Big single pot diesels

[magnetman]

I fancy fitting a 'one lunger' in my boat. The Gardner 1L2 and RN dm1 are too small, the Kelvin K1 should be big enough 147ft lbs torque but very expensive i expect and there's only the one available i think Are there any other 'full diesel' marine single cylinder engines which would do the job?

Crossleys made a 'bigger single', the BW1, about 15 to 20 bhp depending on configuration, rpm etc.

Although marine BWs were made, down to 2-cyl, I don't think they ever made a marine version of the single.

Spares are almost non-existent.

If you can find one and if you take a mortgage out one of these perhaps

or this one if the link will work

I though porn was not allowed on here.

 

What's with the flywheel guard? is it a guard? if so why doesn't it cover the whole thing?

Mmmmmmmm......... engine porn.................. mmmmmmmmmmmmm

 

Kevin Whittle has a 15hp bolinder for sale - second mortgage time!

 

What about 22hp at 440

Ah just noticed - you want a full diesel - not semi.

 

The K1's probably about the most practical (spares etc), large single lunger out there. 155 ft lb - probably wont be beaten

I agree - that K1 is a lovely thing and you could put a decent prop on it. You've seen what a 'three lunger' looks like - just imagine having an engine that you can walk round and oil up without having to bend down. And just think of all the fires you can light with the used cotton waste

 

 

It would be worth putting a bid in because although it will not be cheap, the state of the economy etc. at the moment means that there may never be a better time to buy it . . .

And most important Kelvins were made for boats in the north sea not like some of the infereior grey standby light house generator engines adapted for boats

Ouch Denis - run for the fallout shelter!

 

A lot of Kelvins were also fitted in lighthouse's. Most can be found under the sea next to the lighthouse. When they were replaced they were thrown of the edge of the cliff .

 

Back to MM's topic. I've racked by brain and, all of the single cylinder full diesels I can think of are around the 10hp mark and chuntering on between 1200 to 1500 rpm.

 

Knowing MM's boat - he needs a bit of torque and an ample prop.

 

There may be some mainland Europe stuff? Dutch/German/Swedish?

You are quite right the bigger Kelvins were intended for seagoing duty and the petrol start on the J and K series proved helpful when starting in the extreme cold conditions that these vessels were expected to encounter. Nevertheless, the K2 and K3 engines used to drive the air compressors coupled to fog horns at lighthouses around the Scottish coasts were identical to the full marine version except that they were coupled to a compressor rather than a gearbox. The grey engines used to drive electric generators were Lister/Blackstone JP3 and JP4 units.

 

Our engine was originally installed in the Thames sailing barge 'Dannebrog'. She was a ketch barge of 71 tons built in 1901, by McLearon at Harwich. The K3 was supplied new and fitted by Richard's Iron Works at Lowestoft in 1955 but it replaced an earlier identical engine that had been fitted to the barge before the Second World War. We know that the barge carried grain in and out of Ipswitch and was later used by Taylor Woodrow in 1974 during the building of St. Katherine's Dock where she later became a static exhibit.

 

Although the J and K series (built to full marine spec) would have been far too expensive to fit to narrowboats, during the early part of the twentieth century, the Great Central Railway (later LNER) fitted small Kelvin petrol engines to some of the boats that it used on the canals around Macclesfield, Stockport and Ashton.

OIRO £10k for the K1 apparently. Nice engine. 21bhp@750rpm. £10,000. Nice engine Nice bit of dosh too.

[blueprince]

I know Lister made some, I've seen one used for a household supply in S.A. and given some of the prices it might be worth importing. The size seemed compatible with a NB though thats about it. HUGE flywheel and a hand crank start!

[Jacq]

Could the brass flywheel guard be to stop oil spraying off ?

 

Re: the Kromhout, it arrived at my house yesterday! Should be fun latter in the year.

[magnetman]

Blueprince, i think you're talking about the Lister CS, originally used to power startomatic generators and corn grinders and things. Two massive flywheels. They come up on ebay, not much money, and people do veg oil experiments with them. Not really big enough in terms of torque i don't think.?

The JP2 was originally known as something like a CS 21/2 (21 bhp, 2 cylinders) and is basically a 2-cyl version of those engines with one or two 'sophistications' such as internal pushrods. Older 'JPs' have CS engine numbers, the JP designation came in during WWII and stands for 'Joint Products' after Listers combined forces with Rustons who produced a very similar engine.

It is to stop the oil escaping from the front bearing from being thrown around the engine room.

It started with a thin piece of tin then developed into decoration.

 

If it comes all the way it will interfer with the starting pin.

 

And of course you will not be able to see the shiny flywheel which many boat kids would have polished whilst motoring with a piece of sand paper.

 

I also have a guard by the rear bearings on mine although I was told by the late Chris Lloyd that the guard on Stour was to stop the cat getting caught in the motion. I disagree as it was clearly to stop oil splashing across the engine 'ole floor.

 

I think the 'photo is of Stour any more info ?

Do - tell. What are the plans?

[Jacq]

The plan is to put it in my Northwich Trader over the winter.Should be fun as its such a tight fit, i just hope my measurements are right!! At the moment im trying to gather as much info on 2 stroke diesels in relation to the exhaust / expansion box , as it would make life easier if i could fabricate a different one.

'It' being, exactly?

 

Reading between the lines some sort of monster Kromhout?

[Jacq]

The one in the link futher up. It can be seen running in its origional boat if you search youtube for "Kromhout type M1"

Sorry if this has wandered off the origional topic.

[magnetman]

Sounds like a cool engine, what is the power output/rpm? When you say 2 stroke diesel this is a semi diesel i assume with a hotbulb system.

[Jacq]

Its 22hp at 440 rpm. Yes its hot bulb. 2 stroke, so no rocker valves , reed valves like a 2 stroke motorbike.

[magnetman]

I was once told there are 2 stroke 'non hotbulb' diesels for example 'Stuart' and 'Detroit' and possibly 'Hanomag', and there's something about 'Rootes blowers' for scavenging? is that right? It was a long time ago it was explained to me. Widdop?

[Jacq]

Im not sure about those names. Ive come across reference to the scavenging effect to do with the exhaust system.

If you fancy a smaller hot bulb i may be able to point you in the right direction (9 hp.)

There are 2-stroke diesels still in production, Detroit being the best known.

Foden, Stuart, Turner (not the Stuart-Turner Turner), Rootes (Commer), Crossley, Petter have all made them in the past. The blower you're thinking of is Roots without the 'e'.

Widdop made diesel and hot-bulb versions of the same engine, they were crankcase-scavenged like the Bolinders, Petters, Kromhout etc semi-diesels. The Crossleys used what was basically an enormous bicycle pump for scavenging.

 

I've got a 12hp Sabb semi-diesel, crankcase scavenged but quite modern made in the 1960s. Unfortunately it was built, like many scandinavian semis, for a variable pitch/reversing propellor, which I don't have & haven't yet found one 'spare'. Yes, I could fit a gearbox but it would spoil the fun a bit.
