This table details the core parameters of the 0445110565 injector, which determine its compatibility and performance. As a dedicated component for B-osch 110 series engines (also applicable to Jiangling 4JB1 engines, Foton C-ummins ISF3.8 engines, and Yuchai, Jianghuai, Quanchai, Weichai WP3.7 related engine models) and belonging to the CRI 1-16 category, it uses high-strength alloy steel to resist high pressure and corrosion, while the ceramic nozzle (matching nozzle model DLLA151P2379) ensures precise fuel atomization. The Euro 6 diesel adaptation and standard B-osch 110 working pressure (capable of withstanding high injection pressure as required by B-osch injector standards, with its pressure level higher than the basic CRI 2.0 and CRI 2.2 specifications which are 1450bar and 1600bar respectively) perfectly match the engine’s fuel supply needs, guaranteeing stable operation, reducing fuel consumption, and meeting strict environmental emission standards. Its precision manufacturing meets the micron-level dimensional requirements of B-osch common rail injectors, with key parameters such as armature lift (34~61 microns) and air gap (45~85 microns) complying with B-osch CRI series standards, ensuring reliable performance in long-term use. It adopts the standard structural design of B-osch CRIN injectors, consisting of five major components including electromagnet assembly, armature assembly, valve assembly, injector body and nozzle coupling, with precise matching gaps between components to ensure stable injection performance, which is consistent with the internal structural characteristics of mainstream CRI injectors. It is specifically adapted to Foton C-ummins ISF3.8 and Weichai WP3.7 diesel engines, perfectly matching the fuel system requirements of these engine models.

Operation Step Detailed Operation

Pre-Installation Preparation Disconnect the battery, check the injector for damage, clean the interface with professional cleaner, and confirm no debris in the installation hole.

Installation Operation Align the injector with the engine installation hole, fasten bolts evenly with 29-32 N·m torque (anti-clockwise for tightening) to avoid damage.

Pipe & Wire Connection Connect fuel pipes and electrical connectors, tighten joints with a wrench, apply sealant on gaskets to prevent fuel leakage and poor contact.

Post-Installation Test Reconnect the battery, start the engine, idle for 3-5 minutes, check for leakage, abnormal noise, and stable injection pressure.

Daily Operation Use clean diesel, avoid long-term idling, and check the injector’s electrical connection monthly to prevent nozzle clogging.

Proper usage directly affects the service life and performance of the 0445110565 injector. Pre-installation preparation ensures no damage to the product, while standard torque (anti-clockwise tightening) protects the injector and engine, which is in line with the standardized disassembly and assembly requirements of B-osch CRI series injectors that have strict precision requirements for assembly cleanliness and measurement accuracy, including key parameters such as armature lift and needle valve lift (420~850 microns for CRI 2.0 and CRI 2.2). Tight pipe/wire connection and post-installation test avoid fuel leakage and electrical failures. Daily attention to fuel quality and regular inspection can effectively prevent nozzle clogging, ensuring the injector maintains precise injection performance, which is crucial for its application in both B-osch 110 series and Jiangling 4JB1, Foton C-ummins ISF3.8, Weichai WP3.7, Yuchai, Jianghuai, Quanchai related engines and consistent with B-osch ’s quality management norms. Its working principle follows the hydraulic servo mode of B-osch CRIN injectors, and correct operation can avoid excessive wear of moving parts and ensure the stability of injection timing, which is consistent with the working principle of CRI series injectors. It is well-suited for Yuchai, Jianghuai, Quanchai, Weichai WP3.7 related engine models, ensuring stable and efficient fuel injection performance.
