Abstract

Laser-based techruques play an increasing role in diagnostics of combustion in the internal combustion engine because they give spatially and temporally resolved information on parameters such as temperature and species concentrations. One of the most widely used laser diagnostic techniques is coherent anti-Stokes Rarnan spectroscopy (CARS), of which different aspects have been reviewed in a number of paper (1),(5)In the present study, we adopted broadband CARS techmque to measure end-gas temperatures in a combustion chamber of a conventional 4-cylinder DOHC spark-ignition engine. A mobile CARS system measured a full CARS spectrum on shot by shot basis. The system consisted of a frequency doubled Nd:YAG laser(Continuum Surlite 11), broadband modeless dye laser and a monochromator equipped with a optical multi-channel analyzer(RG&G 1420).
