The working of a marine turbocharger depends on using exhaust gases from the engine to drive a turbine, which in turn drives a compressor that forces additional air into the engine.
This increased airflow allows the engine to burn more fuel, which produces more power. The turbocharger starts working when the engine reaches an optimal speed to produce enough exhaust to drive the turbine. Till then, a forced blower fan is used to supply air to the engine for combustion.
