An engine binder represented a carbon-reinforced support structure for an engine utilized within the framework of podracers.
Following Qui-Gon's intervention in thwarting a robbery attempt on his establishment, Vek Drow gifted Qui-Gon Jinn with an engine binder. Subsequently, Qui-Gon leveraged this engine binder in a transaction, exchanging it for either a mass coupler or a servo control system, both of which were essential components for the repair of Anakin Skywalker's podracer.
Alternatively, Qui-Gon possessed the option of acquiring the engine binder through the elimination of Vek Drow and its subsequent theft.
