Specification

Description

The 456-3493 / 4563493 Fuel Injector is a high-precision common rail diesel injector developed for construction machinery engines, compatible with C9.3 series engines (such as the 336E excavator). As a core component of the engine fuel system, it atomizes fuel accurately under high pressure to achieve efficient combustion and ensure stable equipment operation. Manufactured with premium alloy materials to strict OEM design standards, the injector features excellent sealing performance and wear resistance. It serves as a direct replacement for the original part, offering easy installation and strong adaptability.

Advantage

OEM-Quality Assurance: Manufactured with high-precision processes and strictly screened key components, ensuring performance matches the original part perfectly with zero compatibility issues.
Efficient Atomization Technology: Optimized nozzle design enables more uniform fuel atomization, significantly improving combustion efficiency and reducing fuel consumption.
Enhanced Durability: Made of premium wear-resistant materials with precision sealing structures, the injector withstands high-pressure fuel impact, resists corrosion and aging, and extends service life.
Reliable Compatibility: Custom-developed for target engine models, compatible with various working conditions. No additional debugging is required after installation, allowing quick restoration of equipment performance.
Worry-Free After-Sales: Each injector undergoes rigorous performance testing before leaving the factory, backed by quality assurance to minimize equipment downtime and maintenance risks.

Performance

Precise Fuel Injection Control: Supported by the high-pressure common rail system, the injector maintains stable injection pressure with minimal errors in injection timing and quantity, ensuring smooth engine power output.
Efficient Combustion Performance: Optimized fuel atomization allows thorough mixing of fuel and air, resulting in more complete combustion, reduced emissions, and improved equipment power response.
Harsh Condition Adaptability: Designed to withstand high engine loads and temperatures, the injector operates stably in complex working conditions without common faults such as sticking or leakage.
Low Maintenance Cost: Excellent wear resistance reduces carbon deposit formation, minimizing the risk of injector clogging, extending maintenance intervals, and lowering equipment operating costs.
