Design and research on the diesel engine dynamic emission test

摘要

At present, the main use of the steady-state test repeated testing and practical experience combined with inference methods to assess the car with a diesel engine emission performance dynamics, the evaluation method has many shortcoming such as the high cost, low efficiency, certain blindness, and limitations. Based on engine dynamic features built dynamic emission test bench, applying orthogonal design method was tested design, in accordance with the relevant national standard for a domestic vehicle emission diesel engine dynamic performance test, and the test results are analyzed and treatment for the proper assessment of the car with a diesel engine emission performance dynamic approach, which provides a reference value on systematic study.
