Throttle Body Injection
Throttle Body Injection (TBI) is a fuel injection system used in internal combustion engines where a single or dual fuel injector(s) are mounted in a throttle body assembly to spray fuel directly into the intake manifold. It was a transitional technology between carburetors and modern multi-port fuel injection, offering improved fuel metering and reliability over carburetors. TBI systems are controlled by an electronic control unit (ECU) that adjusts fuel delivery based on engine sensors.
Developers in automotive engineering, embedded systems, or IoT should learn about TBI when working on legacy vehicle systems, engine control unit (ECU) programming, or retrofitting projects. It's relevant for understanding fuel injection evolution, troubleshooting older vehicles (common in 1980s-1990s cars), and developing diagnostic tools or simulation software for automotive applications. Knowledge of TBI is also useful for hobbyists and professionals in automotive repair or restoration.
