Hello, sorry I didn't see this until now. That's a very nice example of an early MAN.

It’s a shame that these engines don't get the recognition they deserve. If it weren't for these, engines today would be very different.

يبدأ بالهواء المضغوط.

It's a nice beat in 3/4 or 6/8 time.

Because it is. Fuel system is a bit dodgy.

Yep. I love it.

Maximum speed is around 220 revolutions per minute, which is what it makes its peak power at (250 horsepower).

It's getting an outdoor exhaust, but it just hasn't been put in place yet.

I'm not sure if they'll have it operational (it may possibly be beyond repair), but my guess at the output voltage would be somewhere higher than 400 V AC. The engine originally had a DC generator which is not known to survive.

So do I, but we haven't any room in the shed!

Dodgy fuel system that requires a bit of further tweaking.

Me too.

Yes they have, and they’re in the process of doing it.

I don't know if that Southern Cross actually runs or not (I've never seen it run). It might as well just be a display piece.

Poor Greta would be balling her eyes out upon seeing this beast running. 😂

ومن الجميل أن نعرف أن العديد من هذه المحركات القديمة لا تزال قيد الاستخدام اليوم.

Granted that it gets looked after, it will for sure.

The bore × stroke of the engine is 381 mm (15 in) × 559 mm (22 in). Very curious to hear about your similar engines.

@@Wh4tTh3H3y Thank you for your quick reply. The two I have are Built here in England. Both are Mirrlees Bickerton and Day engines. One is a 55hp single cylinder and the other is a 180hp 4 cylinder both are air blast injection, post first world war.

Oh, yes, and this would be an interesting video to comment it on! Times have flown.

To me, it seems like the cylinder next to the flywheel is the one that backfires a few times in the video, but I suppose it just differs from different perspectives.

It's getting one. It just hadn't been fitted yet when I filmed this.

This was back when I used shake control, which I’ve given up on since everything appears all wavy.

Mostrei tudo claramente visível no motor, então não vejo o que poderia ter perdido.

Not necessarily "rich" as it's a diesel, but rather a bit of a dodgy fuel system that needs further work.

It's all about the torque, there's a good analogy that says "it's like hitting a wall, horse power is how fast you hit it and torque is how far you push the wall back". 👍👍

@@Antony_Jenner that’s a great analog, I’ll remember that one

It would be interesting if that were actually the case. The Willans engine at Scoresby is the only known running example.

Thanks for watching!

Gotta love a good old cold start.

If, by that, you mean the exhaust, it hasn't been directed outside yet.

Not yet it isn't. They hadn't fitted the outdoor pipe at the time I had filmed this.

Those 12 years of restoration definitely paid off well.

Only running on two cylinders, but it backfires a few times in the video, which could be the third cylinder firing.

I always noticed the valve order. It's the part I find the most mesmerising on big engines.

If you slow down the video and count the 4 cylinders with number 1 being closest to the flywheel, and watch the pusrods for the exhaustvalves the firing order is 1-3-4-2 like most other 4cylinder engines.

Pretty sure its a 4 cylinder. 8hr is the engine size (about 50 hp per bang) and i think the f refers to the number of cylinders.

A few things to note: - The outdoor exhaust hadn’t been fitted yet at the time I filmed this. - The Yorkshire Brewery in Collingwood is still around today and now serves as an apartment complex, but I’m not sure what beers they made back in the day. Thanks for watching.

LOL. My favourite comment.

I'm an engineer in a coal-fired powerplant in the US. I also drive a Tesla. I plug it into a free charging port in the staff parking lot at the plant, less than 100 yards from the coal pile, every day. I'd be glad to send you a picture of it! Hahaha!

That's probably the case, as the fuel system still needs further tweaking.

It is a diesel. the term "rich" does not apply to diesels - the intake air is not throttled and so there is ALWAYS an excess of air for the amount of fuel. it is running on only 2 cylinders - there is a mechanic fault either affecting compression or preventing fuel injection on one cylinder.

From what I was told, the fuel system (or one of the injectors) needed some additional tweaking. It can be seen backfiring a few times in the video, which could possibly be the third cylinder firing. I did see earlier videos of the engine running, in which is was firing on all three, but I'm not quite sure.

Would have been nice if the third leg had joined the party 😂

Watching the exhaust cams and listening makes me think the middle cylinder is laying down.

That's exactly what they were designed for.

Ein hoch interessanter Motor Unverwüstlich und absolut robust,so eine Stabilität haben die heutigen Verbrennungsmotoren nicht mehr 👍👍👍👍

Ich stimme zu!

higher demand, lets say on an alternator for example, increases resistance? harder to turn basically?

Same! I can never get enough of it. 😁

It was only running on two cylinders that day, but it still makes up for a cool beat.

@@Wh4tTh3H3y In this circumstances, I wonder if this engine is cappable of working on single cylinder ?

It probably could, but it wouldn't be very powerful.

Open-crank engines seem to be designed in such a way that the cylinder supports catch the sump oil being flung by the crankshaft. That's just my guess, I'm no expert.

​@@Wh4tTh3H3yThe engine crankcase is closed, so the oil circulates through hydraulic lines and is distributed by the oil pump. The camshaft cams run dry here and should be lubricated from the platform by an oiler. An oiler on a steamship had to service 100 lubrication points in an hour.

The crankcase is not closed

@@MrGlenferd But it has forced lubrication of the crankshaft.
