advantage

High-precision Original Matching Parts. The injector adopts high-precision imported internal components and high-strength alloy steel body. All core parts such as needle valve, nozzle and control valve are strictly screened, with micron-level machining tolerance control. It effectively avoids oil dripping, internal and external leakage under long-term high-pressure operation, ensuring sensitive and stable injection action.
Professional Bench Calibration & Full Inspection. Every finished injector is calibrated and tested on a professional Bosch common rail test bench. Multiple test items cover idle speed, full load, pre-injection, starting pressure and return oil flow. The injection consistency of single injectors and batch stability are excellent, with tiny fuel injection deviation.
Ultra-fine Atomization & Full Combustion. Optimized 7-hole spray structure and 153° spray angle enable uniform and delicate fuel atomization. The fuel mixes fully with air, which significantly improves combustion efficiency. It effectively boosts engine power, solves power attenuation during heavy-load climbing, reduces black smoke and harmful exhaust emissions.
Strong Working Condition Adaptability. Designed for Weichai WP10 heavy-load models, it adapts to complex working conditions such as long-distance transportation, frequent start-stop and variable load operation. It maintains stable performance in the temperature range of -20℃ to +120℃, and has excellent tolerance to medium and low-quality domestic diesel oil, reducing early failure rate.

FAQ

Q1: Is this injector suitable for all Weichai engines?

A1: No. This 0445120391 fuel injector is specially customized for Weichai WP10 diesel engine, matching OE number 612630090055. Different series of Weichai engines have different internal injector parameters and spray hole designs. Please confirm the engine model and original OE number before ordering. Mismatched injectors will cause insufficient power, heavy black smoke, jitter and even engine mechanical damage.

Q2: What testing items will be completed before shipment?

A2: All injectors pass 100% full-item testing on professional common rail test bench before delivery. The testing items include idle injection quantity, full-load injection quantity, pre-injection accuracy, injection starting pressure, return oil flow detection and static sealing leakage test. Only products with all indicators up to standard can be packaged and delivered to ensure zero defective goods.

Q3: What is the warranty policy and what damages are not covered?

A3: We provide 12-month warranty for products under correct installation and normal working conditions. The warranty does not cover damage caused by inferior dirty diesel, water mixed in fuel, long-term non-replacement of fuel filter, improper installation and torque error, private disassembly of parts, engine mechanical failure and man-made damage.
