XNZ1118900000 JP48A Turbocharger Assembly

This turbocharger assembly carries manufacturer part number XNZ1118900000 and model designation JP48A. It is engineered as a direct replacement for the original equipment turbocharger on Yuchai YC4E series inline four-cylinder, four-stroke, water-cooled, direct injection diesel engines. The YC4E series, derived from the YC6G platform, typically features displacements around 4.5 to 5.2 liters and power ratings from 105 kW to 147 kW, meeting Euro III emission standards. This unit applies to heavy duty truck platforms including the Sichuan Hyundai Jinqi series, which utilizes Hyundai Trago/Xcient cab configurations with 6x4 drive axles. The turbocharger utilizes a wastegate or variable geometry actuator mechanism typical for this engine displacement class, constructed with high-temperature alloy turbine housing and aluminum compressor wheel. Installation requires verification of oil feed and drain flange dimensions, coolant port alignment, and compressor outlet diameter against the specific engine sub-model (e.g., YC4E140-30, YC4E160-30). No OEM cross-reference numbers are published in the current dataset.
