I was a young lad in England when and where 2-stroke diesels were moderately common. Commer trucks, and even a few buses, used the noisy TS3 (based on a Sulzer design) with just one crankshaft for its OP cylinders, Foden had their own 2-stroke inline-6 that sounded like a mini-me Detroit 6L71, and I've traveled many miles behind Class 55 Deltic locos hauling 100MPH trains on the East Coast Main Line out of Kings Cross, with my head out the window, flies and soot in my hair and face, relishing every moment of it! I never rode behind a Class 23 Baby Deltic loco, but they were even louder than their big brothers. The sound of a Deltic loco at full welly is, along with a Vulcan's howl, a sound that one will NEVER forget. To help keep those memories alive, I now have a bus with a Detroit 6V92 that I've straight-piped, and that also brings a big stupid grin to my face, especially when I use its Jakes.

I worked on log skidders with 3 and 4 53 Detroits back in the 80s. I loved them. The Cats and John Deeres just wernt the same. Too quiet. We always said they were a great machine for turning perfectly good diesel into noise and smoke.

My Dad was an apprentice engineer from Canada who got his post-university training at Napier. He started in I either 1950 or 51 at 21 ro 22 years of age, and quickly found himself on the deck of the torpedo boats with Deltics recording values and helping the engine room adjust to the machines. He also worked on the Deltic locomotives, and it's a double edged sword that he was picked by the company to spearhead the Montreal office's campaign to sell the Deltic in Canada. Napier was already in some trouble and didn't provide support to close the sales Dad tried to line up, according to my Mum, focusing on UK business instead. In the end, though, the Deltic experience led to him moving to United Aircraft where he ended up working to high-power fast naval projects, as well as the Turbo Train; and after that with Bombardier where he was back to diesels, and selling the LRC. Within the engineering community, experience with the development team at Napier was revered, and made a lot of doors open for him, for decades after. As a kid, we always had a sample actual cylinder from a Deltic in the basement, an ashtray made from a Deltic piston; and a beautiful scale salesmen'a model of the 18 cylinder Deltic; any one of which I'd give a lot to have now. He only had the highest praise for the engineering talent at Napier, and said that the draftsmen could teach you more than a senior lecturer at McGill, his aima mater. And just to address those here who are suggesting that the Deltic was over complex, it wasn't. The complexity was elsewhere, in the complex power train that tied the crankshafts together, distributed power to blowers and superchargers and pumps. But an 18 cylinder engine putting out the power of a 36 cylinder unit, but without any valve trains, no heads to leak, no cooling to perform at the head was in the end far simpler. And because all those eliminated units were ones that needed frequent adjustment for timing, involved camshaft wear, rocker friction , valve seat cracking, etc. etc.... nope, this was a masterpiece of simplicity.

The Deltics are such cool engines. I spent some time in the cab of 55019 and 55022 both featured in the video. That droning sound stays with you for the entire night after a day on the footplate. But they are thoroughbred race horses, with both engines running they picked up speed very well. Some of the locomotives even had names of race horses like Alycidon and Tulyar, others had names of regiments, those in the video 55019 Royal Highland Fusilier and 55022 Royal Scots Grey. The last one was pulling a freight in the video, but they were never built for this work, they were express passenger locomotives. The owner of 55022 had it mainline certified, usually doing rail excursions, but for a year he contracted the haulage of this freight running from Blythe to Fort William in Scotland, conveying alumina for aluminium production.

My uncle used to be a fitter at BR Doncaster depot and spent a good deal of his career looking after the Deltic’s. Apparently they took a bit of looking after to keep them running well and they had a hell of an appetite for fuel but they were/are fantastic machines. Hearing one working hard is probably one of the best sounds you’ll ever hear!! I absolutely love the styling of the locomotives too, from an age where someone put some effort into making things look good!

It's actually a very simple design, as it has no valves. But that is true of any opposed piston 2-stroke diesel, like the 6 cylinder opposed piston engine it was developed from. Also, some amount of exhaust piston lead is used on all opposed piston diesels. The unique feature was making the 3-bank design work. They worked out that by reversing the bottom crankshaft each cylinder would have the exhaust piston lead the intake piston by 20 degrees. The competition were developing a 4-bank engine. The reason Napier's designs appear complex is because they were for higher power than the automotive market, thus requiring more cylinders. It's possible to build an absolutely massive 6 cylinder engine but it has to be low revving which hurts the power/weight ratio, something which was important in most applications Napier targeted.

@@londonalicante The masterstroke in the Deltic engine concept is that by adding one crankshaft, you can add two cylinder banks. You don't get that by adding a fourth crankshaft, which only gets one more cylinder bank.
@londonalicante
@londonalicante Жыл бұрын
@@andyharman3022 There's that way of looking at it. Inline opposed piston has 2 crankshafts and 1 cylinder bank, Deltic has 3 crankshafts and 3 cylinder banks (which is a massive gain for just one extra crankshaft) and 4-bank engine has 4 crankshafts (which is still 1 bank per crankshaft, the same as for 3 crankshafts.) The issue as I see it is that the 4th crankshaft and bank adds a lot of complexity as well as a lot of wasted space in the central void. According to en.wikipedia.org/wiki/Napier_Deltic the competition at Jumo did try to develop a 3-bank engine but abandoned it as they couldn't work out the timing. An advantage of the 4-bank engine is that you can have any amount of exhaust piston lead you like, but the delta configuration is fixed at 20 degrees. Here's a link to the Jumo 4-bank engine en.wikipedia.org/wiki/Junkers_Jumo_223

@@sandervanderkammen9230 No, I didn´t. The combustion chamber of a diesel has got a different shape, than a gasoline engine where the spark plug starts a fire and the flame front should spread evenly. Depending on the number of injector nozzles the optimal diesel combustion chamber meets the shape of the spraying diesel. This is difficult to achieve when there are two pistons and a cylinder, building the part of the combustion chamber. The only chance to inject the diesel is from the wall side of the cylinder - causing bad exhaust gas. We are working on large ships diesel engines with more than one injectors, depending on the size of the motor. It is extremely important to distribute the fuel precisly in order to get those very high efficiencies. And - coming along the efficiency - you don´t see any smoke at the exhauster.

Fairbanks-Morse (1) in the US who had purchased a license to build Junkers opposed diesels designed a 24 cylinder diamond layout 2 stroke diesel. It was under development for the US Navy during WWII but was abbandonded when the war ended. As usual see Old Machine Press. 1) F-M built diesels for diesel electric subs along with their own diesel locomotives.

@@stevepage2541 Blame GM for that. The TS3 & successor TS4 were all trashed by GM. Theories suggest that its much more efficient than their own Detroit Diesels and due to its small size, can fit on trucks smaller than the commercial ones. The DD and the TS3 & TS4 has functionally the same uniflow pattern yet the TS3 is much more efficient as the combustion is extracted by 2 pistons opposing each other compared to a DD using valves and 1 piston. TS3 is cheaper to make as there is no poppet valves or camshafts to deal with.

The Jumo 223 that was the immediate progenitor of the Deltic. The 223 was a prototype diesel cycle, 24 cylinder, 2 stroke, opposed piston aircraft engine. Diesel technology made leaps and bounds during WW2- primarily in Germany. Although the UK and USSR as well could see that piston powered aircraft engines were the way of the future- jet engines notwithstanding. Diesel engines are more efficient, use less fuel and the fuel itself is far less flammable. I'd guess Germany also wanted to use a fuel that was less refined that high octane aviation fuel.
