| Abstract: | In this paper the spectrum and correlation analysis of diosel engine
working process signal has been conducted using a computer program. Its applica-
tions to frequency analysis of cylinder pressure, intake and exhaust pressure; esti-
mation of combustion noise, intake and exhaust noise, frequency characteristics of
the indicator passage; examination of balance of working process and firing inter-
vals between cylinders; and condition monitoring are discu ssed. |
