This listing features a brand-new Common Rail Fuel Injector, specifically identified by the part number 28236381. Engineered for high-speed direct injection (CRDi) systems, this electro-hydraulic component serves as an exact replacement for the OEM reference 338004A700. It ensures precise micro-metering of diesel fuel, maintaining the specific factory rail pressure requirements essential for modern light commercial vehicles.
The 28236381 is calibrated exclusively for the 2.5-liter D4CB-A Diesel Engine, a turbocharged powertrain prominently utilized in the Hyundai H-1 (Grand Starex), Porter, and Kia Sorento chassis. This high-precision nozzle assembly utilizes advanced solenoid coil technology to deliver rapid multi-point injection sequences per combustion cycle. This exact volumetric delivery is critical for optimizing the thermal efficiency of the D4CB, maintaining its high payload torque while significantly suppressing off-boost exhaust particulate matter.
Worn injection units frequently result in harsh engine knocking, extended cold cranking, or premature DPF (Diesel Particulate Filter) overloading. Installing this genuine-spec Common Rail Fuel Injector eliminates internal return-leakage and restores the specific atomization pattern required by the Hyundai H-1 engine control unit (ECU). This direct-fit replacement guarantees reliable daily operation, optimal fuel economy, and strict emission compliance for your commercial fleet.
