Fuel cut-off valve
13.1a Carburetor engine feedback system - early models
1. Damper; 2. Diaphragm fast idle system; 3. The solenoid valve of the fast idle system; 4. For models with 4-speed manual transmission; 5. Solenoid valve of the ignition distributor; 6. Ignition distributor; 7. Double diaphragm; 8. From the carbon filter; 9. Purge valve; 10. Inlet air temperature sensor; 11. Injection valve; 12. Enrichment valve; 13. Fuel cut-off valve; 14. Throttle position sensor; 15. Additional control valve; 16. Exhaust gas recirculation control valve; 17. Temperature valve; 18. Coolant temperature sensor; 19. Vacuum switch; 20. Catalytic converter; 21. Catalytic converter; 22. Oxygen sensor; 23. Reed valve; 24. Air valve; 25. Additional air valve
1. When the throttle closes abruptly, the remaining fuel in the intake manifold creates a supersaturated fuel mixture. To prevent this, the solenoid valve cuts off the fuel supply (13.1a).
2. The valve also shuts off fuel when the engine is turned off.
Enrichment valve
3. This valve is used to supply additional fuel when the engine is cold or during hard acceleration (13.1a)
Injection valve
4. This valve regulates the composition of the fuel mixture (13.1a). When a richer mixture is required, the valve opens for a longer period of time.

Automatic choke mechanism
1. Heating element; 2. To the air damper relay; 3. Air damper; 4. Breaker; 5. To the intake manifold; 6. Throttle valve; 7. Fast idle cam; 8. Air damper opening diaphragm; 9. Bimetallic spiral
Carburetor feedback system
1. From the carburetor; 2. Diaphragm of low atmospheric pressure compensation system; 3. Atmospheric pressure; 4. Low pressure - high pressure; 5. To the primary chamber of the carburetor; 6. Electromagnetic throttle opening valve; 7. On-Off; 8. Control valve; 9. On-Off; 10. The solenoid valve of the ignition timing system with a cold engine; 11. The solenoid valve of the ignition timing system; 12. On-Off; 13. Distributor; 14. From the carbon filter; 15. Vacuum diaphragm; 16. Damper and throttle opening diaphragm; 17.

Cold air; 31. Hot air; 32. Float chamber ventilation valve; 33. To the carbon filter
5. This valve is used to let in additional air and lean the fuel mixture (13.1b).
Gradual Fuel Cut Solenoid Valve
6. This valve reduces the saturation of the fuel mixture when the engine speed is reduced (13.1b).
Fuel mixture control valve (1988 and 1989 Precis)
7. When the throttle closes abruptly under braking, remaining fuel in the intake manifold results in a supersaturated fuel mixture. To prevent this, the solenoid valve lets in more air.
