Diesel Generators Explained
A diesel generator is composed of a diesel engine and an alternator or an electrical
generator, which converts the power created by the engine (expressed in RPM, revolutions
per minute) into the required voltage for homes, industry and remote work sites. The need
for power for homes and sites, which are not connected, to a power grid is a growing need
throughout the world. Remote areas of Central and South America are no longer too poor to
afford electrical power but not at the stage to built vast hydroelectric projects or large
power grids.
They can afford to build local village electrical power plants, which can meet the modern
needs of the people until the modern power grid can reach out to them. There are places in
the United States that are developing ahead of the ability of the local power company to
expand; other places throughout the world are at the edge of civilization. All of these
require power for business, commerce, medical treatment facilities and communication. The
price of the modern diesel generator, the new technology incorporated into these units and
their availability throughout the world make them an immediate solution.
Homes and ranches, villages and towns and remote sites should create a power needs list
that includes every appliance in the home, business, school and public facility in order to
determine the wattage needed. After this the home or ranch owner, city engineer or site
foreman can select the proper sized diesel generator. Every diesel generator is rated at
how many kilowatts of power it produces. If the home or ranch requires 22 kW to 25 kW then
the sized generator should be at least a 30kW. A brigade sized army unit twenty years ago
used a diesel generator(s) rated at 90 kW but its' needs were lighting and mess hall
refrigeration. Today it could be quite a bit more considering the new technology.
When you decide to provide power through diesel generators then you should consider whether
you need a backup. The power of the generator is rated at 50% engine speed. The 30 kW
diesel generator actually operates safely at 25 kW at 1800 rpm for prolonged periods of
time. It would be safer if the home or ranch had two generators scheduled to operate in an
alternating schedule of 12 hours each. This would ensure that the proper maintenance and
care could be given the generators while providing continuous power. Other considerations
in selecting a power generator involve selecting one that is a four-cycle, water-cooled
industrial diesel generator.
A water-cooled generator operates more quietly than an air-cooled and it lasts longer.
There are two electrical systems involved with a diesel generator, the DC (direct current)
and the AC (alternating current) systems. The recommended DC system should have a starter
motor with a battery-charging alternator with a solid-state voltage regulator. It should
have an engine pre-heat electric switch and start/stop switch.
It should have an emergency engine shutdown system to protect the engine in case of oil
pressure loss, excessive generator speed, over cranking and engine high water temperature.
Finally, it should have DC electric system breakers. Make sure that the AC system is a
four-pole revolving field and is has an AVR (automatic voltage regulator). These generators
will provide power that is within -+2% as compared to utility company variation, which is
-+5%.

Introduction to the Diesel Generator
There are several types of fuels that can be used for generators. It is however seen that the diesel generator is normally the choice of the commercial generator user. This is due to their ability to be both very portable and powerful making them suitable for a wide range of uses. In addition to these features there is also the added benefit of being dependable.
The typical electric generators is run at 1800RPM and is water cooled. This makes them great work horses as they are able to run for longer periods of time when compared to the gasoline generator and without much maintenance work required. They are also cheaper to operate due to the low fuels costs as compared to the other types of fuels such as gasoline and propane as well as the lowered maintenance costs due to there being no spark plugs and carburetors.
The diesel generator operation is similar to that of the diesel engine. There are two types of diesel engines. The 2-stroke and the 4-stroke operation are the two types. The 4-stroke operation is the one that is typically used in diesel generators. This process as the name implies uses four strokes.
The first stroke is the power stroke where a fine mist of diesel is sprayed on top of the piston in the hot compressed air space. The fuel is then ignited and the air on top of the piston expands. This pressure then causes the piston to move down and this motion is converted to a rotary motion by a rod that drives the crankshaft.
The next stroke is the exhaust stroke which is initiated by the momentum of the crankshaft turning and the piston then moves up. The next stroke is the suction stroke and this is when the piston reaches the top and the momentum continues so that the piston reverses in direction. The piston then moves down and the compression stroke is next where the direction of the piston is again changed after the lowest point. This cycle continues for the operation of the diesel generator.
Although the power generators is by far the cheaper generator overall it can cost a lot more to set up initially and this can be a deterrent to many generator users. The generators are also not as clean burning as the other fuel generators although this has improved much in recent times. The diesel generators may also require a larger store of fuel but this is much safer to store than gasoline. Another disadvantage of the diesel generator is that it can be a lot more noisy compared to their counterparts.
Many persons however believe that the savings that can be derived from an investment in the diesel generator are indeed well worth the disadvantages. The savings in fuel and maintenance are immense and the hassle free maintenance is a great plus. This is the reason many commercial generator users opt for the diesel generator. Diesel generators are available in mainly larger designs but can also be found on occasion in smaller units.
