1. Structural Characteristics
a) High-Precision Nozzle
Multi-hole nozzle design (typically 5-7 micro-holes) for fine fuel atomization.
Tapered seat valve ensures tight sealing to prevent leaks.
b) Solenoid Valve Actuation
Fast-response solenoid controls fuel delivery with high accuracy.
Integrated armature and needle valve for rapid opening/closing (response time in microseconds).
c) Robust Construction
Hardened steel body to withstand high rail pressures (up to 1,800+ bar in some systems).
Heat-resistant materials to endure extreme diesel engine temperatures.
d) Integrated Filter & Hydraulic Connections
Built-in micro-filter to protect against contaminants.
Precision-machined fuel inlet/outlet for optimal flow dynamics.
