- Produced by the U.S. Navy during WWII, this black & white training film explains the construction and operation of diesel engines, primarily through a series of animated diagrams. The film examines a generic type of diesel engine (probably one built by Fairbanks Morse for use on submairines), noting that while there are differences in design, they all share the same fundamentals in terms of construction and operation. Copyright 1942, and made by Audio Productions. Note: A related film can be seen at: • SUBMARINE DIESEL ENGIN...
Opening titles: The Construction of Diesel Engines, U.S. Submarine Base in New London, CT (:06-:27). Engine frame of a diesel engine. Cylinder jacket, cylinder liner and the cylinder head make up the engine. The parts are explained and discussed by a narrator. Crank and cam shafts are shown and explained (:28-2:14). Scavenge ports. Exhaust ports explained. Cylinder heads and piston rods (2:15-3:14). Title: Frame Types. "A" frame construction, crankcase construction, en bloc construction types are shown and explained. Stay-bolt construction (3:15-4:34). Title: Cylinders. A cylinder is shown and explained. Dry liner and then the wet liner are explained. Two stroke cycle engine. Opposed piston engine. Four stroke cycle engine (4:35-6:30). Title: Pistons. Different pistons are shown. Pistons are made of cast iron or forged steel. Pistons top is crown, lower is skirt. Inside a piston is shown and explained. Double acting engine. Piston is made in three sections, a hand points at it with a pencil. Cooling oil are in a double acting engine (6:31-8:12). Title: Piston Rings. Piston rings help seal. Compression and oil are two types of rings. Piston rings are made of cast iron or forged steel. A steel band helps with increased strength. A ring is shown as a hand points at it. Ring joints. Oil control rings have two functions which are explained (8:13-9:59). Title: Connecting rods. Rods are shown and putting something in them is explained. A bolt is screwed on. How connecting rods work is shown in animation and in reality (10:00-11:24). Title: Crank Shaft. How the crankshaft works is shown. Crank webs and crank pins. The crankshaft turns. In an inline engine, there is a separate crank for each cylinder. In a "V" type, there is one crank pin journal. Pistons evenly distributed (11:25-13:18). Title: Bearings. They are made in halves. A bearing is scraped. Pieces are placed into a bearing (13:19-14:05). Title: Camshaft. Camshaft is made of high grade steel. A camshaft turns. Camshaft controls the timing of the engine (14:06-14:45). Title: Rocker-Lever Assembly. It's purpose is explained and shown with a real rocker-lever. Diagram explains in more detail. A diesel engine (14:46-15:47). End credits (15:48-15:54)

Excellent production /graphics for the 1940s! Also, props to the myriad engineers over time that came up with these amazing engines.
Couldn't agree more!
Excellent training video from long ago. Thanks for making it available.
A main component of every engine is the crankshaft. The name has two origins. The definition that was more obvious to me originates with the introduction of the automobile. Originally an engine was started by turning a handle attached to the crankshaft in a cranking motion "shaft turned in a cranking motion." The second definition is much older and relates to the shape. The 16th century definition is "to zig-zag", "run in a winding course", " a bend", or "a crook".
This is a great video! I especially liked the part showing the lubrication on the submarine engine. I need to find a video on the submarine engine.
Many of the US Diesel subs used OP engines made by Fairbanks-Morse. Even some of the Nuke subs had a couple of them as hotel power for when the reactors were shutdown. And I have worked on/operated some in stationary use. They are an interesting engine.
I don’t think that you have lived until you have heard a supercharged two stoke opposing piston Diesel engine. Stirring stuff.
Napier Deltic has an amazing sound too.
The engine room at the US Navy training facility in Great Lakes had a dozen running diesels and one non running gas turbine. One of the engines was a huge Fairbanks Morse opposed piston from a YTB. The cylinders were large enough to stand in. I only heard it run once. In reality, you more felt it in your bones than heard it. Incredible machine.
Super excellent! Great upload!
Great stuff...so much better than documentaries made in the 21st century. Wish it could be expanded to cover the design concerns and trade-offs of major components.
