Summary:

This paper describes the development of an exhaust ThermalEnhancer using an airless nozzle fuel system. The purpose of theThermal Enhancer is to increase diesel engine exhaust gastemperatures to a level where catalytic heating can be used forDiesel Particulate Filter regeneration. The system can also be usedto achieve adequate temperatures for NOx reduction, employingtechniques such as Selective Catalytic Reduction.The Thermal Enhancer is used to increase exhaust gastemperatures at conditions that would otherwise be too cold foreffective catalyst operation. These conditions include idle andlow-load operation. The airless-nozzle fuel system is necessary forengines that do not have a compressed-air system.Performance data, including hydrocarbon slip as a function ofThermal Enhancer outlet temperature are presented at steady stateconditions. Pressure loss as a function of engine speed indicatesit is less than 1 kPa at the maximum exhaust flow rate. ThermalEnhancer outlet temperature as a function of engine speed isgreater than 300°C across the engine map. Data are measured from anengine test cell configuration
