5.4.5.2. The gauge of position throttle заслонки (ДДЗ)
THE GENERAL DATA

The gauge of position throttle заслонки

1. THE GAUGE OF POSITION THROTTLE 3АСЛОНКИ
2. THE FIXING SCREW WITH THE WASHER

ДДЗ it is established on the case throttle заслонки from an opposite side from the drive lever заслонки. ДДЗ it is intended for transformation of an angle of rotation заслонки in an electric signal which moves on input ECU. Position throttle заслонки is considered ECU at definition of duration of a phase of opening of fuel atomizers. At full opening throttle заслонки ECU provides the maximum giving of fuel through all four atomizers, increasing a phase of opening of atomizers or raising frequency of operating impulses. ДЦЗ it is connected to the platen throttle заслонки, movement to which is transferred from an accelerator pedal.

For transformation of an angle of rotation throttle заслонки in an electric signal the potentiometer which 5 V.Pri turn заслонки eat from ECU basic pressure is used electric resistance of a potentiometer and pressure of target signal ДЦЗ changes. On size of a signal of DTSZ ECU counts current position throttle заслонки.
