The majority of current ICEs are no longer naturally aspirated, instead they employ boost systems to increase the air density. Usually, this is realizes via a turbomachine and particularly with a turbocharger, which exploits exhaust gas enthalpy to compress fresh air and to raise the engine volumetric efficiency. The objective is to suck as much air as possible decreasing engine displacements while keeping the same rated power. This practice is generally known as engine downsizing.
