本文对用激光全息干涉技术测量内燃机燃烧室内温度场进行了研究。文中论述了激光全息干涉技术的基本原理,两次曝光法技术,测量光路的布置,实验装置的安排和实验步骤,反演计算等一系列技术问题,并提供了在模型燃烧室中温度场的测量结果,据此可以定量,精确地了解燃烧室内的温度分布。为实机测量和进一步研究燃油的蒸发,混合及燃烧规律打下良好的基础。 In this paper, laser holographic interferometry was used to measure the temperature field in the combustion chamber of an internal combustion engine. In this paper, a series of technical problems such as the basic principle of laser holographic interferometry technology, the double exposure method, the arrangement of measuring optical path, the arrangement of experimental equipment and experimental procedures, inversion calculation and so on are discussed. The temperature field in the model combustion chamber The results of the measurements give a quantitative and accurate picture of the temperature distribution in the combustion chamber. For the real machine measurement and further study of the evaporation, mixing and combustion rules laid a good foundation.
