A __________ uses exhaust energy to increase the density of incoming air.

Explanation:
A turbocharger uses exhaust energy to increase the density of incoming air. The exhaust gases flow through a turbine, and as they spin it, the turbine drives a compressor on the intake side. This compressor squashes the incoming air, raising its density so more oxygen enters the combustion chamber. With denser air, you can burn more fuel and produce more power. This is different from a supercharger, which is belt-driven from the engine and doesn’t use exhaust energy; a ram air intake relies on vehicle speed to boost pressure rather than exhaust energy; and an electric turbocharger uses electricity to spin the compressor rather than exhaust gas.
