NxtGen has developed a simple and elegant diesel aftertreatment system that decouples engine operation from aftertreatment.

The non-catalytic Syngas Generator produces syngas, a mixture of hydrogen and carbon monoxide from engine exhaust and diesel fuel. Syngas is used to regenerate a lean NOx trap (LNT) by converting trapped NOx into nitrogen and water. Syngas enables active diesel particulate filter (DPF) regeneration through combustion at lower temperatures than diesel fuel resulting in lower fuel consumption. A Control Unit contains proprietary algorithms, developed by NxtGen, for optimizing aftertreatment system regeneration.

NxtGen's technology is a long-term platform for engine system improvements:

• Provides another 'lever' to improve fuel economy through engine recalibration
• Assists lean combustion for improved fuel economy and reduced emissions (diesel and gasoline)
• Enables idle reduction and vehicle electrification by providing syngas as a fuel for solid oxide fuel cell auxiliary power units.

NxtGen's syngas aftertreatment technology is modular and adapts to multiple system configurations. For retrofit system manufacturers, NxtGen now offers an active Regeneration Diesel Particulate Filter system and is developing a combined LNT - DPF system.  For original equipment manufacturers, NxtGen has developed a compact system for use with light duty diesel applications.
