The term « engine braking » refers to the braking effect that occurs in a petrol engine when the accelerator pedal is released. This causes the fuel injection to stop and the throttle valve to close almost completely, greatly limiting the forced airflow from, for example, the turbocharger.

Where are the brakes of the car?
