Producer gas

The caloric value of the producer gas is low (mainly because of its high nitrogen content), and the technology is obsolete.

The term suction refers to the way the air was drawn into the gas generator by an internal combustion engine.

Air is passed over the red-hot carbonaceous fuel and carbon monoxide is produced.

During World War II in Britain, plants were built in the form of trailers for towing behind commercial vehicles, especially buses, to supply gas as a replacement for petrol (gasoline) fuel.

Modern 'natural gas' used in homes is far less toxic, and has a mercaptan added to it for odor for identifying leaks.
