Transient Electromagnetic Signals from Internal Combustion Engines

Abstract

A series of tests focusing on the frequency content and transient characteristics of the electromagnetic emissions from three different boat engines was performed at the Patuxent Naval Air Station. The transient emissions were compared with respect to engine rpm, amplification, orientation, shielding and against emissions from an engine of the same model. It was found that engine models can be identified according to their frequency content.
