It is a twin screw ship and they will beat you and the ship ( or plane) if they are out of synch. I have to do it by ear on the old plane.

Yep, we had Woodwards on the CAT D399's, not sure how that all worked in cooperation with the CAT pumps. No automatic phasing though.

I just had a 6-71 run away a few weeks ago. I've seen videos but figured it would never happen to me. Our old grader hadn't been started in probably 10 years. Fired right up. when I revved it it took off. WOW! Luckily the fuel line was just a rubber hose. I cut and it died. I never knew what one sticky injector could do.

Sounds like something used on a diesel genset. Maybe electric drive main propulsion?

Agree back when company had a few gen sets I know that many of them if not all had Woodward's. And they were fast to react to changes of loads, would make a D399 snap to attention fast.

And even if that D399 was only running at 1,200 RPM when the Woodward snapped to full fuel for a spilt second those 16 cylinder made it sound like a lot more. Especially if you were standing next to it in that van trailer that was barely big enough to fit the radiator.


Remember one time while test running one of them I was leaning over checking for signs of any oil leaks at the front of the engine. I was well back from the fan which also had the full guards in place, but the wind off that big fan managed to suck my hard hat off and blow it out the back of the trailer. Just at that time the boss happened to be driving by! As I came out of the trailer to retrieve the hard hat he stopped and said he was afraid to get out of his truck to check on me!

I got a tour of a Brinkerhoff Signal drilling platform while they were operating some years ago. They had three engine houses all three powered by D399's, two were on line while I was there. When those engine came under demand it was pretty fast and real loud. Those were Woodward controlled.

We had Woodwards on the two Fairbanks engines. They were isochronous in that they would hold the engine to 900 RPM under nearly any sudden load change. The frequency meter on the switch gear would barely move when the load went from 150 KW to 800 KW in an instant.

It was really heavy when there was a sudden lose of power and one of those engine automatically lit off at full throttle. These engines were a bit different than the run of the mill plant in that they had two fuel injectors per cylinder instead of the singles in a standard engine.

We were pulling into a harbor in Bermuda and had a tug along side when something happened in the aft engine room and the steam plant went down. The exhaust outlet went out the side of the hull just below the main deck level on the starboard side where that tug was tied off to us. I was standing on the main deck when the engine caught on and the tug boat disappeared in a black fog. The tug crew in the pilot house bailed out coughing, spitting black soot and swearing up a storm. They asked us for some soap that they could use to clean the glass on the pilot house after they tied the tug off to another place farther aft.

An unusual marine engine I recall seeing, Napier Deltic ( spelling?). Cylinder arrangement was somewhat different, alot of HP and cylinders for the size ( about 3000?)
British built? In '75 saw this engine sitting on the dock next to the type of boat it was used in. Some type of patrol boat the Navy had . Didn't hear it run. Think the story I recall was these boats had 2 of them and were fast. Boat resembled the old PTs, but 60's/'70s modern.

18 cylinders, 3 crankshafts, and the famous "Deltic Drone".....
There are two of those engines in that loco BTW.

Interesting. Thanks
Must have been a lot of work to keep running?
Not to take anything away from the Deltic,
But, Think I would prefer the 18 cyl Alco sound!

G..G..G..Granville.........!! Fetch your cloth.
Within the confines of the loco bodywork I imagine it was. A fleet of 22 Deltics took over from steam in the mid-1960s on the east coast main line from London to Edinburgh. Six out of the twenty-two have survived the cutter's torch and are in preservation.

They were the first locomotives in the UK that were officially authorized to run at a constant 100mph. Originally a number of them were named after famous racehorses, the association being with speed I suppose. Later most of the rest were named after famous British Army Regiments.
