Meters and atomises diesel into the combustion chamber at injection pressure and at the correct point in the cycle.

⚠️ Common Signs of Failure

• Rough idle, a knock or a misfire traced to one cylinder
• Black or white smoke and a smell of unburnt diesel
• Hard starting and a drop in power under load
• Fuel leaking back past the injector or weeping at the seat
• Nozzle found coked, dribbling or with a stuck needle on test

🛠️ Service Notes

• Where the installation uses a copper seat washer and sealing ring, renew both rather than refitting the old ones
• Have the set pop-tested together - one bad injector usually means the others are not far behind
• Check the delivery pipe and its cone seats for the same cylinder before condemning the injector
