Emergency Generators - You can count on gasoline . . . to let you down!

Gasoline is not a fuel that professionals ever choose to use on emergency generators.  Hospitals and other large facilities "never" install gasoline powered emergency generators.  They always use natural gas or diesel.  Gasoline has a very limited shelf life and will actually cause engine failure.  Worst of all when power outages occur due to ice storms, hurricanes, tornadoes, earthquakes and all other disasters, the first commodity to be hoarded is gasoline.  Sadly, long lines (even fistfights) and rationing at gas pumps are a common occurrence during many disasters.   The hurricanes that hit Florida last year were sad proof of that.  However, working along with FEMA, we were called upon to be of assistance in helping in areas where gasoline was not even available to run emergency generators.  Propane, and especially natural gas, were more plentiful and just the ticket to keep the lights on and the crews working. 

Unfortunately, as some have learned the hard way, if not used often enough, gasoline will gum up the carburetor and will render an engine on the emergency generator useless.  Do not get caught with a gummed up carburetor that will not allow your engine to run, on your gasoline emergency generator that you cannot even get fuel for, when you need it the most.

If you have invested in an emergency generator, make sure that it runs when you need it the most.  Modify your emergency generator to run on propane or natural gas or even keep the gasoline option if you like and have the option to run all three fuels on the same engine!

Propane and natural gas can save you time, money and aggravation

Our do-it-yourself change over kits allow you to run your gasoline emergency generator on propane (LP Gas), natural gas, or all three.  Propane and natural gas are truly a backup fuel for a backup emergency generator.  Your engine will last longer, start better in cold weather and even start next year when you go to use it in an emergency.  The best part is, with one of our do-it-yourself kits you can change your engine from gasoline to propane or natural gas all by yourself.

 

Why use propane to power your emergency generator?

If you have propane available you know you can store propane for years because it does not gum up, go bad, or pollute the air like gasoline does.   You can use the 100# (24 gallon) cylinders, little bar-b-q grill type 20# cylinders, which is equivalent to 5 gallons of gasoline, or big tanks like 250, 500 and 1000 gallon ASME tanks.

 

Why use natural gas to power your emergency generator?

If you have Natural gas available you would certainly agree that it is probably the most dependable fuel on earth and virtually an unlimited supply.  Natural gas is always there.  It does not gum up or go stale like gasoline. 

 

Here are many more of the benefits:

·        Propane and natural gas powered engines provide the same power as gasoline.

·        Longer, uninterrupted run times!

·        Connect to big tanks or to your natural gas pipe line.

·        Your emergency generator will last longer because of larger fuel supply and less running out under load.

·        Clean burning Alternate fuel will help extend the life of your engine life

·        Eliminate the "Dirty Port" that gasoline carburetors have that shortens the life of an engine

Tri-Fuel Kits use an adapter that makes it possible to operate an engine on three different fuels; Propane, Natural Gas, and Gasoline.  Adapters will mix the Propane or Natural Gas into the air stream above the gasoline carburetor.  The gasoline carburetor remains basically untouched.  

This is basically how they operate:

The Adapter has a hose running to it from the demand type regulator supplied in the kit. The center of the adapter has a venturi.  A venturi has an opening in the middle and its shape resembles a doughnut. All around the trailing edge of the center opening are many small holes or slits. As air passes through the center opening and over the many small holes, fuel from the regulator is delivered to the air stream. How much fuel depends on how much air is passing over the holes which depends on how far the throttle is open.

People often ask about power loss with the adapter style kits. We have never had a complaint about power loss with any of our kits.  The use of a quality digital  tachometer should show this to be true.

A small readjustment of the main load screw will be required whenever the fuel is switched between Propane and Natural Gas.  To use gasoline just turn one off an the other on.  The engine runs on alternate fuel while the gasoline carburetor is "out of gas". 

So basically, adapter kits are not a conversion, they are an adaptation.

The regulator used in the Tri-Fuel Kit can accept gas pressures up to 14" water column.  Natural Gas is usually 6" to 8" and Propane is usually 11" to 14" on the low pressure side. (28" of Water Column is equal to 1PSI of pressure)
