GENERAL INFORMATION

Fuel pressure

Fuel pressure on engines without turbocharger (in the idling mode):
  – the vacuum hose, is established on the regulator
1,8 – 2,2 bars
  – the vacuum hose, is removed from the regulator
2,2 – 2,7 bars
Fuel pressure on engines with a turbocharger (in the idling mode):
  – the vacuum hose, is established on the regulator
2,4 – 2,8 bars
  – the vacuum hose, is removed from the regulator
2,7 – 3,1 bars
Pressure created by the fuel pump
2,1 bars
Resistance of a fuel nozzle:
