Key Features
Micron-Level Precision Machining: Ultra-fine grinding surface, ultra-small tolerance, perfectly fit the injector inner cavity, no jamming during high-frequency operation.
Strict Return Fuel Calibration: Effectively control injector return fuel volume, solve the problem of excessive return fuel and maintain stable rail pressure.
Excellent Wear & Corrosion Resistance: High-hardness alloy material resists long-term high-pressure impact and diesel erosion, extending injector service life.
1:1 OEM Interchangeability: Completely consistent with original installation size and working parameters, direct replacement for old valves, no modification needed.
High Cost Performance Repair: Replace only the control valve instead of the whole injector, greatly reduce construction machinery maintenance cost.
Solvable Common Faults
Injector excessive return fuel and internal pressure leakage
Difficult cold start, long cranking time and intermittent start failure
Unstable idle speed, engine shaking and misfiring
Insufficient engine power, weak acceleration and poor working performance
High fuel consumption and incomplete combustion caused by pressure instability
Injector working abnormality caused by worn or scratched control valve
