TRB meaning in Airport Code ?

A turbocharger (technically a turbosupercharger), colloquially known as turbo, is a turbine-driven, forced induction device that increases an internal combustion engine's power output by forcing extra compressed air into the combustion chamber.This improvement over a naturally aspirated engine's power output is because the compressor can force more air—and proportionately more fuel—into the combustion chamber than atmospheric pressure (and for that matter, ram air intakes) alone.

Manufacturers commonly use turbochargers in trucks, cars, trains, aircrafts, and construction-equipment engines. They are most often used with Otto cycle and diesel cycle internal combustion engines.
