A diesel generator is essentially the combination of an electric generator with a diesel engine to generate electrical power. This is quite a special case of generator-engine. A diesel compression ignition engine is generally designed to operate best on diesel fuel, but some models are also adapted to operate on natural gas or other liquid fuels. The main advantages of using a diesel as a power source are relatively low maintenance costs (as compared to gasoline) and the price of the fuel as well. Some diesel generators even come equipped with closed loop systems that allow them to function more efficiently at the beginning of a cold weather when they might otherwise slow down considerably.

There are four basic classifications of generators: those that use a two phase, high frequency drive (that is, drive forces that have a high torque rating); kva generators; single phase; and diesel generators that have a variable transmission. In addition to the type of drive, there are also differences in the construction of the internal combustion engines (IDEs) and the manner in which they supply power to the motor. Many diesel generators are small enough to mount inside a house or an office building while others can be as large as a garage or a warehouse. All of the various classifications of these generators use a common basic design though.
The two phase, high frequency drive kva diesel generators are the most popular with contractors and others who need temporary power. The problem with this type of generator is that its capacity is limited - it can only provide power for a limited amount of time. If you plan to use a single phase kva diesel generator outside your home, it is probably best to buy one that is slightly larger so that it can potentially provide power over a longer period of time.
A diesel generator that is powered by a single phase unit that has a high power output will cost much more than a small kva diesel generator would. For instance, a 2021 kva power output unit will cost a few thousand dollars in order to purchase and then install. A single phase unit that is capable of powering small offices will cost less than a thousand dollars. It is important to think about the power output capabilities of both units when you are comparing between different diesel generators.
In addition to the power output, you should also consider how well the engine operates and the noise level. Smaller diesel generators tend to have less noise than larger ones. Some diesel generators can operate quietly, while others can be quite loud. If you will be using small offices, you should factor in the noise factor. You should also consider the engine size because smaller engines tend to be cheaper. However, if you expect to use large offices that draw a lot of power, it is better to pay a bit more for a bigger engine so that you get longer lasting service.
Another consideration to think about is diesel fuel efficiency. Diesel fuel efficiency is important because businesses often run on a lower than average amount of fuel in order to save on costs. The higher the fuel efficiency, the less amount of money you will spend on fueling your machines. Diesel generators are also more efficient than gasoline generators. This fact can make a great difference in the amount of money you need to spend on fuel every year. There are many websites on the internet that will provide you with fuel efficiency information based on the engine type of your machine.
