Section 14 - Engine Testing - Group 14 Engine Run-In Procedure - Engine Dynamometer (14-02) M11 Page 14-33 Select ‘‘Set Up for Compuchek T ’’ from the ‘‘Special Func- tions Menu’’. The Compulink™ must be left in this mode throughout the test. Future generations of Compulink™ cartridge software will allow Compulink™in the monitor mode while running tests with parameters bypassed. The setup is now completed, and the auto/manual throttle control can be used to control engine speed. Use the active keys to cancel or back up the Compulink™ when the test is complete.
Engine Run-In Procedure - Engine Dynamometer (14-02) Measurements from these indicators and gauges must be observed closely during all phases of the engine run-in period. Engine measurements taken are: Engine speed Engine torque Lube oil pressure Coolant out temperature Fuel pressure Crankcase blowby Fuel rate (using Service Tool, Part No. 3376375) Intake manifold air temperature Intake manifold pressure Turbocharger inlet air temperature Refer to the Engine Dynamometer Worksheet in this sec- tion. NOTE: Intake manifold pressure (turbocharger boost) must be corrected for variances due to intake air temperature.
Use the ‘Boost Pressure Correction Factors’ explained in gine Testing - General Information’’. It is recommended to monitor block coolant pressure during run-in to aid in early indication of a cooling system problem.
