What is multi-point EFI?

Fuel injection means

from the automobile engine it is generally injection passage, and an electronic control unit sensor group composed of three parts. If the injector is mounted on the intake pipe of each cylinder, i.e., gasoline is injected by a plurality of places (for each cylinder has at least one injection point) spray people cylinder, which is multi-point fuel injection.

1. The multi-point EFI noun

EFI means automobile engine is normally provided by injection passage, and an electronic control unit sensor group composed of three parts. If the injector is mounted on the intake pipe of each cylinder, i.e., gasoline is injected by a plurality of places (for each cylinder has at least one injection point) spray people cylinder, which is multi-point fuel injection.

2Features Multipoint EFI

Multi-point EFI cover mounted on each cylinder of an electromagnetic fuel injector directly injecting fuel into an intake manifold, then flowing through the air intake manifold flow mixing, when the intake valve is opened, the mixed gas is sucked into the cylinder. Multi-point EFI compared with the carburetor intake system, but also to solve the unevenness of adjacent cylinder intake valve overlap caused by power down, increasing fuel consumption problem fundamentally, and multi-point injection engines may be employed sequential injection, and thus air-fuel ratio control more accurate than a single point of injection, can be according to the timing of fuel injection, fuel injection quantity, injection timing precisely controlled, multi-point injection engine emissions better and more economical fuel.
