Description

 

The 370-7282 and 370-7280 common rail injectors are high-precision fuel supply components custom-developed for CAT construction machinery engines, specifically compatible with CAT 329F, E330GC excavators and their matched C4.4, C7.1 diesel engines. As the core of the engine’s electronic fuel injection system, these injectors are responsible for atomizing and injecting fuel into the combustion chamber with ultra-high pressure and precise timing, directly determining the engine’s combustion efficiency and working stability.
Manufactured in strict compliance with CAT’s OEM technical specifications, the injectors integrate advanced electronic control modules, high-pressure solenoid valves, and precision injection nozzles. Each unit undergoes rigorous calibration to match the fuel injection characteristics of C4.4/C7.1 engines, ensuring consistency with parameters such as injection pressure (up to 2000 bar), injection duration, and spray pattern. They are widely applied in heavy-duty construction scenarios such as earthmoving, road construction, and mining, adapting to harsh working environments with large load fluctuations, high dust levels, and frequent start-stop operations. The product undergoes 10+ rounds of quality inspections including pressure testing, leak testing, and dynamic performance testing to avoid common faults such as poor atomization, fuel leakage, and inconsistent injection, which could lead to reduced engine power and increased fuel consumption.

 

 

Advantage

  • Perfect Model Compatibility: Strictly following CAT’s 370-7282 and 370-7280 part number standards, these injectors achieve 100% fitment with CAT 329F, E330GC excavators and C4.4/C7.1 engines. The connector, installation size, and electronic communication protocol are fully consistent with the original parts, enabling plug-and-play installation without modifying the engine’s fuel system or ECU (Electronic Control Unit), significantly shortening maintenance time.
  • High-Precision Injection & Durable Core Components: The injectors adopt a wear-resistant ceramic valve seat and a high-response solenoid valve, which can complete injection actions in 0.1 milliseconds and control the fuel injection quantity error within ±1%. The high-pressure fuel passage is honed with a precision of 0.001mm, effectively resisting corrosion and wear caused by low-quality fuel. Compared with ordinary aftermarket injectors, their service life is extended by more than 40%.
  • Fuel Efficiency & Emission Reduction: The optimized spray hole design (multi-hole uniform distribution) and precise injection timing control make the fuel atomization more sufficient, the combustion more complete, and the fuel consumption of the engine reduced by 8-12% under the same working conditions. At the same time, it can effectively reduce the emission of nitrogen oxides (NOx) and particulate matter (PM), meeting the EU Stage IV and China National IV emission standards.
  • Strong Environmental Adaptability: The injector shell is treated with anti-corrosion and anti-dust coating, and the internal electronic components are equipped with a sealed protective structure, which can work stably in harsh environments with ambient temperature ranging from -40°C to 120°C, relative humidity up to 95%, and high dust concentration. It avoids injector failure caused by environmental factors and ensures the continuous operation of construction machinery.


Performance

  • Power Output Enhancement: By ensuring accurate and sufficient fuel injection, the injectors can increase the power of the C4.4 engine by 5-7% and the C7.1 engine by 6-9%, and the torque response speed is increased by 15%. When the CAT 329F/E330GC excavator is working under heavy load (such as breaking rocks and excavating hard soil), it can avoid power loss and improve construction efficiency.
  • Stable High-Pressure Performance: The injectors can maintain stable injection pressure under the working condition of 1600-2000 bar. Even after 5000 hours of continuous operation, the pressure fluctuation range is less than 3%, which effectively prevents the problems of uneven engine operation, jitter, and abnormal noise caused by unstable injection pressure.
  • Low Failure Rate & Long Service Life: Under standard maintenance and using qualified fuel, the average service life of the injectors reaches 12,000-15,000 hours for C4.4 engines and 10,000-13,000 hours for C7.1 engines. The annual failure rate is less than 2%, which is far lower than the industry average of 8%, greatly reducing the maintenance cost and downtime of construction machinery.
  • ECU Synergy & Fault Diagnosability: The injectors are fully compatible with the engine’s ECU system, which can realize real-time data interaction and adaptive adjustment. When a fault occurs, it can send fault codes to the ECU in time, which is convenient for maintenance personnel to quickly locate problems (such as blockage, leakage, etc.) through professional diagnostic equipment, reducing maintenance difficulty and time cost.
