Komatsu Excavator Parts fuel injector 6745-11-3102

The fuel injector in an excavator is a critical component of its engine's fuel system. It plays a key role in delivering precisely measured amounts of fuel into the engine's combustion chambers at the right moment for efficient combustion. Here's an overview of the fuel injector and its function:

Function of Fuel Injector:

1. Fuel Delivery: The primary function of the fuel injector is to spray atomized fuel directly into the combustion chamber of the engine in a finely misted form. This ensures proper mixing of fuel with air for efficient combustion.

2. Precision: Fuel injectors deliver fuel in highly controlled and precise quantities, timed to coincide with the engine's intake stroke. This precision helps optimize engine performance, fuel efficiency, and emissions.

3. Atomization: The fuel injector breaks down the fuel into tiny droplets, maximizing surface area and promoting thorough mixing with air, which enhances combustion efficiency and reduces emissions.

Components of Fuel Injector:

1. Nozzle: The nozzle is the component through which the fuel is sprayed into the combustion chamber. It features precision-engineered orifices to regulate fuel flow and atomization.

2. Injector Body: The injector body houses the internal components of the fuel injector, including the nozzle, solenoid or piezoelectric actuator (depending on the injector type), and internal passages for fuel flow.

3. Solenoid or Piezoelectric Actuator: Fuel injectors may use either a solenoid or piezoelectric actuator to control the opening and closing of the injector nozzle. Solenoid-based injectors are more common in traditional diesel engines, while piezoelectric injectors are found in some modern high-performance diesel engines.
