Its really amazing to see it from the back, and to realize how close your hands were to all those moving parts, while the whole thing was bouncing like crazy. Amazing work bringing that beast back to life.
Not quite as exciting as your runaway video, but it's impressive how something that old can still function, and equally impressive that someone knows how to make it function. Great Video!
That is a piece of Norwegian Marine engine history .No new engine would ever live trough the abuse this engine has been trough and be able to keep running as smooth as this engine does
I love those old engines, how they look, and sound. My grandmother said that when she was growing up before the house got electricity they had an little engine they moved around to power the pump for the well, the washing machine, some tools and other equipment around the house and shed and barn including a generator. She said that they got electricity in 1956 but did not really use it until 1960 because it was "not dependable" & to expensive. They put electric lights in the house in 1963.
That is one of the skills you have to master when dealing with these old irons. It is not uncommon that they start backwards and they may also change direction by themself if you let them run too slow. They may even run back and forth about 90% of one revolution for a long time...
You partly see the glow element at 9:26 at the rear top of the cylinder head below the flame shield. It is pre heated for 5-10 minutes using propane or a diesel burner. Also note the handle on the injection nozzle: For idle or low power running, the nozzle spreads the diesel in the fore chamber but on high load the engine would run too hot and the nozzle is adjusted to send the diesel thru the fore chamber directly into the main combustion chamber. I believe the compression is about 6:1.
***** Well, not really. As a two stroke engine, it may run well in both directions but this one is dependent of going the right way due to the design of the crank lubrication system.
@@jetstream454 It happend to start in the wrong direcion, which will happen every now and then, and one of the skills needed to operate these engines are to change the direction.
Really cool, especially the reverse direction on the fly.In the seventies we were on a sailboat and sailed to a small island called Tabaca 11 miles from Alicante Spain. we were staying the night at the small stone dock and we heard a couple of fishing boats coming to the island, they had similar engines . We heard them coming , donk, donk donk, for about half an hour across the flat water, they finally showed up and after stopping them crushing us by coming alongside out little 30' sailboat, they tied up and unloaded their catch and then went ashore to their family, but they left the engines slowly donking away all night! They never shut them down! next day they were off again , they only came back once or twice a week!Amazing engines.
That engine runs great. 2 stroker like the Lanz Bulldog which also could run the reverse way. Only problem is that the oil pump didn't do its job and risk of seizing the engine was a possibility. Great video.
Love how it sounds. Sounds just like a tug boat tugging along. I think it's the type of engine that will just about run on any kind of fuel if memory serves me right and they're not very efficient. But they did produce alot of torque and they got the job done.
Take a close look at 1:10 and you will see that it takes almost one revolution in the right direction and so starts to run backwards. Around 3:00 I slow it down almost to stop and give it a couple of manual fuel injections slightly before TDC to change it to correct direction.
That is just a buffertank for start-air. The yellow hose coming from the right side supplies air at 6-6.5 bar which is quite a bit on the low side for starting this engine. The tank is a buffer so that we get as much air as possible in a short time to get the engine spinning as fast as possible for start.
10 litres of water in the crank case?. I figured it would at least have the essential bits covered up!. that makes things even cooler that it can run after 2 years uncovered!
Yes, that makes sense... But then air filter would get very black, very soon :) Anyway, great video, and cool engine. Keep updating your progress, I'd like to see where will that engine end! :)
@MyNameIsAwes0me Hit&Miss is only one primitive way to control the rpm and is used both on old petrol and semidiesel engines. In a diesel engine, the compression temperature is high enough to ignite the injected diesel but in a semidiesel, where the compression might be something like 4:1, the compression temperature is too low and there are a glow plug that ignites the diesel when the diesel hits the plug.
