III. Injector Technology & Characteristics

• Injector Technology: BOSCH CRIN 4.2 with "X-Pulse" pressure boosting for optimized fuel efficiency and performance.

• Nozzle Type: Precision multi-hole nozzle designed for maximum flow and enhanced atomization, contributing to improved combustion.

• Technical Characteristics:

  • Maximum Rail Pressure: 900 bar (up to 1160 bar for second generation systems)

  • Maximum Injection Pressure: 2500 bar (up to 2700 bar for next-gen engines)

  • System Modulation: The injector system adjusts the fuel injection pressure and timing dynamically based on engine operating conditions to optimize performance.

IV. Critical Technician Notes (MUST-DO)

• Specialized Tooling:
  Use BOSCH-specific tools for CRIN 4.2 system:

  • Wrench 30mm

  • Wrench 36mm

  • Nozzle Nut Wrench

  • Octagonal Nut Wrench

• Sealing Components:
  Replace all O-rings, washers, and sealing components using the designated CRIN 4.2 kit.

• Test Bench Verification:
  Ensure the injector meets performance standards by using the specific test bench adapter.

• Injection Pressure:
  The internal system of the injector adapts pressure to ensure optimal fuel delivery and combustion performance.

• System Identification:
  Mercedes-Benz refers to this system as "X-Pulse", which boosts fuel pressure for superior engine performance.

• Fuel Compatibility:
  Use clean, high-quality diesel (EN 590 Diesel or B7 Biodiesel blends). Regular fuel filter maintenance is crucial.

• Injector Coding:
  If necessary, use OEM diagnostic tools for injector coding to ensure proper integration with the vehicle's ECU.

• Post-Installation Testing:
  Perform a leak-back test or spray pattern verification using a test bench post-installation to ensure injector functionality.
