Some key functions of a Fuel Temperature Sensor in a cotton picker include:

1. Monitoring fuel temperature: The sensor continuously monitors the temperature of the fuel in the fuel system of the cotton picker. This information is important for the engine control system to adjust the fuel delivery and optimize combustion for efficient operation.

2. Preventing fuel system issues: By detecting the temperature of the fuel, the Fuel Temperature Sensor helps to prevent issues such as fuel evaporation, fuel gelling, or fuel line freezing that can occur when the fuel is too hot or too cold. This ensures that the fuel remains in a suitable condition for proper engine performance.

3. Improving fuel efficiency: Maintaining the correct fuel temperature can also have an impact on fuel efficiency. The Fuel Temperature Sensor allows the control system of the cotton picker to adjust the fuel delivery based on the temperature of the fuel, optimizing the combustion process and improving fuel efficiency.
