The Bosch injector with part number 0445110659 is a common fuel injector used in various diesel engines, particularly in Volkswagen Group vehicles. Here are some important information about it:
0445110659 Key Specifications:
Type: Diesel solenoid fuel injector (piezoelectric or solenoid, depending on variant)
Application: Used in many VW/Audi 2.0 TDI and some 1.6 TDI engines (e.g., CR Common Rail systems).
Compatible Engines:
VW/Audi: Engines like the 2.0 TDI (CBEA, CFFA, CJAA) and 1.6 TDI (CAYC).
Other Vehicles: May also fit certain BMW, Mercedes, and Peugeot/Citroën diesel models.
Nozzle Type: High-precision multi-hole nozzle for efficient atomization.
Flow Rate: Varies by calibration, but typically around 200-250 cc/min (exact flow depends on engine tuning).
Pressure Rating: Designed for Common Rail systems with pressures up to 1800 bar or higher (depending on generation).
The Bosch 0445110659 fuel injector is a high-performance diesel injector designed for Common Rail Direct Injection (CRDi) systems. It offers several key characteristics and advantages that enhance engine efficiency, emissions control, and performance. Here’s a detailed breakdown:
1. Precision Fuel Delivery
Multi-Hole Nozzle Design: Features an optimized spray pattern (typically 6-8 holes) for superior fuel atomization, ensuring efficient combustion.
High Injection Pressure: Supports pressures up to 1,800 bar (or higher in newer versions), improving fuel efficiency and reducing particulate emissions.
Fast Response Time: Solenoid or piezoelectric actuation (depending on variant) allows ultra-fast opening/closing, enabling multiple injections per cycle (pilot, main, post-injection).
2. Enhanced Engine Performance & Efficiency
Optimized Combustion: Better fuel-air mixing leads to higher thermal efficiency, improving power output and fuel economy.
Reduced Emissions: Precise metering and multiple injections help lower NOx and soot emissions, complying with Euro 5/Euro 6 standards.
Adaptability: Works seamlessly with advanced engine management systems (e.g., VW’s EDC17 ECU) for dynamic adjustments.
3. Durability & Reliability
Robust Materials: Built with hardened steel and wear-resistant coatings to withstand high-pressure diesel environments.
Long Service Life: Engineered for 200,000+ km under normal conditions (with proper maintenance).
Leak-Resistant Design: Improved sealing (e.g., copper washers, upgraded O-rings) minimizes fuel leaks.
4. Compatibility & Integration
Wide Application: Used in VW/Audi 2.0TDI (CBEA/CJAA) and 1.6TDI (CAYC) engines, as well as some BMW and PSA Group diesels.
Plug-and-Play (with Coding): Direct replacement for older Bosch injectors (e.g., 0445110169), though ECU coding may be required.
5. Advanced Technology Features
Piezo/Solenoid Actuation:
Piezo Variant: Faster response (~5x quicker than solenoids), enabling finer control over injection timing.
Solenoid Variant: Simpler design, cost-effective, but slightly slower.
Closed-Loop Control: Works with engine sensors to self-adjust for optimal performance (e.g., compensating for wear over time).
6. Diagnostic & Service Advantages
Standardized Failure Codes: Common issues (e.g., imbalances, electrical faults) trigger specific OBD-II codes (P020X, P0263-P0266) for easier troubleshooting.
Refurbishment Potential: Nozzles and seals can often be replaced, extending injector life.
