Diesel
Generators are built to last. They’re
built to produce their rated output for years
on end. Most gas-engine generators are built specifically
to be used for intermittent or emergency power.
Almost all gas-engine generators run at a self-destructing
speed of 3600 RPM. Most diesels run at half that
speed.
The fuel-efficiency alone is a good reason for
a diesel generator, plus off-road diesel fuel
is cheaper than gasoline. It’s also a lot safer
to store. It’s flammable, but not explosive like
gasoline. And although diesels sometimes produce
more visible exhaust, it is less toxic than the
emissions from a gasoline engine. A well-tuned
diesel, by the way, produces no visible exhaust
except briefly, under severe load-changes.
Diesel Generators sound scary to some people
who are unfamiliar with them, but they are actually
simpler in design and construction than gas engines.
If you can service a gas engine, you can service
a diesel. And it requires less service.
The only maintenance generally required is changing
the oil, and changing the fuel, air, and oil filters.
This much is the same as on a gas engine. What
you won’t have to deal with is tune-ups. No carburetor
adjustments, no distributor or magneto to burn
out, and no spark plugs to need periodic cleaning
and replacement.
