BOSCH Abschaltventil 0928400323

BOSCH Abschaltventil 0928400323

The BOSCH Abschaltventil 0928400323 is a precision-engineered component designed for the fuel injection system of modern automotive engines. It serves as an essential safety and control element, ensuring that the fuel supply can be interrupted instantly when required by the engine management unit.

Primary Functionality

This valve operates as a fuel cut‑off mechanism, allowing the engine controller to shut off the flow of gasoline or diesel into the injectors. By doing so, it prevents over‑fueling, reduces emissions during idle or shutdown conditions, and protects the injection system from damage caused by prolonged operation.

Key Technical Specifications

• Model Number: 0928400323
• Application: Fuel supply systems in gasoline and diesel engines, particularly those used in Mercedes-Benz Sprinter variants.
• Material Composition: High‑strength alloy with corrosion-resistant coating to withstand harsh fuel environments.
• Operating Pressure Range: Compatible with typical automotive fuel system pressures up to 200 bar.
• Electrical Interface: Designed for low-voltage control signals (12–24 V DC) from the engine control unit.
• Response Time: Sub‑millisecond actuation, ensuring rapid shutdown during transient events.

Installation and Compatibility

The valve is engineered to fit seamlessly into existing fuel lines without requiring extensive modifications. It features a standard 1/4” or 3/8” threaded connection that matches the majority of OEM fuel line fittings. The compact form factor allows it to be mounted in tight engine bay spaces, making it ideal for retrofit projects and factory installations alike.

Operational Benefits

• Enhanced Safety: Immediate interruption of fuel flow during fault conditions or emergency shutdowns.
• Emission Control: Reduces unburned hydrocarbons by preventing unnecessary fuel delivery when the engine is not operating.
• Engine Protection: Avoids injector wear and potential damage caused by continuous fuel exposure during idle periods.
• Reliability: Robust construction ensures long service life even under high-temperature, high-pressure conditions.

Maintenance Guidelines

Routine inspection of the valve’s mechanical and electrical contacts is recommended. Clean any debris from the inlet and outlet ports with a solvent compatible with fuel systems. Verify that the control signal remains within specified voltage ranges to ensure proper actuation.

Common Applications

• Mercedes-Benz Sprinter 3‑T Bus, 2‑T Van, and 3‑T Van models.
• Commercial delivery vehicles requiring stringent fuel shut‑off protocols.
• High-performance engines where precise fuel management is critical.
