It means the engine sucks its air in by itself. On the other case on a force enducted engine the air is pressed in by a turbo compressor or a blower.

In reference to the gas tank I believe its referring to EFI as the tank must be pressurized.

Technically, a Blower and a Supercharger may be the same device but have different applications...A 'blower' is the term used by Detroit Diesel to describe the device that prevents vacuum starvation in their 2-stroke diesel engines. A DD with blower is still considered Naturally Aspirated by DD.
Traditionally, DD blowers have been used as superchargers on automotive spark engines.

Nit-picking over.
