Quick Answer
Biodiesel can be used in dual-fuel generator systems, but it requires careful consideration and specific equipment. The generator must be designed to accommodate biodiesel, and the fuel type should be compatible with the engine. Additionally, the engine's fuel system and combustion chamber must be suitable for biodiesel.
Compatibility and Equipment Requirements
To use biodiesel in a dual-fuel generator system, the engine and fuel system must be compatible. Look for engines rated for biodiesel use, such as those with a B100 rating, which can handle 100% biodiesel. Typically, diesel engines with a biodiesel rating are suitable for blends of 20% biodiesel (B20). Consult the engine manufacturer’s documentation to ensure compatibility.
Fuel System and Combustion Chamber Considerations
The fuel system and combustion chamber must also be designed to accommodate biodiesel. Biodiesel has a higher viscosity and different combustion properties than diesel fuel, which can affect engine performance and fuel efficiency. To mitigate these issues, some engines may require specific fuel system components, such as fuel injectors and pumps, that are designed for biodiesel use.
Blending and Fuel Properties
When blending biodiesel with diesel fuel, the resulting blend must meet specific fuel properties, such as viscosity and flash point. For example, a B20 blend (20% biodiesel, 80% diesel fuel) must have a minimum viscosity of 2.5 cSt at 40°C. The blending process should be done according to the engine manufacturer’s recommendations to ensure proper fuel properties and engine performance.
