Marine Cylinder Oil Additive Package
Número CAS: N/A (formulated package)
Marine cylinder oil additive package for total-loss lubrication of two-stroke crosshead diesel engine cylinder liners. Delivers very high TBN reserve (typically 25-100 mgKOH/g in finished oil) to neutralize sulfuric acid produced by combustion of high-sulfur or low-sulfur marine fuels. Multiple grade tiers (BN 25, 40, 70, 100) match the sulfur content of the bunker fuel: low-sulfur compliant fuel (VLSFO ≤0.5% S) → BN 25-40; high-sulfur fuel (HSFO, 3.5% S) used with scrubbers → BN 70-100.
Especificaciones Técnicas
| appearance | Brown viscous liquid |
| sulfated ash | 8-13 wt% (grade-dependent) |
| flash point (COC) | ≥220 °C |
| recommended base oil | Bright stock or Group I SN 600 + bright stock blend, SAE 50 cut |
| kinematic viscosity (100°C) | 120-180 mm²/s (in finished SAE 50 cylinder oil) |
| total base number (TBN) in finished oil | 25 / 40 / 70 / 100 mgKOH/g (grade-dependent) |
Aplicaciones
- Cylinder lubrication of two-stroke crosshead marine diesel engines (MAN B&W ME/MC, Wärtsilä-Sulzer RT/RTA series)
- High-BN grades (70/100) for high-sulfur fuel oil operation with on-board scrubber
- Low-BN grades (25/40) for IMO 2020 compliant VLSFO and LSMGO operation
- Mid-range grades (40-55) for dual-fuel or scrubber-bypass operating modes
- Feed rate typically 0.6-1.5 g/kWh, controlled by engine load and fuel sulfur content
Características Principales
- BN tiers (25/40/70/100) cover the full range from VLSFO compliant fuel to high-sulfur scrubber operation
- Strong detergency to keep piston ring grooves and lands clean under combustion deposit load
- Optimized for total-loss application — no recycling, dosed by cylinder lubricators
- Compatible with both MAN B&W and Wärtsilä-Sulzer OEM cylinder oil approval lists
