Combustion Mechanical Breakdown: A Comparison of the Multiple Regression Method versus the Coherence Method for a HSDI Diesel Powertrain 2011-26-0035
In the automotive industry there are now several methodologies available to estimate the Combustion Mechanical Breakdown (CMB) of engine radiated noise. This paper compares the results of two different CMB analysis methodologies (multiple regression vs. coherence) performed on a HSDI diesel powertrain installed in an Engine Noise Test Cell (ENTC) and highlights the specific differences in the way each method defines combustion and mechanical noise.
