Page 10: Chapter Three Operation Instruction
Chapter Three Operation instruction 1. Fuel, Lubricating oil and cooling water A. Selection of fuel Selecting proper fuel is very important and should be according to the environmental temperature the engine runs in. In the southern hot weather area, light diesel fuel with high cloud point is ok, in the cold northern area, light diesel fuel with low cloud point is necessary. -
Page 11: Selection For Cooling Water
Note: This engine belongs to supercharged diesel engine with high strength and intercooler; therefore, the lubricating oil shouldn’t be lower than grade CF and mixed different grades together. C. Selection for cooling water As for cooling water for the engine, city supply water and clean river water is recommended. -
Page 12: Engine Starting
2. Engine starting A .preparations before starting (1) Check all components and systems to see whether they are in proper order. Check the accessories to see whether they are firmly and reliably connected. Eliminate any abnormality. (2) Check the cooling system and fulfill cooling water. (3) Fill the oil sump until the required oil level is reached. - Page 13 Therefore, as the heating of the engine, increase the speed from650r/min to 1000-1200r/min to warm the engine up. The engine is allowed to operate at full load only when its outlet water temperature exceeds 55℃, oil temperature over 45℃. b. Run-in for the engine For a new engine or an engine after overhaul, the engine must run in for 60 hours before it can be put into full load operation.
- Page 14 bearing clearance. Note: Under very cold situation, exhaust all the cooling water in the engine and its accessories to protect the engine from freezing. The intake and exhaust manifolds of the turbocharged engine must be free of leakage; otherwise, its performance would be lower. Check the tightness of the connecting nuts or bolts and the hose clamps frequently.
