Tractor noise consists of several individual sound sources, mainly combustion noise, exhaust noise, fan noise, and mechanical noise. To control tractor noise, drivers should pay attention to the following:
1. Ensure the tractor operates in good technical condition at all times.
2. Ensure the integrity and reliability of the tractor's working parts. Pay special attention to the proper installation of the exhaust pipe, as most exhaust pipes have mufflers that significantly reduce noise.
3. Prevent loose parts, as loose parts will cause vibration.
4. Perform proper tractor maintenance and inspection. Add qualified lubricating oil and grease as specified to prevent poor lubrication of moving parts, which can lead to dry or semi-dry friction and increased noise.
5. Maintain good clearance between moving parts. Drivers must assemble or adjust according to technical requirements.
6. Do not arbitrarily change the fuel supply. Increasing the fuel supply will cause incomplete combustion of fuel injected into the cylinder, wasting fuel, polluting the air, and increasing tractor noise.
The fuel injection advance angle must be adjusted accurately. The accuracy of the fuel injection advance angle adjustment directly affects not only the tractor's power output but also its noise level. We often encounter tractors that produce particularly loud exhaust noises, frequently accompanied by "pop, pop" sounds; this is caused by an excessively large fuel injection advance angle.
