Check of adjustment of pressure of pressurisation

Check of the electromagnetic valve of restriction of pressure of pressurisation

 PERFORMANCE ORDER

  1. Hose lining: in the beginning check up, whether all hoses are correctly connected to the valve.
  2. Disconnect a valve socket.
  3. Connect an exact ohmmeter to both contacts of a socket of the valve.
  4. The ohmmeter should show 25–35 Ohm, otherwise the electromagnetic valve of restriction of pressure of pressurisation is faulty.
  5. Pressure giving: connect the voltmeter to contact of 1 disconnected socket and to "weight".
  6. Put in action a starter: the voltmeter should show pressure of the accumulator, conductivity in wires is otherwise broken or the relay of the fuel pump is faulty.

By arrow the valve of restriction of pressure of ventilation картера is shown.


Under the mentioned valve of restriction of pressure you see following details: 1 – a vacuum box of the valve of adjustment of pressure of pressurisation; 2 – the valve of switching-off of draught; 3 – the electromagnetic valve of restriction of pressure of pressurisation.
