0445110190 Injector Assembly for construction machinery

The 0445110190 common rail fuel injector is a mainstream high-precision core injection model of Bosch 110 series, widely equipped on Mercedes-Benz OM611/OM612 commercial diesel engine systems. In daily long-distance transportation, urban commuting and frequent high-load operation scenarios, the fuel injector endures long-term high-pressure fuel scouring, frequent injection opening/closing impact and variable load cycle operation, which easily causes nozzle wear, internal valve fatigue and injection precision attenuation, resulting in typical engine problems such as insufficient acceleration power, unstable idling, black smoke exhaust, poor cold start performance and increased fuel consumption. 0445110190 SG04 standard fuel injector assembly adopts exclusive SG04 commercial vehicle high-load targeted optimization. Core precision components adopt high-rigidity wear-resistant alloy steel matrix + anti-fatigue precision valve structure, balancing high-pressure injection stability and long-cycle wear resistance, fully adapting to high-frequency variable load operation of commercial diesel engines. The precision nozzle core undergoes SG04 standardized ultra-precision mirror grinding treatment, forming ultra-fine uniform fuel atomization particles, ensuring full combustion and effectively reducing exhaust emissions. The upgraded high-pressure control valve group optimizes injection timing and fuel metering accuracy, avoiding offset injection and oil leakage caused by long-term cyclic operation. The reinforced internal matching structure improves high-pressure impact resistance and structural stability, completely solving stubborn faults such as weak acceleration, jitter and excessive fuel consumption of old injectors.
