Some key functions a Manifold Temperature Sensor in a cotton picker include:

1. Monitoring intake air temperature: The sensor continuously monitors temperature of the intake air in the engine’s intake manifold. This information is crucial for the engine control system to adjust the fuel-air mixture and optimize combustion for efficient operation.

2. Improving fuel efficiency: By providing real-time data on the temperature of the intake air, the Manifold Temperature Sensor helps the control system of the cotton picker to adjust the fuel delivery and optimize the air-fuel ratio. This optimization leads to improved fuel efficiency and reduced emissions during operation.

3. Preventing engine damage: The Manifold Sensor plays a role in preventing potential engine damage by detecting temperature abnormalities in the intake air. If the sensor detects excessively high temperatures, it can trigger alerts to the control system, prompting adjustments to prevent overheating and potential engine failure.
