🔌 Function

Meters and atomises diesel fuel into the cylinder at the specified pressure and timing.

⚠️ Common Signs of Failure

  • The engine becomes difficult to start or idles unevenly
  • The affected cylinder misfires or produces reduced power
  • Exhaust smoke, diesel knock or fuel consumption increases
  • Fuel leaks around the injector body or high-pressure connection
  • Testing shows poor atomisation, incorrect opening pressure or an uneven spray pattern

🛠️ Service Notes

  • Have the removed injector pressure-tested rather than assuming it is at fault, as low compression on the same cylinder gives similar symptoms
  • Clean the injector bore and renew the seat seal before fitting; the seal is a separate number
