3 - Solenoid valve with control according to the law of cyclic opening;
4 - Throttle valve block;
R - The pipeline coming from the fuel tank.
Conditions for emptying the absorber
In mixture control mode
1. The coolant temperature is above 50°C.
2. The air temperature is above 15°C.
Absorber emptying solenoid valve
The solenoid valve is mounted above the intake manifold under the cover.
