Fig. 200. The details established near to the case throttle заслонки: 1 — the top part of an inlet collector; 2 — directing a cable; 3 — a bolt, 10 Н·м; 4 — a back right support between the top part of the inlet pipeline and a head of the block of cylinders; 5 — a bolt, 25 Н·м; 6 — a vacuum hose, from the valve of system of ventilation картера; 7 — a ventilating hose, from system of clearing by means of the activated coal; 8 — the T-shaped union; 9 — the case throttle заслонки; 10 — штекерная колодка, black colour, 8 sockets; 11 — a lining, it is necessary to replace; 12 — a support of a cable of a drive throttle заслонки; 13 — a connecting element, 35 Н·м (for valve EGR); 14 — "a mass" cable; 15 — the left back support between the top part of an inlet collector and a head of the block of cylinders

In the case 9 (fig. 200) throttle заслонки various elements are placed. In it it is located throttle заслонка which through the lever of the platen and a cable of a drive throttle заслонки is connected to "a gas" pedal (a pedal of management of fuel giving). Depending on position of a pedal of "gas", the inlet aperture opens or closed. At full loading ("a gas" pedal in a floor) the inlet aperture opens completely.

Potentiometer throttle заслонки

The potentiometer throttle заслонки is built in in ЭБУ. It defines position throttle заслонки at present time and at all working conditions of the engine and hands over this information ЭБУ.

At turn throttle заслонки in reply to movement of a pedal of an accelerator the axis throttle заслонки transfers a rotary motion to the gauge of position throttle заслонки, and on it thus there is a change of pressure of a target signal. Measuring target pressure of a signal, ЭБУ defines current position throttle заслонки, necessary for calculation of a corner of an advancing of ignition and duration of impulses of injection.

Thus, administration of idling stabilisation, deenergizing of giving of fuel or enrichment of a working mix at full opening throttle заслонки is exercised.

The valve of stabilisation of idling provides adjustment of frequency of rotation of a cranked shaft of the engine idling at installation on the car of the hydraulic booster of a steering, an automatic transmission or at the included conditioner. The valve of stabilisation of idling passes through the case throttle заслонки additional quantity of air which passes through the gauge of the mass expense of air that causes receipt in the engine of additional quantity of fuel, allowing to increase capacity of the engine, for maintenance of work of the hydraulic booster of a steering, the conditioner or an automatic transmission.
