1. Incorrect Engine Selection
EN：
Choosing a diesel engine with insufficient power for the application is one of the main causes of overload operation.
For example, if a generator, water pump, or industrial machine requires more power than the engine can provide, the engine will operate under continuous heavy load.
Common situations:
- Engine power is too small
- Equipment requirements increase after installation
- Incorrect power matching
Solution:
Select a diesel engine according to the actual power requirements of the equipment. Leave an appropriate power margin to ensure stable operation.
2. Continuous Heavy Load Operation
EN：
Even a properly sized diesel engine may experience overload problems if it operates continuously at maximum capacity without sufficient rest.
Long-term high-load operation can cause:
- Higher combustion temperature
- Increased oil temperature
- Faster component wear
Solution:
Avoid running the engine at maximum load for extended periods. Regular inspection and maintenance are necessary.
3. Poor Maintenance Condition
EN：
A poorly maintained diesel engine may lose power and require more effort to produce the same output, increasing the risk of overload.
Common maintenance problems:
- Dirty air filter
- Clogged fuel filter
- Poor-quality engine oil
- Cooling system problems
Solution:
Follow a regular maintenance schedule and replace filters and lubricants on time.
