The given system during 65 with forces air for final valves at temperature of a cooling liquid of the engine between 15 ° and 35 ° C. Thereof the engine leaves the fulfilled gases enriched by oxygen which promote reburning, and allow the catalyst to get warm faster. Work of system of additional giving of air operates ЭБУ systems "Motronic" through the relay of the secondary pump to the valve of an admission of secondary air and the combined valve.

Fig. 99. Elements of system of additional giving of air: 1 — the air channel in a head of the block of cylinders; 2 — a bolt, 25 Н·м; 3 — a vacuum hose; 4 — an elevating eye; 5 — the holder; 6 — the additional inlet valve */**; 7 — штекерная колодка; 8 — a vacuum hose; 9 — an inlet hose; 10 — the motor of the air pump *; 11 — штекерная колодка; 12 — the holder; 13 — a bolt, 10 Н·м; 14 — a clip for a hose; 15 — a hose under pressure; 16 — the holder; 17 — the combined valve; 18 — a bolt, 15 Н·м; 19 — an O-shaped sealing ring ___________ * The condition of the given detail is traced by the self-diagnostics device. ** The detail condition is traced in «the final conclusion about malfunctions»

After each subsequent start of the engine and until as the engine temperature will reach 85 ° C, the system of additional giving of air (fig. 99) joins with lateness in 20 with and idles the engine during 5 with, thus system work is supervised by the self-diagnostics device.

The condition of details of system of additional giving of air is traced or in «the final conclusion about malfunctions» or if there will be any defect it will be fixed in the registrar of malfunctions. At the reference to memory of the registrar of malfunctions (work is made on HUNDRED), malfunction is easily diagnosed, and then can be corrected.

For some positions (fig. 99 see) following additional explanatories are given:
