Turbocharger Kit
Cummins®

The 5456746RX Turbocharger Kit, manufactured by Cummins, is designed for use in commercial trucks. This kit is part of a broader category of turbocharger systems that enhance engine performance. Turbocharger kits, in general, play a role in increasing the efficiency and power output of internal combustion engines by forcing additional air into the combustion chamber ¹.

Basic Concepts of Turbocharger Kits

Turbocharger technology involves using exhaust gases to spin a turbine, which in turn drives a compressor. This compressor increases the mass of air entering the engine, allowing for more fuel to be burned and thus generating more power. A turbocharger kit typically includes the turbocharger itself, along with necessary mounting hardware, hoses, and sometimes an intercooler to cool the compressed air before it enters the engine. Each component in the kit contributes to the overall function of boosting engine performance ².
