Abstract�� To investigate the ignition characteristics of nitrous oxide/propane, the torch igniter scheme of N2O/C3H8 was proposed initially. An igniter was designed and manufactured, and the experimental system was designed. The hot-tests under different condition of mass flow and excess-oxidizer coefficient show that the scheme is feasible, injector structure is reasonable, the spray quality and the excess-oxidizer coefficient are the key for successful ignition, and the igniter is able to generate multiple ignition and produce ignition torch successfully within the excess-oxidizer coefficient range 0.222~0.321. The experiment offers reference for the further study and establishes the foundation for achieving N2O/C3H8 motor ignition directly by this igniter.
