I’m a former Navy engineman and career merchant marine chief engineer and master. Looking at the video brings back great memories and yes these are cool engines. On a nuclear ship we used them for emergency power and backup cooling for the reactors. 250 psi start air goes directly into the combustion chambers between the pistons via a pilot valve controlled by a distributor driven by the lower crankshaft. We had an air start reducer valve in order to maintain 250 psi. Our flask type start air receivers were maintained at a few thousand psi. These engines are around 3000 HP when turbocharged at 900 rpm. Very cool indeed.

the problem with these engines is the block was only designed for 750hp per cylinder @725 rpm the feild salesmen made comments that by increasing the rpm to about 900rpm a speedd the unit was never tested at you could get 1000hp per cylinder. then engine failure reports started coming in. fairbanks R&D test room set up a test engine and found that the oil pump was too small to handle the volume needed to run at 900 rpm. so they installed a higher volume pump. then the engines had gear failures that drove the oil pump. my fatherin law was the sr gear hobber than made all the gears for those engines. upper management blamed the hobbing department for the failures they sent 4 bacthes of gears to baber colman for inspection. the report that was issued was the gears were perfect.. dad told then the larger pump took more hp to turn than the old one they told dad he was not a trained engineer and to mind his own business. the R&D sepaartmen head said there was no way to measure the hp the larger pump would draw. dad said just drive it with an electric motor and measure the amps required and compare the 2 pumps , he was told he was crazy and to keep quiet. after a couple more weeks of haggling it was decided to discontinue the engine

***** thie engine in question was like the ones in the rRochelleillinois power plant one block from 1st ave between the two sets of railroad tracks they are 3 stories high from the centerline of the crankshaft and produce 1000hp per cylinder. the early model engines were designed to run 250rpm the next series 450 rpm according to the rpm graph found in the remains of the test building the one that blow up from a runaway about 2000rpm.in 1990 i toured the fairbanks factory and there is no link as this event predates VCRs and PC computers.. too many people now believe if there is no link it did not happen. well i talked to the witnesses the engine that exploded was a protottype it was a first start and the injection calibration blocks were left in the rack when someone was cranking the engine over and did not turn the fuel off to the injection pumps. the pumps were supposed to be disconnected and discharging into a volume measuring system to make sure all pumps was delivering the same amount of fuel to each injector. there were 6 techs trying to shut it down on the floor and 2 more in the control room three stories up when it blew. when the flywheel broke loose it went several city blocks before coming to a halt. think of a hunk of iron several feet in diameter more than 6 inches thick

Some of the more adventurous "fleet boats" ran their FM diesels at about 160% rated power during combat emergencies, probably along the lines of "disconnect the governors and watch 'em like a hawk". That was enough to achieve 24 knots, where normal rated power would give 21 knots, and apparently made the difference in terms of keeping a steam-powered destroyer at bay until the sub reached deep enough water to hide in; until the DD manages to light off its extra boilers, which takes something like an hour if surprised, it can't make anywhere near its rated top speed. They also made use of the cloud of exhaust smoke produced when revving the engines up to disguise their position. This was a double-edged sword, as it could also reveal their *presence* if previously undetected. Famously, the Graf Spee fell victim to the latter effect (though not with F-M engines) in the opening stages of the Battle of the River Plate, alerting the British cruisers to its approach; the Graf Spee was otherwise harder to detect than most warships due to the cleaner exhaust of diesel versus steam engines.
