An open loop engine management system operates without feedback from the engine's performance, relying on pre-set parameters to control fuel delivery and ignition timing. In contrast, a closed loop system uses feedback from sensors (such as oxygen sensors) to continuously adjust these parameters for optimal engine performance and emissions control. This feedback mechanism helps closed loop systems adapt to changing conditions, improving efficiency and reducing pollutants. Overall, closed loop systems are generally more precise and efficient compared to open loop systems.
