Fuel Injector Assembly

Description

– A fuel injector assembly is a critical component of an internal combustion engine’s fuel system, responsible for delivering fuel into the combustion chamber.
– It precisely meters and atomizes fuel, ensuring it’s properly mixed with air for combustion.
– This process is vital for efficient engine operation, reduced emissions, and optimal performance.

Key Features:
Injector Nozzle:
The nozzle sprays the fuel into the combustion chamber, often with multiple outlets for better dispersion.
Needle Valve/Valve Body:
These components control the flow of fuel through the nozzle.
Actuator:
Modern injectors often use solenoids to precisely control the needle valve’s movement.
Control Chamber:
Some injectors have a control chamber where fuel pressure influences the needle valve’s position.
Fuel Passages:
Internal passages within the injector body direct fuel to the nozzle.
