Maintaining variable geometry turbochargers

The use of variable geometry turbochargers (VGT) is now standard on heavy- and medium-duty truck engines. Older wastegate actuator turbochargers were generally controlled by pressure or vacuum and operated basically as an on/off device. Today’s heavy- and medium-duty engines incorporate electronically controlled VGT. These new advanced turbochargers provide improved response across wider operating ranges (engine

From theory to reality: How soon will tomorrow’s trucks incorporate SuperTruck technologies?
