This invention discloses a liquid engine ignition device and method. The liquid engine ignition device includes a storage tank, an ignition tube, an exhaust check valve, and a shaped shuttle valve. The storage tank contains a storage tank piston, dividing the tank cavity into a storage chamber and a storage gas chamber. The ignition tube contains an ignition tube piston, dividing the ignition tube cavity into a tube body storage chamber and a compression gas chamber. The tube body storage chamber can hold the ignition propellant required for each ignition. The inlet of the tube body storage chamber is connected to the storage tank cavity, and the outlet is connected to the combustion chamber. During ignition, the shaped shuttle valve connects the compression gas source to the compression gas chamber, pushing the ignition tube piston to move and extruding the ignition propellant from the tube body storage chamber into the combustion chamber. In the non-ignition state, the compression gas chamber is connected to the storage tank cavity, pushing the storage tank piston to move and filling the tube body storage chamber with the ignition propellant from the storage tank cavity. This invention provides an engine ignition device that can automatically fill the ignition propellant and achieve multiple ignitions, and has a simple structure and good stability.
