Electronically Controlled Feedback Carburetion: Notes

Besides the thermactor air pump system and the dual converter, the Feedback Carburetor Electronic Engine Control (FCEEC) system consists of the following components which interact with the "feedback" portion of the system:

• Model 6500 Feedback Carburetor
• Exhaust Gas Oxygen (EGO) Sensor
• Microprocessor Control Unit (MCU)
• Vacuum Solenoid/Regulator
• Idle Tracking Switch
• Cold Temperature Vacuum Switch

In operation, the FCEEC system has two modes of operation, as determined by the sensors. These are the "Closed Loop Mode" and the "Open Loop Mode".
