BOSCH 0280156374 Injection Valve

The BOSCH 0280156374 Injection Valve is a precision‑engineered component designed for gasoline engines in a wide range of Volkswagen, Audi, UAZ and other automotive platforms. It delivers fuel with exact timing and pressure to ensure optimal combustion, power output, and emissions control.

Key Functional Characteristics

• Fuel Delivery Precision: The valve’s internal geometry is calibrated to atomize gasoline into a fine mist, promoting complete combustion and reducing unburned hydrocarbons.
• High‑Pressure Operation: Capable of operating at pressures up to 200 bar, it maintains consistent fuel flow even under high engine loads.
• Durability: Constructed from hardened steel with a corrosion‑resistant coating, the valve withstands prolonged exposure to fuel and combustion by‑products.
• Compact Design: Its small footprint allows seamless integration into existing engine bays without requiring major modifications.

Compatibility Overview

The injection valve is engineered for a broad spectrum of models, ensuring that it fits seamlessly into the following vehicle families:

• Volkswagen Golf II (19E, 1G1), Golf I Cabriolet (155)
• Audi 100 C4, Audi B4, Audi A6 Cabriolet
• Jetta II, Passat Variant (3A5, 35I)
• UAZ and other international platforms that use the same engine architecture.

Installation Highlights

Installing the BOSCH 0280156374 Injection Valve involves a straightforward process:

1. Disconnect the battery to prevent accidental ignition.
2. Remove the old injector by loosening the mounting bolts and carefully detaching the fuel line.
3. Align the new valve’s threaded end with the engine’s injection port, ensuring a snug fit.
4. Tighten the mounting bolts to the manufacturer’s specified torque.
5. Reconnect the fuel line, check for leaks, and re‑install any removed components.

Performance Benefits

• Improved Fuel Efficiency: Precise atomization reduces fuel consumption by up to 5% in optimal conditions.
• Enhanced Power Delivery: Consistent fuel pressure translates into smoother acceleration and higher peak horsepower.
• Lower Emissions: Complete combustion minimizes CO, HC, and NOx emissions, helping vehicles meet stringent environmental standards.
