Homogeneous fuel-air-mix method and apparatus for internal combustion engines

摘要

New strategies for control and feeding of air/fuel homogenous mix for internal combustion engines, mainly for fuel injection engines. This new strategies are to get an air/fuel mixture homogeneous and of adequate volume. Fuel in contact with air for a sufficient length of time required for better physical combination prior to the time of ignition at the spark plug and of a volume such that the combustion flame can reach the entire mixture admitted. Strategies to prevent the problem known as “wet wall”. This consisting of a new intake manifold, new fuel injectors, injector nozzles and new algorithms and strategies in the control software program of the ECU or MCU controlling the internal combustion engines.

1. A homogeneous air-fuel mixture system for an internal combustion engine having at least one combustion chamber and at least one intake valve operatively connected to said at least one combustion chamber, comprising:
an air intake manifold comprising a section having a substantially circular cross-sectional configuration, a first upstream section defined around a first longitudinal axis, fluidically connected to a source of air, and fixedly connected to a first arcuate section of said section of said air intake manifold having said substantially circular cross-sectional configuration, and a second downstream section defined around a second longitudinal axis different from said first longitudinal axis, fluidically connected to said at least one intake valve of said at least one combustion chamber of said internal combustion engine, and fixedly connected to a second arcuate section of said section of said air intake manifold having said substantially circular cross-sectional configuration; a fuel injector assembly for injecting fuel outwardly from a fuel injector dispensing exit into said air intake manifold at a point proximate to the location at which said first upstream section of said air intake manifold joins said second downstream section of said air intake manifold and at which said first longitudinal axis of said first upstream section of said air intake manifold intersects said second longitudinal axis of said second downstream section of said air intake manifold; and a support structure mounting said fuel injector upon said section of said air intake manifold having said substantially circular cross-sectional configuration, annularly surrounding said fuel injector dispensing exit, projecting axially away from said fuel injector dispensing exit, extending into the air space of said section of said air intake manifold having said substantially circular cross-sectional configuration at said point proximate to said location at which said first upstream section of said air intake manifold joins said second downstream section of said air intake manifold and at which said first longitudinal axis of said first upstream section of said air intake manifold intersects said second longitudinal axis of said second downstream section of said air intake manifold, and extending coxially with respect to said second downstream section of said air intake manifold along said longitudinal axis of said second downstream section of said air intake manifold so as to effectively initially confine said injected fuel to a spray pattern having a predeterminedly narrow width dimension along said second longitudinal axis of said second downstream section of said air intake manifold and wherein surrounding intake air will mix with said injected fuel so as to form an air-fuel mixture with said injected fuel and which will further aid in confining said injected fuel to a spray pattern having a predetermined width dimension along said second longitudinal axis of said second downstream section of said air intake manifold such that said air-fuel mixture will effectively be prevented from approaching interior wall portions of said second downstream section of said air intake manifold leading to said at least one intake valve of said at least one combustion chamber of said internal combustion engine until said air-fuel mixture is immediately adjacent said at least one combustion chamber of said internal combustion engine.
