Description
Technical Overview
The 16/24 engine is known for its compact design and efficiency. The LTO-U9089a/E nozzle variant is specifically developed to handle the thermal and mechanical loads of modern marine fuels while maintaining a clean spray pattern.
- Compatible Engine Type: MAN 16/24 (all configurations).
- Designation: LTO-U9089a/E (LTO: Low Temperature Oxidation resistant).
- Application: Auxiliary engines and Marine GenSets.
- Material: High-performance alloy steel with advanced heat treatment for maximum hardness and durability.
Key Features & Performance
- Enhanced Oxidation Resistance (LTO): Specifically designed with materials that resist low-temperature oxidation and carbon deposits, preventing nozzle tip “carbon trumpets” and ensuring a consistent spray over time.
- Optimized Injection Geometry: The internal needle and spray hole geometry (U9089a/E spec) are calibrated to ensure the perfect fuel-to-air ratio, which is vital for the 16/24’s rapid load response.
- Reduced Fuel Consumption: Precision atomization leads to more complete combustion, directly lowering the Specific Fuel Oil Consumption (SFOC) and reducing soot buildup.
- High Pressure Durability: Built to withstand the high injection pressures required for compliance with IMO Tier II and Tier III emission standards.