I'm more surprised about how he pronounced "alloys". I would put the emphasis on the first part but he put the emphasis on the last part.
Even though they are speaking English and not German I still found this interesting 🤔.
I wish they made training videos this good now.
I'll never forget my gf in the 80's having a little VW Rabbit Diesel. I was so impressed with the 55-60 mpg the little car had. Hers had an optional sunroof. I don't think the car was very powerful, but it was sure easy on the pocketbook.
My friends a couple had a beige one. Not very quick but cheaper than s to run. You'd have to wait for the glow plug to warm up before you could start it. After that it smelled like any diesel - Kenworth, Mack - I liked the smell myself. 🚗
@@cuda426hemi I was so in love with that blue eyed dirty blond that I could care less about anything else. She was a business woman and knew how to cut costs. She wanted a prenup, I protested and that ended our relationship. She could take that Rabbit and shove it where the sun don't shine. I've got my Mercedes.
Those Small VW diesels were very fuel efficient. That was an advantage...But the parts and equipment that were needed to keep one running, when they got close to their expected service life (and in the case of the 1.5 L engines, unexpected service life) were expensive, and hard to find...That, and their extremely low power output, were probably the main reasons they aren't seen that much anymore. The owners of cars with the 11mm head bolts, found that the aluminum heads (that actually were originally designed for gas engines), warped quite easily when the heat that diesels are known to generate, started building up and then annealed and softened the aluminum, then warped the castings and started blowing head gaskets... These engines were much like the late 70's GM diesel V-8's that were basically gas converted to run on diesel fuel ... Not reliable at all... Great - while they were working, not so easy to repair, and very expensive - and a real headache, when they stopped working.
You remember the car more than her ? 😆.
Take that engine, add a cylinder and it's an Audi, add another and its a Volvo. Most of the internal parts are the same. I still have the injector pump timing tools kicking around.
Outstanding!
Excellent video, well made
Awesome Treasure Thanks 😊 👍🍟
Goodnight all
It seems somewhat strange that the Bureau of Aeronautics (BuAer) gets the final credit in this interesting film. I thought that only the rigid-frame (Zeppelin-type) airships (Los Angeles, Macon, Akron, Shenandoah) would have used Diesel powerplants, and they were all gone long before 1942.
A classmates of mine father was a commercial fisherman a scallop dragger on the NJ coast.
He pulled up a lot of strange things including a airplane with pilot and mistress.
He also pulled up the German diesel from one of the Navy airships that crashed off the coast.
He was a WWII PT boat mechanic that drove a diesel Mercedes’ so he recognized what it was rare as they were.
He wanted to give it to a museum
But I never heard where it went.
20 years later sport divers found the wreck and claimed no one had seen anything of the airship since the 1930’s.
Close your eyes, and the intro sounds like a Warner bros bugs bunny cartoon. Coincidence?
It was tge style for the time. Triumphant and cheerful. And tge videos are simple clear and use real models to illustrate the concept and actual design. Brilliant.
Possibly the same orchestra. I had to laugh at the intro music - imagining the studio music department being asked to arrange a score that would "convey the excitement of diesel engines."
Now I'm cranky
That can mess up timing treat it with proper amount of cheep booze immediately.

Side note: Subs are boats not ships - they have no keel hence the name Electric Boat - the co. that makes Subs across the river from New London in Groton CT. Subs were/are hybrid EVs - now they are steam powered from nuke reactors but our WWII boats used diesels on surface to charge the batteries for underwater propulsion. 🛶
You're allowed to call a ship a boat only if you are a member of the crew.
"She's a good boat."
"I hate this damn boat."
Some of the nukes still had/have a Diesel engine for hotel power. Ohio Class subs had 1 F-M OP engine to drive the Aux generator when the reactors are shutdown.
@@gravelydon7072 Boomers - soon to be retired for a possible new class- smaller of course. When I saw the first Ohio class floating up the river in Groton (my old home town) it was ridiculously huge - 3 city blocks; made the old Nautilus docked there look like a dingy. And they weren't even as big as the Russian Typhoon and Borei class!! 🎸
