Quick Answer
Multi-fuel diesel generators can run on a variety of fuels including diesel, biodiesel, and kerosene, offering flexibility and adaptability to different environments and fuel sources.
Fuel Options and Compatibility
Most multi-fuel diesel generators can accept a range of fuels, including:
- Biodiesel (B20, B100) for a more sustainable option
- Kerosene for remote locations without access to diesel fuel
- Diesel (ultra-low sulfur diesel, ULSD) for standard operation When selecting a fuel, consider the generator’s compatibility and the fuel’s viscosity, which can affect its performance and engine lifespan.
Choosing the Right Fuel for Your Needs
- Biodiesel is an excellent choice for off-grid applications, offering a renewable energy source and lower emissions.
- Kerosene is a good option for generators used in areas with frequent diesel shortages or high fuel costs.
- ULSD diesel is the most common fuel type for diesel generators and offers the best performance and efficiency. When switching between fuels, always refer to the generator’s manual for specific guidance on fuel type, mix ratio, and compatibility.
Preparing and Using Alternative Fuels
Before operating a generator on an alternative fuel, ensure the engine is properly cleaned and prepared to prevent contamination. When mixing biodiesel with diesel, follow the recommended ratio (e.g., 20% biodiesel, 80% ULSD) and use a suitable fuel additive to prevent gelling in cold temperatures. When using kerosene, ensure the generator’s air filter is clean and replace it according to the manufacturer’s schedule to maintain optimal performance.
