CR Injectors

Technical Specifications

1. Injector Components:
   • Injector Body: Houses all the internal components and is designed to withstand high pressures.
   • Nozzle: Features precision-drilled holes to atomize fuel into the combustion chamber.
   • Valve Assembly: Controls the timing and amount of fuel injection.
   • Control Solenoid: An electromagnetic device that precisely controls the injector needle based on signals from the engine control unit (ECU).
2. Dimensions and Tolerances:
   • Orifice Diameter: Nozzle orifice diameters typically range from 100 to 200 micrometers, with tolerances in the range of a few micrometers.
   • Critical Dimensions: Components such as the needle and valve require precise geometries to ensure proper sealing and fuel delivery.
3. Performance Requirements:
   • Pressure Handling: Injectors must withstand pressures up to 2,500 bar (36,000 psi) or higher.
   • Durability: Components must resist wear and fatigue under high-pressure cyclic loads.
   • Precision Fuel Delivery: The injector must provide precise fuel atomization and metering to ensure efficient combustion and compliance with emissions standards.

Quality Control and Testing

1. Non-Destructive Testing (NDT):
   • X-Ray Inspection: Used to detect internal flaws or inconsistencies in the material.
   • Magnetic Particle Inspection: Identifies surface and near-surface defects.
2. Dimensional Inspection:
   • Coordinate Measuring Machines (CMM): Used for high-precision measurement of injector components.
   • Surface Roughness Testing: Ensures the surface finish meets the required specifications for optimal performance.
3. Performance Testing:
   • Spray Pattern Analysis: Ensures the injector produces the correct spray pattern for optimal fuel-air mixing.
   • Flow Rate Testing: Verifies that the injector delivers the correct amount of fuel.
   • Durability Testing: Simulates long-term operation to ensure the injector can withstand prolonged use without failure.
