Bosch Reliability: The 0 445 120 398 injector is part of Bosch's extensive lineup of fuel injection components, known for their quality and reliability.
It adheres to stringent manufacturing standards to ensure durability and performance.
Common Rail Technology: This injector employs common rail technology, a high-pressure fuel injection system that enables precise control of fuel delivery, resulting in improved fuel efficiency, reduced emissions, and enhanced engine performance.
High Pressure Operation: The injector operates at extremely high pressures, typically in the range of 1,800 to 2,200 bar (26,000 to 32,000 psi), ensuring efficient atomization of fuel and optimal combustion, which leads to reduced fuel consumption and emissions.
Piezo-Electric Actuation: Piezo-electric actuation technology is utilized in this injector. It relies on the piezoelectric effect, which allows for rapid and precise opening and closing of the injector's nozzle needle. This results in highly accurate fuel injection and improved engine efficiency.
Optimized Spray Pattern: The injector nozzle is designed to produce a fine and consistent spray pattern. This helps in achieving even fuel distribution within the combustion chamber, leading to cleaner and more efficient combustion.
Working Principles:
The Bosch 0 445 120 398 Common Rail Diesel Injector operates within the common rail system, which involves a high-pressure fuel rail that stores fuel at a constant pressure. Here's how it works:
Fuel Supply: Fuel is supplied to the common rail at high pressure by the fuel pump. This pressurized fuel is available for injection into the cylinders whenever needed.
Piezo-Electric Control: When the engine management system determines that it's time to inject fuel, it sends an electric signal to the injector. The piezo-electric actuator responds by rapidly opening the injector's nozzle needle.
Precise Fuel Injection: As the nozzle needle opens, pressurized fuel is injected into the combustion chamber.
The precise control provided by the piezo-electric actuation results in accurate timing and a consistent, finely atomized fuel spray.
Optimal Combustion: The fine fuel spray mixes with air in the combustion chamber, leading to efficient combustion. This process results in improved fuel economy and reduced emissions, as well as enhanced engine performance and reduced noise.
