Now building one of those would be a dream job.

It's baaaaack.

Maybe the mods should just put this as a sticky link at the top!



Gadgett, welcome to the TDR. We are not chastising you, but this link has been posted quite possibly more times than we have had a transmission war or oil debate thread

Well, it is the first time I have seen it. Thanx for the info. Think the 6 cyl version would fit in a 5500 Dodge????

 

[KIseminger]

I got the same treatment when I put this link up here as well. I never get tired of seeing it though.....

 

[GadgettR1]

Sorry about that ... a friend just sent it to me and it was the first time I had seen it. . didn't realize it had been around for a while.

i second this thought. now this engine is way cool and so is any other large diesel engine, but i think this is the 5th or 6th time. and i don't see any problems with people posting about this engine [most are newer members and haven't seen it on here before or searched for it] but if this was a sticky, it would always be at the top. it could save a tinny bit of bandwidth if it isn't re-posted every few months...

this enging turns at 102 rpm you might think how can something run so slow but that 102 rpm out of that monster engine is equale to our cummins runing at 2100rpm, figure this out based on how may feet the piston has travled in one minute now when you think of it like that, at 102 rpm for that big thing is moven

when i was in school, we had a single cylinder lister diesel engine [hand crank baby ] that made 7hp, but something like 700 ft lbs of torque, and turned like 800 rpm [probably less, i never tached it... ]

 

[RobertBolinger]

It's an inline design

Eat your heart out V-8's !

 

[Jeff H]

Wonder if Peirs will have upgrades for it soon.

 

[Dennis Garrett]

I guess it's still true, "there's no replacement for displacement" (Dodge/Cummins would be the exception)

Did you see the size of the starter motor on the left hand side of the second picture. Looks like it is some how connected to the big sprocket looking gear on the rear.



With a engine that size that only runs at 102 rpm, how loud would it be while running,or just sitting there idling, and what would be the exhaust temperature be????



How mane FASS systems will we need to put on it??

that's not the starter. most engines this size use air to start them. they pressurize the cylinders to get everything in motion.



and it's 2 cycle



you don't need lots of rpm to make noise. the locomotive engines i work on only turn ±1000rpm and under load, them suckers are loud [and all the GE loco's we have get a nasty harmonic resonence over by right bank #6-7-8 when self load testing them]

hi trucki that electric motor may be a creeper motor so they have a way to turn the engine to work on it or it could be part of the oil pump system with big engines or electric motors the oil pump is a unit by its self this is so they can bring the oil presure up before they start it so they can float the crankshaft on its bearings so it spins easy and dose not wipe the bearing.

the e g t should be like the same as other diesel engines there would just be more volume of heat, well in this case a lot more volume

take care

Way cool! Nice post.

I agree cartman, the rod mills I use to work on had A oil pump that would run the pressure up to ten thousand psi. . Then the shafts would be running on an oil "wedge " in the bearring. . with very little cotact with bearring surfaces. . I miss that sound of A 2800 HP electric motor starting up. .

Looks like a jacking motor. An auxilary oil pump could be anywhere low on the engine, that motor is in a perfect place for the jacking gear. This would be used to both turn lock the crankshaft/propeller shaft also. Very important on a ship when people can actually go into a crankcase. A wave giving the engine a 1/2 turn while you are inside may ruin your day. We have a similar size motor for the turbine at work. About 50 HP and turns the shaft 1. 25 RPM. Rotating element around 600 tons.

hi cmac when you get into engines or motors this big things are different your dealing with alot of weight like that crankshaft 300 tons siting on thoes bearings you try to spin that engine and you will destroy it. when you pump oil into the bearings that shaft will float on the oil, like you said creating that oil wedge its only a thousands of an inch but that is all it needs. our truck engines are the same way when the bearings get oil every moving or spining part will be floating on oil. i have been lucky to work on these enormous engines and electric motors and if you think that 2800 hp motor was cool you should see and hear some of the ones i have worked on like a 22500 hp motor :--) now thats cool take care and write back about some of the big engines or motors you have worked on.
