Abstract
Abstract A device which is located between a carburetor and an engine intake manifold of an internal combustion engine includes oppositely rotating impellers mounted on air bearings. The air-fuel mixture exiting the carburetor impinges on the impellers and drives those impellers. Fuel droplets in the mixture are broken up to form a mixture capable of almost total burnout.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
247 words
A device for improving the fuel efficiency of an internal combustion engine comprising: a housing having a first bore defined therein located to be fluidly connected to an exit section of an internal combustion engine fuel intake means, a second bore defined in said housing and fluidly connected to said first bore; mounting means on said housing, said mounting means having a fluid passage defined therein; an air bearing on said mounting means; an air supply system fluidly connected to said air bearing; a first impeller mounted on said air bearing in said second bore, said first impeller having a multiplicity of blades oriented to be impacted by an air-fuel mixture flowing from the fuel intake means, said blades being pitched to drive said first impeller rotationally about said mounting means in a first direction as a result of force created by said impact between said first impeller blades and said fuel-air mixture; a second impeller mounted on said air bearing in said second bore, said second impeller having a multiplicity of blades oriented to be impacted by an air-fuel mixture flowing from said first impeller, said blades being pitched to drive said second impeller rotationally about said mounting means in a direction opposite to that of said first direction as a result of force created by said impact between said second impeller blades and said mixture; and air ingestion means on said mounting means for ingesting air from said air supply system into the air-fuel mixture.
Claim 2
Independent Claim
247 words
A device for improving the fuel efficiency of an internal combustion engine comprising: a housing having a first bore defined therein located to be fluidly connected to an exit section of an internal combustion engine fuel intake means, a second bore defined in said housing and fluidly connected to said first bore; mounting means on said housing, said mounting means having a fluid passage defined therein; an air bearing on said mounting means; an air supply system fluidly connected to said air bearing; a first impeller mounted on said air bearing in said second bore, said first impeller having a multiplicity of blades oriented to be impacted by an air-fuel mixture flowing from the fuel intake means, said blades being pitched to drive said first impeller rotationally about said mounting means in a first direction as a result of force created by said impact between said first impeller blades and said fuel-air mixture; a second impeller mounted on said air bearing in said second bore, said second impeller having a multiplicity of blades oriented to be impacted by an air-fuel mixture flowing from said first impeller, said blades being pitched to drive said second impeller rotationally about said mounting means in a direction opposite to that of said first direction as a result of force created by said impact between said second impeller blades and said mixture; and air ingestion means on said mounting means for ingesting air from said air supply system into the air-fuel mixture.
