (in holland) i bought it from a man who had it for over 40 years (never running) he saved the engine when the ship was scrapped.
yes that is a reed valve behind the holes there is a thich piece of rubber wich works as a valve . it's not originaly made this way , but once the cranckcase exploded and the pistonrod came through the original valve cover .
Bjorneborg, maybe is Finish Pori diesel, made in Finland west coast Pori city, which is Bjorneborg in swedish. There was/is old boat motor factory. Finland is two language country. Pori-Bjorneborg
ja , toen deze motor nog in een boot zat werd hij gekoeld door het water waar ook de boot in dreef . nu heb ik het koelwater in het zwarte frame opgeslagen . het bronskleurige ding achter het vliegwiel is de waterpomp die alles rondpompt er zit ongeveer 60 liter koelwater in , daar kan de motor een kort uurtje mee draaien en dan wordt hij te heet .
Hi, by any chance do you have the workshop manual for this engine? Can It be used with diesel fuel or specifically designed for crude oil? I'd like to use one of these in a sugar cane Mill but I need to know how the cooling system works and perhaps overhaul it to some extent. Kind regards
Hello , i have no manual for this engine.but i can tell you from experience most of these will run good on modern diesel . This type of engine needs very little to just work the way it should ,even when badly worn they still go. What engine do you have exactly ?
The cooling is just simply water forced in by a pump ,temperature needs to stay on the lower side like around 60 c° celcius. The water enters the cylinder base first and goes up from there to ensure a full jacket with no air trapped inside ,from there the water enters the exhaust mantle towards the exit pipe.
and then to know that this time when the video was shot , it was the only time ever that the engine let istself start this easily . numerous other times we had to try over one hour to get it running , and believe me this flywheel throwing is a real heavy workout . thanks for your comment !
valt wel mee ,het is en blijft een tweetakt er zit ook een verstuiver in van een lanz buldog want de originele was er niet meer ,mischien dat ie daardoor ook iets anders loopt dan hoe het hoort . hij kan nog wel een stukje langzamer als ie goed warm is ...
Is the engine running in the right direction? :) Should be running clockwise (normally) when you look at it from the flywheel side. But the engine "prefer" to start at the wrong direction due to the "pre ignition". I usually let it go so for some minutes before I change the direction (or better TRY to) :).
How nice to see someone below the age of 70 being interested in these engines...

THIS IS AN INTERESTING HOT BULB ESKILTUNA ENGINE!
I LIKE HOW DID IT WORKS!

you are right , it's running the wrong direction all the time .
the oilpump works both directions , so it doesn't matter that much .

@@martijnbaarn Thank you for taking the time to reply to my questions. It's a Bolinder W7 M20 with a ground stand.
Very interesting:
So what is the oil type and consumption?
What is the bore, stroke and compression ratio of this engine?
If its a 2 stroke and crank case scavanged how do you lubricate the cylinder bore and bearings?
and then to know that this time when the video was shot , it was the only time ever that the engine let istself start this easily . numerous other times we had to try over one hour to get it running , and believe me this flywheel throwing is a real heavy workout .

Is that a reed valve under those holes in the crackcase ?
dank je ! je kan hem in t echt zien op het historisch festival in vreeland 15 en 16 augustus 2009
Hoe heb je het voor elkaar gekregen om iets van de motor opteblazen?? Hij moet nog wel lopen als het goed is, maar met veel rook
that's the oil pump used for engine lubrication
Do you know what this was originally used for?
Had deze ook koeling nodig?

Hi, do you have by any chance the workshop manual for this engine? I found one in good condition but needs some inspection before trying to fire it up
@@josedavidsuarezeljure9389 No, I don't have that.
Looking at it today it seems to be running in the "right" direction according to the position of the exhaust port. I'm learning, but slowly :)
bolness of bolinder?
yes this a 2 stroke engine
Is this a 2 stroke?
my last name is Bolinder!!
Интересно какой расход и кпд у этой штуки?
этот двигатель представляет собой дизельный двигатель мощностью 20 л.с. и потребляет очень мало дизельного топлива
how is engine cooled?
this is a watercooled engine , in this video the cooling water is in the frame benath the engine .
no radiator, do you use canal water to cool?
7 Minutes and 3 kicks :-D
A very nice engine could do with a starter motor lol
Hmm
Откуда это у меня
Я нашел это в саду
Ä
Супер👍👍👍
Отлично...знаменитый Болиндер.
спасибо они красивые дизельные двигатели
