throttle body fuel injection


throttle body fuel injection
A form of fuel injection in which the injectors are located at the engine's throttle body thereby feeding fuel to more than one cylinder. Such an arrangement saves money by using fewer injectors; but because it routes both fuel and air through the intake manifold it eliminates some of the tuning possibilities offered by port fuel injection. Also called single point injection
