World's largest diesel engine size of that ?      109,000 hp

Looks like the sort they use as a kick start for hydro electric installations. Awesome innit?

Got one of those in my Renault Scenic

What train is that gonna pull?

deliverance - 2012-11-19 10:43

i think its for a massive container ship that is currently being built .   correction it has been built .

got one bigger in my mk1 escort

Soo what motor are you using for the birdbath fountain?

claret.badger - 2012-11-19 12:56

doesn't look right - why's there only one turbo?

 

and an "inline" motor? poofs!

 

Most diesel powered loco's from the 1960's had at least 2

 

And the ones that had 4 were either bent 16's or deltics

 

and they were measily 2700-3300bhp

That`s gotta be for a ship. Did someone mention deltics? I still have, an instrument panel, that i removed from 55017, in 1982. Ah, i was foolish back then.

Its for the new SUPER PANAMAX container ships ( why 2nd Panama Canal is being made to accommodate 49 (160 ft) meter wide ships vs. current max of 32 meter

(105 ft) and 366 meters  long ( 1200 ft ) vs. 294 meters ( 964 ft).  Basically 50% larger ships.  The New Panamax canal expected completion date of 2014 at cost of over $5.3 Billion USD.  Super Panamax ships weigh 107,000 TONS !

   As to inline well since engine runs at max of 102 rpm this design probably allows least expensive mfg. of engine and balance is not much of a consideration at that super low rpm compared to car engine running 2000-2500 rpm at highway speeds and max rpm of 6500 rpm avg.

The size of the PISTON and ROD are about 26 ft or 8 meters in Length !!

That's amazing! What a monster!!!

 

what's the oil volume in the sump on this motor??

 

I must admit that the HP rating is impressive for a diesel, some  jet engines used on commercial aircraft create more HP  (115,000 hp used on the Boeing 777) why not try using some of the turbojet tech on shipping. Even through gear reduction they should be able to shrink the size of engine needed?

Probably DRY sump

deliverance - 2012-11-20 09:01

^^^^  yep for sure.

That's just amazing, here's another view of the engine. Check out the truck hauling it!

Who stole that from my shed.....it was used to fire up my latest boombox incarnation

Puny. Teeny-tiny little 2-stroke diesels
This engine is rather small compared to this:

 

 

http://www.gizmag.com/go/3263/
Wartzila Sulzer RTA96-C

 

Even the 12 cylinder one on the picture is not the largest, Wartzila also makes a 14 cylinder monster


These (ship or stationary) engines are all about EFFICENCY. Fuel efficiency to be precise. Up to 60% thermal energy of fuel turned into mechanical can be achieved with waste heat recovery (steam produced by exhaust gas heat drives electric generators through steam turbines. Electricity can run propeller shaft electric motors, induction fan/compressor)
Best diesel cars approach 40%, trucks approach 50% efficiency.

Turboshaft engines (or "jets") do not reach this efficency levels, especialy not with 300:1 reduction gear needed. Plus they are more expensive to maintain IMHO.

Only M.A.N. and Wartzila make these monsters - or more precisely: engines are manufactured by shipyards with license/plans/technology from those two companies, since they can not be transported for obvious reasons

They are two stroke, long stroke (2.5m stroke, 1m piston diameter), dry sump, turbo charged diesel engines, running on bunker oil.

 

With these engines I think the forced induction compressor is driven mechanically (or electrically) and not by exhaust gas turbine and therefore, technically, they can not be called turbo diesels but rather forced induction diesels

i used to love getting taken to school pulled by these things in the early 1980's

Made a hell of a noise with the right driver

It certainly wouldn't power your new computer Reno

Interesting info...

 

Amazing technology...The jet engine is actual very efficient for it's use, and has (suprisingly very few moving parts). For the airline industry 2 things are a must. Low fuel use and high dispatch reliability. Airlines will shy away from any engine with less that 95% dispatch garauntee. I worked for Air Canada one summer back in high school and learned a lot about a/c's

 

As far as heat recovery the jet engine does recover some of it's heat through bleed air which pressurizes and heats the interior of the cabin....Yes your cabin air comes from the engine (before combustion, but after compression).

 

I agree after reading the links you provided that these engines do seem to fall into the forced induction catagory. They made for a very good read.

 

I'm sure they carefully plan out their auto-route before building these things, I can imagine several brigdes that would break a sweat seeing these monsters rolling down the highway

 

Who says old dogs can't learn new tricks

True, jet engine is very efficient as aircraft propulsion source. Also energy density is very high  - about 8kW/kg, and way over 10 with afterburner (with much worse fuel efficiency and since Concorde is gone only reserved for military aircraft).

Also jets (turboshafts in this case) are great for co-generation (at chem. plants, etc.) - where they power electric generators and "waste" heat is used for plant processes.

The huge diesels have 300 times(!) smaller power density of just ~30W/kg!
The big ones at 2300 tonnes can not be moved, but are built in place. They are the size of a 5 story building, after all
