39、solete. Added Grades 1C(MP) and 2C(MP) for use at Melrose Park Engineering APPENDIX GENERAL INFORMATION (NOT A REQUIREMENT) A.1 CHARACTERISTICS and APPLICATIONS These fuels are intended for use as follows: A.1.1 Factory Fill or Service Accumulation Fuel A.1.1.1 Grade 1 Winter Fuel: Factory Fill or S
40、ervice Accumulation test fuel, for use at low ambient temperatures of +10 to -25F (-12 to -32C). For temperatures below -25F (-32C), a fuel meeting the requirements of Commercial Item Description (CID) AA-52557, Low Temperature Diesel Fuel Blend F-65 should be used. The Grade 1 diesel fuel is normal
41、ly provided with a sulfur content of 7 - 15 parts per million (ppm). A.1.1.1.1 Grade 1C(MP) is a winter fuel used by Engine Group at Melrose Park Engineering. A.1.1.1.2 Grade 1C Winter Fuel: Factory Fill or Service Accumulation test fuel for use at the same ambient temperature ranges as the Grade 1
42、fuel but, having an ultra low sulfur content of 7-15 ppm. At this time the general availability of this Grade 1C fuel is quite limited. A.1.1.2 Grade 2 Summer Fuel: Factory Fill or Service Accumulation test fuel for normal ambient temperature operations. This fuel, with or without minimum aromatics
43、content, will meet EPA requirements for Service Accumulation tests. The Grade 2 diesel fuel is normally provided with a sulfur content of 7-15 parts per million (ppm). A.1.1.2.1 Grade 2C(MP) is a summer fuel used by Engine Group at Melrose Park Engineering. A.1.1.2.2 Grade 2C is a Factory Fill or Se
44、rvice Accumulation test fuel for use at the same ambient temperatures as the Grade 2 fuel but, having an ultra low sulfur content of 7 - 15 ppm. A.1.2 Emission Certification Fuel A.1.2.1 Grade 2: This fuel will meet EPA requirements for exhaust emission testing. The fuel is available in an ultra low sulfur version with sulfur content at 8-14 ppm.
