Variable Geometry Turbocharger Speed Sensor Kit
Cummins®

The Variable Geometry Turbocharger Speed Sensor Kit by Cummins is designed to enhance the performance and efficiency of heavy-duty trucks. This kit is integral to the operation of the engine, providing precise monitoring and adjustment of turbocharger speed to optimize engine performance ¹.

Basic Concepts

Turbochargers work by compressing the air entering the engine, which allows for more fuel to be burned and thus increases power output. Variable Geometry Turbochargers (VGT) take this a step further by adjusting the angle of the turbine vanes to control the flow of exhaust gases. This adjustment allows for more precise control over the turbocharger’s speed and, consequently, the engine’s performance. The speed sensor kit integrates with these systems by providing real-time data on turbocharger speed, enabling the engine control unit (ECU) to make necessary adjustments ².

Functionality of the Variable Geometry Turbocharger Speed Sensor Kit

This part operates by monitoring the rotational speed of the turbocharger. This data is crucial for the ECU to make informed decisions about fuel injection and air intake. By continuously providing accurate speed readings, the sensor kit allows the ECU to adjust the VGT vanes for optimal performance under varying driving conditions ³.
