Instrumentation of a Diesel Engine for Oil Film Thickness Measurements Using Fiber Optics and Laser Fluorescence.

Abstract

An apparatus was designed to measure the oil film thickness in a production diesel engine using the laser fluorescence technique. The apparatus incorporated fiber optic technology in its design in an attempt to improve on the ease of installation, portability, durability, and signal to noise ratio of previous designs using conventional optics. Bench tests and operational tests were conducted to evaluate the performance of the design. These tests indicate that the goals of the design were achieved, with a signal to noise ratio of the new design comparable to that of the conventional optics design.
