What controls the injectors on a TBI?

What controls the injectors on a TBI?

Then a computer, often referred to as the powertrain control module (PCM), activates the TBI injectors. The injectors spray fuel into the throttle body bore, right above the throttle plates. To control fuel pressure, the fuel pressure regulator routes excess fuel back to the fuel tank.

How many injectors does a TBI system use?

two injectors
Throttle Body Injection or TBI, uses one or two injectors mounted directly in the throttle body which spray fuel into the intake manifold.

Can you clean TBI fuel injectors?

Spray the injector or injectors with throttle body cleaner, and gently clean the exterior and the tip of the injector with the brush. Do not insert any metal objects into the tip of the injector, as this will enlarge the nozzle tip, permanently damaging the injector.

Do TBI systems use top fuel feeding injectors?

Throttle Body Injectors Or TBI, for short, they reside in a throttle body that is located where a carburetor used to be. Both side and top-feed injector types have been used in these applications.

What’s the difference between TBI and EFI?

just to clarify, TBI is EFI. efi stands for electronic fuel injection, which TBI most definantly is. most TBI trucks even had an EFI badge on the tailgate…. basically the difference between TBI and other injection methods comes down to placement and number/size of the injectors, as well as firing method/timing.

What is the difference between TBI and EFI?

Does the throttle body control the fuel pump?

Fuel pressure is created by an electric fuel pump (usually mounted in or near the fuel tank), and the pressure is controlled by a regulator mounted on the throttle body.

Can you change a TBI to a carb?

The most basic things you’ll need to convert from TBI to a carburetor is a carb and a matching manifold. You could try to track down a used stock manifold, but aftermarket aluminum manifolds like the Performer RPM make more power, are lighter and will only run you about $60.
