2. If the lubricating oil in the oil pan is added too much, the lubricating oil will easily run into the combustion chamber during the operation of the diesel engine.
3. Long-term low-load operation (less than 40% of rated power), the gap between the piston and the cylinder liner is too large, which makes the lubricating oil in the oil pan easily run into the combustion chamber and mix with the fuel mixture in the cylinder, which changes the normal proportion of the mixture, resulting in incomplete combustion and blue smoke in the exhaust.

Precautions:
1. Before the diesel oil is injected into the diesel engine, it must be allowed to stand for precipitation for more than 72 hours, and then the clean diesel oil with no water and impurities in the upper layer is removed or filtered with silk cloth.
2. Do not fill the fuel tank when the engine is running.
3. Don't smoke when filling diesel oil into the fuel tank, and don't have open flames around.
4. Use clean tubing when refueling, and don't spill diesel oil outside.
6. Finally, clean the spilled fuel, and the materials stained with fuel must be moved to a safe place.
7. Keep the normal water temperature (75°C ~ 95°C). When discharging cooling water, you must first open the radiator cover (it must be opened after the water temperature drops to avoid scalding), and then unscrew the drain switch on the cylinder block.
8. The normal oil pressure at medium speed should be 0.25~0.55MPa.
9, must strictly control the load, not allowed to overload, otherwise it will affect the reliability and service life of diesel engine.
