bolinder eskilstuna hotbulb semi diesel engine

[Tjita1]

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! 

[daand12]

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

[martijnbaarn]

you are right , it's running the wrong direction all the time .

the oilpump works both directions , so it doesn't matter that much .

[Grandpaaaa]

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) :).

Had deze ook koeling nodig?

[martijnbaarn]

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 .

what an awesome engine that is. What applications would this motor be good for?

[martijnbaarn]

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 .

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

If its a 2 stroke and crank case scavanged how do you lubricate the cylinder bore and bearings?

[martijnbaarn]

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 .

[northerbrewer]

Very interesting:

So what is the oil type and consumption?

What is the bore, stroke and compression ratio of this engine?

[martijnbaarn]

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 .

Is that a reed valve under those holes in the crackcase ?

[martijnbaarn]

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 .

[bugsier5]

loopt wel een beetje snel!, kan volgens mij veel langzamer zo'n Bolinder !

[martijnbaarn]

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 ...

[bugsier5]

blijft een mooi karretje!!

[martijnbaarn]

dank je ! je kan hem in t echt zien op het historisch festival in vreeland 15 en 16 augustus 2009

[Cmdevin]

zit het niet in je regulateur? ik heb een W3 (dit is denk ik een w7) maar die van mij loopt veel langzamer, ook als ie koud is. ik zal binnenkort een filmpje plaatsen! maar mooie motor!

[SthealthRaider]

bolness of bolinder?

[sheps999]

Is this a 2 stroke?

[martijnbaarn]

yes this a 2 stroke engine

[geoff390]

HEy nice engine. What was the thing you see spinning at 2:36

[martijnbaarn]

that's the oil pump used for engine lubrication

[martijnbaarn]

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.

[HunsV]

Do you know what this was originally used for?
