2 diesel engine is the world's first diesel engine to comply with global exhaust gas regulations, including Japan's Post New Long-Term Regulations and Europe's Euro6, without the need for an expensive nitrogen oxide (NOx) aftertreatment system, such as the urea selective catalytic reduction (SCR) system or Lean NOx Trap (LNT) catalyst.
Additionally, its newest low cost Lean NOx Trap (LNT) system offers the simplest and most economical diesel NOx emission reductions on a cost-per-ton of emissions basis, particularly on the millions of older, in-use heavy/mid-duty stop-and-go city-driven diesel vehicles and off-road pieces of equipment.
This technology can also be applied to regeneration of diesel particulate filters and lean NOx traps in various global applications.

According to HydrogenSource, the reformer, which is based on the company's patented catalytic partial oxidation (CPO) technology for generating hydrogen on board vehicles, converts a "small" portion of diesel fuel into hydrogen-rich gas that can be utilized for regenerating lean NOx traps (LNTs), which capture the pollutant on a catalyst surface.
The opposite strategy of reducing NOx significantly with the aftertreatment would have meant either SCR (selective catalytic reduction) using urea as a reductant, or a lean NOx trap technique.
Developing acceptable procedures will be a complex process," Bartley said, adding that at least four different aftertreatment systems must be considered: the diesel oxidation catalyst (DOC), the diesel particulate filter (DPF), the lean NOx trap (LNT) or NOx adsorption catalyst (NAC), and the urea (ammonia) selective catalytic reduction catalyst (SCR).
Steward noted that potential projects include the development of emission-reduction devices and strategies, such as model-based controls, lean NOx trap regeneration and control strategies with a flexible fuel and valve-actuation system engine.
