Not quite multi-port fuel injection, but not quite a carburetor, throttle-body injection was the interim gasoline-delivery technology that really came into its own during the 1980s. Thanks to the advent of affordable computer controls automakers could more precisely deliver air and fuel into engine cylinders, something that drastically improved efficiency and emissions.
Rather than having a dedicated injector for each cylinder throttle-body or central fuel injection placed a single delivery port at the throttle that served all cylinders. Think of it as half carburetor, half fuel injection. This technology was very cost effective and as a result extremely popular during the 1980s.
