description

0445110677 acts as the core common rail injection component for Yunnei KM 1.65L/1.9L/2.5L Euro 4 diesel engines. During daily delivery operations of light trucks, long-duration high-pressure fuel flushing, shifting load conditions and road vibration gradually create micro-wear on nozzle holes and fatigue damage to internal valve assemblies. This reduces injection precision, degrades combustion efficiency and causes continuous power drop. Optimized under SG04 light-duty commercial vehicle emission-compliant standards, this injector adopts high-stiffness wear-resistant alloy steel plus upgraded anti-fatigue valve set. Its precision-machined nozzle generates fine, evenly distributed fuel mist to support full combustion inside cylinders. The refined control valve optimizes injection timing and fuel metering accuracy, lowering risks of internal leakage and pressure loss. Reinforced internal structure withstands cyclic high-pressure impact. Every finished injector undergoes strict high-pressure cycle testing, atomization inspection and dimension calibration for direct swap of aged injectors.
