As a supplier of silent diesel generator sets, I often receive inquiries from customers about the possibility of running these generators on biodiesel. This is a topic of great interest not only because of the growing concern for environmental sustainability but also due to the potential cost - savings and performance benefits. In this blog, I'll explore whether a silent diesel generator set can run on biodiesel, delving into the technical aspects, advantages, challenges, and considerations.
Technical Feasibility
Diesel engines, including those in silent diesel generator sets, are designed to burn diesel fuel. Biodiesel is a renewable, biodegradable alternative to petroleum - based diesel. Chemically, biodiesel is made up of fatty acid methyl esters (FAME) and is derived from vegetable oils, animal fats, or recycled cooking grease.
Most modern diesel engines, including those in silent generator sets, can run on biodiesel blends without significant modifications. Biodiesel has similar combustion properties to petroleum diesel. It has a high cetane number, which means it ignites easily, a characteristic that is crucial for the efficient operation of a diesel engine.
However, the compatibility of a silent diesel generator set with biodiesel depends on the engine design and the percentage of biodiesel in the blend. For instance, B20, which is a blend of 20% biodiesel and 80% petroleum diesel, is widely accepted and can be used in many diesel engines without major issues. Some engines can even run on B100 (100% biodiesel), but this may require some engine modifications and careful monitoring.
Advantages of Using Biodiesel in Silent Diesel Generator Sets
Environmental Benefits
One of the most significant advantages of using biodiesel is its environmental friendliness. Biodiesel is a renewable fuel source, which means it can be replenished. When burned, biodiesel produces fewer greenhouse gas emissions compared to petroleum diesel. It reduces carbon monoxide emissions by up to 50%, particulate matter by up to 47%, and unburned hydrocarbons by up to 67% [1]. This makes it an ideal choice for users who are conscious of their environmental impact, such as those in eco - friendly facilities or off - grid locations.
Lubricity
Biodiesel has excellent lubricity properties. It can reduce wear and tear on the engine's fuel injection system, including the fuel pump and injectors. This can extend the lifespan of the generator set and reduce maintenance costs over time.
Energy Security
Using biodiesel can contribute to energy security. Since biodiesel can be produced locally from various feedstocks, it reduces dependence on imported petroleum. This is particularly important for regions that are vulnerable to fuel supply disruptions.
Challenges and Considerations
Cold Weather Performance
Biodiesel has a higher cloud point and pour point compared to petroleum diesel. This means that in cold weather, biodiesel can start to solidify or gel at higher temperatures. This can cause fuel filter clogging and engine performance issues. To address this, users may need to use winterized biodiesel blends or install fuel heaters in the generator set.
Storage and Handling
Biodiesel is more prone to oxidation and microbial growth compared to petroleum diesel. It can form gums and sediments over time, which can clog fuel filters and injectors. Proper storage is crucial, including using clean, sealed containers and adding fuel stabilizers.
Engine Compatibility
Although many modern diesel engines can run on biodiesel blends, some older engines or engines with specific components may not be compatible. Rubber seals and gaskets in older engines may be damaged by biodiesel, as it can cause swelling and deterioration. Before using biodiesel, it's important to check the engine manufacturer's recommendations.

Making the Decision
If you're considering using biodiesel in your silent diesel generator set, here are some steps to follow:
- Check Engine Compatibility: Review the engine manufacturer's guidelines to ensure that your generator set can run on biodiesel. If in doubt, contact our technical support team for assistance.
- Evaluate Local Biodiesel Availability: Check the availability and quality of biodiesel in your area. Make sure that the biodiesel meets the relevant standards.
- Consider the Climate: If you live in a cold climate, take into account the cold - weather performance of biodiesel. You may need to use winterized blends or install additional equipment.
- Understand the Costs: Compare the cost of biodiesel with petroleum diesel. While biodiesel may be more expensive in some areas, the long - term benefits, such as reduced maintenance and environmental impact, should be considered.
Conclusion
In conclusion, a silent diesel generator set can run on biodiesel, but there are several factors to consider. Biodiesel offers many advantages, including environmental benefits, lubricity, and energy security. However, it also presents some challenges, such as cold - weather performance and storage issues.
