The pursuit of increased efficiency and reduced emissions in compressed natural gas (CNG) engines has led to the exploration of advanced ignition technologies. This study investigates the application of laser spark ignition (LSI) in lean burn CNG engines, aiming to improve combustion efficiency and engine performance. Laser spark ignition offers precise and controlled ignition by focusing a high-energy laser beam to initiate combustion, potentially overcoming the limitations of conventional spark plugs in lean burn conditions. The research evaluates the impact of LSI on key performance metrics including combustion stability, power output, fuel economy, and emission levels. Experimental results demonstrate that LSI enhances the lean burn capability of CNG engines, leading to significant improvements in efficiency and reductions in harmful emissions. The study also examines the practical challenges and benefits of integrating LSI technology into existing engine systems. Findings suggest that LSI represents a promising advancement for optimizing lean burn CNG engines, offering potential for broader application in sustainable automotive technologies.
