ICCD Camera Enables PLIF Technique for Fuel Visualization in Engines

Large-bore, slow-speed, natural gas two-stoke cycle engines used for power generation and gas compression on natural gas pipelines suffer from poor in-cylinder mixing processes caused by ineffective fuel delivery, which can increase emissions and create low engine efficiency (higher fuel consumption). To address this problem, researchers at the Colorado State University (CSU) Engines and Energy Conversion Laboratory (EECL) used Planar Laser Induced Fluorescence (PLIF) to image the fuel in the cylinder, or combustion chamber.
