Quick Answer
A generator can run on biodiesel fuel long-term, but it requires careful consideration of the fuel's properties and the generator's design. Biodiesel's viscosity and flash point can be problematic for some generators.
Biodiesel Compatibility
To run a generator on biodiesel long-term, it’s essential to ensure the fuel is compatible with the engine. Most generators are designed to run on diesel fuel, but some may require modifications or special filters to handle biodiesel. A common rule of thumb is to check the generator’s manufacturer specifications for biodiesel compatibility.
Storage and Handling
Biodiesel has a lower flash point than traditional diesel fuel, which can make it more volatile and prone to gelation in cold temperatures. To mitigate this, biodiesel fuel can be blended with a percentage of diesel fuel to improve stability. A typical blend ratio is 20% biodiesel (B20) to 80% diesel fuel. Proper storage and handling practices, such as keeping the fuel in a warm environment and using a fuel additive to prevent corrosion, can also help ensure long-term fuel quality.
Operating Guidelines
When operating a generator on biodiesel, it’s crucial to follow specific guidelines to prevent engine damage. A common recommendation is to start with a small test batch to ensure the fuel is handling properly and doesn’t cause any issues. Additionally, regular maintenance, such as oil changes, is crucial to ensure the engine continues to run smoothly and efficiently on biodiesel fuel.
