To the scheme «Entrance» the supply voltage signals of various sensors are input, including those from the sensors of the angular position of the throttle valve of the 1st chamber, the temperature of the incoming air and the position of the idle switch. The signals received from the sensors are converted into digital values.
In the scheme «Treatment» the input values are processed according to fixed programs into analog signals to calculate the output values. After conversion in the output stages, which are power amplification stages, the output signals are given to the servo drives that control the movements of the air damper and the throttle valve of the 1st chamber. At the same time, depending on the operating conditions, the controller provides output signals to the solenoid valve for controlling the vacuum regulator of the ignition distributor and to the main protection relay.
The controller design provides special protection against sudden changes in operating conditions, such as ambient temperature and battery voltage.
Intake air temperature sensor
The intake air temperature sensor is an NTC sensor and is mounted on the intake manifold. The temperature measured by the sensor is fed in the form of an electrical signal to the controller input.
