Description

The Bosch injector with part number 0445110252 is a common rail diesel fuel injector used in various vehicle applications. However, without additional details about your specific engine model 8H, I can provide general information and possible applications for this injector.

Bosch Injector 0445110252 Details:

• Type: Common Rail Diesel Fuel Injector (Solenoid-controlled)

• Nozzle Type: Likely a high-precision Bosch nozzle for efficient fuel atomization.

• Applications: Used in multiple diesel engines, including some from Volvo, Renault, and possibly others.

• Compatible Vehicles:

• Volvo (certain D5 engines)

• Renault (some 2.2 dCi engines)

• Other European diesel engines (confirm with exact engine specs)

• 1. Main Components & Structural Features

• A. Solenoid Valve Assembly

• Electromagnetic solenoid- Controls injector opening/closing via ECU signals.

• Armature & needle valve- Moves to allow high-pressure fuel flow.

• High-tension electrical connector- Receives PWM (Pulse-Width Modulated) signals from the ECU.

• B. High-Pressure Fuel Delivery System

• Inlet fitting (common rail connection)- Seals to the rail (typical M12x1.5 thread).

• Fuel filter (internal)- Filters contaminants before fuel enters the nozzle.

• Pressure chamber- Maintains ultra-high pressure (up to 2,000+ bar in newer systems).

• C. Nozzle Assembly

• Micro-machined nozzle holes (e.g., 6–8 holes, ~0.12–0.18mm diameter) – Ensures precise fuel atomization.

• Needle guide & spring- Controls needle lift for injection timing.

• Tapered seat- Ensures tight sealing when closed to prevent leaks.

• D. Hydraulic Control System

• Control piston- Regulates nozzle needle movement hydraulically.

• Drain line connection- Returns excess fuel to the tank.
