A Thermal Enhancer™ has been developed. Primarily, this device functions to increase exhaust gas temperatures to ensure appropriate catalytic heating as an enabler for diesel particulate filter regeneration and nitrogen oxide reduction technologies such as Selective Catalytic Reduction. In addition, this system also gives capability for hydrocarbon dosing as an efficient means for full active regeneration of a diesel particulate filter.

An overview of this system and its functional applications will be given. Focus will be directed toward the design and test methodology that was adopted to develop a combustor.

Results obtained from steady-state, stationary and transient engine dynamometer tests will illustrate the performance benefits and emissions control capabilities of this system.
