Sensor de masa de aire ( MAF )<\/strong><\/p>\n

 <\/p>\n

El motor de combusti\u00f3n interna de un autom\u00f3vil necesita aire y combustible para funcionar correctamente. La relaci\u00f3n aire-combustible debe ser \u00f3ptima para garantizar una combusti\u00f3n ininterrumpida y un mayor rendimiento del motor.<\/p>\n

En el pasado, un carburador era el \u00fanico dispositivo que controlaba la combinaci\u00f3n de aire y combustible. Cuando se inventaron las modernas unidades de control del motor (ECU), tambi\u00e9n conocidas como m\u00f3dulos de control del motor, cambiaron el sistema de forma significativa. Los sensores de masa de aire (MAF) se utilizan para medir el caudal de aire.<\/p>\n

 <\/p>\n

Qu\u00e9 es un sensor MAF:<\/strong><\/p>\n

Un sensor de masa de aire tambi\u00e9n se conoce como un medidor de aire . Desempe\u00f1a un papel vital en su veh\u00edculo. Concretamente, mide la cantidad de aire (caudal m\u00e1sico de aire) que entra en el motor de combusti\u00f3n interna.<\/p>\n

Bas\u00e1ndose en estas entradas en tiempo real, la unidad de control del motor estima la cantidad de masa de combustible necesaria para mantener el equilibrio entre el aire y el combustible.<\/p>\n

Adem\u00e1s, hay que tener en cuenta que la densidad del aire cambia con la temperatura, la presi\u00f3n, la humedad, etc. Aqu\u00ed tambi\u00e9n ayudan los sensores MAF. Cuando se trata de medir la cantidad de aire admitido en cada cilindro, son m\u00e1s precisos que los sensores de flujo volum\u00e9trico.<\/p>\n

 <\/p>\n

Tipos de sensores MAF:<\/strong><\/p>\n

 <\/p>\n

Caudal\u00edmetros de paletas <\/u>son un tipo m\u00e1s antiguo de sensor de flujo de aire. Se clasifican a su vez en VAF, voltaje, se\u00f1al y sensores de flujo de aire Karman Vortex. Este \u00faltimo es m\u00e1s nuevo en dise\u00f1o. Utiliza un espejo m\u00f3vil y un fototransistor para medir el flujo de aire.<\/p>\n

MAF alambre caliente sensores de flujo de aire<\/u> son sensores MAF avanzados y son m\u00e1s comunes. Se componen de un termistor, un cable caliente de platino y un circuito de control electr\u00f3nico. El termistor es un sensor de temperatura que mide la temperatura del aire. Un circuito de control electr\u00f3nico mantiene un hilo caliente de platino a una temperatura constante. Cuando el aire entra en contacto con el hilo caliente, \u00e9ste se enfr\u00eda. Cuando la diferencia de temperatura entre los dos cables cambia, el sensor MAF autom\u00e1ticamente aumenta o disminuye la corriente al cable caliente.<\/p>\n

Tambi\u00e9n los hay, sensores de flujo de aire de hilo fr\u00edo <\/u>que funcionan de forma similar a sus hom\u00f3logos de hilo caliente. Sin embargo, tienen una resistencia adicional al fr\u00edo que les permite medir el aire ambiente.<\/p>\n

 <\/p>\n

Signos de un sensor MAF defectuoso:<\/strong><\/p>\n

 <\/p>\n

Identificar los problemas de funcionamiento del sensor MAF puede ser un reto porque no son f\u00e1ciles de detectar. Estos son algunos de los s\u00edntomas m\u00e1s comunes de un sensor MAF defectuoso:<\/p>\n

Un mal funcionamiento del sensor MAF puede dar lugar a una variedad de problemas de conducci\u00f3n tales como calado del motor, tirones o vacilaci\u00f3n al acelerar. Puede experimentar estos problemas al acelerar.<\/p>\n

 <\/p>\n

\u00bfPor qu\u00e9 surgen los problemas?<\/strong><\/p>\n

 <\/p>\n

Los residuos de la carretera, el polvo, la suciedad y otros contaminantes que pasan a trav\u00e9s del filtro de aire pueden recubrir los cables del sensor MAF e impedir que mida con precisi\u00f3n el flujo de aire. Puede enviar informes inexactos del flujo de aire a bajas velocidades. Como ya se ha explicado, cuando el sensor MAF no funciona correctamente, el motor no puede mezclar aire y combustible en la proporci\u00f3n adecuada.<\/p>\n

Por lo tanto, limpiar el sensor MAF puede ser un buen punto de partida. Sin embargo, para garantizar la seguridad de su veh\u00edculo, considere la posibilidad de que lo revise un mec\u00e1nico.<\/p>\n

 <\/p>\n

Conclusiones:<\/strong><\/p>\n

El sensor de masa de aire es esencial para el funcionamiento \u00f3ptimo del motor de combusti\u00f3n interna de su veh\u00edculo. Bas\u00e1ndose en la medici\u00f3n del flujo de aire, la ECU equilibra el aire y el combustible.<\/p>\n

 <\/p>\n

En otras palabras, sin un sensor MAF, el coche no funcionar\u00eda.<\/p>\n

Por eso es necesario revisarlo y mantenerlo correctamente. Afortunadamente, los sensores MAF son relativamente baratos de reemplazar.<\/p>","protected":false},"excerpt":{"rendered":"

