8.12. System of compensation of low atmospheric pressure

Models with the carburetor engine
1. The system consists of the compensation valve, the vacuum valve, the control valve and the distributor with the vacuum proofreader.
2. For compensation of low atmospheric pressure in the carburetor the additional amount of air and additional depression on the vacuum proofreader moves.
Models with fuel injection

12.3 Elements of system of compensation of low atmospheric pressure

1 Mixing camera
2 To a branch pipe of the air filter
3 Pressure sensor
4 Ignition lock
5 Electronic control unit
6 Electromagnetic valve


3. On these models pressure sensor together with the electromagnetic valve (12.3) is used  When ignition is included, the sensor periodically checks atmospheric pressure In the rest of the time he watches pressure in an inlet collector
4. The sensor  sends  information  to an electronic control unit which regulates time of opening of injectors according to the atmospheric pressure and pressure in an inlet collector
