| 摘要： | This study included engine cell and vehicle tests. The engine cell tests are aimed at determining NOX reduction using the US transient and OICA emissions test cycles. These cycles will be included in future US HD emissions standards. The vehicle tests will show urea-SCR system performance during real-world operation. These tests will prove that the technology can be successfully implemented and demonstrated over-the-road. The program objectives are to: (1) apply urea-SCR to a US HD diesel engine; (2) determine engine cell emissions reduction during US-transient and OICA cycles; (3) apply urea-SCR to a US HD diesel truck; and (4) determine NOX reduction and urea consumption during over-the-road operation. |
