Type of Work
Paper, Research Project
Mechanics have always used sounds to "trouble shoot" an engine. To a trained ear, each sound is different. Since an ear can be this sensitive, this paper will attempt to prove that electronic equipment can be considerably more accurate in detecting engine problems. The writer of this paper has attempted a project in which he hopes to prove that valve and bearing problems can be located by studying oscilloscope displays. These displays would picture the sound frequencies of valve and bearings in operation. The writer assumed that a comparison could be made of the displays of a normal engine operation and an abnormal engine operation, and an observation of any variance in the frequencies or wave forms could be identified.
