What is the difference between gasoline generator and diesel generator?

Generators can be used as backup power during a power outage and are an important part of maintaining job site productivity.

Do all generators run on natural gas? No, the two most common types of generators are gasoline and diesel. Each type has different advantages and disadvantages and is suitable for different environments and applications. Learn more about the pros and cons of both generators to determine which is best for your importing needs.

What is a gasoline generator?

BISON gasoline generators are usually connected to gas lines to generate electricity. In normal operation, a gasoline generator injects air and gasoline into a carburetor, which compresses both and creates an ignition that eventually spins the machine's rotors and generates electricity to power your equipment.

Advantages of gasoline generator

Gasoline generators, also known as gas generators, are the most common export generator types on the market and are very popular among owners. Gasoline generators are also known to be affordable because they run on gasoline, which is cheaper fuel, and BISON generator manufacturers offer more models and price ranges to choose from. At the same time, gasoline generators are also highly portable and lightweight, and users can move them as needed. They also operate very efficiently and are often used for short-term applications such as power outages. Gasoline generators are cheaper to purchase and maintain than diesel generators, and produce less harmful CO2 gas when running, making them ideal for individuals and small businesses.


Disadvantages of gasoline generator

Gasoline is a more volatile fuel than diesel, plus spark ignition makes using it riskier.

When gasoline burns, its combustion temperature is higher than that of diesel. Increased temperatures cause wear on the generator engine. As a result, components such as the carburetor may fail and must be replaced.

Unlike diesel generators, gasoline generators cannot run under high load for long periods of time.

Advantages and disadvantages of gasoline generator
Fuel is cheaper
The fuel is volatile and has some potential hazards
Portable and lightweightMachine parts are prone to wear and tear due to high temperature
Low purchase and maintain costRun time is shorter than diesel generator
Less harmful gas emissions

What is a diesel generator?

Diesel generators work by compressing air, then injecting diesel fuel into a chamber to generate heat, which triggers the fuel to ignite. The ignition powers the generator and produces electricity.

Advantages of diesel generators

BISON diesel generators are an ideal option if buyers want a generator that requires little maintenance. Known for their efficiency, diesel generators use compression to ignite the fuel, so they don't need to use as much fuel to run as gasoline generators. Diesel generators introduce and compress air and fuel separately into the engine, which allows them to use less fuel to generate electricity.

Typically, a diesel generator will operate at around 40% efficiency within its designed optimum operating range, often up to 80% of total load capacity. This means that for every 100 units of energy input, 40 units of energy are output. As with any mechanical system, energy is lost through heat and friction.

For diesel generators, efficiency can be expressed as specific fuel consumption in gallons per hour. Manufacturers often provide this information in their marketing materials.

And diesel generators are more durable, they can run longer at higher loads. Lifespan tends to be longer.


Disadvantages of diesel generators

higher upfront investment.

Older models make a lot of noise.

Diesel has higher CO2 emissions per liter of fuel than gasoline.

Diesel has traditionally been more expensive than petrol.

At present, the main diesel generator set models provided by BISON generator factory include:

Portable Diesel Generators —These are small units that can be easily transported by hand from one place to another. They're great if you want something lightweight yet powerful enough to power basic items like lights, TVs, and computers in your home or office in the event of a power outage or emergency.

Backup Diesel Generators —Backup generators are larger than portable models, but are still small enough to fit in most backyards without causing any damage to property or landscaping. They can provide enough power to power most homes and businesses during a power outage or emergency.

Advantages and disadvantages of diesel generator
More efficientHigh procurement and fuel cost
Use less fuelNoisier
More durable and last longerMore emissions

In recent years, many generator manufacturers have also continued to improve diesel and gas power generators, which means that the performance gap between the two has been greatly reduced. Today, diesel generators emit far less pollution than their predecessors, and many gasoline generators are being built with new technology to improve their economy-inverter generator. This allows them to compete with more efficient diesel engines. Both types are reliable.
