Product Introduction: DENSO Automotive Fuel Injector (Part Number: 295050-0920)
Executive Summary
The DENSO 295050-0920 fuel injector is a precision-engineered common-rail diesel injector designed for heavy-duty commercial and industrial applications. As a critical component of DENSO's advanced fuel injection systems, it ensures optimal combustion efficiency, reduced emissions, and reliable performance under extreme operating conditions. This document provides a detailed technical overview of its structural features, advantages, applications, OEM cross-references, and maintenance guidelines, serving as a comprehensive resource for engineers and technicians.
1. Structural Features and Technical Advantages
The DENSO 295050-0920 injector incorporates a precision multi-hole nozzle engineered to atomize fuel into a fine, uniform spray, optimizing air-fuel mixing and combustion efficiency. Its high-response solenoid valve enables rapid actuation, allowing multiple injection events per cycle (pilot, main, and post-injections) to minimize combustion noise and emissions. The injector's robust internal construction includes hardened components such as the armature, ball valve, and control piston, which withstand extreme pressures common in DENSO common-rail systems (e.g., applications for Hino J05E and J08E engines). A hydraulic servo mechanism leverages fuel pressure to ensure swift needle movement and tight sealing, while an optimized magnetic circuit reduces energy loss and heat generation, enhancing durability.
The technical advantages of the 295050-0920 include superior fuel economy and power output, achieved through high-pressure injection and milligram-level fuel metering accuracy. By promoting complete combustion, it significantly reduces particulate matter (PM) and nitrogen oxides (NOx), aiding compliance with modern emissions standards. The injector's exceptional durability stems from corrosion-resistant materials and minimized internal leakage, ensuring reliability in high-stress environments like construction machinery and long-haul trucks. Additionally, its adaptability allows seamless integration with advanced emission control systems, including exhaust gas recirculation (EGR) and diesel particulate filters (DPF).
2. Application Scenarios and Primary Application Fields
The DENSO 295050-0920 injector is primarily designed for heavy-duty diesel engines in commercial vehicles and industrial equipment. Key applications include:
- Heavy-Duty Trucks: It is compatible with Hino J05E and J08E engine series, ensuring reliable performance under high-mileage operations and extreme load conditions.
- Construction and Mining Machinery: The injector is used in excavators such as the Kobelco SK200-8 and SK300-8, where its resistance to vibration, contamination, and high-pressure fluctuations is critical.
- Industrial Engines: Suitable for stationary power generators and other machinery requiring consistent fuel delivery and emissions control.
To verify compatibility with specific engine models, consulting official DENSO documentation or OEM service manuals is strongly recommended.
3. OEM Cross-Reference Part Numbers
The DENSO 295050-0920 cross-references to multiple OEM and aftermarket part numbers, ensuring broad replacement compatibility. Key equivalents include:
- HINO OEM Numbers: 23670-E0540 and 23670-E0450.
- Alternative DENSO Codes: 295050-0240 (for Hino J08E engines).
- Aftermarket Options: Parts from suppliers like DJS (e.g., model 295050-0920) and others listed on global platforms.
For accurate identification, always prioritize the DENSO Original Part Number: 295050-0920 and verify cross-references through authorized DENSO catalogs or trusted automotive databases.
4. Recommendations for Daily Preventive Maintenance
To ensure longevity and optimal performance, implement the following maintenance practices:
- Use High-Quality Fuel: Always adhere to diesel standards (e.g., EN 590) to prevent nozzle deposits and internal wear. Contaminated fuel is a leading cause of injector clogging and failure.
- Regular Filter Replacement: Replace fuel filters every 15,000–30,000 km (or as specified) to avoid abrasive particle ingress, which can damage precision components under high pressure.
- Periodic System Cleaning: Employ certified fuel system cleaners to dissolve deposits. For severe fouling, professional ultrasonic cleaning is recommended.
- Electrical and Leak Checks: Monitor the injector's coil resistance (e.g., 0.5–0.7 mΩ for DENSO G2 models) and inspect for fuel leaks, cracked seals, or worn wiring during servicing.
- Professional Inspections: Schedule comprehensive checks every 60,000–100,000 km, including injector calibration and pressure testing with DENSO-approved tools.
- Nozzle and Needle Maintenance: Prevent needle valve sticking by disassembling and cleaning injectors periodically using non-abrasive tools (e.g., wooden sticks) to remove carbon deposits.
- Environmental Adaptations: In high-humidity or dusty environments, increase maintenance frequency by 30% and use protective measures like dust covers.
