High Nitrogen Polyisobutylene Succinimide Dispersing Additives
Ultimate Contaminant Control for Gasoline Direct Injection & Turbocharged Engines
Premium Dispersing Additives for Modern Engines
This product has excellent low-temperature dispersibility and high-temperature stability, with a good solubilizing effect on high-temperature soot. These advanced dispersing additives have a certain alkali storage performance. When used in combination with metal detergents, these dispersing additives not only solve the low-temperature sludge problem of the engine but also reduce the deposition of paint film and carbon deposits on high-temperature engine components. They are mainly suitable for the preparation of medium and high-grade internal combustion engine oils, generally used for diesel engine oils.
Product Introduction
This High Nitrogen PIB Succinimide Dispersant leverages ultra-high nitrogen content (3.5-4.0%) for unparalleled deposit control in low-viscosity gasoline oils. Engineered with optimized PIB molecular weight (Mn=1800), these premium dispersing additives prevent low-speed pre-ignition (LSPI) and turbocharger deposits while maintaining critical fluid stability in extended drain intervals.
Advanced Technologies
- LSPI Suppression Technology™
Reduces pre-ignition events by 98% in 2.0L GDI engines (Ford BRV test validated).
- Turbo Protector System
90% less turbine-side deposits at 950°C (ASTM D6335 modified).
- Ethanol Resilience
Prevents varnish in E85 fuels (5,000-hour dyno proven).
- Friction Stability
Maintains 0.08 friction coefficient after 300h shear (MTM-SLIM test).
- Micro-Oxidation Control
5x reduction in volatile compounds (TG-FTIR analysis).
