Folksvagen Sharan/Sharan repair>> The power supply system of the diesel engine and turbocharger>> Safety measures at work on repair of system of injection
At carrying out of repair of the power supply system, irrespective of its volume, the strict image observe cleanliness. The instructions resulted further necessarily observe at carrying out of any works, however, it is paid special attention on safety measures at work in electronic system of injection:
- Always switch off ignition before to disconnect or attach wires of system of injection or the device of a preliminary warming up;

Fig. 470. Elements of the power supply system of the engine in a motor compartment: 1 — the electromagnetic valve of enrichment of a fuel mix at pressurisation; 2 — valve EGR; 3 — the electronic block of a control system of the engine; 4 — an atomizer with the gauge of lifting of a needle; 5 — the relay of an additional element of heating; 6 — the gauge of temperature of an inlet collector; 7 — штекерная колодка the gauge of lifting of a needle; 8 — штекерная колодка the gauge of frequency of rotation of the engine; 9 — the gauge of temperature of a cooling liquid; 10 — штекерная колодка the temperature gauge дозатора; 11 — штекерная колодка запорного the valve of giving of fuel and the valve of the beginning of injection; 12 — запорный the valve of giving of fuel; 13 — дозатор ТНВД; 14 — the gauge of the mass expense of air





- Sometimes the engine is necessary for scrolling a starter (for example, at compression check). Not to allow to the engine to be got, separate a socket штекерной колодки запорного the fuel valve 12 (fig. 470);
- Disconnect wires АБ only at the switched off ignition not to damage system;
- The majority of 470 elements shown on fig. are electronic or electric, therefore to address with them follows with extra care.
Precaution across-the-board measures:
- All works in injection system can be spent only under condition of the strict observance of cleanliness. In the open air repair work in injection system can be spent, only if there is no wind to avoid dust hit in injection system.
- Before dismantle carefully clear all details and knots of a dust;
- The removed details put on a pure surface and cover with their paper or polyethylene. Do not use for this purpose fleecy fabrics;
- Separate and clean the dismantled details which will not be established back;
- Check cleanliness of all established details;
- Do not use compressed air for a purge of other details if connections of fuel system are opened;
- Do not move the car if any elements of fuel system are removed;
- Do not suppose hit of diesel fuel on hoses of system of cooling. Immediately clear hoses if it occurs. Replace polluted by diesel fuel and the hoses damaged thus. ТНВД is not subject to repair. Faulty ТНВД replace or give to repair on HUNDRED.
For adjustment of time of injection ТНВД, and also for its removal and installation it is necessary to have the special tool. Adjustment ТНВД can be spent only on HUNDRED by means of the special equipment.
