Product Introduction: DENSO Automotive Fuel Injector (Part Number: 295050-0760)  

Executive Summary  

The DENSO 295050-0760 fuel injector is a precision-engineered component within DENSO's advanced common-rail diesel injection system portfolio. Designed to meet stringent global emissions standards and enhance engine performance, this injector exemplifies DENSO's commitment to innovation in fuel efficiency, durability, and emission reduction. While specific public technical data for the 295050-0760 model is limited, this document provides a comprehensive overview based on DENSO's established engineering principles, technical specifications from analogous injector series (e.g., G2, X1, X2), and industry standards for high-pressure common-rail systems. It covers structural features, technical advantages, application scenarios, OEM cross-referencing guidance, and preventive maintenance recommendations to serve as a reliable resource for engineers, technicians, and industry professionals.  

 1. Structural Features and Technical Advantages  

The DENSO 295050-0760 fuel injector incorporates cutting-edge structural features that ensure high performance under demanding conditions. Drawing from DENSO's G2 and X-series injector designs, it employs a precision multi-hole nozzle optimized for superior fuel atomization, enabling optimal air-fuel mixing and combustion efficiency. The injector's high-response solenoid valve achieves rapid actuation (with precision as tight as ±0.1 ms), allowing multiple injection events per cycle (e.g., pilot, main, and post injections) to reduce combustion noise and emissions . Its robust internal construction includes hardened components like the armature, ball valve, and control piston, which withstand extreme pressures (up to 1,800 bar in DENSO's common-rail systems) . A hydraulic servo system leverages fuel pressure to ensure swift needle movement and tight sealing, while an optimized magnetic circuit minimizes energy loss and heat generation . Critical internal adjustments, such as armature lift (typically 45–55 μm for G2 injectors), are finely calibrated to directly influence fuel delivery, particularly for pre-injection and full-load points . The technical advantages of the 295050-0760 are rooted in its structural design. It delivers enhanced fuel economy and power output through high-pressure injection (up to 1,800 bar) and milligram-level fuel metering accuracy, which promotes complete combustion . This also enables significant emission reduction, helping engines comply with modern environmental standards by optimizing fuel burn and minimizing particulate matter (PM) and nitrogen oxides (NOx) . The injector's durability and reliability are enhanced through hardened materials, minimized internal leakage, and resistance to wear/corrosion, even in high-stress environments . Additionally, its adaptability allows seamless integration with advanced emission control systems like exhaust gas recirculation (EGR) and diesel particulate filters (DPF), making it suitable for diverse engine configurations .  

 2. Application Scenarios and Primary Application Fields  

The DENSO 295050-0760 injector is designed for diesel engines in heavy-duty commercial vehicles and industrial machinery. Its primary application is in heavy-duty trucks, where it ensures reliable performance under high-mileage operations and extreme load conditions . The injector is also suited for industrial and construction equipment, including excavators and generators, where its resistance to vibration, contamination, and high-pressure fluctuations is critical . To confirm specific compatibility with engine models, consulting official DENSO application guides or vehicle service manuals is strongly recommended.  

 3. OEM Cross-Reference Part Numbers  

Cross-referencing part numbers is essential for identifying correct replacements. The primary identifier is the DENSO Original Part Number: 295050-0760. DENSO injectors typically cross-reference to multiple OEM part numbers; for example, analogous models like 295050-0810 correlate to Toyota OEM codes such as 23670-0L110 . Other potential equivalents include 295050-0920 (for Toyota 2KD-FTV engines) and 295050-1170 . For professional diagnostics, testing equipment may use templates labeled with DENSO injector numbering patterns. However, verifying cross-references via official DENSO catalogs, OEM databases, or trusted automotive platforms is crucial to avoid performance issues or engine damage .  

 4. Recommendations for Daily Preventive Maintenance  

Proper maintenance is critical for ensuring the longevity and optimal performance of the DENSO 295050-0760 injector. Key recommendations include using high-quality diesel fuel meeting regional standards to prevent nozzle deposits and internal wear . Regular fuel filter replacement every 15,000–30,000 km (or as specified) is essential to avoid contaminant ingress, as abrasive particles can damage precision components under high pressure . Periodic fuel system cleaning with certified detergents helps dissolve deposits, while professional ultrasonic cleaning is recommended for severe fouling . Electrical checks, such as verifying the injector's coil resistance (0.5–0.7 mΩ for G2 models), can identify faults early . During servicing, maintain extreme cleanliness to prevent contamination when opening the fuel system, and inspect for leaks, cracked seals, or worn wiring . Address symptoms like rough idling, power loss, or excessive smoke promptly to avoid further damage. For comprehensive care, schedule professional inspections every 60,000–100,000 km, including injector calibration and pressure testing using DENSO-approved tools . To prevent needle valve sticking, disassemble and clean injectors periodically with non-abrasive tools (e.g., wooden sticks) to remove carbon deposits from nozzle holes .
