Abstract
Vanes in an air duct, independently controlled, one by the engine operator and others by environmental factors, generate vortices determining the speed of a turbine and thereby the flow of fuel through a fuel meter and fuel valves into prechambers for vaporization and mixing with spiraling air.
Claims10
An arrangement for supplying fuel and air in dependence of operational and environmental conditions to an internal combustion engine, comprising in combination
- an air duct for delivering air to said engine;
- air control means, including
- a throttle plate for controlling air flow in said air duct, means for controlling said throttle plate,
- a plurality of vanes movably mounted in said air duct for generating air vortices,
- means for controlling each of said vanes independently,
- means for measuring air speed and vorticity in said air duct;
- fuel flow control means, including
- a floatbowl containing fuel under near-ambient pressure, means for metering fuel flow,
- at least one fuel valve receiving said metered fuel flow, venting means between said fuel valve and said floatbowl for holding pressures within said fuel flow control means at near-ambient,
- a manifold interconnecting said means for metering fuel flow and said fuel valve;
- means for coupling said means for measuring air speed and vorticity with said means for metering fuel flow;
- whereby said fuel flow control means are governed by said air control means, wherein said means for measuring air speed and vorticity are controlled by said throttle plate and said vanes in said dependence of operational and environmental conditions.
An arrangement for supplying fuel and air in dependence of operational and environmental conditions to an internal combustion engine, having at least one combination of a cylinder, a piston cyclically performing intake, compression, expansion and exhaust strokes, an air intake valve providing air to said cylinder, a fuel valve receiving and holding fuel and vent air under near-ambient pressure, and a valve train operating said intake valve and said fuel valve, comprising
- fuel flow control means, including
- a floatbowl containing fuel under near-ambient pressure, means for metering fuel flow,
- at least one fuel valve receiving said metered fuel flow, venting means connecting said fuel valve and said floatbowl,
- a manifold interconnecting said means for metering fuel flow and said fuel valve;
- at least one fuel apportioning means, including
- a plunger in said fuel valve,
- plunger actuation means on said valve train,
- a checkvalve for controlling the flow direction of said fuel and said vent air,
- said plunger cutting said fuel flow from said fuel control means into increments and expulsing said increments together with said vent air from said fuel valve;
- at least one mixture control means, including
- a prechamber with circular crossection for vaporizing said fuel increments,
- a tube interconnecting said checkvalve and said prechamber for delivering said fuel increments from said fuel valve to said prechamber,
- means for generating spiral flows in said prechamber for vaporizing and mixing said fuel increments with said air, including a first port and a second port, displaced laterally and angularly from each other, with axes tangential to the circumference of said prechamber,
- said first port facing the air flow from said intake valve and said second port oriented to prevent said air flow from entering said prechamber through said second port;
- said first port directing said air flow into a first spiral flow in said prechamber during said intake strokes, said first and second ports generating a second spiral flow and a third spiral flow opposing said second spiral flow in said prechamber during said compression strokes.
