BorgWarner 202V09100-7909 Turbocharger Assembly

This turbocharger assembly is manufactured by BorgWarner under the B3G model series, corresponding to the HE500WG frame size. It features an electronically controlled variable geometry turbine (VGT) mechanism designed for precise boost pressure management across the operating range of MAN D2066 and D2676 series engines licensed by Sinotruk. The unit integrates a water-cooled center housing rotating assembly (CHRA) with 360-degree thrust bearing lubrication. It is calibrated to match the specific compressor and turbine maps required for Euro IV/V/VII emission compliance on heavy-duty long-haul and construction applications. The actuator is a PWM-controlled electric stepper motor with integrated position sensor feedback. Mounting flange geometry and oil/coolant port orientations conform to Sinotruk OEM installation envelope for Howo T7H, Sitrak C7H, Hohan, and T5G chassis platforms.
