0445110376 | Bosch CRI2.2 Common Rail Injector – ISF2.8 Diesel Engine

The 0445110376 (0 445 110 376) is a Bosch CRI2.2 solenoid common rail injector engineered for ISF2.8 diesel platforms, delivering 88kW / 120HP output across light commercial, agricultural, and industrial applications. Each unit is calibrated to Bosch DCI700 bench standards, ensuring injection quantity and back-leakage parameters align with OE tolerances at 160MPa rail pressure. Built with a hardened control valve assembly and precision-matched DLLA145P2168 nozzle, this injector restores factory spray patterns and combustion efficiency in high-mileage diesel fleets. Whether you operate a repair workshop, run a parts distribution business, or maintain a mixed commercial fleet, the 0445110376 offers a reliable, cost-effective alternative to dealer-only replacements without compromising on calibration accuracy or durability.

This injector serves the ISF2.8 family deployed across Foton light trucks, GAZ Gazelle / Sobol commercial vehicles, and JAC platforms in global aftermarket channels. The CRI2.2 architecture is favored in regions where fuel quality fluctuates, as its solenoid actuation tolerates moderate contamination better than piezo equivalents. Industrial stationary engines, marine auxiliary units, and agricultural pump drives using the ISF2.8 base also accept this part number. Foton and GAZ listings vary by market calibration-always cross-check the OE label before ordering. Distributors serving Eastern Europe, the Middle East, and Southeast Asia should note that ISF2.8 variants appear in both Euro IV and Euro V configurations, and injector calibration codes may differ between emissions tiers. Stocking the correct 0445110376 batch ensures your customers receive a drop-in solution rather than a core return headache.

Proper priming is critical before initial start: the high-pressure rail must reach adequate volume, or extended cranking may occur without fire. Copper sealing washers should be replaced, and the injector bore cleaned to prevent combustion gas leakage. After installation, allow a five-minute idle to bleed residual air, then recheck balance rates after 50–100 miles of normal driving. Unlike some platforms, the ISF2.8 ECM typically self-relearns idle characteristics without mandatory programming-though verification via diagnostic scan is recommended for warranty traceability. Technicians should also inspect the fuel return line for restrictions, as a partially blocked return can mimic injector failure and lead to unnecessary replacement. Torque the injector clamp to ISF2.8 factory specification-typically 8–10 Nm-and never reuse stretch bolts where applicable. Keeping a DCI700 printout on file for each injector sold gives your workshop a baseline for future diagnostics and strengthens customer trust.

In a solenoid common rail injector, the control valve and nozzle assembly endure the harshest duty: pressures cycling at 160MPa with energizing times measured in microseconds. Vibration peening at the ball-seat contact surface creates a work-hardened sealing band that actually extends service life once bedding completes. However, contaminated fuel accelerates seat erosion and back-leakage drift, manifesting as rough idle, cold-start misfire, or drift compensation errors. For repair shops and distributors, stocking the 0445110376 alongside its 0445110594 replacement covers the majority of ISF2.8 service events, reducing vehicle downtime and return rates. A single injector failure often signals systemic fuel contamination-advising customers to flush the tank and replace the fuel filter at the same time protects your warranty and reduces comebacks. In price-sensitive markets, rebuilt units with documented DCI700 results offer a compelling middle ground between low-cost unknowns and expensive dealer stock.

Q1: Can I mix 0445110376 with 0445110594 in the same engine?
A: Yes, 0445110594 is the direct replacement assembly. Mixing is acceptable if quantity and calibration codes are matched per cylinder.

Q2: What causes return flow to exceed specification on these units?
A: Wear at the control valve seat or nozzle needle guide typically elevates back-leakage. Bench testing with a DCI700 confirms whether replacement or repair is required.

Q3: Do I need programming after installing this injector?
A: ISF2.8 platforms generally self-calibrate, but recording the new injector code ensures smoother adaptation and supports warranty claims.

Q4: What nozzle number is stamped on the genuine unit?
A: The service nozzle is DLLA145P2168 (0 433 172 168), a commonly counterfeited component-verify laser markings.

Q5: What warranty do distributors typically offer?
A: Quality aftermarket suppliers provide 12–24 months coverage, contingent on documented installation and fuel system cleanliness.

Q6: Is this injector compatible with biodiesel blends?
A: B5 and B20 are generally acceptable if fuel meets EN 590 or ASTM D975; higher blends may accelerate seal degradation and are not recommended.
