Fundamental Studies of Ignition Processes in Large Natural Gas Engines Using Laser Spark Ignition

Abstract

The current report details project progress made during the first quarterly reporting period of the DOE sponsored project "Fundamental studies of ignition processes in large natural gas engines using laser spark ignition". The goal of the overall research effort is to develop a laser ignition system for natural gas engines, with a particular focus on using fiber optic delivery methods. In this report we present our successful demonstration of spark formation using fiber delivery made possible though the use of novel coated hollow fibers. We present results of (high power) experimental characterizations of light propagation using hollow fibers using both a high power research grade laser as well as a more compact laser. Finally, we present initial designs of the system we are developing for future on-engine testing using the hollow fibers.