Our next to last snowsled had the same way of reversing. Twin, 2 stroke gasoline engine, no reverse in gearbox. Instead, when at idle, we just pressed an electric switch for a moment, et voila! Engine started running in reverse. Same procedure to go forward again. I guess that switch only moved the timing of the spark. An elegant way of dispensing with the complication and added weigth of reverse gearing. But unbreliable. Was very dependent on that timing shift beeing spot on, and I guess also on correct idle rpm.
First time I seen this video and knew I had seen this engine before. This is what happened 2 year either, lol you are a brave man. Rap 24 hp semidiesel, second start attempt.
@SveinHaDD The glowplug might be electric on newer engines but on older engines it is a steel thing that have to be heated with a blow-torch prior to starting. With the engine running, the glowplug maintains sufficient heat due to combustion temperature.
"The engine started running backwards and at time 3:00, I reduce the rpm and give it a couple of manual fuel injections to change direction to forward." But wasn't it running backwards from 1:10 to 3 minutes and after that it was running the correct direction through the rest of the video?
The windows is to visually check and adjust the lubrication of the engine. There are six channels feeding oil to various parts of the engine and from the bent tubes in the window, you should see and count number of drops of oil per minute. No fear of explosion but if the rpm had increased quite a bit more than i video #2 it may very well have self-destructed and it would not be very nice to be close to it...
kind of, except it requires no electricity once the engine is running. the heat of the combustion process is stored in the glow element (glow plug) and it stays red hot throughout the next intake/exhaust and compression cycles of the engine, where it assists the engine in igniting the fuel which heats it up again, and the cycle continues!
Oughta give the old girl something to do. Back then these engines run almost 24/7, low RPM applications. Feed her biodiesel and belt her up to run a sump or vent fan or something non-safety critical :)
Yes, but I was confused that engine could run backwards at all. Then i guess it must be a two stroke diesel? Right? Because on four-stroke, valves would open and close at wrong times and couldn't work.
I never had one self destruct but the vibration has made them fall over and spin around the ground on the flywheels. Very funny to watch but quite dangerous to stop.
I want one of these to put in a little boat or vehicle . I would be the happiest man alive! Unfortunately, they weren't made nor imported in my country :(
A diesel engine ignites the fuel by compression temperature only but a semi diesel (or half diesel if you like) needs a glow element i addition to compression temperature.
@cambriacity Still working on it. All brass parts removed and ready for sand blasting. Low priority project so it will take some time. Stored indoors at present.
6:1 is very low! Impressive! It's about 1/3 of a normally aspirated gasoline engine! That explains the need of a glow plug; without it, the diesel would not bang, because of insufficient compression (in order to self ignite): is that right?
Combustion air is pumped in to the combustion chamber thru the crankcase. There was too much lubrication oil in the crankcase and the oil was drawn in with the air... Not a very uncommon happening with these engines and quite a few boats have been shaken to pieces and sunk following a major runout.
@cambriacity At this time, nothing. Normally, there should be direct sea water cooling. Without cooling, this 8-9 minutes run is about max without overheating the engine.
Where exactly does the glow element sit? Does the engine have a fore chamber (probably yes, since direct injected diesel are a high tech invention of these last 10 - 15 years)? I guess that the advantage of such an engine is to run fully autarch once it has been started... without any electrical source, so to speak! Probably the compression is almost at the level of a gas engine!
Se on vain puskurisäiliö alkavien ilmaa.Keltainen letku tulee oikealta puolelta syöttää ilmaa 6-6,5 bar puulattia hieman liian alhaisilta käynnistykseen tätä moottoria. Säiliö on puskuri, jotta voimme saada niin paljon ilmaa kuin mahdollista lyhyessä ajassa saada moottorin pyörivät niin nopeasti kuin mahdollista aloittaa.
+TechnoDelta This kind of engine was widely uset for ship propulsion in several decades in the 20th century. It's now mostly for fun but also to preserve a part of history. It is now refurbished and looks almost like new but we haven't been able to make a new video. Hopefully we will manage this summer...
It have been completely visually refurbished but still not started. It is located on a small island (Litle Kvartnesholmen) close to the Norwegian coastline and should be used just for fun/museum.

