Specifications

Open the throttle to obtain speed at which maximum
horsepower is developed and adjust the dynamometer
load to achieve 75 percent of rated fuel pressure or 75
percent fuel rate on CELECT™ engines. Operate the en-
gine at this speed and load level for 3 minutes.
Check all gauges and record the data.
NOTE: Do not proceed to the next step until blowby is stable
within specifications.
Maintain maximum horsepower RPM and advertised
horsepower, and increase the dynamometer load until
100 percent rated fuel pressure or 100 percent fuel flow
is developed. Operate the engine at this speed and load
level for 5 minutes or until the blowby becomes stable
within specifications.
Check all gauges and record the data.
Increase the dynamometer load until the engine speed
reduces to the engine’s torque peak RPM.
Operate the engine at torque peak RPM for 7 minutes.
Check all gauges and record the data.
Reduce the dynamometer load until the engine speed
increases to the engine’s maximum horsepower RPM.
Operate the engine at maximum horsepower RPM for 5
minutes.
Check all gauges and record the data.
Compare the readings to the specifications listed in the
previously mentioned publications.
