A diesel generator is essentially a combination of an electric motor with a diesel engine to produce electrical energy. This is actually a quite unique case of generator-motor. Typically a diesel combustion-ignition engine is typically designed to operate on diesel fuel alone, although some kinds are also designed for use on other liquid fuels as well. Either way, though, a diesel generator makes an excellent generator and a popular choice for many industrial applications.
There are two basic classifications of diesel generators: single phase and multiple phase. A single phase generator will provide you the most power for your dollar. They use one fuel source – gasoline – in order to create the greatest amount of electric power. This kind of generator is popular in small diesel generators used in RVs, boats and other similar applications where there isn’t a great need for a lot of power.
In contrast, multiple phase generators tend to use a second fuel source – diesel. These are useful for larger diesel generator applications that require a high level of power. The best internal combustion engine for these generators is the internal combustion engine that is found in most gas engines; however, there are some diesel generators that utilize an alternative configuration that can work very well, depending upon the circumstances.
The primary function of any internal combustion engine (ICE) is to convert the mechanical energy stored in an internal product (in this case, fuel) into mechanical energy available to the engine. The process happens rather quickly, which is why it is often called a mechanical energy pump. In a sense, it functions just like the way a fan uses the pressure from a larger object to move air through a larger part of the device. The diesel generator works on a similar principle, but instead of using air to move around an internal engine, it uses the mechanical energy that is already stored within the fuel – just like a fan does.
To make things easier on consumers, many manufacturers have created both an electric and a diesel generator that will be compatible with many different appliances. For example, while smaller generators are often made to power small items in and around the home, medium to large sized generators are often used to power larger items, such as RVs. The larger generator will typically have three to five phases and more horsepower. As long as the electrical power grid that it will be connected to is reliable and can supply power when needed, the generator should be able to handle the demands that it may incur. Consumers should take into consideration the amount of electrical power that the generator will be required to supply before purchasing it.
Some manufacturers have also designed diesel generator generators that are available in water-cooled versions. Although more expensive, these units do not sacrifice the amount of power output that many consumers are looking for. There are actually many advantages to having a water cooled system on the unit. Not only will it increase the life of the unit and reduce the need to replace the fuel on a more regular basis, but it will also increase the power output that is provided at any given time. Many manufacturers recommend that consumers install a water cooled system on their generator generators, especially if they live in areas that are subjected to harsh weather conditions.
Another option that consumers may want to consider is investing in a diesel generator set. These sets will come complete with all of the necessary components, such as the compressor, the condenser, as well as the evaporator and turbine. While they do not have all of the options that an individually owned unit will have, a diesel generator set is still a good investment because they usually function more efficiently than other models. A kw rating is usually not included in a diesel set, however; you will need to check the specifications for this feature.
Of course, it is always a good idea to have both types of systems available. Not only will the consumer be able to benefit from the added advantages of a diesel generator set, but they can also use the electrical generator when it is not running. Just be sure to keep one of each on hand so that you can have emergency power available. A diesel engine is more likely to give out less torque, which will limit its power when an automatic or remote control is not available.
