Embodiments of injectors configured for adaptively injecting and igniting various fuels in a combustion chamber are disclosed herein. An injector according to one embodiment includes an end portion configured to be positioned adjacent to a combustion chamber, and an ignition feature carried by the end portion and configured to generate an ignition event. The injector also includes a force generator assembly and a movable valve. The force generator assembly includes a first force generator separate from a second force generator. The first force generator creates a motive force to move the valve between the closed and open positions into the combustion chamber. The second force generator is electrically coupled to the ignition feature and provides voltage to the ignition feature to at least partially generate the ignition event.
