According to one aspect, an apparatus and method for electrically igniting and throttling pyroelectric propellant, e.g., in a rocket engine, are provided. In one example, an apparatus includes an injector body for supplying an electrically ignitable propellant to a combustion chamber and a opposing electrodes. A first electrode may be included with the injector body and a second electrode positioned relative to the first electrode to cause ignition of the electrically ignitable propellant as the electrically ignitable propellant flows thereby.
