• Engine Compatibility: Primarily used in LADA and SAMARA series vehicles, including models 2108, 2109, 2115, 2113, 2114, 110 (2110), 111 (Kombi), and 112 (Schrägheck).
• Fuel Type: Designed for gasoline (petrol) injection.
• Operating Pressure: Optimized for high‑pressure fuel systems typical of modern inline‑four engines.
• Material Construction: Durable alloy housing with corrosion‑resistant coatings to withstand harsh engine environments.
• Seal Design: Precision O‑ring seals ensure leak‑free operation and maintain consistent fuel pressure.

Design Features & Performance Benefits

The injection valve incorporates several engineering advancements that contribute to its superior performance:

• High‑Precision Fuel Delivery: The injector’s needle and seat geometry are engineered for accurate metering, which translates into smoother throttle response and improved fuel economy.
• Rapid Response Time: Short dwell times allow the valve to open and close quickly, reducing lag and enhancing acceleration characteristics.
• Thermal Stability: The material selection ensures that the injector maintains its shape and sealing integrity even under high operating temperatures.
• Low Emission Compliance: By delivering fuel in a finely atomized spray, combustion is more complete, leading to lower hydrocarbon (HC) and carbon monoxide (CO) emissions.

Installation Guidelines

Proper installation of the Bosch 0280158502 Injection Valve is critical for achieving optimal engine performance. Follow these steps to ensure a reliable fit:

1. Preparation: Disconnect the battery and drain the fuel system to prevent accidental ignition.
2. Removal of Old Injector: Use a specialized injector removal tool to extract the existing valve without damaging the port or surrounding components.
3. Port Inspection: Clean the injection port thoroughly, removing any deposits or corrosion that could impede proper seating.
4. Injector Alignment: Align the new injector’s mounting flange with the engine block, ensuring that the needle seat matches the port geometry exactly.
5. Tightening Sequence: Tighten the injector in a cross‑pattern sequence to avoid uneven pressure distribution. Use a torque wrench set to the manufacturer’s specified value (typically around 15–20 Nm).
6. Sealing & Testing: Apply new O‑rings if necessary, then reassemble the fuel lines and perform a leak test before reconnecting the battery.

Maintenance Tips

While the injector is designed for longevity, routine checks can extend its life and maintain performance:

• Periodic Inspection: Every 20,000–30,000 miles (or as recommended by the vehicle manufacturer), inspect the injector for signs of wear or clogging.
• Fuel Quality: Use high‑quality gasoline with proper octane rating to prevent deposit buildup inside the injector.
• Cleaning Procedures: If deposits are detected, consider using a fuel system cleaner that targets injector residues.

Compatibility Summary

The Bosch 0280158502 Injection Valve is engineered to fit seamlessly into the following vehicle families and models:

• LADA series: 2108, 2109, 2115, 2113, 2114, 110 (2110), 111 (Kombi), 112 (Schrägheck)
