Patent ID: 7717096

Claim:
An apparatus, comprising: a pre-combustion fuel mixing device, the device comprising: a housing; a first pre-combustion vortex chamber enclosed by the housing; a plurality of angled passages leading into the first pre-combustion vortex chamber for creating a vortex; a first oxidant fluid flow path in fluid communication with the first pre-combustion vortex chamber; a second pre-combustion vortex chamber enclosed by the housing, the second pre-combustion vortex chamber being larger than the first pre-combustion vortex chamber; a plurality of angled passages leading into the second pre-combustion vortex chamber for creating a vortex; a second oxidant fluid flow path in fluid communication with the second pre-combustion vortex chamber; a throttle body housing a valve, wherein the valve controls fluid flow through the second oxidant fluid flow path and is mechanically connected to a fuel pedal.
