The technology of internal combustion engines has improved to meeting international
regulations, applying turbocharging as an effective method. However, the works under
extreme conditions requires strict maintenance plans, since when it fails, it completely
deteriorates the functioning of the turbocharged engine. In this work, two procedures are
used to characterize some operating failures. Faulted blades are introduced in the
compressor to simulate typical failures observed in automotive turbochargers. Four …
