Caterpillar Injector C9 New Brand New Fuel Injector C7 Diesel Engin293-4071 2934071 20R-1917 20R-8064 For Excavator 324D 325D 326D 329D Original New Injector

The c-aterpillar 20R-1917 fuel injector is a high-precision, OEM-compliant HEUI (Hydraulically Actuated Electronically Controlled Unit Injection) component specifically engineered for c-aterpillar C9 series diesel engines, strictly adhering to c-aterpillar’s original design standards, high-grade alloy material requirements and factory precision calibration parameters. As a reliable replacement option for C9 engine fuel injection systems, it is fully compatible with all standard configurations of c-aterpillar C9 diesel engines and can serve as an alternative to the related injector model 553-2592, with common part number variations including 20R1917 and CA20R1917. As a key component of the C9 engine’s HEUI fuel supply system, it integrates advanced hydraulic actuation mechanisms, high-sensitivity electronic control modules and precision-machined nozzles, enabling real-time and accurate regulation of injection timing, fuel delivery volume and injection pressure. This advanced design ensures ultra-uniform fuel atomization (with atomized particle diameter as fine as 15 microns), complete combustion, stable and powerful engine output, as well as excellent fuel economy, even under long-term high-load, high-temperature, high-vibration and dusty industrial operating conditions. With direct OEM plug-and-play compatibility, it requires no additional modific-ations or adjustments during installation, providing a convenient, efficient and cost-effective replacement solution for engine maintenance, overhaul and fault repair. Every component of this injector undergoes rigorous testing before shipping, including electrical performance, injection accuracy, high-low temperature resistance, pressure resistance, leakage and durability tests, ensuring consistent and reliable performance in various harsh working environments. Equipped with high-strength alloy steel internal parts, corrosion-resistant materials and enhanced sealing structures, the 20R-1917 injector effectively resists fuel leakage, carbon deposition, mechanical wear and high-temperature aging, significantly prolonging the service life of the C9 engine and reducing long-term operation and maintenance costs. It is widely applied to heavy-duty construction machinery, mining equipment, track-type tractors, motor graders and industrial generator sets equipped with c-aterpillar C9 series engines (especially c-aterpillar 330D, 336D and 340DL models), fully meeting the strict requirements of industrial and engineering operations for engine performance, reliability and emission standards. It also supports customized packaging and provides professional after-sales service, including online remote technical support and strict pre-shipment testing to ensure product quality.
