Abstract
Conclusion and Future Activities: 1. This testing showed that for the majority of test conditions the JM ACRT system was very effective in reducing number and surface area concentrations of aerosols emitted by tested engine. At TC&HS conditions, the hydrocarbon injection resulted in relatively high concentrations of nucleation mode aerosols. 2. The system reduced CO emissions at all test conditions. 3. For TC&HS and HI conditions, the "System Out" NO2 emissions were similar to the corresponding "Engine-Out" emissions. However, at LI conditions, the "System Out" NO2 concentrations were substantially higher than the corresponding "Engine Out" NO2 concentrations. 4. NIOSH and Vale are planning to reevaluate the system after approximately 2000 hours in operation.
