rated speed. After unloading, the diesel engine should run at idle speed for 1 to 2 minutes before
shutting down.
5) During operation, pay attention to the following parameters and the related places:
Main oil passage pressure: (350~580) kPa;
Main oil passage temperature at rated condition: (85~105) °C;
Outlet temperature of coolant: ≤98°C;
Exhaust temperature after turbine: ≤550°C;
Intake temperature after intercooler: (50~55)°C
Check the color of exhaust gas to estimate the working performance of fuel injector and the
operating load; if the color is abnormal (i.e., black smoke), stop the engine for troubleshooting.
Notice: Check the diesel engine for water, air and oil/fuel leakages during operation; and if any,
stop the engine for troubleshooting.
6) The operator should acknowledge the following features of the engine:
a. The engine power increases along with the speed, and reaches its rated value at rated speed.
b. Provide the diesel engine with inspection and maintenance at the required time intervals for
routine inspection and technical maintenance.
3.8Operation of diesel engine in winter
1) Fuel: Choose the diesel fuel of proper grade depending to the ambient temperature in winter;
2) Lubricating oil: Choose the lubricating oil of different viscosities based on the season;
3) Coolant: Add anti-freeze into the cooling system, and determine the antifreeze grade and mixture
ratio according to the ambient temperature.
4) Startup: Use starting aid when necessary in winter. After starting the engine, the running speed
and load of diesel engine can be increased only after the oil pressure and water temperature become
normal.
5) Battery: Before the advent of cold season, make sure to check the electrolyte level, viscosity and
unit voltage of the battery; and if the diesel engine is to be withdrawn out of service for a long time
and the ambient temperature is very low, it is recommended to remove the battery and keep it in a
warm room;
6) Shutdown: To stop the engine in cold weathers, unload the engine first, and run it at idle speed
