Common Rail Fuel Injector Nozzle

Description

– A common rail fuel injector nozzle is a critical component in modern diesel engines, responsible for precisely delivering fuel into the combustion chamber.
– It plays a crucial role in optimizing engine performance by controlling fuel spray patterns, atomization, and injection timing, directly impacting fuel efficiency, emissions, and overall engine reliability.

Key Features:
High Pressure:
Common rail systems operate at very high fuel pressures (often over 2,000 bar), requiring robust and precise nozzles, according to Wikipedia.
Multiple Holes:
Nozzles have multiple precisely drilled holes to create the desired spray pattern and atomization.
Material:
Typically made from high-speed steel or other durable materials to withstand high pressure and temperature.
Electromagnetic or Piezoelectric Operation:
The nozzle’s needle valve is typically controlled by an electromagnetic or piezoelectric actuator, allowing for precise control of fuel injection events.
