Answer :
Final answer:
To ensure proper ignition in a tractor's internal combustion engine, spark plugs must be changed regularly. They are essential for igniting the air-fuel mixture for engine operation. Neglecting spark plug maintenance can lead to engine performance issues.
Explanation:
Regular Maintenance for Internal Combustion Engines
To create the required ignition in an internal combustion engine, especially in a tractor, it is important to regularly change the spark plugs. Spark plugs are critical components that ignite the air-fuel mixture in the engine's cylinders, allowing the engine to function efficiently.
Over time, spark plugs can wear out or become dirty, which can lead to misfires, rough idling, or reduced engine performance. Regular maintenance involves checking and replacing spark plugs as necessary, typically every 30,000 to 100,000 miles, depending on the type of spark plug used and the engine's specifications.
Other Engine Components
- Oil pans contain oil and need to be managed, but they do not directly affect ignition.
- Compressor valves relate to air intake but are not directly responsible for ignition.
- Piston bearings are crucial for engine function, but they are not related to the ignition process.
Therefore, the correct answer to the question is option OB. spark plugs.
