1. When the throttle valve is suddenly closed, the fuel remaining in the intake manifold creates a supersaturated fuel mixture. To prevent this, the solenoid valve stops the fuel supply (13.1a).
2. The valve also stops the fuel supply when the engine is turned off.
Enrichment valve
3. This valve is used to supply additional fuel when the engine is cold or when accelerating rapidly (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.

5. This valve serves to admit additional air and deplete the fuel mixture (13.1b).
Fuel gradual shut-off solenoid valve
6. This valve reduces the saturation of the fuel mixture when the engine speed decreases (13.1b).
Fuel mixture control valve (1988 and 1989 Precis)
7. When the throttle valve is closed abruptly during braking, the remaining fuel in the intake manifold causes a rich fuel mixture. To prevent this, the solenoid valve lets in additional air.
