Throttle starter required for automatic control of starting, fast idle (when engine warms up), idling, cutting off the fuel supply and stopping the engine. It is an electrovacuum device controlled by the carburetor computer and moves the throttle valve in a certain range of angles. This control range allows the engine to operate from fast idle when warm to full throttle and engine shutdown. The push rod is connected to the throttle lever and can be moved by a vacuum-controlled diaphragm against the spring force. The working pressure is regulated by two solenoid valves. One of these valves is at intake manifold pressure and the other is at atmospheric pressure. Depending on the signal from the control computer, the pressure on the valve diaphragm changes, as well as, accordingly, the position of the pusher.
Adjustment of the throttle trigger must only be carried out by specialist workshops.
