9/24/2023 0 Comments Sequential multi port injection![]() Two throttle body injection units were affixed to a modified intake manifold, each feeding the four cylinders on the opposing side of the engine-therefore, Cross-Fire. One of the few throttle body performance setups, Cross-Fire Injection, was produced by GM from '82 to '84 on some 5.0L and 5.7L V-8 Corvettes, Camaros, and Firebirds. Sequential Multiport Fuel Injector Assembly for 80.32. Fuel Injection System, Pro-Flo 4 XT, Self-Learning, Sequential Multi-Port, Black Powdercoated, 450 HP Max, Pre 1986 Small Block Chevy, Kit Part Number: EDL-35793 5. The throttle body unit also incorporated an idle air control valve (IAC) and a throttle position sensor (TPS). offers the great deal for genuine GM parts, 12592648. Single-point injection made economic sense because older carbureted intake manifolds could be used with light modifications. Though basic MPFI employs multiple injectors, they all spray their fuel at the same time or in groups. Although the MPFI has multiple injectors, they all spray their fuel at. Sequential fuel injection, also called sequential port fuel injection (SPFI) or timed injection, is a type of multiport injection. Sequential Fuel Injection, also known as the Sequential Port Fuel Injection (SPFI) or Timed Injection, is a type of Multi-Port Injection. The atomized fuel then traveled through the intake manifold's runners to each cylinder's intake valves-just like a carburetor. 3 (a) Single-point or Throttle Body (b) Port or Multi-Point (c) Direct Engine Fuel Injection System. Pro-Flo 4 EFI systems feature a high performance Edelbrock intake manifold with a 1,000 cfm throttle body, fuel rails and individual injectors for each cylinder. Single-point injection used a throttle body unit similar in base-structure to a carburetor, including a throttle plate(s) to control airflow, but with one or two extra-large fuel injectors mounted on top. The OEM’s only utilized throttle body style injection for 9 years before transitioning to sequential port fuel injection for improved drivability and efficiency. body injection, port fuel injection, sequential fuel injection and direct. In.At first glance, early mass-produced electronic fuel injected engines looked very much like they were carbureted.
