Variable Geometry Turbocharger Actuator Service Kit
Cummins®

The 4034122RX Variable Geometry Turbocharger Actuator Service Kit, manufactured by Cummins, is designed to maintain and enhance the performance of variable geometry turbochargers (VGT) in heavy-duty truck engines. This Cummins part ensures the efficient operation of the turbocharger, which is vital for the overall performance and efficiency of the engine ¹.

Basic Concepts of Variable Geometry Turbocharger Actuator

Variable geometry turbochargers (VGT) differ from traditional turbochargers in that they allow for the adjustment of the turbine’s vanes. This adjustment is controlled by the actuator, which responds to signals from the engine’s electronic control unit (ECU). By altering the position of the vanes, the actuator can optimize the airflow through the turbine, which in turn affects the turbocharger’s speed and the engine’s performance. This dynamic adjustment is what sets VGTs apart from fixed geometry turbochargers, offering more precise control over engine performance under varying conditions ².
