ENGINEX MARINE is a well-known supplier of YANMAR marine diesel engine spare parts, covering models such as N18, N21, 6N21, 8N21, M200, M220, Z280, M260, N280, N330, HAL, EY18, EY22, EY26, and EY17.
The nozzle sleeve is a critical component installed in the cylinder head to support and locate the fuel injector nozzle. It provides a secure mounting interface while ensuring proper sealing between the injector and cylinder head. The sleeve also helps protect the injector seating area from combustion heat and pressure. Manufactured from high-quality heat-resistant alloy material, it is designed to withstand extreme combustion temperatures, pressure fluctuations, corrosion, and continuous engine operation. Proper nozzle sleeve performance is essential for maintaining accurate fuel injection, efficient combustion, and reliable engine operation in marine propulsion engines, auxiliary engines, and power generation systems.
