Truck Shop Posted October 17, 2017 Share Posted October 17, 2017 A discussion came up at work about odd engines and I tried to explain the Deltic and ended up using this cutaway pic which did a much better job. Saw one this last summer loaded on a drop deck headed for port of Seattle. First and only one I've seen.

Probably way ahead of its time, but gives me a headache just looking at it!

1958 F.W.D. Posted October 18, 2017 Share Posted October 18, 2017 (edited) The FDNY's Mack Superpumper's main pump was driven by a 1400HP Napier-Deltic Engine which drove a DeLaval three stage pump, 8800gpm at 400psi or 4400 gpm at 700psi. I have seen one of the engine manuals in the archives at the Mack museum. Also, a gentleman on Long Island, NY purchased the spare engine that FDNY had on hand through an auction site. He advertises it for sale occasionally but of course wants some kind of astronomical amount for it. https://firematic.com/napier_deltic.htm Edited October 18, 2017 by 1958 F.W.D.

I looked on youtube and couldn't find any of it in action.

There are very few videos of it pumping in existence. What is out there are mainly converted 8mm movie reels. There is a video of the Super Tender's Intelligiant Deluge Gun (capable of 5000gpm) being fed by three or four pumpers at a muster in California about 10 years ago. If you are interested in the Super Pumper System, I highly recommend the book "The FDNY Super Pumper System" By Jack Calderone (FDNY Battalion Chief, Ret.) published by Fire Apparatus Journal publishing. Tons of information and lots of fantastic b & w and color pics 1 Quote TWO STROKES ARE FOR GARDEN TOOLS Link to comment https://www.bigmacktrucks.com/topic/51408-napier-deltic/#findComment-382841 Share on other sites More sharing options...
HeavyGunner Posted October 18, 2017 Share Posted October 18, 2017 In the cut away pic above the number 19 there is a bunch of square openings. Are they part of the cylinder? If so does that mean it’s a 2 stroke?
