摘要：
The combustion noise of diesel engines. can be assessed by filtering in-cylinder pressure traces. In this paper, two wavelet-based methods are discussed. It is shown that the statistical properties of a noise meter based on shift-invariant wavelet transforms are improved compared to one that is based on traditional (shift-variant) wavelet transforms. The application of noise metering for pilot injection detection is also presented.
