In CI engines, injector spraying into the combustion chamber has extreme importance in fuel
atomization and knocking control in the CI engines. Knocking and malfunction of engines …

Time–frequency transforms, including wavelet and wavelet packet transforms, are generally
acknowledged to be useful for studying non-stationary phenomena and, in particular, have …

The short-term-Fourier-transform (STFT) is used to identify different sources of IC engine-
block vibration from single-point acceleration measurements taken with a commercial knock …

A new method of machinery fault diagnosis based on wavelet analysis is presented. We
introduce an extension to Mallat and Zhang's matching pursuit for machinery diagnosis is …

The high-frequency components of engine block vibration signals during misfire and normal
combustion show clear differences of duration and scale by wavelet analysis-continuous …

In the present work, the Discrete Wavelet Transform (DWT) has been applied on the
vibrational signals acquired by an accelerometer placed on the cylinder block of a Spark …

The Wavelet Transform (WT) has been developed two decades ago, and has since then
been put to use in an increasingly wide array of applications. The WT provides a time-scale …

In this paper, a review is given of some of the modern methods in the detection of knock in
internal-combustion engines and some comparisons are made between these methods and …

The short-term Fourier-transform (STFT) is used to identify different vibration sources of
internal combustion engine vibration signals from valve cover, cylinder head and cylinder …

Engine knock is a major cause of pollution, engine parts damage and metallic noise in an
engine. But somewhat knock in an engine can improve the power and economic …
