Turbocharger Electric Actuator Kit
Cummins®

The Turbocharger Electric Actuator Kit (Part #4034211) by Cummins is designed to enhance the performance of turbochargers in commercial trucks. This part plays a role in the efficient operation of these vehicles by optimizing turbocharger performance, which in turn improves engine efficiency and overall truck performance.

Basic Concepts

To understand this Cummins part, it is important to grasp the fundamental concepts of turbochargers and electric actuators. A turbocharger compresses the air entering the engine, allowing more air to be mixed with fuel, which results in more powerful combustion and increased engine power ¹. An electric actuator controls the position of the turbocharger’s wastegate, which regulates the amount of exhaust gas bypassing the turbine. Together, these components work to enhance engine performance by ensuring the turbocharger operates within optimal parameters.

Purpose and Role
