<\/p>\nCapteurs de position du papillon des gaz - TPS<\/p>\n
<\/p>\n
Le syst\u00e8me d'acc\u00e9l\u00e9rateur des voitures surveille et contr\u00f4le le flux de fluide dans le moteur. La puissance du moteur du v\u00e9hicule peut \u00eatre contr\u00f4l\u00e9e en modifiant le rapport air-carburant du moteur, ce qui est fait par les contraintes du papillon des gaz. Les voitures modernes fonctionnent avec un syst\u00e8me de conduite par c\u00e2ble. Dans ce syst\u00e8me, les capteurs ont remplac\u00e9 de nombreux syst\u00e8mes m\u00e9caniques des voitures. Une unit\u00e9 informatis\u00e9e, appel\u00e9e unit\u00e9 de contr\u00f4le du moteur, surveille les donn\u00e9es d\u00e9riv\u00e9es de divers capteurs et contr\u00f4le la voiture. L'un de ces capteurs automobiles est le capteur de position du papillon des gaz.<\/p>\n
Qu'est-ce qu'un capteur de position du papillon des gaz ?<\/p>\n
Dans les voitures, le r\u00e9gime du moteur peut \u00eatre contr\u00f4l\u00e9 en variant la quantit\u00e9 de carburant et d'air fournie au moteur. Dans le pass\u00e9, une liaison m\u00e9canique \u00e9tait attach\u00e9e \u00e0 la p\u00e9dale d'acc\u00e9l\u00e9rateur pour contr\u00f4ler le papillon des gaz. Lorsque le conducteur appuyait sur le c\u00e2ble de l'acc\u00e9l\u00e9rateur, le papillon s'ouvrait en grand, provoquant un flux important de carburant ou d'air, ce qui augmentait la vitesse du v\u00e9hicule.<\/p>\n
Dans les voitures modernes, le capteur de position du papillon des gaz est utilis\u00e9 pour ce processus. Ce capteur est utilis\u00e9 pour surveiller la position du papillon des gaz dans les v\u00e9hicules. Il peut \u00e9galement \u00eatre consid\u00e9r\u00e9 comme un potentiom\u00e8tre qui fournit une r\u00e9sistance variable en fonction de la position du papillon des gaz.<\/p>\n
Principe de fonctionnement<\/p>\n
Ce capteur est g\u00e9n\u00e9ralement mont\u00e9 sur le corps de la valve. Il d\u00e9tecte la position du papillon des gaz ou de la vanne papillon et transmet l'information \u00e0 l'unit\u00e9 de contr\u00f4le du moteur. Ce capteur surveille la force avec laquelle la p\u00e9dale d'acc\u00e9l\u00e9rateur est enfonc\u00e9e et fournit le courant de sortie qui d\u00e9termine la position de la p\u00e9dale. La position de la p\u00e9dale contr\u00f4le le flux d'air du moteur. Si la soupape est grande ouverte, le moteur re\u00e7oit plus d'air et vice versa. La sortie de ce capteur, ainsi que d'autres capteurs, est transmise \u00e0 l'unit\u00e9 de contr\u00f4le du moteur, qui d\u00e9cide de la quantit\u00e9 de carburant \u00e0 injecter dans le moteur.
\nCe capteur est un potentiom\u00e8tre \u00e0 trois fils. Par le premier fil, une alimentation de 5V est fournie \u00e0 la couche r\u00e9sistive des capteurs. Le deuxi\u00e8me fil est utilis\u00e9 comme masse, tandis que le troisi\u00e8me fil est connect\u00e9 au racleur du potentiom\u00e8tre et fournit une entr\u00e9e au syst\u00e8me de contr\u00f4le du moteur.
\nEn fonction de leur construction, il existe trois types de capteurs de position du papillon des gaz. Il s'agit des capteurs de position du papillon avec interrupteurs de fin de course int\u00e9gr\u00e9s, \u00e9galement connus sous le nom de capteurs de position du papillon ferm\u00e9, du type potentiom\u00e8tre et de la combinaison des deux types.<\/p>\n
Applications<\/p>\n
Le capteur fournit \u00e0 l'unit\u00e9 de contr\u00f4le du moteur des informations sur la position de la vanne papillon. Il est utilis\u00e9 pour d\u00e9tecter la position de ralenti, l'\u00e9tat d'ouverture du papillon. Lorsque la vanne est en position de ralenti, la tension de sortie du capteur est inf\u00e9rieure \u00e0 0,7 V. Lorsque la pleine charge est d\u00e9tect\u00e9e, la tension de sortie du capteur est d'environ 4,5 V.
