Re: Effects of Running Diesel at Low RPM
Krush, in your scenerio, those guys should and probably would run WOT, and hope that over propping their engines did not tear them apart and start throwing rods through the blocks and even the thick Hatteras fiberglass hull which would lead to the same fate.

Re: Effects of Running Diesel at Low RPM
[QUOTE=Avenger;318719]Definition of insanity, is that why you keep repeating the quote?
See, here we go again, a simple quote from our friend Albert Einstein, and you get it wrong.
Albert mentions two conditions required to establish insanity. First that you do something over and over, second that you expect different results.
Since I absolutely DO NOT expect different results, the test fails. Very simple, two conditions required, one not met, test fails.

I think you misread my meaning there.
But funny thing is, I kept expecting different results too.--- The poster formerly known as Scrod ---

Avenger,
Your answer to my question re: fuel injection timing was very helpful...thank you!
You are the man.

Re: Effects of Running Diesel at Low RPM
BobK, there are people who are heavy smokers that live to be 100. Not sure that makes it a recommended lifestyle?

Re: Effects of Running Diesel at Low RPM
Oh Now I see
From Krush Link
Most Diesel generators run at 1800 rpm or even 3600 RPM. Not these!!! They run at a slow slow 1200 rpm. This is a design that is hard to beat.They come with a delco brushless alternator that also turns at a slow 1200 RPM. There are not many Diesel generators that are built this tough.Last edited by 34Hatt; 09-08-2017 at 09:21 AM.

Re: Effects of Running Diesel at Low RPM
The biggest problem with that is cost. Obviously a more complex generator with more copper will cost more. The other problem is engine power. The power curves for engines like that are pretty low at 1200 RPM so you need a fairly large engine for the power you're getting. OTOH large engines run at lower RPM so more poles in the back end are required to get the frequency needed.
For example these Nordbergs don't spool very high. The reciprocating components tend to be a little too massive to crank up to 1800, so a more complex generator is required.
