## ⚙️ Key Features

-   Precision multi-hole injector nozzle for mechanical diesel fuel-injection equipment
-   Direct Volvo Penta replacement reference for 1543933
-   Injector opening pressure and spray pattern must be set to the applicable engine specification
-   Engine type: Volvo Penta 16-litre six-cylinder diesel

## 🔌 Function

The nozzle atomises high-pressure diesel fuel and sprays it into the combustion chamber in a precise pattern and quantity for each injection event. Correct spray formation is essential for clean ignition, efficient combustion and rated power output.

## ⚠️ Common Signs of Failure

-   Black or smoky exhaust and a strong diesel smell under load
-   Rough idle, misfire or uneven running on one or more cylinders
-   Loss of power, poor throttle response and increased fuel consumption
-   Diesel knock or knocking noise from a single cylinder
-   Hard starting, or fuel dilution and dripping caused by a nozzle that no longer seals

## 🛠️ Service Notes

-   Work scrupulously clean — a nozzle is a precision component with fine machined orifices, and grit carried in on a fingertip or a rag is enough to ruin it
-   Never poke, ream or wire-brush the holes or the seat; if a nozzle is blocked or its spray pattern is disturbed, renew it
-   Cap or plug the open fuel or oil way while the nozzle is out so nothing can drop into the passage
-   Fit new sealing washers, seals or O-rings, clean the seat in the housing and check that seat is undamaged before the nozzle goes back
-   Tighten to the figure and sequence given in the workshop manual for your engine; a nozzle pulled down unevenly or over-tightened will distort and leak