\nUne d\u00e9t\u00e9rioration du capteur de position du papillon des gaz entra\u00eene le clignotement du signal Check Engine. Lorsque ce capteur est d\u00e9fectueux, l'ordinateur ne peut pas d\u00e9terminer correctement la position de la soupape, ce qui entra\u00eene une surtension ou le calage du v\u00e9hicule.<\/p>","protected":false},"excerpt":{"rendered":"
Senzori de pozi\u021bie a clapetei de accelera\u021bie – TPS Sistemul de accelera\u021bie prezent \u00een automobile monitorizeaz\u0103 \u0219i controleaz\u0103 fluxul de fluid \u00een motor.\u00a0Puterea motorului vehiculului poate fi controlat\u0103 prin schimbarea raportului aer-combustibil al motorului, care se face prin constr\u00e2ngerile clapetei de accelera\u021bie. Automobilele moderne func\u021bioneaz\u0103 pe sistemul drive-by-wire.\u00a0Aici, \u00een acest sistem, senzorii au \u00eenlocuit multe sisteme mecanice din automobile.\u00a0O unitate computerizat\u0103 numit\u0103 Unitatea de control al motorului monitorizeaz\u0103 datele derivate de la diferi\u021bi\u00a0senzori\u00a0\u0219i controleaz\u0103 automobilul.\u00a0Unul dintre acesti senzori auto\u00a0este senzorul de pozi\u021bie a accelera\u021biei. Ce este un senzor de pozi\u021bie a clapetei de accelera\u021bie? \u00cen automobile, viteza motorului poate fi controlat\u0103 variind cantitatea de combustibil \u0219i aer furnizate motorului. Anterior, la pedala de accelera\u021bie era ata\u0219at\u0103 o leg\u0103tur\u0103 mecanic\u0103 prin care era controlat\u0103 supapa fluture a sistemului de accelera\u021bie.\u00a0C\u00e2nd \u0219oferul love\u0219te cablul de accelera\u021bie, supapa se deschidea larg, ceea ce provoac\u0103 un debit mare de combustibil sau aer, cresc\u00e2nd astfel viteza vehiculului. \u00cen automobilele moderne, senzorul de pozi\u021bie a accelera\u021biei este utilizat pentru acest proces.\u00a0Acest senzor este folosit pentru a monitoriza pozi\u021bia supapei de accelera\u021bie \u00een vehicule.\u00a0Poate fi v\u0103zut \u0219i ca un poten\u021biometru care ofer\u0103 rezisten\u021b\u0103 variabil\u0103 \u00een func\u021bie de pozi\u021bia supapei de accelera\u021bie. Principiul de func\u021bionare Acest senzor este de obicei montat pe corpul clapetei.\u00a0Sesizeaz\u0103 pozi\u021bia clapetei de accelera\u021bie sau a supapei fluture \u0219i transmite informa\u021biile c\u0103tre unitatea de comand\u0103 a motorului.\u00a0Acest senzor monitorizeaz\u0103 c\u00e2t de tare este ap\u0103sat\u0103 pedala accelerometrului \u0219i ofer\u0103 curentul de ie\u0219ire care determin\u0103 pozi\u021bia pedalei.\u00a0Pozi\u021bia pedalei controleaz\u0103 fluxul de aer al motorului.\u00a0Dac\u0103 supapa este larg deschis\u0103, motorului ii este furnizat\u0103 o cantitate mare de aer \u0219i invers.\u00a0Ie\u0219irea dat\u0103 de acest senzor, \u00eempreun\u0103 cu al\u021bi senzori, este transmis\u0103 unit\u0103\u021bii de control a motorului, care decide cantitatea de combustibil care trebuie injectat\u0103 \u00een motor. Acest senzor este un\u00a0poten\u021biometru\u00a0cu trei fire .\u00a0Prin primul fir, o putere de 5V este furnizat\u0103 stratului rezistiv al senzorilor.\u00a0Al doilea fir este folosit ca mas\u0103, \u00een timp ce al treilea fir este conectat la \u0219terg\u0103torul poten\u021biometrului \u0219i ofer\u0103 intrare la sistemul de control al motorului. Pe baza construc\u021biei sale, exist\u0103 trei tipuri de senzori de pozi\u021bie a clapetei de accelera\u021bie.\u00a0Ace\u0219tia sunt senzori de pozi\u021bie a clapetei de accelera\u021bie cu comutatoare de cap\u0103t \u00eencorporate, cunoscu\u021bi \u0219i sub numele de Senzor de pozi\u021bie a clapetei de accelera\u021bie \u00eenchise, tip poten\u021biometru \u0219i combina\u021bia dintre ambele tipuri.

Deteriorarea senzorului de pozi\u021bie a accelera\u021biei duce la clipirea semnalului Check Engine.\u00a0C\u00e2nd acest senzor este defect, computerul nu a putut determina corect pozi\u021bia supapei, ceea ce duce la supratensiune sau blocarea vehiculului.<\/p>","protected":false},"author":1,"featured_media":3656,"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
