The interaction of system components

At a minimum speed mode (850 1 \ minute) idling microswitch xcontacts are open, because the throttle pedal flap while fully released (recessed plunger). However, through the winding solenoid current flows through the electrical connection terminals 1 and 2 control unit. If you increase the speed of the engine crankshaft pressing the throttle pedal to 1 \ 1500 rpm or more, and then the pedal is fully released, the xcontacts microswitch is tripped, and electrical connection terminals 1 and 2, the control unit will also be open. At the same time winding the solenoid valve is de-energized and the pawl EPHH shuts off the fuel to the engine. Under these conditions, the engine is running on the mode of forced idle. When fully released throttle pedal duration of treatment overrun with open transmission very low (1-2), while driving a car and engine braking can be amount to several tens of seconds.
