Diesel Generators

Archive for March, 2009

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 diesel generator 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 diesel generator 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.

The cheapest operating costs are for Gas fueled generators. In sizes up to 100 KW Gas generators can be up to 30% more expensive than Diesel fueled generators with the same output. If Gas is available and you are going to operate your generator for more then 2000 hours a year, this can be the most cost effective solution Gas is also much more environment friendly. Kerosene engines are not expensive to buy and have comparatively low running costs. They are limited in output generally not exceeding 5KVA.An additional advantage in using Kerosene fuel is that it is less volatile and thus much safer than Petrol. Petrol Engines are the cheapest to purchase and the most expensive to operate. If you need a Generator to operate for up to three hours a day, they are a good choice. In general, Petrol fueled generators are limited to maximum output of 20KVA and minimum speed of 3000 RPM. Diesel Generators are commonly available with outputs from 5 KVA up to 2500 KVA. They are significantly cheaper to operate and maintain compared to Petrol, but more expensive then Petrol engines. If you need a generator for more then 3 hours a day, or a minimum of 1500 hours annually, it is recommended that you to buy a Diesel Generator.

Diesel Generators are  machines that generate electricity. The two main components of the diesel generator are the engine which supplies power and the alternator that turns power into electricity.

Choosing the right diesel generator may look like a difficult task, but choosing the right one can give you the most efficient and most effective diesel generator for you. First is to identify the tools and appliances you want to operate with your diesel generator. Next is to determine the required power for each item. Then add the required watts of each item that will be running all at the same time. Last is choosing the generator that has rated watts that exceed or meet the total power required for the tools. Another important thing to keep in mind is the Motor Starting. Keep in mind that induction type motors, like those that run sump pumps, refrigerators and compressors , typically require 2 to 3 times their listed running watts to start.

A friend of mine works on building sites and quite often uses diesel to fill up the generators. This quite often spills onto his clothes. Can anyone tell me what will remove the smell

The link below will take you to a Safety Information Sheet concerning the use and handling of diesel.

Dry Cleaning is the safest bet.

Don't whatever else you do attempt to wash them in a washing machine with an iternal water heater or tumble dryer.
