CFR Octane Rating Unit Engine and Dacia Single Cylinder SI Engine with Classical Spark Plug and Laser Ignition: Comparative Findings

1Abstract—Nowadays, research has developed new technologies for a better control of the combustion process. Among the new technologies used for Ignition and combustion control, the LASER Ignition system is defined as an innovative technology which could overcome several limitations of classical spark plug. The purpose of the paper is to present and disseminate the results of the experimental research on the LASER Ignition used in the Spark Ignition engine. Improved performance, ensuring rapid and robust combustion, depends on how the Ignition stage is achieved. It was designed, integrated and built so that it resembled a classical Spark Plug and could be mounted directly on the cylinder of a CFR Octane Rating Unit Engine, as well as on a Dacia Single Cylinder SI Engine, which led to several results among which: indicated, mediated pressures and their wave dispersion and also pollutant emission.
