4 cylinder 28VDC Military Generator set question

Just what can I do with it. Its the typical military stand engine,
made by Teledyne or continental, but it has a lousy 28VDC generator on
it. Its fairly large approx 30 inches wide n 24 inches high and about
3 feet long. It runs like a champ...........but 28 VDC is not gonna do
me much good. It was obtained for free............so I sure was not
gonna turn it down........

Could you get an inverter that converts 24 volts to 220/110 VAC for houshold use as a "back up" generator?
For the past few years, I've spent some alot of time repairing high current 28 VDC generators for aircraft ground power units. If it is big enough to seat their needs, maybe you could give it to someone at the local airport, or even sell it if there is enough need there.

Use it to charge 24V batteries to feed a UPS inverter circuit? Gerry :-)} London, Canada

What is the RPM on that genset?

Find someone with a 24V nominal golf cart, and give it to them. Instant Hybrid Car. Or a field charger. Starting boost for industrial engines in graders and Cat D-9's. Or as an emergency source for someone living off-grid, and everything's on a 24V solar cell and battery system.
If there is a way to reset the voltage regulator for 13.8V DC, now you have a car battery charger or booster start unit. Perfect the next time you get in the car to go to work, turn the key, and get rurrr-rurrr-clickclickclick.... as it turns over once and quits.

You can make a voltage divider (Google), to drop the uneeded voltage. If you use a 50 ohm potentiometer and some resistors in parallel, you should be able to vary from 0 to 28 volts.
Use a voltmeter to measure the output voltage. You would want to use no more than 13.5 VDC to charge or run a 12VDC battery or system.

Build an experimental aircraft. Lot's of them being built and powered with those engines. OR find a large 24 volt motor and build a hybrid auto.

If that 4 cylinder engine is air colled and looks a lot like an aircraft engine then it is worth something as parts. Many of those engines had a special crank case but aircraft rated parts. Homebuilt arcraft can use the case, after modifications and regular aircraft can use the other parts if they have model numbers that indicate "aircraft worthy".
Check aircraft engine rebuilders.

Get a big-assed UPS and use it as an inverter - get the equivalent to a Honda E series inverter genset.

That would have to be a UPS that uses 28V batteries, quite unusual. Most big UPSes have many batteries connected in series, resulting in relatively high DC voltage.

It still sounds like a airplane engine driven generator. Many of them had a special crank case but aircraft rated other parts. If so, you could sell the aircraft parts and buy a generater.

These gensets sell for not too much money on ebay. I doubt that he'd be able to make a lot of $$ on it to afford something decent. I do like the suggestion of adding either a belt driven, or direct/flexible coupled head. That's the sanest use of this equipment, in my humble opinion. My own generator experience is limited to restoration of an onan diesel genset, and reselling a few generator parts.

Gonna scrap the generator and all its associated equipment, and utilize the engine for a bandsaw wood mill........
Solves that problem........

Many UPS systems run on 24 volts, and 28 volts is the charging voltage for a 24 volt system, give or take.

Roy, I think what you have is a Continental engine... a variant of an air cooled aircraft engine and a 28VDC generator, probably for use in starting aircraft.
If you are interested in a donation to a school, I can give you a tax write-off....

Motor is a continental. Unit was used on the command type APC's to power a heap of radio equipment etc.
