In addition to developing low light-off catalyst materials, a novel dual-functional catalytic conversion device with heat exchange function is designed to address the emission challenges for CO, HC and NOx under low temperature combustion because of its ability to regulate catalysts temperatures, especially during cold engine starts (which attributes to 80% unburned hydrocarbons). As part of the engine waste heat recovery system, fuel efficiency can also be improved significantly (Cummins Supertrucks as an example). With precise temperature control, the technology can also prevent catalysts from reaching extreme temperatures during regeneration causing long-term durability concerns.
