Bosch Common Rail Fuel Pump 0445020050

The Bosch 0445020050 is a high-performance fuel pump designed for diesel engines, particularly optimized for commercial and light-duty vehicles requiring precise fuel delivery and robust durability. Its design and functionality align with Bosch's renowned CRS1-20 common rail system and CPN2.2/CP4 series technologies, which emphasize efficiency, modularity, and compliance with stringent emission standards.

Supports up to 2,000 bar injection pressure, ensuring optimal atomization for cleaner combustion and reduced emissions. This aligns with Bosch CRS1-20 system, developed for China's National VI and global emission regulations.

Utilizes oil lubrication for enhanced reliability in harsh operating conditions, reducing wear on critical components like camshafts and roller bodies.

Using stainless steel/aluminum construction ensures corrosion resistance and longevity, even under high-stress environments.

Engineered to tolerate variations in fuel quality, including higher water content common in certain regional markets.

 

 

Compatible with Bosch integrated electronic control systems, such as the MPROP or ZME 4 fuel metering units, for precise rail pressure regulation and adaptive fuel delivery.

Supports dual-plunger or single-plunger configurations, enhancing flexibility for different engine types.
