Cummins 3795257 HE211W Turbocharger Assembly

The Cummins 3795257 is a Holset HE211W wastegate turbocharger assembly designed for the Foton Cummins ISF2.8 liter diesel engine platform. This unit integrates a compressor wheel, turbine wheel, bearing housing, and integral wastegate actuator calibrated for the ISF2.8 power curve. It serves as a direct OEM replacement for Foton Auman and Aoling series light-to-medium duty trucks equipped with the ISF2.8 engine. The turbocharger utilizes a journal bearing system with oil-fed lubrication and water-cooled bearing housing for thermal management. The wastegate actuator is pneumatic, regulated by boost pressure reference. Critical clearances and rotor balance meet Cummins TC-01 specifications for durability under high exhaust gas temperatures.
