Put this in your bus!!
« on: May 15, 2013, 05:43:08 PM »
I was at a trade show in Houston last week and saw this.  5000HP @900 RPM.  We would need Clifford to figure out the gearing for this one!!! :o

hey that looks like an EMD. I used to work on those for the railroad, only ours were only 2300 hp at 900 rpm.

We live 1 mile from the bottom of the hill in Roseville,California and hear those at night and in the mornings. I wouldn't be able to sleep if they didn't work on them anymore. "Big Orange" they call them here. :o 8)

It is a 20V-710 EMD (now owned by Caterpillar) train, generating, boat engine. If you looked at a cross section drawing of this engine, it is a big version of the 149 series (individual pot heads) and a direct cousin of our 53, 71, 92 series. Ironic that the railroad, tugs, generating plants are still using 2 stroke Diesels. And the largest Diesels in the world are 2 stroke engines-since you just simply cannot make a 4 stroke bigger then about 60,000hp (the 2 stroke 14 cylinder are around 130,000hp @ 102rpm) because of too much reciprocating mass. The big 2 stroke engines don't have counter balancing on the crankshaft since they only go up to 102rpm. But at a 98" stroke, that's like our 71/92 series running at just about 2000rpm. So it sounds slow, but imagine that 1500lb piston, 2600lb connecting rod going up and down 98" 102 times a minute. Next time you're on a excercycle, switch it to rpm and peddle up to 102 rpm-you'll see what I'm talking about. Good Luck, TomC
