• **Precise fuel injection control, perfectly adapted to heavy-duty engineering working conditions**
Delivers highly accurate injection quantity and timing under rapidly fluctuating loads. Sustains steady and reliable power output even under continuous heavy workloads on tough construction sites, effectively minimizing power sagging during sudden load changes and improving engine response.
• **High-efficiency atomization for optimized combustion and reduced fuel consumption**
Fine and uniform fuel spray greatly improves combustion efficiency. It effectively cuts black smoke emission and carbon deposition inside cylinders, saving fuel cost for equipment owners and lowering exhaust pollutant release to meet stricter emission requirements.
• **Premium wear-resistant core components, anti-impurity and less prone to valve sticking**
Core parts adopt high-strength alloy material processed by ultra-precision machining. It has strong resistance against abrasive particles mixed in diesel fuel, greatly extending the overall service life and reducing unexpected unplanned downtime of construction machinery.
• **Full bench testing for every unit, excellent performance consistency**
Each injector is fully tested for injection rate, sealing and leakage before delivery. Strict tolerance control ensures stable and consistent performance batch by batch, effectively reducing individual product performance differences for mass replacement.

FAQ 

Q1: What equipment and engines is the 2645A746 injector suitable for?
A1: It fits Perkins 1106D-E66TA engine, widely used for construction machinery. It is fully interchangeable with 320-0677,10R-7671 and other related injector models. Please confirm the engine model before installation to avoid mismatch, wrong model may lead to poor engine performance.

Q2: What failures can this injector solve?
A2: It can effectively repair common diesel engine faults: weak acceleration, unstable idle speed, difficult cold start, black/blue exhaust smoke, high fuel consumption and engine power drop. These symptoms are usually caused by aging or damage of original injectors.

Q3: Is coding and calibration required after installation?
A3: Factory pre-calibrated, plug and play without complicated coding. If replacing multiple injectors at the same time or ECU stores historical fault codes, clearing fault codes is recommended for better idle stability and fuel economy.

Q4: What is the product warranty and scope of exemption?
A4: 12-month professional warranty under standard installation and normal use. Damage caused by inferior fuel, water in oil, clogged fuel filter, wrong installation torque, unauthorized disassembly & modification or mechanical failure is not covered by warranty. Warranty is only valid following proper operation.
