advantage

• High-precision matched internal components. The injector body is forged from high strength alloy steel. Core needle valve, nozzle and control valve are carefully selected, processed to micron tolerance. It resists dripping, internal and external oil leakage under continuous high pressure, keeps injection action sensitive and stable, reduces stuck valve risks.
• Professional bench calibration & full inspection. Every injector is calibrated and tested on Bosch common rail bench. Test items cover idle flow, full load flow, pre-injection precision, opening pressure and return oil volume. Small injection deviation between individual injectors, excellent batch consistency, avoiding uneven fuel supply problems.
• Optimized 7-hole atomization structure. The 153° spray angle creates fine and uniform mist. Diesel mixes sufficiently with air inside cylinder. Combustion efficiency is greatly improved. It maintains stable power output under heavy intermittent load, cuts black smoke and reduces harmful exhaust emissions.
• Upgraded composite sealing design. Multiple sealing surfaces are optimized to prevent fuel seepage. It helps eliminate common faults like rough idle, slow flameout, carbon accumulation and engine shaking, extending service life of injector assembly.
• Direct replacement with good cost performance. Installation dimensions and interfaces follow original factory specifications. No pipeline modification required. It is an economical aftermarket spare part for engine overhaul and routine maintenance, helping customers cut maintenance expense.

FAQ

Q1: Can this injector fit all construction machinery engines?
A1: No. Model 0445120562 injector is dedicated for construction machinery diesel engine, matching OE number 1000946077. Construction machinery has many different engine series adopting different injector internal structure and spray parameters. Before ordering, please verify engine model and old injector OE code. Wrong part will lead to weak power, heavy black smoke, rough idle and even engine mechanical damage, and it may trigger emission fault codes.

Q2: What testing will be carried out before shipment?
A2: All injectors are 100% fully tested on professional common rail test bench before delivery. The test scope includes idle injection quantity, full-load injection quantity, pre-injection accuracy, injection opening pressure, return oil flow and static sealing leakage test. Products can only be packed after all indicators meet standards to minimize defective rate.

Q3: Is coding or calibration needed after installation?
A3: The injector is pre-calibrated on test bench before leaving factory and can be installed directly. If multiple injectors are replaced at the same time or fault codes exist in ECU, use professional diagnostic scanner to clear codes and perform injector IQA code writing and quantity compensation learning for smoother idle and better fuel economy.
