Throttle Body Injection System

The heart of the Powerjection I fuel-injection system is the throttle-body which is available in die-cast or billet aluminum with either a natural or polished finish. The injectors spray fuel into the top of the throttle body air horn The TBI fuel spray mixes with the air flowing through the air horn. It consists of a housing unit that contains a throttle plate butterfly valve that rotates on a shaft. Throttle body injection is a type of fuel injection system that served as a segue between carburation and multiport fuel injection. Multi-point injection port injection and single-point injection throttle-body injection. The throttle body injection TBI system uses one or two injector valves mounted in a throttle body assembly. A typical TBI assembly has a fuel metering body that sits on top of the throttle body.

In simple terms we have either throttle body injection TBI where the injectors are mounted in the throttle body assembly providing a central point airfuel delivery atop the intake manifold or multipoint fuel injection MPFI where one fuel injector is dedicated per cylinder with each injector providing fuel closer to each combustion chamber at the output end of each intake.

A typical TBI assembly has a fuel metering body that sits on top of the throttle body. These systems have a fuel injector for each cylinder usually located so that they spray right at the intake valve. The throttle body is a tube containing a pivoting flat valve butterfly that is used to control the amount of air entering an engine. The heart of the Powerjection I fuel-injection system is the throttle-body which is available in die-cast or billet aluminum with either a natural or polished finish. Its the most universal type of Electronic Fuel Injection system but its not ideal for high performance engines. Throttle body injection TBI system Working of electronic fuel injection system.

What Does Injection Style Mean

Throttle body injection system. Choose from standard or with GM 4L6080E transmission control. The throttle-body bolts directly onto any 4150 Holley open-chamber manifold and is identical in dimensions to a 4150 carburetor allowing users to retain their original linkage air cleaner and fuel line. Its a single compact unit that mounts atop the intake manifold in pretty much the same way as a carburetor hence the appeal to automakers.

It consists of a housing unit that contains a throttle plate butterfly valve that rotates on a shaft. What Is A Throttle Body Injection SystemWatch more videos for more knowledgeHow Does A Throttle Body Fuel Injection Work. The throttle body injection TBI system fig.

This design delivers the fuel into the air flow stream in the plenum similar to a carburetor. 4-46 uses one or two injector valves mounted in a throttle body assembly. The throttle bodies in these systems are similar to those used in other more modern fuel injection systems aside from the fact that they have built-in fuel injectors.

Installing a throttle body injection EFI system is not too much more difficult than installing a carburetor. The heart of the Powerjection I fuel-injection system is the throttle-body which is available in die-cast or billet aluminum with either a natural or polished finish. Gradually as new engines were designed throttle body fuel injection was replaced by multi-port fuel injection also known as port multi-point or sequential fuel injection.

Its the most universal type of Electronic Fuel Injection system but its not ideal for high performance engines. Throttle Body style EFI systems feature fuel rails and injectors mounted directly to a throttle body. A typical TBI assembly has a fuel metering body that sits on top of the throttle body.

Throttle-body injection definition a fuel-injection system in which an injector throttle-body injector delivers fuel to a central location within the intake manifold of. These systems have a fuel injector for each cylinder usually located so that they spray right at the intake valve. The EZ-EFI system is a self-tuning injection system that can support up to 550hp and is supplied complete with the ECU oxygen sensor wiring harness and optional fuel pump.

These systems provide more accurate fuel metering and quicker response. The throttle body injection TBI system uses one or two injector valves mounted in a throttle body assembly.
