A new technique based on phosphor thermometry, for measurements of two-dimensional gas-phase temperature in combustion was established as a new laser diagnostic. The temperature calibration of Dy : YAG phosphor was taken at a surface of solid. The validation for applying gas-phase with line-intensity ratios method was evaluated with lifetime method and thermocouple data in a steady flow. These data showed the good agreements. Phosphor thermometry with single-shot was examined in turbulent combustion in an engine. The reasonable temperature deviation and the agreement with calculated data within 5% precision were achieved in the ignition process of compression ignition engine. The influence factors such as chemical luminescence and intrusion in combustion were discussed.
