advantage

• 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 150° spray angle creates fine and uniform mist. Diesel mixes sufficiently with air inside cylinder. Combustion efficiency is greatly improved. It boosts power during heavy climbing, cuts black smoke and reduces harmful exhaust emissions.
• Strong adaptability for heavy-duty working conditions. Designed for Xichai 6DL2 heavy-duty engine, fit for J6 long-distance transportation, frequent start-stop and variable load. Stable performance under wide temperature range. Better tolerance to domestic low-grade diesel oil, lowering premature failure caused by impurity abrasion.
• 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 FAW Xichai engines?
A1: No. Model 0445120393 injector is dedicated for FAW Xichai 6DL2 engine, matching OE number 1112010-A630. Different Xichai engine series adopt 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.

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 quantity compensation learning for smoother idle and better fuel economy.

Q4: What preparation should be done before installation?
A4: Clean fuel lines thoroughly to remove metal debris and dirt. Replace fuel filter, injector copper washer and sealing ring. Check high-pressure fuel pump condition, because residual dirt and metal chips in oil circuit are the main reason for newly fitted injector early damage. Keep installation workspace clean to prevent dust entering high-pressure fuel circuit.
