20V consists of 3 blocks and cranks bolted in a 6v.8v.6v patern. 2 cycle diesel @ 3.72 Liters per cylinder. Engine tested at 3000 Hp at 1900 RPM. Aug. 2004 I do not think DD built this engine. Does not look like a factory crew to me. The picture was taken in 2004. I once saw a pair of 24 cylinder's in Roger Penske's yacht. An awesome sight. Richard | ||

Morning Joe, Just what I need! A spare to go with my takeout. The buzzin dozen comes out this summer so I can put in an auto, I've already got a mechanical 8V92 waiting. What GM, Penske, or whoever doesn't advertise is their locomotive engine. They call it an EMD, (ElectroMotive Division) and it is just a 16V710TA. Depending on the locomotive, it produces either 4000 or 4300 horsepower, at 900 or 950 rpm. It was made with mechanical injection with a Woodward governor, now it is only "DDEC." Other than size, the only difference between it and a bus engine, is that it really doesn't have a blower, the turbo is gear driven by an over-running clutch which drops out at about 2/3 rpm, when the engine is putting out enough exhaust to run itself. They used to make them in 567, and 645 inches per cyl, and between 8 and 20 cylinders. | ||

... and the piston, rod, cylinder and head can be replaced as a bolt in unit. The cylinder has coolant lines from the main cooling system. Also there is no offset between the cylinders, the rods run on a common journal. One rod per journal has a rod cap and the other rod is just a ‘crow’s foot’ that is trapped in a slot of the capped rod. | ||

Penske does not own Detroit diesel any longer they are now owned by Mercedes. This is according to the people at reliabuilt in Byesville Ohio. We had a meeting there with owr antique truck club last year. I was also told during the meeting that reliabuilt would furnish parts for the two cycle engines for at least the next twenty five years. This is largley due to overseas demand. | ||

That said, The answer is that the 2-stroke diesels will be around the rest of our natural lives. Entire government weapons platforms run them. Tanks to Artillary. Boats run them, Oil Rigs run them, Ships run them. The best part is that Most are not electronic engines! No DDEC or any kind, all mechanical and basically EMP proof. The dumbest thing I have seen is an electronically controlled engine with an AIR starter. If the batteries are not Up you can't start it or it won't run. The mechanicals, Air start, No electronics, Spin it over and it runs and stays running. Only takes a pair of pliers and couple of bungee cords and you are on the road. I drove an air started RTS over 20 miles with no batteries, lights or electrical system of any kind. The harness had been chopped out before I got there. I unscrewed the bolts to the rack stop control, aired the main tank and twisted the air solenoid to trip the starter. Air throttle and air brakes and power steering.. That was I had to work with.... | ||

Now now, air starters have their own advantages and disadvantages which make them more desirable for certain applications than electric starters. If you drove a coach for 20 miles on public roads without an electrical system, that means you drove it without turn signals or brake lamps. That's not a smart thing to do. |
