Applications

• Hydrogen internal combustion engine development：Use low-reactivity specialized lubricants to suppress pre-ignition at the source, preventing super-knock damage.
• Hydrogen power systems：Improve hydrogen engine power density and reliability by suppressing pre-ignition, advancing practical hydrogen power systems.
• Engine lubrication：Reduce the auto-ignition tendency of lubricant components to eliminate hotspots that trigger pre-ignition.
• ICE components：Improve interaction between combustion chamber components and lubricants to reduce surface hotspot formation.
