| Component Type | Nozzle Holder Assembly (Injector) | Holds the nozzle and opens at a set pressure. |
| Engine Application | Mitsubishi S12N | Used in generators, marine propulsion, and heavy industrial equipment. |
| Injection Pressure | 220 - 290 kg/cm² | This is a wide range. Older engines are usually on the lower end, while newer, higher-performance variants are higher. |
| Nozzle Type | Multi-hole (Typically 4 to 8 holes) | Hole diameter is usually measured in hundredths of a millimeter (e.g., 0.29mm to 0.40mm). |
| Nozzle Hole Diameter | 0.29 mm - 0.40 mm (approx) | This depends on the engine's power rating and specific fuel mapping. |
| Spray Angle / Cone Angle | 150° - 160° (approx) | The angle at which fuel is sprayed into the pre-combustion chamber or directly into the cylinder. |
| Housing Material | High-grade Alloy Steel | Designed to withstand high pressure and heat. |
| Mounting Torque (Holder) | 50 - 70 N·m (approx) | Crucial: Always use the manual for exact torque to avoid distortion. |
| Mounting Torque (Nozzle Nut) | 40 - 60 N·m (approx) | Retains the nozzle inside the holder body. |
