Hey,
We have a Onan Genset, that we picked up a few years ago for the house. Its a commercial genset, so its pretty big. I've been doing some thinking, What would the benefit of finding a hx-35 or smaller turbo, to put on it. If the RPM;s don't fluctuate at all, would their still be any benefit?

Thanks for input,

Mike

Edit: The Genset is a 45Kw...

 

Is it turbocharged now?

Bumping the power on a Genset really wouldn't do any good at all , besides possily increasing fuel comsumption.

 

no its not turboed now, we were wondering if there would be benifit to turboing it..

 

I think that is would be hard for the controls to work , it might fight the turbo lag & surge , the motor , running a gen. is ment to run maybe 2 speeds idle [ maybe not idle , how old ] and a constant load speed .

 

a few of our generators have a cummins 6bt in them, and they can hold a much better load than the ones that have the detroits. same generator too. if your generator bogs down and shuts off because of too much of a load on it, try putting on the turbo. but if your overloading the generator itself, thats no good, you just need a bigger gen.

 

What's the intended use? I'd like to see the residential estate that draws 45KW at any given moment....

 

Might want to check the compression on it, if it too high putting a turbo on it would be a bad idea.

 

No, no where near full load... Just wonderin what the benifits would be of just adding a turbo...

 

If it's not near full intended load, I would suggest just letting it loaf along and enjoy the fuel economy

 

Most gensets have much more engine power than they have current capacity. Adding power is pointless because you will dump the breaker before you will bog the engine down.

A properly sized turbo would increase efficiency and reduce fuel consumption.

 

Modern gensets are set to run at 1800 RPM this is to maintain the 60Hz frequency.
Generators run at a variety of diffrent speeds depending on how many poles are in the generator.

The 125 KW sets I work on go from 0 to 1800 RPM within seconds and transfers power, the oil and coolant are preheated. It has a turbocharged engine.

Several years ago a cat crawled up into the housing and made a nest next to the radiator to keep warm, when the exerciser automatically started the engine it never made it out. the fan blades broke and went through the radiator and out the housing, The set ran until the coolant temp got high and shut it down.
It was not fun job putting it back together.
Smaller cheaper generators usually run at 3600 RPM and may be equipped with an idle control that senses the load to speed up.
I have several ONAN CCK generators that run at 1800 RPM and are more desired.

 

Running a generator that is way oversized for it's load is not healthy for the generator and waste fuel.

 

What engine is running your genset, Mike?
