Our 0445120376 solenoid common rail injector strictly follows Bo-sch CRIN2 heavy-duty industrial manufacturing standards, exclusively engineered for Doosan DL06 six-cylinder diesel engines fitted on mid-size track excavators, wheel excavators and wheel loaders. It thoroughly eliminates typical construction site malfunctions including weak digging torque, unstable idle under heavy load, hard cold startup in low temperature, excessive fuel consumption and frequent DPF clogging triggered by worn original injectors. Plug-and-play installation without engine pipeline modification for machinery repair yards.
✅ Auxiliary Equipment: Small stone crushers, municipal engineering machinery
Unique Core Product Competitive Advantages
Site-Optimized Multi-Hole Nozzle For Intermittent Digging Cycles
Custom DLLA144P2446 multi-hole nozzle delivers balanced fuel atomization during frequent start-stop digging, grading and loading operations. Optimize low-speed torque output to cut down fuel waste for rental machinery with daily variable workload.
Dust-Proof Reinforced Sealing Structure Adapt To Construction Site Environment
Multi-layer high-temperature resistant sealing rings block cement dust, muddy water and sediment impurities in construction diesel, slow down carbon buildup inside injector core and extend service life under harsh on-site working conditions.
Full Industrial Bench Calibration For Construction Machinery ECU Logic
Each injector undergoes multi-point injection flow balance test, cold start response inspection and long-time leakage fatigue detection on dedicated DL06 test bench. Each unit attached with unique IQA calibration code to perfectly match Doosan original ECU control parameters.
Integrated OEM Matching Mounting Kit For Fast On-Site Maintenance
Identical thread size, sealing surface and electrical connector as factory original injector, brand-new high-temperature copper sealing washer included per unit, eliminate extra accessory purchasing and shorten machine downtime for construction fleets.
Two Cost-Effective Quality Grades For Different Equipment Usage Intensity
Brand-new injectors equipped with all brand-new nozzle, valve and sealing core parts for high-hour daily rental construction machines; remanufactured injectors replace all worn internal precision components and re-calibrated, ideal for private small-scale construction teams with limited maintenance budget.
