LGC Lean GDI (Gasoline Direct Injection) Catalysts

The patented BASF ECMS Lean GDI (Gasoline Direct Injection) Catalyst technology provides the additional NOx (nitrogen oxides) removal required to treat exhaust from Lean GDI engines.

These engines use lean combustion (excess of air) to deliver improved fuel economy. However, NOx exhaust emissions can increase and are a challenge to remove under these lean operating conditions.

The Lean GDI catalyst is designed to operate under lean conditions and can be placed after the TWC catalyst to provide additional NOx conversion. The benefits include:

  • Exceptionally high thermal stability

  • High NOx removal activity at high temperature

  • High NOx storage capacity