Ya 24 hp but 1000 ft lbs of torque! Very cool . Glad to see people are passionate about old world tech. Got to love the injection set up too. Simple.
Naturally its perfect for a go kart
Okay maybe a tractor of some sort lol
Like a big rusty heart. Amazing!
runs a lot better when it's not trying to run on it's own oil..lol

if you put modern engine outside, it will never run again, this proves old is good and made to last

A rolling stone gathers no moss ,but on a spinning flywheel!
Old school stuff is the best!

The "third guy" does a really good job of "standing and watching."
A vital task.
What an amazing engine, I salute from Argentina (sorry for my bad english)

This kind of engine was widely used for ship propulsion in about half of the last century.
I see what apears to be Co2 Fire extinguisher in the foreground.
Good thinking, and I hope you never have to snuff out a runaway with it.

Right! First thing I thought when it loaded up - "Oh look, someone finally learned the easy way to deal with runaway diesels"
She runs in both directions!

Great stuff!, I wondered what happened to that crazy thing!. looks like it hadn't gone far since the runaway :D
Sounds wonderful now.
Well done. Also nice good hd camera too.
im love diesel's since i was born,now i know why

We had about 6-6.5 but something around 10 bar is more common and better :-)

Definitely a ship engine, beautiful thing.
@cambriacity Still working on it. All brass parts removed and ready for sand blasting. Low priority project so it will take some time. Stored indoors at present.
My advice: fix it properly to the ground and then let's go full throttle!
Fine machine, like the sound. Built for the eternity!
Hey!! The famous runaway!
that would make a nice biofuel unit for the farm pumping power back into the grid i would have it running all time veggie4life
Did you notice, at 3:02, the engine changes direction. after 3:02, the engine sounds better, because it's turning the right side round.
@rwc297 These kind of engines were widely used for ship propulsion for many decades in the last century.
so this is what construction workers do on their coffee break :D
nice sound
Love the guy with the apple... he can't care the less apart from his apple! ;)
herlig maskin!
veit du om noko sånt som er til salgs??
It's a two-stroke but even a 4-stroke may run backwards taking in air thru the exhaust pipe and sending the exhaust out the air intake...
6:1 is very low! Impressive! It's about 1/3 of a normally aspirated gasoline engine! That explains the need of a glow plug; without it, the diesel would not bang, because of insufficient compression (in order to self ignite): is that right?
This is awesome! thank you SveinHaDD
Good to see it didn't take off again like the last video. What caused it to start revving fast like it did and pushing you guys around?
Combustion air is pumped in to the combustion chamber thru the crankcase. There was too much lubrication oil in the crankcase and the oil was drawn in with the air... Not a very uncommon happening with these engines and quite a few boats have been shaken to pieces and sunk following a major runout.
Hold on, has that blue cargo container on the left been converted into a shed? If so, that's really cool.
3:01 - Is that me, or did the engine changed rotation direction!? :O
gotta have one of those for a home backup generator. would need a bit of silencing tho i would imagine.
+ben hunter
Bit different animal than your typical modern type example of engineered obsolescence.
What would this have been used for? An electric generator or something?
How about the cooling? No load, but hopefully at least the jacket is filled with water?
No need for cooling for such a short run.
@thebrassmonkey100 no worries ;)
Beautiful tickover. What did this engine come out of? Boat?
nice ear protection!
@cambriacity At this time, nothing. Normally, there should be direct sea water cooling. Without cooling, this 8-9 minutes run is about max without overheating the engine.
Nice engine, but with wicked character....
But why is it called SEMI-diesel?
Interesting how one eccentric drives three pumps.
Monster!
AMAZING!!!!

Probably the compression is almost at the level of a gas engine!
what was this engine's original purpose? also, do you have to add oil premix or does the diesel fuel provide enough lubrication? thanks!!
The rpm is pretty low. Sounds like the old engines used on boats. When in perfect condition could it have a much higher RPM?
It's sound is like an old alco locomotive from 1950s 😄
PUUURRRRRRRRR!!
How did it turn the prop, with a belt?
something is wrong... its not shaking its self to bits!?
Hey =) Whats the displacement on these? At a guess i'd say 2000cc or 2 litre's and a single cylinder?

Nice engine but it looks like he's running it with no cooling water!
my question is what was it used for, and what is it going to be used for? or just a fun project?

Any video yet? Would be nice to see it fixed up :)
Where is ours video m8?
any pictures atleast?
our s stroke weed eater does that when it is started it goes one way then turns other way and it eventually starts
is a semidiesel kinda like a hit/miss petrol engine?
No joke i have seen one of these with a turbo
@jack9102 Yes,it is a hot bulb engine and it run on diesel (instead of what?)
That a Duramax or a Powerstroke?
Part 4 coming soon?
they need kind of a Spark plug, so to speak, is that what you mean?
Is it just me or did it change directions at 3:00?
Does the smoke happen cause the engine is old or just cold
jonas martin
Insufficient air in fuel mixture
Osama I thanks
So how is it running now... About four years after oh and happy new year
It have been completely visually refurbished but still not started. It is located on a small island (Litle Kvartnesholmen) close to the Norwegian coastline and should be used just for fun/museum.
Svein Hauge can you make new video from this engines new life? :)
age?
