General
00-0009 Engine Running-in
After the installation of pistons, piston rings or cylinder liners, the engine must be run-in as per the appropriate run-
in schedule.
A thorough running-in is of critical importance regarding the engine's durability and operational reliability.
Use a dynamometer or generator to absorb the power developed during the braking run.
The power from engine to dynamometer must be transmitted through a resilient coupling.
Settings
Set intake-air temperatures before engine according to those given for the engine in its MTU Engine Acceptance
Test Record.
The engine coolant temperature depends on the operating range of the coolant thermostat.
Record the readings for power, fuel, lube oil, coolant, charge air and exhaust at each test point (time, speed and
effective power) of the run-in schedule, and enter them under "Engine Run-in" in the MTU Diesel Engine Factory
Test" record.
Operations
Install engine on test stand.
Connect engine to dynamometer or generator.
Connect intake air, exhaust, coolant and fuel lines.
Connect charge-air coolant line.
Connect oil pressure line and oil temperature sensor
Connect crankcase ventilation line
Connect all measuring hoses and cables
Fill expansion tank up to the max. mark with coolant containing 2% corrosion-
inhibitor oil
Check that fuel in service or supply tank is to specification
Fill up with fresh engine oil to the max. mark.
Check function of engine governor before starting engine
Check function of emergency shutdown system
Start engine
After approx. 1 minute operation at idle, shut down engine and check oil level
Start engine and check idling speed
Check for leaks in the coolant, oil and fuel lines and the crankcase, air-intake and
exhaust gaskets
Run in engine and record measurements in accordance with the running-in
schedule
Check engine speed and brake load
Check injection, temperatures, pressures and speeds at the gauges and compare
with Acceptance Test Record
Measure lube oil temperature before engine
Measure intake depression before turbocharger
Measure exhaust temperature after turbocharger
Measure exhaust pressure (back pressure) after engine
Check exhaust gas colour
