Fuel saving devices are sold on the aftermarket with claims to improve the fuel economy and/or the exhaust emissions of a vehicle. There are numerous different types of device; many purport to optimize ignition, air flow, or fuel flow in some way. An early example of such a device sold with difficult-to-justify claims is the 200 mpg carburetor designed by Canadian inventor Charles Nelson Pogue.
