In this project selected fuels and fuel blends are characterized regarding their auto-ignition behavior at elevated pressures. The chemical ignition delay times of homogeneous, gaseous combustion mixtures is determined in a high-pressure shock tube, whereas physico-chemical ignition delay times after liquid injection are measured in a high-temperature-high-pressure combustion chamber. Through a combination of experimental investigations and 0D and 1D numerical simulations relevant time scales are optimized, in order to support the realization of the quasi-homogeneous auto-ignition in shockless explosion combustor (SEC).

在这个项目中，选定的燃料和燃料混合物的特点是关于他们的自燃行为在高压。均质气体燃烧混合物的化学点火延迟时间是在高压激波管中确定的，而液体喷射后的物理化学点火延迟时间是在高温高压燃烧室中测量的。通过实验研究和一维、一维数值模拟相结合的方法，优化了相应的时间尺度，为无激波爆炸燃烧室（SEC）实现准均质自燃提供了理论依据。
