LST{Landing Ship Tank} 393 Tour Muskegon Michigan.

Take a tour of LST 393 one of the only 2 remaining World War 2 Landing Ship Tank. I concentrate on the engine room, but show the Tank Deck, soldiers bunks & wash rooms and Galley. Built in 1942 by Newport News Ship Building, It sailed until 1946. It served in the D June 6th 1944Omaha Beach Normandy Invasion as well as Sicily, Salerno. After Normandy it served in Pacific Theater. It was bought by Sand Products and renamed the "Highway 16" after a deadly two lane West Michigan highway. It hauled new automobiles from Muskegon to Milwaukee until 1970. Mothballed for about 20 years it was bought by the USS LST 393 Preservation Association as a WW2 LST It is powered by 2 Electromotive Division 12V567A 2 cycle locomotive diesels marine rated at 900HP. Each cylinder is 8.5" with a 10" stroke and has a displacement of 567 CID per cylinder for a total of 6934 CID.
Max Marine RPM is 744 RPM. Railroad is 600-1200HP depending on the fuel rack setting, 800RPM max. Fuel consumption is 80 gallons of #2 Diesel per hour. Railroad is 16GPH at idle and 38 GPH at full throttle. Lube oil capacity is 160 gallons with 30 gallons being the oil filter. The EMD diesel is basically a BIG Detroit diesel. The difference is the route of air induction and exhaust.
The Detroit has the Roots Blower on top of the engine and the exhaust vented into an internal chamber called the "air box". The EMD Roots blowers are on the front of the engine and vents into the air box & through the "scavening port" then through 2 exhaust valves at the top of the engine. These are not "superchargers" even though they are known as such in marine applications. They provide very little "Boost" if any. 2 Cycle Diesel will not work without scavenging blowers. No lube oil is mixed with the fuel like an outboard motor, but gets its oil from an oil pan and two stage oil pump, one for lube and the other to work the governor & throttle The engines are connected to a reduction gear box where as on a locomotive are connected to a generator.

Yes. The Detroit Blows the exhaust into the "air box" on the side of the engine. The exhaust manifold(s) are located either above or below the air box. This is so the exhaust can be vented to the rear where as the EMD exhaust is vented so it discharges out the roof. Interestingly it because of this that you can't "Jake Brake" a Detroit. Only an "exhaust brake"

You should try and repost this video and lower the volume of the music because it over rides your voice information. Thanks to you, I'll be visiting the ship in two weeks.

@WB8BCO  Thanks I'm glad I had a hand in your up & coming visitation. Some of the music comes from loud speakers playing Big Band 1940's music which I can't do anything about, The other music is my error in not editing the sound track from a Big Band I play in. I use MS Movie maker & once you "Finalize" the movie, that's it. So there's nothing I can do except delete and redo which would take me another 1.5 hours. I'll watch this on future videos so this won't happen again.

@strobx1 Pg 4..cont'd. I also studied engine design..with a focus on 2cycle diesels (in the 60's) for 4 years, 3 of which were under Patrick N. who at that time was just retired as VP of R&D @ DD..who was there from the beginning & their very first engine..the 6-71. One last point, the exhaust manifold on DD's is located like any other engine..directly attached to the cyl. head at the exhaust port opening. The "air box" is at mid-block between two water passages, as is,EMD. Great Vid

@strobx1 Pg 3..cont'd. Exhaust brakes were Rarely..if ever, used on a Detroit..for two reasons, 1) their not very "effective"..Especially on a 2 cycle.& 2) because of excessive heat build up in the head(s) and the heads would crack all too frequently as it was, between the exhaust valves, without adding more heat via an "exhaust brake". I personally have Never seen an exhaust brake used on a Detroit (2 cycle)..only Jakes.

I have owned 3 trucks with 12V71's and "built" (hot rodded) many.

@strobx1 Pg 2..cont'd. You mentioned that the blower (multiple on V12's & larger) sit in between the banks / heads on the DD's..which is true, but on the inline engines, they of course are mounted on the side..also, the blowers DO produce "boost" (albiet due to "back pressure" NOT compression of air like a turbo or Lysham screw blower)..

to about 4 - 8psi above atmospheric, otherwise, no scavenging & cylinder filling could take place. JAKE brakes Are / Were used Extensively on DD's.

@strobx1 GREAT video for us "gear heads"...however, I'm going to take "exception" with you on a couple of details, namely DD's-vs- EMD intake & exhaust routing. The DD's & EMD's both utilize the "Air Box" for the SAME reason, & the exhaust route of a Detroit is straight out the ports from the valves in the head. Also the EMD's "share" a common "big end" of the con rod at the crank, as they utilize a 22 deg. firing order -vs- DD's 60 deg. The Air Box shares the same location in both.

great to see at least some of the landing vessels are still around in recognition of the guys who served in landing opps including my old man his boat was a bit smaller though (LCA's)  she a beauty strobx thanks for the posting

[kennjohnsen]

What is it you are saying, a Detroit blows the exhaust out the side of the engine ?

[roydora]

good vid thanks a lot.

[clank4001]

nice, the EMD 12-567A is historic in its own right

Great Video, Thanks for sharing
