Same advantage as any 2 stroke vs 4 stroke. A 2 stroke completes all four phases of the combustion process in one complete revolution of the crank as opposed to two revolutions of the crank.Whst is the advantage of a 2 stroke diesel vs. a 4 stroke diesel?
Not really ,I've just been around the installation of a few large high voltage generators .The GM 16 V 278's and FM 10 D 81/8 were WW2 submarine engines which I don't operate but part of my qualifications were I had to know how to start them in an emergency .That's a long time ago and I'd have to do some thinking now of days .I'd fumble through it some how .I will say this 4 big marine diesels running at flank speed is like music to my ears,the sound of a V twin Harley at 4500 rpm or a two cylinder John Deere tractor under a heavy load .Sounds like you have some experience with them also.

I love the sound of a detroit. Sounds like it’s goung 100mph when it’s going 5mph. Lola lot of 671's lost their blowers. mostly at night. had to do with light, space and time
That's still used today but they have also added the ability to measure the peak cylinder pressure relative to crank degrees so you can check fuel timing and overall health of the cylinder.The 71 series GM were the Briggs and Stratton of large engines .From the 2-71 to the largest I've seen being the 12v 71 .If they needed more power they just hung another cylinder on it .Oddest I've seen was a low voltage generator between two 12v 71's ,one running clock wise the other counter clockwise .I think each engine was about 400 HP at the RPM they were running .That was a long time ago too .
A note on that ,might sound crude but the way those two big engines were sync tuned in was with an exhaust phyrometer ,measuring the exhaust heat .
That high tech stuff is way beyond my pay grade so to speak .I'm so old school all I know is the now ancient "Edwards board" method of syncing single engine prime movers .three lights .if memory serves one bright two dim, syncro scope at 5 til 12 .Throw the transfer switch and one of them would roar like a lion as it synced in and picked up the load .Black smoke just rolled .
Oh yeah, syncing we still use a good old sync scope. The engine analyzer is just to check the engine is running the way it should. Check for weak/strong cylinder(s). Otherwise, never heard of an Edward's board. Then again I'm not an operator either...That high tech stuff is way beyond my pay grade so to speak .I'm so old school all I know is the now ancient "Edwards board" method of syncing single engine prime movers .three lights .if memory serves one bright two dim, syncro scope at 5 til 12 .Throw the transfer switch and one of them would roar like a lion as it synced in and picked up the load .Black smoke just rolled .
