![]() ![]() This system uses multiple ports on each cylinder’s intake valve to inject fuel into internal combustion engines. This system enables better engine performance and more exact control over the fuel mixture. 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. GM’s Vortec engines come with a Sequential Port Injection System (SCPI). Multiple fuel injectors are used in a multi-point fuel injection system, and they are positioned at the intake ports of each cylinder. One uses 'batch fire' injection, where groups of injectors pulse simultaneously a more precise method involves firing the injectors in a sequential order, to coincide with the intake valve opening in each cylinder. Sequential multi port injection free#Free Shipping.Loading Estimated Ship Date. The pulsing of the injectors in a multi-port system can be arranged using one of two methods.

Summit Racing carries Edelbrock Electronic Fuel Injection (EFI) Systems to give your engine better throttle response, more. ![]() 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. So, my cousin is in the market for a new fr-s and as so I started doing some research on them. There are three types of multi-point injection systems which include: Batched MPFI system Simultaneous MPFI system Sequential MPFI system. The throttle body unit also incorporated an idle air control valve (IAC) and a throttle position sensor (TPS). Single-point injection made economic sense because older carbureted intake manifolds could be used with light modifications. The atomized fuel then traveled through the intake manifold's runners to each cylinder's intake valves-just like a carburetor. 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.
