What Is the Difference Between Gasoline Generator and Diesel Generator
What is the difference between diesel generator and gasoline generator? I think this is a question that most people want to ask when opting for a generator. No matter for prime power or standby power source, there are many routes to go with. Both of diesel generator and gasoline generator are good and each of them has their own benefits. To get a deep look at the application along with some personal preference analysis from cost and other features to available fuel source and emission regulations, examining key aspects will help determine whether your application is best suited for diesel VS gas generators.
If you're looking to keep the power on when the utility grid fails, you might find yourself clicking between a gasoline or diesel powered generator. Other fuel options are available, like natural gas or even solar powered, but for the average homeowner, gasoline or diesel will do the trick when you need back up power. So let's talk a little about the differences between gasoline and diesel.
Gasoline Generators
Engines operating on gasoline will mix the fuel and air together in your carburetor before compression. Though gasoline is typically a more easily attainable fuel source, it is less fuel-efficient than diesel. On the plus side, gasoline does increase the portability of your generator, which means you can take it from your home to the construction site, and out to your camping spot for a weekend getaway. A gasoline generator requires little maintenance and is typically more affordable than a diesel generator. At the same time, gasoline is flammable and offers a much shorter shelf life than other fuel types.
Gasoline generators are ideal for small jobs, and since these systems operate much more quietly than diesel-powered systems, you can use them in close-quarter environment without much distraction, like at your local farmer's market.
Pros of Gasoline Generators
Natural gas generators are usually connected to a gas line, creating an on hand, readily-available fuel source
The generators are great for prime power applications because of the consistent fuel source
They cost less to build and natural gas generators typically cost less for longer periods of time than diesel fuel
Natural gas is cleaner with less emissions than most other fossil fuels
The generators do not have the pungent odor associated with the burning of diesel fuel
Cons of Gasoline Generators
Natural gas generators require more maintenance, resulting in higher maintenance costs and more downtime
The generators have a shorter lifespan
They are larger and take up more space compared to the diesel counterparts
Natural disasters can disrupt natural gas flow
Natural gas is explosive; fire hazards can occur should a pipeline burst
Despite being a relatively clean fuel source, natural gas emits more carbon dioxide than diesel
Diesel Generators
Diesel generators provide operators with the least flammable fuel option, and in times of emergency or disaster, a more easily attainable fuel than that of gasoline. A diesel generator operates by igniting fuel through compression. The diesel fuel and air are introduced to the engine separately. Only the air is compressed, which means your engine will run more efficiently while using less fuel.
Years ago, diesel generators were known for being noisy, but with recent technological innovations, many diesel generators are now quiet enough to run in your own neighborhood without disturbance. Without a carburetor or spark plugs, your diesel generator will require less maintenance than its gasoline powered counterpart. For those needing extra power for heavy-duty tasks, invest in a diesel workhorse. Their engines are designed to work under a load for longer periods of time, and actually perform better when worked harder versus light-load operation.
Pros of Diesel Generators
Diesel generators require less maintenance, resulting in a lower maintenance cost
The generators are sturdy, reliable and have a long lifespan
They are typically smaller in size when comparing similar capabilities of gas generators
Diesel generators are ideal for mobile, portable or rental applications in addition to stand-by power sources
They are fuel efficient when compared to the same volume of gas needed in gas generators
The generators are safer; the fuel is less flammable and less explosive
Tier 4 generators emit less particulate matter and nitrogen oxides compared to previous models
Cons of Diesel Generators
Cost is affected by the fluctuations in diesel fuel prices
Diesel generators tend to cost more due to Tier 4 regulations
Diesel generators are louder than their gas counterparts
Diesel fuel is not readily available on hand, instead stores of fuel must be kept or procured to run the generator
Generator maintenance can’t be overlooked. Unscheduled downtime and longer-than-expected routine maintenance can greatly impact any business’s operations. Whether using a diesel or gas generator, having the know-how to run a generator efficiently will keep the power running optimally, yielding a longer service life.
