0 445 110 258 Fuel Injector Bosch Common Rail System, 0445110258
The 0 445 110 258 is a high-precision Common Rail Fuel Injector replacemnet for Bosch offered by RJT Parts. It isfor modern diesel engines. As a critical component of the fuel delivery system, it is responsible for atomizing fuel at extremely high pressures to ensure efficient combustion, better fuel economy, and reduced emissions.
Key Specifications & Features of 0445110258 Fuel Injector
This 0 445 110 258 fuel injector is built to withstand the rigorous demands of “Common Rail” technology, where fuel is kept at a constant high pressure in a shared manifold (the rail) before being injected.

Common Applications of 0 445 110 258 Fuel Injector
This specific 0445110258 fuel injector is most famously associated with Cummins and JMC (Jiangling Motors Corporation) engines. You will typically find it in:
JMC Baodian / Boarding pickups.
JMC Carrying light-duty trucks.
Transit vans (in specific regional markets).
Engine Models: Often paired with the 2.8L JX493 or similar Duratorq-derived diesel engines.
Why Precision Matters
In a Common Rail system, the injector doesn’t just “spray” fuel; it performs multiple injection events per combustion cycle (pilot, main, and post-injection).
Efficiency: The 0 445 110 258 uses a solenoid-controlled valve to manage fuel down to the microsecond.
Durability: Built with high-grade steel to resist the internal pressures which can exceed 1,600 bar (23,000+ psi).
Replacement Tip: Because these are precision instruments, they are highly sensitive to fuel contamination. Always replace the fuel filter when installing a new injector.
Note: When replacing this injector, it is often necessary to “code” the new injector’s calibration data into the vehicle’s ECU (Engine Control Unit) to ensure perfectly balanced performance across all cylinders.
