The measures to prevent diesel engine from flying should include the following:

1. Do not adjust and assemble the high-pressure oil pump arbitrarily. If adjustment is necessary, it should be carried out on a dedicated test bench.

2. Strengthen the maintenance work of the diesel engine fuel pump, adhere to the cleanliness of the gear rod, sector gear, control sleeve and other components of the high-pressure oil pump, and regularly check the fit between the sector gear and control sleeve to ensure correct fit and flexible movement.

3. The oil pan of the air filter should not be filled with too much oil, and the lubricating oil of the speed controller should be replaced regularly. The amount of oil added should not be too much.

4. The quality of fuel and lubricating oil should comply with regulations.

5. For diesel engines that have been parked for a long time, before starting, the relevant parts of the governor should be inspected, and rust should be removed before use.

6. After cleaning the filter with gasoline, be sure to shake off the gasoline and let it evaporate completely in the atmosphere before installing it into the filter.

7. For diesel engines with turbochargers, damaged oil seals should be replaced in a timely manner.
