Check cylinders for firing by observing exhaust gas temperature. Enter time and RPM at start of each period. Complete readings as soon as engine temperatures have stabilized. Plot oil consumption every ten minutes at 2400 rpm, full load, during run No. 8. Determine that the governor is not limiting the fuel flow. The engine shall not exceed the following maximum allowable temperatures when operating at full power setting, with an air inlet maximum temperature of 120°F (48.9°C), from maximum torque rpm to rated rpm. Air inlet temper- ature shall be measured at the turbocharger compressor inlet. Exhaust gas temperature: 1400°F (760°C) measured at individual cylinder ports with turbocharger inlet air flow restriction less than 1.0 inch of mercury (hg). Exhaust temperature variation between cylinders shall not exceed 250°F (121.1°C) under full load conditions, 350°F (176.7°C) below 2100 rpm. At completion of test schedule, check acceleration, idle speed, and idle oil pressure. Acceleration should be checked with a moderate steady throttle movement. If power is outside limits, check for cause and make correction. Gross corrected horsepower shall be maintained between 1050 and 1080 at 2400 rpm, full rack and full load in accordance with the following graph. 1800 2000 2200 2400 1050 1015 950 850 ENGINE SPEED -- RPM HORSEPOWER LOW IDLE HIGH IDLE 700 -- 750 2600 -- 2660
