Description
Technical Overview
The fuel injector nozzle is the final and most critical stage of the fuel delivery system. The 146673-53540 model is manufactured to withstand the extreme pressures and thermal loads of the N18 combustion chamber. By providing a precise spray pattern, this nozzle ensures the engine maintains its power output while minimizing fuel consumption and emissions.
- Compatible Engine Type: Yanmar N18, N18L, and N18AL-UV series.
- Part Number: 146673-53540.
- Component Type: Fuel Injection Valve Nozzle.
- Material: High-grade, heat-resistant alloy steel, precision-hardened for superior durability against needle-seat wear.
Key Features & Performance
- Precision Atomization: Engineered to break down fuel into an ultra-fine mist, ensuring rapid ignition and complete combustion. This results in a cleaner engine and lower Specific Fuel Oil Consumption (SFOC).
- Optimized Spray Geometry: The hole configuration of the 146673-53540 is specifically matched to the N18 piston crown design, preventing “hot spots” and reducing thermal stress on engine components.
- High Wear Resistance: Designed to resist the abrasive effects of Heavy Fuel Oil (HFO) and the corrosive chemicals found in modern marine fuels, extending the time between fuel valve overhauls.
- Consistent Opening Pressure: The needle and seat are lapped to perfection to ensure a sharp “pop” at the designated Valve Opening Pressure (VOP), preventing fuel dripping and subsequent carbon buildup (soot).
