Description

DISPOSITIVO PARA MEZCLAR COMBUSTIBLES CON INYECTORES DUALES EN MOTORES DE COMBUSTIÓN DEVICE FOR MIXING FUELS WITH DUAL INJECTORS IN COMBUSTION ENGINES
Campo de la Invención Field of Invention
La presente invención pertenece al campo de la mecánica de motores de combustión y su control de alimentación de combustible dual a reacción que consumen aire y particularmente con motores especialmente adaptados a la utilización de un combustible especial o de una variedad de combustibles mezclados; donde el dispositivo combina, no solo combustibles independientes, sino dos tipos combustibles simultáneos tomados de gasolina, diesel o nafta junto con combustibles gaseosos, que al momento de la detonación de la mezcla en la cámara de combustión con un inyector dual, dosifica la mezcla exacta de combustibles gaseosos y gasolinas por la entrada del ducto de combustibles gaseosos hacia la cámara de mezcla dual, entrando gasolina y combustible gaseoso mezclados a la cámara y controlando dicha mezcla por una válvula de aguja que se contrae por campo electromagnético de bobinas que vencen la fuerza de un muelle helicoidal. The present invention belongs to the field of the mechanics of combustion engines and their control of dual fuel supply to reaction that consume air and particularly with engines specially adapted to the use of a special fuel or of a variety of mixed fuels; where the device combines, not only independent fuels, but two simultaneous fuel types taken from gasoline, diesel or naphtha together with gaseous fuels, which at the moment of detonation of the mixture in the combustion chamber with a dual injector, dose the exact mixture of gaseous fuels and gasoline through the inlet of the gaseous fuel pipeline to the dual mixing chamber, entering gasoline and mixed gaseous fuel into the chamber and controlling said mixture by a needle valve that contracts by electromagnetic field of coils that overcome the force of a helical spring.
Antecedentes de la Invención Background of the Invention
Los motores que usan gasolina para impulsarse se les ha adaptado conversiones de gas natural vehicular, hoy en día se existen vehículos de combustible dual o conocidos con el nombre erróneo “híbridos" que usan gas natural vehicular dedicado y gasolina como segundo combustible, pero no combinado, aún siguen usando un solo combustible para el momento de la detonación de este en la cámara de combustión, bien sea gasolina, diésel o gas natural vehicular GNVC. En este sentido, existen inyectores denominados duales, que hacen aportes de combustible gaseoso a un sistema de combustible gasolina, pero no son una configuración de un solo inyector con función dual simultánea que permita mezclar dos o tres tipos de combustible y tampoco aportan una mezcla de combustible gaseoso y gasolina en una dosificación estratificada de combustible; mientras que la nueva invención, en una sola cámara y no mediante aportes independientes, mezcla combustibles gaseosos y combustibles líquidos con hasta tres combustibles como por ejemplo, gas vehicular, etanol y gasolina, con control electrónico de entrega de combustibles dosificados por un solo sistema. Por otro lado, se conoce de la invención el antecedente US9777646B2 “Inyección directa de diluyentes o combustibles secundarios en motores de combustible gaseoso” de Ford Global Technologies LLC de fecha 2017-10-03, que propone un método para operar un motor, que comprende inyectar en el puerto una primera cantidad de un primer combustible en un ciclo de cilindro e inyectando directamente una segunda cantidad de un inyéctate secundario en el ciclo del cilindro en función de un aire a gas relación (AFR), el AFR deseado basado en la temperatura de una válvula del cilindro del motor. El AFR deseado puede estar fuera del rango de AFR disponible durante combustión de gas natural solo y, por lo tanto, permite un funcionamiento más frío del motor. Este antecedente muestra dos inyectores dosificando uno u otro combustible, pero no la mezcla, mientras que el nuevo inyector dual dosifica dos combustibles a la misma vez en una sola cama y entregándola a la cámara de combustión ya mezclada con aire y combustible. The engines that use gasoline to propel themselves have been adapted to vehicular natural gas conversions, today there are dual fuel vehicles or known with the erroneous name "hybrids" that use dedicated vehicular natural gas and gasoline as a second fuel, but not combined , they still use only one fuel at the moment of its detonation in the combustion chamber, be it gasoline, diesel or CNG vehicular natural gas.In this sense, there are so-called dual injectors, which make contributions of gaseous fuel to a system of gasoline fuel, but they are not a configuration of a single injector with a simultaneous dual function that allows mixing two or three types of fuel, nor do they provide a mixture of gaseous fuel and gasoline in a fuel stratified dosage; while the new invention, in a single chamber and not through independent contributions, mixes gaseous fuels and liquid fuels with up to three combi ustibles such as vehicular gas, ethanol and gasoline, with electronic control of fuel delivery dosed by a single system. On the other hand, the antecedent US9777646B2 "Direct injection of diluents or secondary fuels in gaseous fuel engines" of Ford Global Technologies LLC dated 2017-10-03 is known about the invention, which proposes a method for operating an engine, comprising port injecting a first quantity of a first fuel into a cylinder cycle and directly injecting a second quantity of a secondary injectate into the cylinder cycle as a function of an air to gas ratio (AFR), the desired AFR based on temperature of an engine cylinder valve. Target AFR may be outside of the AFR range available during natural gas combustion alone and therefore allows for cooler engine operation. This background shows two injectors dosing one or the other fuel, but not the mixture, while the new dual injector doses two fuels at the same time in a single bed and delivering it to the combustion chamber already mixed with air and fuel.
