Development and Evaluation of a Novel Optical Interface for Spark Ignition Engine Research 2002-01-0742

A key objective of this research was to develop an interface device to enable visualization of in-cylinder events within a production SI engine operating at normal speeds and loads, without the need for engine modifications. The device was designed to utilize the existing spark plug hole and to be capable of providing in-cylinder illumination, image transmission and a source of ignition. This technical paper presents the results of the initial evaluation of the device. The evaluation of the durability of the device, in terms of its ability to operate as a spark plug and its permissible operating range is presented. In addition, images of events in the cylinder captured using the device are provided.
