These high-quality diesel common rail assemblies (Part Numbers: 0445214159, 0445226069) are core components of Bosch fuel injection systems, designed to deliver precise, high-pressure fuel supply for diesel engines, optimizing combustion efficiency, power output, and fuel economy while reducing exhaust emissions.
Engineered for direct OE replacement, they feature strict compatibility and reliable performance, with differentiated适配 for different diesel engine platforms:
0445214159 Common Rail Assembly: Exact fit for Cummins ISF2.8/ISF3.8 diesel engines, widely applied in light commercial vehicles such as Foton Aumark, JAC Refine, and pickup trucks. Designed with a maximum working pressure of 1800 bar, ensuring stable fuel injection even under high-load conditions. The integrated pressure relief valve prevents overpressure damage, protecting the entire fuel injection system.
0445226069 Common Rail Assembly: Specially compatible with Isuzu 4JK1/4JJ1 diesel engines, commonly used in Isuzu D-MAX, MU-X, and related commercial vehicle models. Adopts advanced multi-hole injection technology, with a precision-machined inner rail to ensure uniform fuel distribution to each injector. The corrosion-resistant stainless steel rail body adapts to harsh working environments such as high temperature and humidity.
Shared Core Advantages of Both Assemblies:
Premium Material & Craftsmanship: High-strength stainless steel rail body with CNC precision machining; strict leak-proof testing ensures no fuel seepage.
OE-Level Performance: 100% matched with original engine parameters, directly restoring engine power and fuel efficiency, reducing black smoke and noise.
Stable & Durable: Equipped with high-precision pressure sensors and solenoid valves; undergoes 100% dynamic performance testing, with a service life of ≥300,000 km.
Easy Installation: Direct bolt-on design, consistent with original mounting points and connectors; no modification required, saving repair time.
Quality Assurance: Complies with ISO/TS16949 and Bosch technical standards; 12-month warranty against manufacturing defects.