El antecedente US7628137B1 “Sistema de almacenamiento, medición y encendido de múltiples combustibles” de McAlister Technologies LLC, Advanced Green Innovations LLC de 2007-11 -20, es un sistema para el almacenamiento seguro y la utilización eficiente de una variedades de gasolina, donde se proporciona una selección de gasolina que que varían de composición y fase, desde mezclas criogénicas de sólidos y líquidos hasta gases a temperatura elevada para aplicaciones únicas con varios tipos de motores térmicos y gasolinas en combinaciones hibridadas. A diferencia de la nueva invención, que no propone un inyector dosificando múltiples combustibles a modo independiente, sino que propone un inyector dual de mezcla dos tipos de combustible tomados de combustible gaseoso y gasolina en una mezcla homogénea sin los perjuicios de que la mezcla apague el funcionamiento del motor. Background US7628137B1 "Multi-Fuel Storage, Metering, and Ignition System" by McAlister Technologies LLC, Advanced Green Innovations LLC of 2007-11-20, is a system for the safe storage and efficient utilization of a variety of gasoline, where provides a selection of gasolines that vary in composition and phase, from cryogenic mixtures of solids and liquids to gases at elevated temperature for unique applications with various types of combustion engines and gasolines in hybrid combinations. Unlike the new invention, which does not propose an injector dosing multiple fuels independently, but instead proposes a dual injector mixing two types of fuel taken from gaseous fuel and gasoline in a homogeneous mixture without the damages that the mixture turns off the engine operation.
Otra propuesta de mezcla está presente en la patente US9422899B2 “Inyector de combustible doble con sello de bloqueo hidráulico y estrategia de purga de fugas de líquido” de Caterpillar Inc y de fecha 2016-08-23; que muestra un sistema doble de combustible incluye un doble inyector que ha dispuesto en él una cámara de boquilla gaseosa conectada de forma fluida a una entrada de gasolina, y una cámara de boquilla de líquido conectada de forma fluida al líquido de entrada. El inyector doble también incluye un sello de bloqueo hidráulico con un volumen anular de líquido gasolina que rodea un segmento de guía de un gas miembro de válvula de aguja para inhibir la migración de gases combustibles en el líquido gasolina. Una entrada común de combustible gaseoso que está conectada a una entrada de flujo de gasolina, una válvula de retención se coloca entre el fluido de los gases combustibles y la cámara de boquilla gaseosa del doble inyector para bloquear la gasolina que se filtra en una cámara de boquilla gaseosa a través del sello de bloqueo hidráulico para que no entre en el gas combustible. La nueva invención no propone bloqueos para accesos de uno u de otro combustible, por el contrario, aporta una mezcla estequiométrica de combustibles, es decir que no son dos inyectores haciendo aportes de combustible para mezclándolos posteriormente en la cámara de combustión haciendo aportes de una mezcla heterogénea, sino que propone un solo inyector dual que hace mezcla homogénea en un solo competente, con un único inyector mezclando combustibles gaseosos al 75% y gasolina al 25% por control de una unidad de control electrónica y pulsos electromagnéticos. Another mixture proposal is present in the patent US9422899B2 "Dual fuel injector with hydraulic locking seal and liquid leak purge strategy" of Caterpillar Inc and dated 2016-08-23; showing a dual fuel system includes a dual injector having arranged therein a gas nozzle chamber fluidly connected to a gasoline inlet, and a liquid nozzle chamber fluidly connected to the inlet liquid. The dual injector also includes a hydraulic lock seal with an annular volume of gasoline liquid surrounding a guide segment of a gas needle valve member to inhibit fuel injection. migration of combustible gases in the gasoline liquid. A common gaseous fuel inlet which is connected to a gasoline flow inlet, a check valve is placed between the flow of fuel gases and the gaseous nozzle chamber of the dual injector to block gasoline leaking into a fuel chamber. gaseous nozzle through the hydraulic lock seal so that it does not enter the fuel gas. The new invention does not propose blockages for access of one or the other fuel, on the contrary, it provides a stoichiometric mixture of fuels, that is to say that there are not two injectors making fuel contributions to mix them later in the combustion chamber making contributions of a mixture heterogeneous, but proposes a single dual injector that makes a homogeneous mixture in a single competent, with a single injector mixing 75% gaseous fuels and 25% gasoline by control of an electronic control unit and electromagnetic pulses.
La presente invención presenta un dispositivo para la mezcla de combustible gaseoso con gasolina, donde el combustible gaseoso es tomado de gas de carbón, gas pobre, biogás, gas de vertedero o gas natural y la gasolina es un combustible nafta en estado líquido. El combustible gaseoso y la gasolina o nafta son apolares y su electronegatividad no les permite mezclarse; por lo que cuando se intenta adicionar gasolina en la combustión de combustible gaseoso el motor se apaga. La invención soluciona esta falencia de electronegatividad para que los combustibles se mezclen sin que el motor se apague, adaptando a los mecanismos originales del vehículo de gasolina el dispositivo convirtiendo el motor en un mecanismo de mezcla con combustible gaseoso, como un mecanismo asertivamente híbrido de gasolina combinada con combustible gaseoso para que su vida útil se prolongue por más de 4.000 horas y funcione hasta por 8.760 horas año como funcionan los motores en la industria pesada de combustible gaseoso que tienen trabajo continuo a plena carga durante períodos cercanos a las 8.760 horas por año.
