EVALUATING AFTERMARKET DIESEL FUEL ADDDITIVE PACKAGES
Peter M Guerra – VP Technology
1) Will the product measurably affect the cetane number of fuel? (Reduced cetane may cause starting difficulties, especially in cold weather, and can cause knocking and rough engine operation from ignition delay.)?
- FPPF provides many products with cetane improvers. Our 8+ Cetane product is the most potent product on the market today. Our Total Power, Lubricity plus Fuel Power, Agri-Fuel, Liquid Muscle, Auto Truck and our custom formulas all contain cetane improvers. Further the use of all our other products maintain cetane levels and will not reduce cetane ratings as some other additives can.
2) Will product measurably increase the ash content of the fuel? If yes, what is the ash increase in parts per million in the fuel when the additive is blended at the maximum of 0.01 percent ash by weight which may approximate to 100 ppm. High ash levels in the fuel can cause higher rates of ring and piston groove wear that may need to be evaluated by fleets using high ash fuels. High ash can also increase the level of particulate emissions from diesel engines and may need to be evaluated to determine the impact, if any, on emissions requirements that the equipment user is required to meet. High-ash fuel may also reduce the number of miles/hours between service intervals on certain types of after treatment. On other types of after treatment, high ash fuels might reduce the life of after treatment components. Thus, before an additive is used, the impact on after treatment devices should be evaluated.?
- All FPPF fuel additives will not contribute to increased ash content in fuel. Since several of our products actually enhance the combustion efficiencies of the fuel they would potentially reduce the fuel ash content.
