Weichai WPB1000418215 Turbocharger Assembly

The WPB1000418215 is a variable geometry turbocharger (VGT) designed for Weichai WP10 and WP12 series heavy-duty diesel engines meeting Euro IV/V/VI emission standards. The unit integrates an electronic actuator for precise boost pressure control across the operating range. The compressor wheel and turbine wheel are matched for high-altitude performance and transient response typical of city bus duty cycles. The center housing rotating assembly (CHRA) utilizes a full-floating bearing system with piston ring seals. The turbine housing features an integrated wastegate/vanes mechanism controlled by the electronic actuator. This assembly replaces OEM references BY1003714086, BY1003178647, and BY1004771612. Installation requires calibration of the actuator position sensor via diagnostic tool after mounting. Oil supply and drain ports conform to Weichai WP10/WP12 engine block interfaces. Inlet and outlet flanges match standard Weichai exhaust manifold and charge air cooler piping.
