How Do Dual Fuel Generators Work and How to Choose One?

Dual fuel generators are one of the best ways to make sure that you can get a reliable source of electricity. Because of this, they are a popular fixture for both businesses and private residences. However, these devices can often appear to be complex. Let’s break down how they work and look at some of the things you need to consider when choosing one. 

What Is A Dual Fuel Generator?

A dual fuel generator designed to use two fuels at the same time. These can be mixed, or used alone, depending on the circumstances. For example, they might ignite using diesel, as it tends to combust easier. But, once running, propane will be added into the mix. As we’ll see later, there are many fuel options for you to consider. 

There are a few reasons why this type of generator is so widely used. First, it tends to be easy to start. This can be a big benefit if you need to use the generator urgently, like if you’ve been impacted by a natural disaster or have lost power to your business. Another benefit is that these generators can often be optimized to burn cleaner. This ensures that there will be fewer emissions produced, which will lower your environmental impact.  Also, these generators will be able to run for a long time. Finally, in most cases, they won’t require a lot of effort to maintain. 

How Does A Dual Fuel Generator Work? 

To understand how a dual fuel generator works, let’s take a closer look at each stage of the process. First, you’ll need to start the generator. In most cases, it will require one specific type of fuel to ignite the engine and warm up the machine. Without this fuel, the engine won’t start. Once it’s warmed up, the other fuel will slowly be added in, until the right mix between the two has been achieved. Most dual fuel generators will be able to run on one fuel source.  This can be helpful if the fuel supply gets disrupted, ensuring that you’ll be able to keep the lights on.

It should be noted that a dual fuel generator is different from a bi-fuel generator. This is often one of the most confusing parts of choosing a generator, especially if you don’t have a lot of experience in this area. As we mentioned, a dual fuel generator will use two fuels at the same time, mixing them to get the best results. A bi-fuel generator is also capable of using two fuels. However, they’ll only be able to use one at a time, depending on which one will be the most efficient.   

One of the reasons why a dual fuel generator is so popular is because of the flexibility that it will provide. In most cases, the generator will come with multiple settings. For example, you’ll be able to set it to come on automatically when the power supply is disrupted. In other cases, you will be able to choose how the fuels are mixed. This ensures that you’ll be able to make sure that the generator is set-up the way you want it to be.  Most devices will come with an owner’s manual, explaining in more depth how the device works. This will give you all the tools you need to start customizing the settings.

Types of Dual Fuel Generators

One of the reasons why people love the dual free generator is because there are several options for you to choose from. First, you’ll need to decide which type of fuel you want your generator to use. There are generally a few options for you to consider. First, as we mentioned, you’ll be able to use diesel. This tends to be fairly popular because it’s easy to obtain and relatively inexpensive. Another potential option is natural gas. Often, this is the cheapest form of fuel. You might be able to get a natural gas tank or choose to have it piped into the generator. A third option is propane, this can be stored for a long time and tends to be fairly cheap. Finally, you might want to choose gasoline. Like diesel, this is widely available, though it tends to have a shorter shelf life. 

Next, you’ll need to decide how big you want your dual fuel generator to be. They can come in all shapes and sizes. For example, you might be able to get a smaller, portable model which can be perfect for taking on a family holiday. However, there are several big options, which will deliver enough electricity to power an entire business. In the product specifications, you’ll be able to find the level of electricity that the device produces. Often, this will be measured in watts. You should be aware that the amount of power produced might vary, depending on the type of fuel mix you’ll be using. As a result, you might see a range of wattages. 

There are a few other options that you might want to think about. For example, some generators will need to be worked manually, while others can be operated using your mobile phone. You can also think about how much noise the device will make.
