Quoted enough for you.

Just keep digging skippy.

Did you seriously just ask "What part is anti-Newton?" . Like you really can not possibly be that obtuse.

I guess you think that magic fairy dust is going to keep dumping energy into the flywheel to keep the RPMs..
Again all the flywheel will do is slow the change that is it. As soon as the inertia in the flywheel was consumed the rpms would drop. Its, not some perpetual motion machine much as you would like to think it is.

Now I see your problem. Reading comprehension. Work on it dude.

Oh so that is the excuse for you stating "You would not go up or down in rpms"
Getting desperate now are ya.
Nice try, but good to see you consistent with the back peddling.
So you just keep on with the excuses but it is very apparent that you do no have the first clue at all.

Words matter. Context matters. Try reading it again.

Ok Explain the context.
Explain how "With a flywheel of the proper design it would keep the rpms more constant regardless of the loading. You would not go up or down in rpms." has context. Go on now. Seems pretty straightforward to me as it also did to Dave.

You have had Multiple opportunities to explain that is not the intended "context" but not a peep till you get called on stupid.
Nice to see you digging that hole deeper with every post.

"With a flywheel of the proper design it would keep the rpms more constant regardless of the loading. You would not go up or down in rpms."


​​​​What I said above is that a flywheel would keep rpms MORE constant. Thereby stabilizing the rpms. Not constant, more constant. In context less change up or down in rpms due to the rotational inertia of the flywheel. I'm not saying adding a flywheel creates a perpetual motion. The chicken video was a joke. Off topic for fun. So anyone that was thinking it was real think again.

The 6.9 has a flywheel. It's designed for inertia with the thicker heavier rim. That's done to make the rpms MORE constant between power strokes of the engine. To smooth out the rpms and store energy as rotational inertia.

That's all I'm saying about flywheels. The things I thought 99 percent of our posters and readers already know.

Flywheels are used for many things. But in race cars sometimes flywheels are modified or changed to a lighter one for faster development of rpms. In the OP'S case he has a bare flywheel. Not connected to any drive train elements so it's a freewheeling flywheel. I suggested that he could try adding some weight to the flywheel. That would give him the same thing as adding a non transient load in the form of mechanical work. In his testing he discovered that above a particular load at a set rpm that control of the output was basically accomplished with the fuel injector pump at a fixed setting.

A heavier flywheel could be that mechanical load and would have the additional benefit of smoothing the output.

Maybe bolting on a ring or another whole flywheel would do it. Someone familiar with the design of flywheels would be needed to make those calcs. It's above my pay grade.

Nice try except "You would not go up or down in rpms" Sort of negates all the above. As does "I wonder if you can smooth it out by adding mass to the flywheel? That would add some resistance plus provide stored energy towards meeting increased loads"

Nice attempt at the back peddle though.

Furthermore, there is no RPM fluctuation to smooth out, but nice try, there is a consistent RPM, drop when a load is introduced, there is NOTHING to smooth out. A flywheel is not going to change that at all . This sort of like how you originally thought that there was no way that gen head would affect the RPM of the prime mover and were told differently. And insisted it would not change the RPM's. So how did that work out for ya?
Seems you have a hard time accepting facts based on proven formulas, and math. But the good attempt at back peddling trying to cover the idiocy of those statements.

Generator update

Today was a great test of the generator! I am extremely pleased with Ford Engineering. Between the thermostat and the fan clutch the engine alway stays at operating temperature. Today I hauled the genset to a remote area with my tractor and dropped it off to run power tools while I operated the tractor nearby. I slowed the drive ratio to 3.11:1 and operate the engine at 1175RPM. Somehow things are more stable (I suspect belt tension) and I set it up at 125V and it never dropped below 115V. I am still running on the original 10 gallons of diesel I put in to get the engine primed and running after hours and hours of running and testing. This setup is efficient, powerful, and possibly EMP proof!

I'm not surprised that your 6.9 could deliver power in an acceptable range at a set fuel delivery.

Any thoughts about enhancing your flywheel?

Flywheels maintain even torque. Look at those old tractors plow:


How big is your flywheel?

I only have the stock flexplate on it. I could bolt the torque converter back on if I wanted to add mass. (Even could fill it with concrete if I wanted further mass). So far things are great!

I need to add an hourmeter. Not sure of the fuel consumption, but someone on FTE estimated 3hr per gallon on the 6.9 and that may even be conservative.
