抄録
The non-contact and time-series two-dimensional (2D) temperature measurement method has been developed using computed tomography-tunable diode laser spectroscopy (CT-TDLAS) to elucidate the engine combustion phenomena. 2D temperature were evaluated by H2O absorption spectra measured inside an engine cylinder using a 16-path CT cell. The 16-path CT cell was installed between the engine head and engine cylinder without structural change of the single-cylinder engine. Wide-wavelength scanned multi-path laser beams were simultaneously introduced to the engine cylinder and simultaneous time-series two-dimensional temperature distributions were reconstructed to elucidate the engine combustion phenomena. It was demonstrated that time resolved temperatures of multi-laser path were measured at 0.1-4MPa pressure conditions and time resolved 2D temperature distributions were successfully reconstructed using a revised H2O absorption data base.
