93,000 HP Hyundai???

[Antoine]

Somehow I started watching this TLC or Discovery channel thing on Hyundai Shipping....I can't explain why...but anyway did you know they make the worlds largest engine!

They make this engine to power the freighters...It's 4 stories tall and makes 93,000 HORSEPOWER...I nearly lost it when I saw the size of the crankshaft...I thought BB Chevy cranks were huge..try one the size of several buses...even big rigs!

To top it all off I don't recall seeing any methods of forced induction...umm Spoolin...got anything in mind? lol

Now if you could only swap that beast into say the new Tiburon.

 

[Gyre]

Aren't most of those large engines turbines anyway? There should not be much exhaust pressure to use and little to do with it.

Actually...

"Antwerpen Express has been fitted with a seven-cylinder MAN B&W two-stroke K98MC engine. The engine was developed by MAN B&W in Denmark and its twelve-cylinder 93,360bhp configuration has been chosen by Hapag-Lloyd for its 7,200 TEU series of containerships under construction at Hyundai.

The earlier series of Hannover Express class containerships were fitted with the K90MC engine, which was the widest two-stroke machinery at the time of ordering. The greater power density of the K98MC has enabled Antwerpen Express power needs to be met with two cylinders less than the nine cylinders used in these preceding vessels.

The 9K90MC installation in each of the Hannover Express sisters delivers 55,980bhp at 94rev/min, at a mean effective pressure of 18bar, whereas the seven-cylinder examples for the Antwerpen Express series turn out 54,460bhp at the crankshaft speed, on 18.2bar. The slight reduction in maximum power was regarded as acceptable on the basis of the speed performance of the vessels already in operation.

The 7K98MC engine is supercharged by three units of the TPL85-B11 turbo charger design developed by ABB Turbo Systems based in Switzerland, providing one of the first applications for the new TBL-B generation, tailor-made for two-stroke machinery."

That's nothing compared to the horsepower Hyundai "lost" over the last 10 years...

North America loses about 5,980,000 horsepower:
You say your Hyundai Elantra isn't pulling the quarter-mile times you expected? This is because it makes less power than Hyundai told you when you bought the car. In fact, according to a recent Hyundai statement, 1.3 million cars and trucks sold in North America over the past 10 years make less power than advertisedby an average of 4.6 horses per car. In the worst case, Hyundai overrated the horsepower of the 2.0-liter Sonata by 9.6 percent (claimed: 137; actual: 125). The company says it never had an established procedure to verify that horsepower matched its preliminary estimates. The overstatement also applies to Kia automobiles, such as the Optima, that use Hyundai running gear. The companies are offering an extended warranty or extended roadside assistance to owners of affected vehicles.

As some of you may know....i was in the navy.....the ship I was on had 280,000 shaft H.P. the ship was powered by steam turbines. 4 of them.....70,000 hp each.

 

[PA_MP3_Man]

Shoulda slapped a mazdaspeed sticker on the side of her sir nuke.

 

[Protege01MP3]

NAVYSPEED Protege...

 

[Sir Nuke]

Shoulda slapped a mazdaspeed sticker on the side of her sir nuke.

all I can say was that sucker "HAULED THE MAIL".....she displaced 90,000 tons....and we could go from 0 to 48 knots (56.6 MPH) in 4 minutes 20 seconds.....stoping was another matter altogether..lol took about 20 miles! lol

how much fuel do these huge turbine engines burn?????? i'd imagine gallons of fuel gushing into them being burnt ever millisecond..

So they do use F/I on engines of this size

So why do they make engines so large when they could use turbines? I have no idea about the proper ways of powering a ship...just curious.

I have seen helicopter engines (turbines) used to power those insane tractor pullers...not one but 2 used on one tractor...I think she was putting out around 12000 hp if I remember correctly...

What are the power characteristics of turbines...I guess in this case...gas turbines. Do they produce maximum/insane torque at low revs?

 

[pr5owner]

NAWWWWWWWWWs anyone?

Wil, notice in my FIRST post I said STEAM turbines.....steam power....steam created with the heat from NUCLEAR POWER. this baby runs for an average of 15 to 20 years WITHOUT refueling. :{D

however....the u.s. navy DOES have some fast friggets which have gas trubines for propulsion....but the carrier I was on would out run any one of those too :{D

economics mostly.....for to have a steam plant you STILL will have to burn some kind of fuel....typically the fuel burnt in ships boilers these days is actually VERY VERY high quality deseil fuel...also known as jet engine fuel. also it takes more personal to run and maintain a boiler and steam plant than an internanl combustion propulsion unit.....

As for the power characteristics of the gas turbines....the answer to your question is NO, they do NOT produce max torquea t low revs....typically the trubines are high rpm performers...then they drive a gear set the slow the shaft down to a speed that the props can operate at.

I used to develop computerized PM systems in Central America for power generation systems. They burned heavy fuel in each of the engines, sometimes up to 10 engines in a plant. One engine was easily twice the width, height and length of a big rig. They would produce between 3 and 20 MegaWatts of power each. Max RPM-900 (yes hundred) The pistons were about 4 feet in diameter and about 3 feet tall. When the engines blew, things got loud and messy.

we have six emergency back up generators here....they have cooper besemer KSV, V-20's, they run at 600 rpm.....they are the size of a train locomotive and each powers a 5.5 Megawatt generator......

heh, no need to start an old thread up, but the worlds largest motor was actually designed/built by a friend of the family. Jack deVries (former ABB contractor) built the worlds largest motor for NASA-LaRC (a 250,000hp Synchronous Motor) used in an air craft test bed (wind tunnel). Just a little info

 

[Notorious]

think it'll swap into my del sol?? with the same mount locations?

 

[ChuEy826]

My Mazda Protege 5 puts out 130 horsepower... and I bet I can beat that windtunnel in a quarter mile

For that reason, most marine gas turbines are used to drive a generator while the exhaust is used to generate steam and drive another generator. The power from the generators is used to drive motors for the propulsion system. This way, you're not limited to the hp/torque limitations of the actual gas turbines.

Almost all new cruise ships are powered this way because they can also use the power for things other than propulsion.
