Duel-Fuel Carburettors for Portable Generators – What They Are and Do and Why Use Them



In today’s world, where saving energy and caring for the environment are crucial, dual-fuel carburettors for portable generators offer a smart and eco-friendly alternative to traditional petrol-powered generators. These special carburettors let generators run smoothly on both liquefied petroleum gas (LPG) and natural gas, providing many advantages over regular petrol generators. Let’s explore what a dual-fuel carburettor is, how it operates, and the benefits it brings to users looking for a cleaner, more cost-effective, and reliable power source.

Understanding Dual-Fuel Carburettors

A carburettor is a device in an engine that mixes air with a fine spray of liquid fuel, usually petrol, to create a highly combustible mixture. While regular carburettors in portable generators work only with petrol, dual-fuel carburettors are designed to let generators use multiple fuel sources, including petrol, LPG, and natural gas.

How Dual-Fuel Carburettors Work:

  1. Petrol Mode: In this mode, the generator runs just like it would with a standard carburettor, using petrol as the main fuel source. Users can easily switch between fuel sources as needed, making it versatile for different uses.
  2. LPG Mode: When running on LPG, the dual-fuel carburettor takes LPG from a separate tank, mixes it with the right amount of air, and uses it for combustion. LPG is a cleaner-burning fuel, stored in a liquid state, making it convenient for storage and transport.
  3. Natural Gas Mode: When set to run on natural gas, the carburettor adjusts the air-to-fuel mixture to use this cleaner-burning fuel source.

6 Advantages of Dual-Fuel Carburettors for Portable Generators

  1. Cost Savings:
    • Dual-fuel carburettors significantly cut down on fuel expenses. LPG and natural gas are generally cheaper than petrol, providing expected savings between 30% and 60%, depending on the generator’s load.
    • Dual-fuel generators can run for longer periods on a single tank of LPG or natural gas compared to petrol, ensuring a continuous power supply during extended outages.
  2. Environmental Benefits:
    • LPG and natural gas produce fewer emissions than petrol, reducing harmful pollutants and contributing to a cleaner environment.
    • Using cleaner-burning fuels helps meet environmental regulations and emission standards, ensuring your generator operates within legal limits.
  3. Reduced Maintenance Costs:
    • LPG and natural gas result in a cleaner engine, reducing the need for frequent maintenance and extending the generator’s lifespan.
    • Dual-fuel carburettors are less prone to clogging over time, minimising maintenance and repair costs compared to regular carburettors in petrol generators.
  4. Fuel Supply Versatility:
    • Being able to switch between different fuel sources during emergencies ensures power continuity when petrol is scarce or unavailable.
    • LPG and natural gas, stored in sealed tanks, are less prone to spillage, evaporation, or contamination, enhancing safety during storage compared to petrol.
  5. Quiet Operation:
    • Generators running on LPG or natural gas operate more quietly than petrol-powered generators, making them suitable for residential areas where noise pollution is a concern.
  6. Fuel Availability:
    • LPG and natural gas are widely accessible and can be delivered directly to your location, making dual-fuel generators a convenient choice.


Adopting dual-fuel carburettors for portable generators is a significant step toward cost-effective, eco-friendly, and versatile power solutions. By enabling generators to run on both petrol and cleaner-burning fuels like LPG and natural gas, users can enjoy substantial cost savings, reduced emissions, and increased reliability, contributing to a greener and more sustainable future.

Dual-fuel generators are an appealing choice for homeowners, businesses, and communities looking to meet their power needs while minimising their environmental impact. As technology advances, dual-fuel carburettors are likely to become even more accessible and efficient, making them an increasingly attractive option for powering homes and businesses.
