Condition Assessment of the Conical Surface of Atomizer Needles and Seats of Marine Diesel Engines by Acoustic Emission – Preliminary Research

Zygmunt RAUNMIAGI
Maritime University of Szczecin Chair of Machine Diagnostics and Repairs

The condition of the conical surface of the needle and seat in a fuel atomizer
can be assessed by using the acoustic emission method. The assessment of this
conical tribological pair can be performed by up-to-date measurement methods that
substantially enhance the quality of evaluating the technical condition of conical
surfaces of the atomizer needle and seat.
