Guide To Electronic Fuel Injection
The following guide mostly discusses multi-port electronic fuel injection systems due to the fact it is the dominate technique applied in most performance and racing applications. Earlier systems, relying on easier injectors, frequently injected into a sub-chamber shaped to swirl the compressed air and strengthen combustion this was recognized as indirect injection However, this was much less efficient than the now frequent direct injection in which initiation of combustion takes location in a depression (often toroidal ) in the crown of the piston.
Early injection systems utilized mechanical procedures to meter fuel, while almost all contemporary systems use electronic metering. Much better manage over the opening and closing of the injection nozzle to prevent uncontrolled secondary injections and present a sharp finish of injection. Single-point injection was utilised extensively on American-created passenger vehicles and light trucks for the duration of 1980-1995, and in some European automobiles in the early and …
