Bosch 0445116029 Injector

BOSCH 0445116029 Injector

The BOSCH 0445116029 injector is a high‑performance component designed for modern diesel engines that use the Common Rail system. It delivers precise fuel metering, ensuring optimal combustion, reduced emissions, and improved engine efficiency.

Key Technical Features

• Common Rail Compatibility: Engineered to work seamlessly with CRI‑318 high‑pressure rail systems.
• Piezoceramic Actuation: Utilises a piezoelectric element for rapid, accurate fuel injection timing.
• High‑Pressure Tolerance: Rated for pressures up to 2000 bar, matching the demands of modern turbocharged diesel engines.
• Durable Construction: Made from high‑strength alloys and ceramic components that resist wear and corrosion.
• Integrated Seal Ring: Features an internal sealing ring that prevents fuel leakage and maintains pressure integrity.

Vehicle Compatibility

The injector is specifically engineered for a wide range of Volkswagen Group vehicles, including:

• Audi A3 (8P1), A4 B8, A5, A6 C6, Q5, TT
• Seat Leon, Altea, Exeo, Toledo
• Skoda Octavia Mk2, Superb Mk2, Yeti
• Volkswagen Passat (various generations), Golf VI, Scirocco III, Tiguan 5N, Jetta, Eos, Golf Plus

All models listed above are equipped with the 2.0 L TDI or equivalent Common Rail diesel engines that require the 0445116029 injector for optimal performance.

Installation and Maintenance

1. Removal: Disconnect the high‑pressure fuel line, remove the old injector using a suitable extractor tool, and clean the mounting surface.
2. Inspection: Check for wear on the seal ring and ensure the injector body is free from cracks or damage.
3. Installation: Position the new injector into the cylinder head, torque to manufacturer specifications (typically 20–25 Nm), and reconnect the fuel line.
4. Testing: After installation, perform a pressure test to confirm correct operation before starting the engine.

Regular maintenance of the Common Rail system—such as periodic filter changes and injector cleaning—will extend the life of the 0445116029 injector and maintain peak performance.

Performance Benefits

• Enhanced Fuel Efficiency: Precise injection timing reduces fuel consumption by up to 5% compared with older injector designs.
• Lower Emissions: Optimised combustion lowers NOx and particulate matter, helping vehicles meet stringent Euro standards.
• Improved Power Output: Accurate fuel delivery supports the engine’s torque curve, delivering smoother acceleration.
• Reliability: The robust construction and integrated seal ring reduce the likelihood of injector failure or leakage.

Quality Assurance

The BOSCH 0445116029 injector undergoes rigorous testing at Bosch’s global manufacturing facilities. Each unit is inspected for dimensional accuracy, material integrity, and functional performance before shipping. This commitment to quality ensures that every injector meets the high standards expected by automotive manufacturers and end‑users alike.

Conclusion

Whether you are repairing a diesel engine or upgrading an existing system, the BOSCH 0445116029 injector offers reliable performance, precise fuel metering, and compatibility with a broad spectrum of Volkswagen Group vehicles. Its advanced piezoelectric technology, high‑pressure tolerance, and durable construction make it a top choice for engineers and mechanics seeking to maintain or enhance engine efficiency and longevity.
