🔌 Function

The injector receives a timed high-pressure diesel pulse from the injection pump and atomises the fuel into the combustion chamber.

Common signs of failure:

• Difficult cold starting

• Rough idle or one-cylinder misfire

• Excessive white, grey or black smoke

• Diesel knock

• Reduced engine power

• Injector nozzle drips rather than atomises

• Incorrect opening pressure

• Fuel leaks around the injector body

• Excessive return-fuel flow

📦 Condition

• Genuine used part

• Removed from running engine where applicable

• In good working condition unless otherwise stated