Senzorul de debit de aer in masa \u2013 Mass Air Flow ( MAF )   Motorul cu ardere intern\u0103 al unei ma\u0219ini necesit\u0103 at\u00e2t aer, c\u00e2t \u0219i combustibil pentru a func\u021biona corect. Raportul aer-combustibil trebuie s\u0103 fie optim pentru a asigura arderea ne\u00eentrerupt\u0103 \u0219i performan\u021ba \u00eembun\u0103t\u0103\u021bit\u0103 a motorului. \u00cen trecut, un carburator era singurul dispozitiv care controla combina\u021bia de aer \u0219i combustibil. C\u00e2nd au fost inventate unit\u0103\u021bile moderne de control al motorului (ECU), cunoscute \u0219i sub numele de module de control al motorului, acestea au schimbat semnificativ sistemul. Senzorii Mass Air Flow (MAF) se folosesc pentru a m\u0103sura fluxul de aer.   Ce este un senzor MAF: Un senzor de debit de aer \u00een mas\u0103 este cunoscut \u0219i sub numele de contor de aer . Acesta joac\u0103 un rol fundamental \u00een vehiculul dumneavoastr\u0103. \u0218i anume, m\u0103soar\u0103 cantitatea de aer (debitul de mas\u0103 de aer) care intr\u0103 \u00een motorul cu ardere intern\u0103 . Pe baza acestor intr\u0103ri \u00een timp real, unitatea de control al motorului estimeaz\u0103 cantitatea de mas\u0103 de combustibil necesar\u0103 pentru a men\u021bine aerul \u0219i combustibilul \u00een echilibru. \u00cen plus, re\u021bine\u021bi c\u0103 densitatea aerului se modific\u0103 odat\u0103 cu temperatura, presiunea, umiditatea etc. Aici, din nou, senzorii MAF ajut\u0103. C\u00e2nd vine vorba de m\u0103surarea cantit\u0103\u021bii de aer admis \u00een fiecare cilindru, ace\u0219tia sunt mai precisi dec\u00e2t senzorii de debit volumetric .   Tipuri de senzori MAF:   Debitmetrele cu palete sunt un tip mai vechi de senzori de debit de aer. Acestea sunt clasificate \u00een continuare \u00een senzori de debit de aer VAF, de tensiune, de semnal \u0219i Karman Vortex . Acesta din urm\u0103 este mai nou \u00een design. Folose\u0219te o oglind\u0103 mobil\u0103 \u0219i un fototranzistor pentru a m\u0103sura fluxul de aer. Senzorii MAF de flux de aer cu fir fierbinte sunt senzori MAF avansa\u021bi \u0219i sunt mai des \u00eent\u00e2lni\u021bi. Acestia constau dintr-un termistor, un fir fierbinte de platin\u0103 \u0219i un circuit de control electronic. Termistorul este un senzor de temperatur\u0103 care m\u0103soar\u0103 temperatura aerului. Un circuit electronic de control men\u021bine un fir fierbinte de platin\u0103 la o temperatur\u0103 constant\u0103. C\u00e2nd aerul intr\u0103 \u00een contact cu firul \u00eenc\u0103lzit, acesta se r\u0103ce\u0219te. C\u00e2nd diferen\u021ba de temperatur\u0103 dintre cele dou\u0103 fire se modific\u0103, senzorul MAF cre\u0219te sau scade automat curentul c\u0103tre firul fierbinte. Exist\u0103, de asemenea, senzori de flux de aer cu fir rece care func\u021bioneaz\u0103 similar cu omologii lor cu fir fierbinte. Cu toate acestea, au o rezisten\u021b\u0103 suplimentar\u0103 la rece care le permite s\u0103 m\u0103soare aerul ambiental.   Semnele unu senzor MAF defect:   Identificarea problemelor de performan\u021b\u0103 a senzorului MAF poate fi o provocare, deoarece nu sunt u\u0219or de detectat. Iat\u0103 c\u00e2teva dintre cele mai comune simptome ale unui senzor MAF defect: Un senzor MAF care func\u021bioneaz\u0103 defectuos poate duce la o varietate de probleme de conducere, cum ar fi blocarea motorului, smucirea sau ezitarea \u00een timp ce accelera\u021bi. Este posibil s\u0103 \u00eent\u00e2mpina\u021bi aceste probleme \u00een timp ce accelera\u021bi.   De ce apar probleme?   Resturile de pe drum, praful, murd\u0103ria \u0219i al\u021bi contaminan\u021bi care trec prin filtrul de aer pot acoperi firele senzorului MAF \u0219i \u00eel pot \u00eempiedica s\u0103 m\u0103soare cu precizie fluxul de aer. Poate trimite rapoarte inexacte ale fluxului de aer la viteze mai mici. Dup\u0103 cum am explicat deja, atunci c\u00e2nd senzorul MAF nu func\u021bioneaz\u0103 corect, motorul nu poate amesteca aerul \u0219i combustibilul \u00een raportul corespunz\u0103tor. Prin urmare, cur\u0103\u021barea senzorului MAF poate fi un bun punct de plecare. Cu toate acestea, pentru a va asigura de \u00a0siguran\u021ba vehiculului dvs., lua\u021bi \u00een considerare verificarea de catre un mecanic.   Concluzii: Senzorul de debit de aer \u00een mas\u0103 este esen\u021bial pentru func\u021bionarea optim\u0103 a motorului cu ardere intern\u0103 al vehiculului dumneavoastr\u0103. Pe baza m\u0103sur\u0103rii debitului de aer, ECU echilibreaz\u0103 aerul \u0219i combustibilul.   Cu alte cuvinte, f\u0103r\u0103 un senzor MAF, ma\u0219ina nu ar func\u021biona. Tocmai de aceea trebuie s\u0103 \u00eel verifica\u021bi \u0219i s\u0103 \u00eel \u00eentre\u021bine\u021bi corespunz\u0103tor. Din fericire, senzorii MAF sunt relativ ieftin de \u00eenlocuit.<\/p>","protected":false},"author":1,"featured_media":3284,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"default","ast-site-content-layout":"","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center
