Plasma Injector

A Plasma Injector is a component of a starship's warp drive system, the EPS, which propels drive plasma into the Warp Coils. (DS9: "Captive Pursuit")

The Enterprise NX-01 operated five plasma injectors. When the fifth one started to fail in 2152, the Enterprise acquired one replacement and two spares from the Kreetassans after a lengthy negotiation process, although the ship could have continued normal operation with only four working injectors.
