Product Introduction: DENSO Automotive Fuel Injector (Part Number: 095000-8011)
---
1. Structural Features and Technical Advantages
1.1 Structural Features
The DENSO 095000-8011 fuel injector is a high-precision component engineered for modern common-rail diesel systems. Its design incorporates several advanced structural features that ensure reliability and performance under demanding conditions.
- Precision Nozzle and Multi-Hole Design: The injector tip features a micro-machined nozzle with an optimized multi-hole pattern. This design ensures superior fuel atomization, creating a fine, uniform spray for optimal air-fuel mixing and combustion efficiency. The geometry of the holes is calibrated to maximize coverage in the combustion chamber while minimizing fuel wall impingement.
- High-Response Solenoid Valve: The injector utilizes an electromagnetic solenoid valve capable of rapid actuation, enabling multiple injection events per engine cycle (e.g., pilot, main, and post injections). This allows for precise control over fuel delivery, reducing combustion noise and emissions. The solenoid’s low inertia design ensures response times as fast as ±0.1 ms.
- Robust Internal Components: Critical parts, such as the armature, control piston, and ball valve, are manufactured from high-grade materials to withstand extreme pressures (up to 2,500 bar). The injector also includes an integrated filter to protect against contaminants, extending its service life.
- Hydraulic Servo System: A pressure-balanced hydraulic system amplifies the solenoid’s force to open and close the injector needle swiftly. This design ensures consistent performance across varying fuel pressures and temperatures.
- Optimized Magnetic Circuit: The solenoid coil and core are engineered to minimize magnetic reluctance, improving energy efficiency and reducing heat generation. This contributes to the injector’s long-term stability and fast response.
1.2 Technical Advantages
- Enhanced Fuel Economy and Power Output: The combination of high injection pressure and precise fuel metering improves combustion efficiency, leading to ~3% better fuel economy and higher torque output. The multi-hole nozzle reduces fuel droplet size, promoting complete combustion.
- Emission Reduction: By enabling cleaner combustion and multiple injections, the injector helps reduce NOx and particulate matter (PM) emissions by up to 50%, complying with Euro 6 and other stringent standards.
- Durability and Reliability: The use of hardened materials for the nozzle and valve seats ensures resistance to wear and corrosion. The injector’s design minimizes internal leakage, maintaining consistent performance over its lifespan.
- Adaptability: The injector is compatible with advanced emission control systems, such as 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 095000-8011 injector is designed for diesel engines in a wide range of vehicles and machinery. Its applications include:
- Passenger Cars and SUVs: Used in mid- to large-sized diesel vehicles to balance performance, fuel efficiency, and noise reduction. The injector’s ability to perform ultra-precise pilot injections minimizes diesel knock, enhancing driver comfort.
- Commercial Vehicles: Ideal for light-duty trucks, vans, and buses requiring high reliability under frequent stop-start cycles and long-distance operation. The injector’s robust construction ensures durability in high-mileage applications.
- Industrial and Agricultural Equipment: Employed in diesel-powered generators, tractors, and construction machinery (e.g., excavators). The injector’s resistance to vibration and contamination makes it suitable for harsh environments.
- Hybrid Powertrains: Integrated into diesel-electric hybrid systems to optimize fuel consumption and reduce emissions during urban driving.

3. OEM Cross-Reference Part Numbers
While specific OEM references for the 095000-8011 are not listed in the search results, DENSO injectors typically cross-reference to multiple OEM part numbers. For example:
- DENSO Original Number: 095000-8011 (base reference).
- Potential OEM Equivalents: Toyota (e.g., 23670-XXXXX), Bosch (e.g., 0 986 XYZ XXX), or other aftermarket codes (e.g., DCRI107580, INJD105N).
Recommendation: Always verify cross-references using official DENSO catalogs, OEM databases, or trusted automotive platforms to ensure compatibility. Incorrect part selection may lead to performance issues or engine damage.

4. Daily Preventive Maintenance Recommendations
Proper maintenance is critical to maximizing the injector’s lifespan and performance. Key recommendations include:
- Use High-Quality Fuel: Ensure diesel meets EN 590 or regional standards to prevent injector clogging and wear. Contaminated fuel is a primary cause of nozzle deposits and internal damage.
- Regular Fuel Filter Replacement: Change filters every 15,000–30,000 km (or as specified by the manufacturer) to avoid contaminant ingress. Clogged filters can lead to abrasive particles entering the injector, damaging precision components.
- Periodic Injector Cleaning: Use certified fuel system cleaners to dissolve deposits on the nozzle and internal parts. For severe fouling, professional ultrasonic cleaning is recommended.
- Electrical System Checks: Monitor the injector’s coil resistance (typically 0.5–3.0 Ω for DENSO models) during diagnostics. Abnormal readings may indicate electrical faults.
- Leak and Damage Inspection: Check for fuel leaks, cracked seals, or worn wiring during routine servicing. Address issues like rough idling or excessive smoke promptly to prevent further damage.
- Professional Servicing: Schedule comprehensive inspections every 60,000–100,000 km, including injector calibration, pressure testing, and seal replacement. Use DENSO-approved tools for accurate diagnostics.
