Bosch Reliability: The 0 445 120 002 injector is manufactured by Bosch, a renowned name in automotive components.
This injector is built with precision and adheres to the highest quality standards, ensuring reliability and longevity.
Common Rail Technology: This injector utilizes common rail technology, which is a high-pressure fuel injection system. It optimizes fuel delivery to the engine, resulting in improved power output and reduced emissions.
High-Pressure Operation: The injector is designed to operate at high pressures, typically exceeding 1,000 bar (14,500 psi). This high pressure is essential for atomizing fuel into fine droplets, promoting efficient combustion.
Precision Nozzles: The injector features precision-engineered nozzles that create a fine, consistent spray pattern. This ensures uniform fuel distribution in the combustion chamber, enhancing engine performance.
Piezo Actuation: The injector employs piezoelectric actuation technology. Piezo injectors are known for their quick response times, which enable precise control over fuel delivery and timing.
Improved Fuel Atomization: The injector's design enhances fuel atomization, breaking the diesel fuel into smaller droplets. This finer atomization results in more complete combustion, which contributes to increased engine efficiency and reduced emissions.
Enhanced Combustion Control: Through advanced electronic control systems, the injector can vary the injection timing and duration, optimizing combustion for different engine operating conditions. This flexibility improves power delivery and fuel economy.
Compatibility: The Bosch 0 445 120 002 injector is designed to fit a range of diesel engines, making it a versatile choice for various vehicle applications.
Working Principles:
The operation of the Bosch 0 445 120 002 Common Rail Diesel Injector is based on a few key principles:
High-Pressure Fuel Supply: The injector receives pressurized diesel fuel from a common rail. This rail is fed by a high-pressure fuel pump.
Piezo Actuation: When the engine control unit (ECU) sends a signal, the piezoelectric element within the injector expands or contracts rapidly, opening and closing the nozzle. This precise control allows for accurate fuel metering.
Injection Timing: The ECU determines the optimal injection timing based on engine parameters like load, speed, and temperature. This ensures that fuel is injected at the right moment for efficient combustion.
Fuel Atomization: As the injector nozzle opens, high-pressure fuel is forced through a tiny orifice, breaking it into a fine mist. This mist mixes with the compressed air in the combustion chamber for ignition.
