All You Need to Know About Diesel Generators
We have long left behind the time of gigantic Diesel Generators with loud rumblings. Now, a whole new generation of small Diesel Generator sets has entered the market.
They are not only quieter, but are also extremely efficient and powerful.
These new diesel generators have raised the bar on portable electric power generation. Here a few things you need to know, if you intend on using them.
Diesel Generators are different from petrol engines in their technical operation. In diesel engines, compression generation technology is used to ignite the fuel, while petrol generators operate on spark ignition technology.
In compression ignition, the air drawn inside the engine is heated with high compression, which also increases the temperature, and the fuel is ignited as a combined result of this pressure and temperature.
There is another aspect where a small Diesel Generator differs from a petrol engine. And that is the infusion of fuel and air in different stages of combustion.
In diesel generators, fuel is injected through an injector, while in petrol engines, air and gas, is first sent to the engine and then they are compressed together.
Similar to the petrol generators, there is a variety of diesel generators too. You can choose between an air-cooled and liquid-cooled version, or between two and four cycle generators, depending on the requirement and affordability.
Advantages of Diesel Generators:
Compared to petrol engines of same size and power, Diesel Generators are more efficient and offer better value for the money.
Here are some of the reasons that make diesel engines a practical choice for most users:
- Low fuel consumption – Although diesel is more expensive than petrol, it is packed with more energy per volume than petrol. Diesel generators need to burn only half the amount of fuel compared to petrol-powered ones to produce the same amount of energy. This low fuel consumption also means that the cost of producing per Kilowatt power is also a massive 35% to 50% lower in the diesel engines. Using diesel generators means more savings in the long run
- Quiet – New generation Small Diesel Generator sets are almost as quiet as their petrol-powered counterparts. They also require less maintenance
- Safe – As the fuel in diesel generators auto ignites and don’t spark, it is also much safer with less chance of an explosion
- Easy to maintain – Diesel generators are extremely easy to maintain. They also have a much longer useful life compared to petrol generators
Areas of Use:
Most of the modern Diesel Generators presently available for sale are designed for use even in the most demanding industrial and commercial setups.
Although, these engines are extensively used for small loads and domestic requirements, they are also suitable for larger loads such as mining and construction sites.
Similar to petrol engines, diesel engines have many different specifications regarding size and power. Choose a model that best meets your requirements.
