Diesel Fuel Injectors.
When a gas is compressed, its temperature rises and a diesel engine uses this property to ignite fuel. Air is drawn into the cylinder of a diesel engine and is compressed by the moving piston at a compression ratio as high as 25:1, much higher than needed for a spark-ignition engine. At the end of the piston stroke, diesel fuel is injected into the combustion chamber at high pressure through an atomizing nozzle. The fuel ignites directly from contact with the air, the temperature of which reaches 700–900 C (1300–1650 F). The combustion causes the gas in the chamber to heat up rapidly, which increases its pressure, which in turn forces the piston outward. The connecting rod transmits this motion to the crankshaft, which delivers rotary power at its output end.
The generator’s fuel pump is a plunger type. They are moved by a lobe on the cam shaft that pushes on the fuel pump plunger to generate a precisely metered high-pressure pulse of fuel to the injectors.
Excess fuel at the injector is returned to the fuel thank by a “spill return” fuel line.
Generator Batteries
Batteries are often required to be float charged for long periods of time and must be able to deliver high current when called upon.
Generator batteries are sometimes sealed and maintenance free.
Lead Acid batteries are often used however because the content is an acid it is considered a hazardous material and often can not be shipped.
If your generator comes with a dry battery then you may be required to get it filled at Napa Auto Parts for example. The charge is minimal.
Most generators sold here come with sealed maintenance free batteries and do not need to be filled.
How the battery works.
A lead-acid battery is composed of a series of plates immerse in a solution of sulfuric acid. Each plate consists of a grid upon which is attached the active material (lead dioxide on the negative plates, pure lead on the positive plates.) All of the negative plates are connected together, as are all of the positive plates.
Generator Fundamentals
MAGNETISM
Magnetism can be used to produce electricity and electricity can be used to produce magnetism. Much about magnetism cannot be explained by our present knowledge. However, there are certain patterns of behavior that are known. Application of these behavior patterns has led to the development of generators, motors and numerous other devices that utilize magnetism to produce and use electrical energy. The space surrounding a magnet is permeated by magnetic lines of force called "flux". These lines of force are concentrated at the magnet's north and south poles. They are directed away from the magnet at its north pole, travel in a loop and re- enter the magnet at its south pole. The lines of force form definite patterns which vary in intensity depending on the strength of the magnet. The lines of force never cross one another. The area surrounding a magnet in which its lines of force are effective is called a "magnetic field". Like poles of a magnet repel each other, while unlike poles attract each other.
