Method and apparatus for supplying fuel-air mixtures to internal combustion engines

Claim 1

APPARATUS FOR SUPPLYING FUEL-AIR MIXTURES TO THE CYLINDERS OF AN INTERNAL COMBUSTION ENGINE COMPRISING AN AIR INTAKE CHANNEL, A FUEL NOZZLE OPENING INTO THE CHANNEL, A THROTTLE VALVE IN THE CHANNEL DOWNSTREAM OF THE FUEL NOZZLE, A TURBULENCE CHAMBER POSITIONED IMMEDIATELY DOWNSTREAM OF THE THROTTLE VALVE INTO WHICH THE FUEL-AIR MIXTURES FLOW FROM THE CHANNEL, SAID TURBULENCE CHAMBER PROVIDING AN ABRUPT INCREASE IN CROSS-SECTIONAL AREA FOR THE FUEL-AIR FLOW, SAID TURBULENCE CHAMBER HAVING A DIAMETER WHICH IS AT LEAST TWICE THE DIAMETER OF THE INTAKE CHANNEL AND A LENGTH IN THE DIRECTION OF FLOW OF THE FUEL AIR MIXTURES WHICH IS AT LEAST FOUR TIMES THE DIAMETER OF THE INTAKE CHANNELS, SAID TURBULENCE CHAMBER HAVING AT LEAST ONE OUTLET FOR THE FLOW OF THE FUEL-AIR MIXTURES TO THE ENGINE CYLINDERS, AND MEANS ACTUATED BY THE DIFFERENCE IN PRESSURE BETWEEN ATMOSPHERIC PRESSURE AND PRESSURE IN THE TURBULENCE CHAMBER FOR APPROXIMATELY MAINTAINING AT FULL POWER OPERATION AT ALL ENGINE SPEEDS A PREDETERMINED PRESSURE DROP BETWEEN ATMOSPHERIC PRESSURE AND THE PRESSURE IN THE ENTRANCE PORTION OF THE TURBULENCE CHAMBER.

Claim 3

A METHOD OF SUPPLYING A FUEL AIR MIXTURE TO CYLINDERS OF AN INTERNAL COMBUSTION ENGINE WHICH COMPRISES FLOWING THROUGH A CHANNEL AIR CONTAINING COARSE FUEL DROPLETS PAST A VARIABLE CONSTRICTION IN THE CHANNEL TO FORM HIGH VELOCITY JETS OF AIR CONTAINING FUEL DROPLETS, INJECTING SAID JETS IMMEDIATELY INTO THE CENTRAL PORTION OF A TURBULENCE CHAMBER HAVING A LARGER CROSS SECTION THAN SAID CHANNEL TO PREVENT SAID JETS IMPINGING ON THE WALLS OF SAID CHAMBER AND TO CONVERT A SUBSTANTIAL PORTION OF THE KINETIC ENERGY OF SAID JETS INTO KINETIC ENERGY OF TURBULENT MOTION AND REDUCE THE SIZE OF THE FUEL DROPLETS, FLOWING THE FUEL AIR MIXTURE FROM THE TURBULENCE CHAMBER TO THE ENGINE CYLINDERS, AND AUTOMATICALLY APPROXIMATELY MAINTAINING A PREDETERMINED SUFFICIENT MINIMUM VELOCITY OF FLOW OF THE FUEL AIR JETS INTO THE TURBULENCE CHAMBER AT ALL ENGINE SPEEDS AND AT FULL POWER OPERATION TO OBTAIN SAID ENERGY CONVERSION.

Claim 4

A METHOD OF SUPPLYING A FUEL AIR MIXTURE TO CYLINDERS OF AN INTERNAL COMBUSTION ENGINE WHICH COMPRISES FLOWING THROUGH A CHANNEL AIR CONTAINING COARSE FUEL DROPLETS PAST A VARIABLE CONSTRICTION IN THE CHANNEL TO FORM HIGH VELOCITY JETS OF AIR CONTAINING FUEL DROPLETS, INJECTING SAID JETS IMMEDIATELY INTO THE CENTRAL PORTION OF A TURBULENCE CHAMBER HAVING A LARGER CROSS SECTION THAN SAID CHANNEL TO PREVENT SAID JETS IMPINGING ON THE WALLS OF SAID CHAMBER AND TO CONVERT A SUBSTANTIAL PORTION OF THE KINETIC ENERGY OF SAID JETS INTO KINETIC ENERGY OF TURBULENT MOTION AND REDUCE THE SIZE OF THE FUEL DROPLETS, FLOWING THE FUEL AIR MIXTURE FROM THE TURBULENCE CHAMBER TO THE ENGINE CYLINDERS, AND AUTOMATICALLY APPROXIMATELY MAINTAINING A PREDETERMINED SUFFICIENT MINIMUM VELOCITY OF FLOW OF THE FUEL AIR JETS INTO THE TURBULENCE CHAMBER AT ALL ENGINE SPEEDS AND AT FULL POWER OPERATION TO OBTAIN SAID ENERGY CONVERSION.
