Observation of Automobile Ignition Coil Using X-Ray CT System

Introduction

Environmental concerns and carbon-dioxide reduction have come under focus with the global warming phenomenon, and features such as the start-stop system that prevents automobile engines from idling and reduces gas emissions at traffic lights are becoming more common. Because the start-stop system used in automobiles increases the number of times an engine is switched ON and OFF, it also increases the load on a variety of automobile components. One of these components is the ignition coil that creates an electric spark in the spark plug to ignite fuel when starting the engine and when the engine is running. Improvements must be made to the ignition coil to increase its durability and reliability. We present an example use of the inspeXio^TM SMXTM-225CT FPD microfocus X-ray CT system to observ the internals of an ignition coil.
