A Buyer's Guide for Diesel Generators
Diesel and power are synonymous in today’s world. Eighteen wheelers, burly truck drives, and smoke may come to mind, but did you know this same power is used in common household and business generators?
Home or commercial diesel generators offer improved dependability and higher efficiencies in some applications. If you are interested in purchasing a diesel generator, use our guide to understand what makes this fuel so powerful, and how to ensure it works for you.
What Is Diesel?
Diesel is a liquid fuel. It ignites an engine in a 400 kw generator and other models by compression and heat rather than a spark. It is used in all types of heavy equipment.
Compared to gas, diesel is an oiler material, and it has a higher boiling rate. Also, by volume, diesel contains between 10% and 15% more energy. This translates into improved efficiency and power.
How Do Diesel Engines Work?
A diesel engine generator works by using the same four-stroke principles as the gas engine; however, it differs in the combustion process.
The process is as followers:
This is the first step of the four-stroke engine process. Air moves into the engine cylinder and pushes the piston down.
After the piston is pushed down, it will begin to move back up. As it moves, it compresses the air present.
When the piston gets back to the top of the cylinder, the fuel injector injects diesel into the air that has been compressed. This causes spontaneous combustion, in the absence of a spark plug. This reaction forces the piston to move back down.
The piston then moves back to the top of the cylinder. It pushes the exhaust gases out of the engine.
The reason that modern diesel generators don’t require the spark plug for igniting the air/fuel mixture is that the air is compressed more than with a gas engine. As the air is compressed tighter and tighter, it will continue heating up.
Now that you understand how a diesel generator works, it is smart to learn how to choose the right one.
Manufacturer Reputation and History
It is smart to choose a trusted and well-known manufacturer with a reputation for offering equipment that will be able to withstand the stress and the test of time. It is smart to look at online reviews and ask for recommendations when searching for the right manufacturer.
Some bad manufacturers sell the off-brand generators. Be sure you know for sure that the generator you purchase is a top-brand model.
Standby or Dedicated Generator?
Along with the manufacturer, you need to consider if you need a standby generator or a dedicated generator.
A dedicated generator is the best option when there aren’t any other power sources on-site or at sites that need a generator to use all day, every day. These are also called continuous or prime generators.
A standby generator will act as a backup source of power to a pre-existing power source. These are often used when regular power isn’t available, during a power shortage, or for other infrequent situations.
For an industrial unit, factory power requirements may be considered along with the available office power. Selecting a larger size is usually the best way to make sure your needs are covered, with enough power to last through an emergency.
KVA vs. KW
You need to understand the difference between KW and KVA. KVA and KW aren’t equal. Typically, the relationship between them will be 1KVA to 0.8KW.
When you are ready to purchase a diesel generator, you need to ask the salesperson about the generator unit and if it is given in KVA or KW.
You need to find out if the diesel generator muffler is of good quality. Quiet operation is essential for home use.
It is highly suggested that you purchase a low noise diesel generator or a silent unit. You also need to ask if the generator is fuel efficient before making a purchase. Because some generators will adjust the engine speed based on the load demand to achieve a higher level of fuel efficiency, this is important to know.
Both the fuel tank size and fuel efficiency are going to affect the unit’s run time.
Typically, the warranty for generator systems ranges from two up to five years. However, if you purchase an industrial diesel generator, it may have a one to two-year warranty along with a few optional upgrades.
It is smart to understand the warranty duration and the coverage offered for your standby system. Also, ask for upgrade costs if you want more coverage.
Generator Type, Age, and Hours
Do you need a single – or a three-phase generator? The age of the equipment and total hours it has been used should be considered, too. You also need to think about how the generator was used before you are buying it if you choose to buy used.
Other considerations include how well the equipment is maintained and if the load test indicates the equipment is still efficient when generating power.
