Dynamometer Test. With the engine connected to the dynamometer and test cell in accordance with step a,
above, conduct a dynamometer test as follows:
(1)
Prime the lubrication system if necessary, start the engine, and run at phase 1, Table 12-1, until both
the oil and coolant temperatures reach at least 160'F (71 °C).
(2)
Gradually increase the speed to 1800 rpm, and the horsepower to 1200 (895 KW) and maintain these
settings for 5 minutes.
(3)
During the test, continually monitor all instruments, and record all data on the test log. All test data shall
be in accordance with Table 12-2.
(4)
At the end of the test, return the engine to idle speed and no load for at least 5 minutes before shut-
down.
(5)
Top-up the crankcase with lubricating oil, total the amount of oil used during the run, and calculate the
oil consumption by dividing the quantity of oil used by the elapsed time of the run in hours. In general,
the oil consumption should not exceed 0.66 quarts (0.62 L) per hour. During run-in, however, oil
consumption in excess of this amount is acceptable provided the crankcase pressure does not exceed 18
inches (457 mm) H20 at the end of the run.
(6)
Remove the engine from the dynamometer and test cell, and install it in the generator set in accordance
with Chapter 2.
SECTION lIl. INSPECTION
12-4. GENERAL Athorough inspection of the generator set shall be conducted to ensure that workmanship and materials
