摘要：

Self-ignition of hydrogen-air mixtures has been studied experimentally. This process was initiated behind a reflected shock wave at an initial pressure of up to 0.5 MPa and with hydrogen volume contents ranging from 9.5-20 and 40-60%. Simultaneous recording of pressure and temperature profiles near the end of a shock: tube made it possible to reveal the specific features of various self-ignition regimes and the regions of their existence. The peculiarities of the realization and evolution of mild and strong self-ignition processes are discussed, and a comparison with self-ignition of carbon-air mixtures is done.
