Repair Sharan/Sharan Volkswagen>> VR6 engine>> System of production of the fulfilled gases>> System of additional supply of air
This system during 65 with forces air for final valves at temperature of cooling liquid of the engine between 15 ° and 35 ° C. Thereof the engine leaves the fulfilled gases enriched with oxygen which promote reburning, and allow the catalyst to get warm quicker. Work of system of additional supply of air Motronic system EBU via the relay of the secondary pump to the valve of an admission of secondary air and the combined valve operates.
After each subsequent start of the engine and until as the temperature of the engine will reach 85 ° C, system of additional supply of air (fig. 99) joins with lateness in 20 with and idles the engine during 5 with, thus work of system is supervised by the self-diagnostics device.
The condition of details of system of additional supply 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 appeal to memory of the registrar of malfunctions (work is made on HUNDRED), malfunction is easily diagnosed, and then can be corrected.
For some positions (see fig. 99 ) the following additional explanations are given:
- in an air line of 1 head of the block of cylinders additional air is forced;
- the elevating eye 4 is screwed at the left on a head of the block of cylinders;
- the valve of supply of additional air is twisted in a collar 5;
- the shtekerny block 7 is put on the inlet valve (black color);
- the vacuum hose 8 is attached between the top part of the inlet pipeline and the distributive fuel highway;
- the inlet hose 9 goes from the top part of the air filter. Its connection should be tight, without intake of air;
- the shtekerny block 11 belongs to the motor of the air pump. It black color also has two shtyrkovy conclusions;
- the holder 12 holds the motor of the air pump. It is screwed up in an air inlet of the fan of cooling;
- the shlangovy collar 14 fixes an inlet hose;
- the pressure head sleeve 15 fastens between the engine of the pump 10 and the combined valve 17;
- the holder 16 fixes the combined valve on a directing tube щупа for check of level of oil;
- always change the About-shaped ring 19.
