Cummins new engine - Hedgehog

[WHazelwood]

Cummins







Horsepower and speed generally go hand-in-hand, so you’d expect a 4,000-horsepower engine to sit between the fenders of a particularly wild resto-mod show car. In the case of the 4,000-horsepower Cummins Hedgehog, however, we can name a single car large enough to accommodate the diesel engine’s bulk.



The Hedgehog, you see, wasn’t designed for cars or over-the-road trucks. Instead, the massive 95-liter engine was built to power mining dump trucks, the largest locomotives or generators with enough capacity to power 3,500 average houses.



Each of the engine’s 16 cylinders displaces over six liters, roughly the size of an average Cummins-powered delivery truck or city bus engine. In addition to making 4,000 horsepower, the Hedgehog engine also cranks out some 11,800 pound-feet of torque, yet still complies with upcoming European Tier 4 Final emission standards.

here is one... generator engine... also being installed in mining equipment and such. .



Hope this link works.

210 gallons of fuel per hour at 100% load... ... ... ... Wow, that is big riggin' there Wingate...

That one is smaller than the Cummins, but its about 4200 hp. !! They get MUCH bigger than that though. . Think that one is about 85L, we have them at 360L and larger!!!...

Appartently the Cummins is a new design??...

 

[mwilson]

On the way to work this morning I passed the time by calculating fuel consumption for that thing...



Most notable number I remember is 37 hours of run time at 100% load would require an 8,000 gallon tank trailer full of #2 fuel oil. Wow... .

Yes, last year Diesel Progress had a big article on the QSK95 (starting production) and QSK120 (20 cylinder variant to come).

Cummins invested in building a new plant to make the engines, which are the largest in-house engines in company history (they've made larger engines, but always with a partner in the past).

This represents a huge investment by Cummins, and judging from the latest power generation order survey I saw, a damn smart move. Reciprocating engines are selling like hotcakes while gas and steam turbines languish. Meanwhile Cummins doesn't make particularly large engines, and is being eclipsed in the large power generation market by companies like Waukesha (now owned by GE, I think), Man, Fairbanks Morse, and others. A lucrative market, considering the growth in worldwide power demands.

Here's a link to the original press release on the QSK95.

Interesting press release, but claiming to be the highest hp. 16 cylinder 1800 RPM diesel is a bold statement... guess press releases are like diesel pickup truck commercials...

Will be interesting to see an actual performance spec sheet on it... . I would love to compare it to some of Cats offerings...

Wonder if these engines have made it into production yet? Whos buying them, and how they are doing?

I have loosly kept up with the Cummins natural gas engines... . they have been trying to gain a foothold in the marketplace for several years now, but with almost no success... I think they are making strides, and the little 5. 9l NG engine will probably replace the old Dorman fleet... . but they are going to be hard pressed to replace the industry standards such as Cat and Waukesha... .

When working I use to do Regional Trauma Hospital fuel drops and sometimes to pump out old fuel and drop new in 30,000 GAL tank. It fed 4 Detroit Gen Sets about like above. Got to see a test one time cranked up all 4 Gen's to make sure everything was good THE NOISE WAS UNREAL !!!!!!

Typical power plant engine installation shown below. These are 400 RPM 16 cylinder Cooper-Bessemer LSVB-16-SGC CleanBurn units. Note the 2 men standing at the far end of the engine room.

Interesting pic... . since its a slow speed, looks like they are turning a gearbox to increase speed, but what is it they are driving?? looks like just a big output shaft with a beltguard around the end of it!!. . Surely its not driving belts down to a generator???

Oh, theres another guy standing on the catwalk of the second engine!!. . hahaha. .

Wonder how old that pic is? any ideas?

 

[RustyJC]

The "box" is a direct driven AC generator - no gearboxes. The shaft extends out to an outboard bearing to support the weight of the generator's rotor. The picture dates from the late 1980s or early 1990s when the units were commissioned - the engines are generating heat and power for the Orange County (CA) Sanitation District. The excess power is sold to the grid. The heat comes from waste heat boilers - if you look closely, the exhaust from each engine discharges from the turbocharger and goes into a waste heat boiler.

interesting... Im used to the big Kato generators... that "box" design looks like an old GE generator... Makes sense about the support bearing for the rotor now that you explain it. . Sure would make it much easier for performing alignments. .

 

[RustyJC]

Could well be GE - normally, our customers spec'd either GE or Ideal for generators behind the LSV-series engine.
