Type: Common Rail Diesel Injector
Manufacturer: Bosch
Nozzle Type: Solenoid-controlled
Pressure Range: Typically operates at 1,600–2,000 bar (CRDi system)
The Bosch 0445110257 fuel injector (for the D4EA 2.0L CRDi engine) features several structural advantages that enhance performance, durability, and efficiency in common rail diesel systems:
1. Solenoid-Controlled Valve Design
Uses a high-precision solenoid for fast and accurate fuel metering.
Ensures quick response times (critical for modern high-pressure CRDi systems).
2. Multi-Hole Nozzle
Features an optimized spray pattern (typically 5–8 holes) for better fuel atomization.
Improves combustion efficiency and reduces emissions.
3. Robust High-Pressure Construction
Designed to withstand 1,600–2,000 bar rail pressure.
Reinforced body and hardened internal components resist wear.
4. Integrated Filter & Precision Machining
Includes a micro-filter to prevent clogging from contaminants.
Tight manufacturing tolerances ensure consistent fuel delivery.
5. Thermal & Pressure-Resistant Seals
Uses copper washers and high-temp seals to prevent leaks under extreme conditions.
6. Compact & Lightweight Design
Allows easy integration into tight engine spaces while maintaining durability.
