Wastegate Turbocharger Heat Exchanger
Cummins®

Wastegate A wastegate is a valve that controls the pressure of exhaust gas going to the turbocharger. It is typically located on the turbine housing and redirects excess exhaust gases away from the turbine wheel, regulating the speed of the turbocharger and preventing it from over-boosting. This helps to improve engine efficiency and reduce emissions. Turbocharger A turbocharger is a forced induction device that increases an engine's power output by compressing air before it enters into the cylinders. It consists of a compressor, which draws in air and compresses it, and a turbine, which is powered by exhaust gases flowing out of the engine. The compressed air is then forced into the cylinders at higher pressure than atmospheric pressure, resulting in more power. Heat Exchanger A heat exchanger is a component that transfers heat between two fluids without allowing them to mix together. In trucks, heat exchangers are commonly used for cooling purposes such as transmission oil or engine coolant. They work by passing one fluid through tubes or plates while another fluid flows around them on either side. This allows for efficient transfer of heat without contamination or mixing between fluids.
