The following guide primarily discusses multi-port electronic fuel injection systems since it is the dominate system used in most performance and racing applications most of the theory and operation of multi-port systems is also applicable to throttle-body electronic fuel systems. Free essay: multi -point fuel injection [pic] contents chapters page no introduction 3 objectives 5 history and development 6 supersession of carburetor 10. Multi-point injection in a mpi system, each cylinder has its own individual injector the injectors are mounted at each of the intake ports so fuel can be sprayed directly into the ports. Multi-point fuel injection injects fuel into the intake ports just upstream of each cylinder's intake valve, rather than at a central point within an intake manifold.

Multi-port injection is the air/fuel delivery system used on most new cars it offers more accurate fuel delivery than throttle-body systems, though the basic idea is the same: a computer-controlled fuel delivery system that is programmable, emissions-compliant, and handles both high-performance and daily-driver applications. The multi-point electronic fuel injection (efi) system is an electronically controlled system which combines electronic sequential fuel injection and electronic spark advance systems. A sequential fuel injection is a type of multi-port fuel injection system in which each injection valve will open just before the cylinder intake valve opens so in essence, the individual injectors work by themselves because they are fired individually other multi-port systems will fire all the.
While turbochargers quickly reached what seems to be an evolutionary dead-end in motorcycles, today honda's programmed fuel injection (pgm-fi) technology has become prevalent for delivery of air/fuel mixture to the engine via high-pressure fuel injectors in a wide assortment of machines: street, dirt and atv. There is also the multi-point fuel injection system that injects fuel into the intake ports rather than at a central point within the engine manifold another example is the direct injection used by diesel engines where the injection nozzle is placed inside the combustion chamber. Working and the basic differences between the multi point fuel injection (mpfi) and common rail direct injection (crdi) engines are explained in this article.
