Deltic Engines

Jan 16, 2006 27 Replies

Since I don't start my new job until the 30th both my wife and I were looking after my young son today. He was watching some trains on a TV programme so we decided to take him to NRM at York to see some really cool ones for real.



Anyway, I was looking at the Deltic there and got to thinking about the engine: is the deltic type still used in any applications today; marine, rail, generators or anything? If not, why?


nope

something to do with English Electric being no more :)

The Deltic is still used to power the Royal Navy Hunt Class minecountermeasures ships. They have 2 x Ruston-Paxman deltic 9-58K diesels developing 1900hp and 1 Deltic 9-59 diesel for pulse generation and auxiliary drive.

What a gem that thing is, but apparently it was an absolute bastard to maintain economically. Sounds better than any other IC engine though I reckon. I think tanks still use a similar concept, but could be mistaken.

Cheers.

It's a 2-stroke diesel, it makes more smoke than a coal-fired steam engine, only blue.....

Its also getting on a bit, wasn't the Deltic first run not long after WWII?

Yeah, not long after.

If you're interested!

Mmmmmmmmmmmmmmmmmmmm.........2-stroke smoke........mmmmmmm

6 railway locos still running

Rumours the prototype will restored as well

Some naval vessels

VERY expensive power unit

And a fantastic engine note - 2 D18s on full power!

It's an impressive beast alright and in the early days of big diesel engines offered a very high power to weight ratio, still impressive now at 3,300hp for a twin engined 99 ton loco. Sadly the Deltic engine hasn't been in day-to-day use in mainline railway traction for 24 years or so now, due in no small part to its horrendous complexity.

The engines sound something like a Lancaster Bomber - a very deep, almost earth-shaking, bass at idle which turns into a low-pitched howl at full power.

The Deltic Preservation Society has its maintenance base at Barrow Hill near Chesterfield , which is open most Saturdays and is well worth a visit.

This brave chap is building a miniature petrol powered version:

One application not mentioned, a New York City Fire Dept. Pumper. Used to provide power to a "high" pressure pump for sky-scraper fires.

The Super Pumper

However I was mentioning the survivors, so not including the Baby Deltics, nor PT boats, nor the 16 who were not saved :-(

Virgin used D9000 on Fridays for quite a while as they needed a 100mph Diesel

These machines have been fast enough in preservation to risk damaging a loco with a 95mph limit - known to be safe at 100mph, rumours of over 110mph

Got a bit of a crazed look to him, eh? Much respect to the man though, would love to see a radio controlled model car with that in it.

Thanks for that - I never looked it up till you posted it!

Junkers jumo diesel aiecraft engine that powered the Ju88 bomber in WW2 was the basis for the development of Deltic it being one bank of the eventual triangle. NM

So what was the engine like in the old Commer commercial vehicles, wasn't that a horizontally opposed two stroke?

Known as the TS3 - 3 cylinder lump with a Rootes blower, under the cab floor.

He needs to build another and a 7 1/4" gauge loco to keep them in
