🔧 Product Description

This is a genuine Volvo Penta fuel injector from the Fuel System group, part number 1543753. It delivers atomised diesel into the combustion chamber at high pressure and precise timing, and is used across the 16-litre TWD, TID, TAMD and TAD engine series. Each cylinder requires its own injector, so units are commonly replaced as a matched set.

🔌 Function

The injector receives high-pressure diesel from the fuel system and sprays a finely atomised, correctly timed charge into the combustion chamber. Correct spray pattern and opening pressure are essential for clean combustion, rated power output and smooth running.

⚠️ Common Signs of Failure

  • Hard starting, rough idle or misfire on one cylinder
  • Black or white smoke and a noticeable drop in power
  • Knocking or diesel-type hammering noise under load
  • External fuel leakage around the injector body or return line
  • Rising fuel consumption and failure to reach rated speed

🛠️ Service Notes

  • Work clean: cap the fuel connections as they come off and clear the muck out of the injector recess before the injector is withdrawn, so nothing drops into the cylinder
  • Clean the carbon off the seat in the head and out of the bore — a chip of carbon under an injector holds it off its seat and lets combustion gas past
  • Renew the sealing washer, seal ring and O-rings supplied with the injector rather than reusing the old ones, and fit only the type of seal your engine's seat design uses
  • Pull the clamp or holder down evenly to the torque given in the workshop manual for your engine; an over-tightened injector distorts and a slack one blows by
  • Where the engine has electronically controlled injectors, the new injector's calibration code must be programmed into the control unit with Volvo Penta diagnostic equipment, then bleed the fuel system and leak-check before the boat goes back into service
