Section E - Engine Identification Engine Specifications M11 Page E-5 Metric [U.S. Customary] Fuel System For performance and fuel rate values, refer to the engine data sheet, or the fuel pump code for the particular model involved. Engine Idle Speed: ........................................................................................................... 650 to 800 RPM Maximum Allowable Fuel Inlet Restriction: With Clean Filter .................................................................................................. 152 mm Hg [6 in Hg] With Dirty Filter ..................................................................................................
254 mm Hg [10 in Hg] Maximum Allowable Drain Line Restriction: .............................................................. 89 mm Hg [3.5 in Hg] Minimum Fuel Pressure: During Cranking ....................................................................................................... 172 kPa [25 psi] 1200 RPM .............................................................................................................. 827 kPa [120 psi] Governed RPM .............................................................................. 1034 to 1241 kPa [150 to 180 psi] Minimum Cranking Speed:
........................................................................................................... 150 RPM Maximum Allowable Fuel Inlet Temperature ............................................................................... 71°C [160°F] Electrical System Minimum Recommended Battery Capacity System Voltage Ambient Temperatures -18°C (0°F) 0°C (32°F) Cold Cranking Amperes Reserve Capacity Amperes 12 Volt 1800 640 1280 480 24 Volt ** 900 320 640 240 Reserve Capacity * Amperes Cold Cranking Amperes * The number of plates within a given battery size determines reserve capacity. Reserve capacity determines the length of time which sustained cranking can occur.
** CCA ratings are based on two, 12 volt batteries in series. A minimum of 6.5 volts at the three pin connector is required to power up the ECM on CELECT™engines.
