SEBU8311-01 55 Maintenance Section Refill Capacities • “ASTM D975”, Grade 1D S15, and Grade 1D S500 • “JP7 (MIL-T-38219)” • “NATO F63” Note: JP7 and NATO F63 can only be used if the sulfur level meets the specifications that are listed in tables 37 and 38. An analysis of a sample of fuel must be conducted in order to check the sulfur level. Group 3 Specifications (Aviation Fuels) This group of fuel specification must be used only with the appropriate fuel additive. This fuel WILL reduce engine life and performance. • “NATO F34 (MIL-DTL-83133E)” • “NATO F35 (MIL-DTL-83133E)” • “NATO JP8 (MIL-DTL-83133E)” • “NATO F-44 (MIL-DTL-5624U)” • “NATO JP5 (MIL-DTL-5624U)” • “Jet A (ASTM D1655)” • “Jet A1 (ASTM D1655)” Note: All the above fuels can ONLY be used if the sulfur level meets the specifications that are listed in tables 37 and 38. An analysis of a sample of fuel must be conducted in order to check the sulfur level. Note: These fuels are only acceptable provided that these fuels are used with an appropriate fuel additive. These fuels must meet the requirements that are stated in tables 36, 37 and 38. Fuel samples should be analyzed for the compliance. These fuels MUST NOT exceed lubricity wear scar diameter of 0.46 mm (0.0181 inch). The fuel lubricity test must be performed on a HFRR, operated at 60 °C (140 °F). Refer to “ISO 12156-1 ”. Fuels must have minimum viscosity of 1.4 centistokes that is delivered to the fuel injection pump. Fuel cooling may be required in order to maintain minimum viscosity of 1.4 centistokes that is delivered to the fuel injection pump. Group 4 Biodiesel Biodiesel is a fuel that can be defined as mono-alkyl esters of fatty acids. Biodiesel is a fuel that can be made from a variety of feedstock. The most commonly available biodiesel in europe is Rape Methyl Ester (REM). This biodiesel is derived from rapeseed oil. Soy Methyl Ester (SME) is the most common biodiesel in the United States. This biodiesel is derived from soybean oil. Soybean oil or rapeseed oil are the primary feedstocks. These fuels are together known as Fatty Acid Methyl Esters (FAME). Raw pressed vegetable oils are NOT acceptable for use as a fuel in any concentration in compression engines. Without esterification, these oils gel in the crankcase and the fuel tank. These fuels may not be compatible with many of the elastomers that are used in engines that are manufactured today. In original forms, these oils are not suitable for use as a fuel in compression engines. Alternate base stocks for biodiesel may include animal tallow, waste cooking oils, or a variety of other feedstocks. In order to use any of the products that are listed as fuel, the oil must be esterified. Note: Engines that are manufactured by Perkins are certified by use of the prescribed Environmental Protection Agency (EPA) and European Certification fuels. Perkins does not certify engines on any other fuel. The user of the engine has the responsibility of using the correct fuel that is recommended by the manufacturer and allowed by the EPA and other appropriate regulatory agencies. Recommendation for the use of biodiesel The neat biodiesel must conform to “EN14214” or “ASTM D675” regulations. A maximum of 10% mixture of biodiesel can be used in mineral diesel fuel. The mineral diesel fuel must conform to “EN590”, “ASTM D975” or “BS2869 Grade A2” regulations. In North America, biodiesel and mixtures of biodiesel must be purchased from the BQ9000 authorized manufacturers and BQ9000 certified distributors. In other areas of the world, the use of biodiesel that is authorized and certified by an appropriate biodiesel quality body is required. Note: When biodiesel, or any blend of biodiesel is used, the user has the responsibility for obtaining the proper local exemptions, regional exemptions, and/or national exemptions that are required for the use of biodiesel in any Perkins engine that is regulated by emissions standards. Biodiesel that meets “EN14214” is acceptable. The biodiesel must be blended with an acceptable distillate diesel fuel at the maximum stated percentages. However, the following operational recommendations must be followed: |
