Diesel to WVO / SVO Conversion Fuel Starvation
If you are considering converting your diesel vehicle to run on waste vegetable oil (WVO) or straight vegetable oil (SVO), it is important to understand the potential issues that may arise during the conversion process. One common problem faced by many enthusiasts is fuel starvation, which can cause significant damage to the engine if not addressed properly.
Understanding Fuel Starvation
Fuel starvation occurs when the fuel supply to the engine is interrupted or insufficient to meet its requirements. This can result in engine misfires, loss of power, and even complete engine failure. During a diesel to WVO / SVO conversion, fuel starvation can be a real challenge due to the differences in viscosity and composition between diesel fuel and vegetable oil.
When converting to WVO or SVO, it is important to consider the following factors that contribute to fuel starvation:
- Fuel Filter Clogging: Vegetable oil contains impurities and sediments that can clog the fuel filter more quickly than diesel fuel. Regularly inspecting and cleaning the fuel filter is crucial to prevent fuel starvation.
- Fuel System Modifications: Converting a diesel fuel system to accommodate WVO or SVO requires specific modifications, such as installing a separate tank, fuel heater, and additional filters. Inadequate modifications can lead to fuel supply issues.
- Temperature Changes: Vegetable oil has a higher thickening point compared to diesel fuel, meaning it can solidify in colder temperatures. This can restrict fuel flow, causing fuel starvation. Employing a fuel heater or using fuel additives can help prevent this issue.
Preventing Fuel Starvation
To ensure a smooth and successful conversion from diesel to WVO / SVO, it is essential to take preventive measures to avoid fuel starvation. Here are some tips to help you prevent this problem:
1. Proper Fuel Filtration and Maintenance
Invest in high-quality fuel filters designed to handle WVO or SVO. Regularly inspect and replace the filters to prevent clogging and maintain proper fuel flow. Additionally, consider installing additional filters or a centrifuge to further remove impurities from the vegetable oil.
2. Adequate System Modifications
Work with a reputable conversion specialist, like Grafco Electric, who understands the intricacies of converting diesel engines to run on vegetable oil. They will ensure that the necessary modifications are made to your fuel system, including installing a separate tank, fuel heater, and additional filters. This will help optimize fuel flow and minimize the risk of fuel starvation.
3. Fuel Heating and Insulation
Preventing fuel solidification in colder temperatures is crucial to avoid fuel starvation. Install a fuel heater to warm the vegetable oil to a suitable temperature before it enters the engine. Additionally, insulate fuel lines and tanks to retain heat and prevent temperature-related fuel flow issues.
4. Regular System Inspections
Maintaining a regular inspection schedule will help you identify and address potential issues before they lead to fuel starvation. Check fuel lines, filters, and the entire fuel system for leaks, blockages, or any signs of degradation. Promptly address any issues to ensure proper fuel supply.
5. Fuel Additives and Blending
Using fuel additives specifically designed for vegetable oil can improve its flow characteristics and prevent fuel starvation. Consider using additives that reduce viscosity, inhibit gelling, and enhance overall fuel performance. Blending WVO or SVO with a small percentage of diesel fuel can also improve ignition and combustion, helping to prevent fuel starvation.
In Conclusion
Converting your diesel vehicle to run on WVO or SVO can be a rewarding decision, both for environmental and economic reasons. However, fuel starvation is a potential challenge that should not be overlooked. By taking the necessary precautions and following proper conversion techniques, you can successfully prevent fuel starvation and enjoy the benefits of running your vehicle on vegetable oil.
