Um dos maiores &#8220;defeitos&#8221; dos autom\u00f3veis antigos era a falta de um filtro para barrar o vapor t\u00f3xico ocasionado pela queima de combust\u00edvel. Toda essa mistura era expelida para fora do carro, prejudicando a qualidade do ar.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"> Assim, com a inten\u00e7\u00e3o de diminuir a emiss\u00e3o de poluentes, foi desenvolvido na d\u00e9cada de 90 o c\u00e2nister. Basicamente, a pe\u00e7a \u00e9 um reservat\u00f3rio de carv\u00e3o ativado conectada ao tanque de combust\u00edvel e ao motor. Ela armazena os gases de combust\u00edvel que evaporam do tanque e, quando o motor passa a funcionar, a v\u00e1lvula do c\u00e2nister \u00e9 acionada e o pr\u00f3prio motor queima os gases armazenados. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Nos ve\u00edculos com carburador, esse acionamento\u00a0\u00e9 feito pelo v\u00e1cuo criado quando o motor \u00e9 ligado. J\u00e1 nos carros mais novos, com inje\u00e7\u00e3o eletr\u00f4nica, o acionamento da v\u00e1lvula de c\u00e2nister tamb\u00e9m \u00e9 eletr\u00f4nico.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"534\" src=\"https:\/\/balconistasa.com\/wp-content\/uploads\/2021\/08\/fotomateria3-1.png\" alt=\"imagem de um c\u00e2nister \" class=\"wp-image-3171\"\/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Mesmo com a inten\u00e7\u00e3o de prevenir que gases t\u00f3xicos saiam do carro, a v\u00e1lvula de purga do c\u00e2nister, que atua no controle do fluxo dos gases acumulados absorvidos do tanque, pode dar dor de cabe\u00e7a ao motorista. Se ela for obstru\u00edda, ou se as mangueiras que conectam o c\u00e2nister ao motor e ao tanque romperem, a efici\u00eancia do sistema de emiss\u00e3o de poluente, assim como o desempenho do carro, ser\u00e1 afetado. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">No casos dos carros com sistema de inje\u00e7\u00e3o, isso pode levar o carro a entrar em modo de emerg\u00eancia, acionando a luz da inje\u00e7\u00e3o eletr\u00f4nica no painel. Outro problema \u00e9 o aumento do consumo de combust\u00edvel.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Existem algumas formas de <a href=\"http:\/\/balconistasa.com\/2017\/05\/10\/de-olho-no-escapamento\/\">identificar problemas no c\u00e2nister<\/a>. O mais comum \u00e9 o cheiro forte e constante de combust\u00edvel ap\u00f3s o funcionamento do ve\u00edculos mesmo sem sinais aparentes de vazamento. \u00c9 importante lembrar que, na maioria dos ve\u00edculos, a v\u00e1lvula fica localizada abaixo do para-lama. Por isso, no caso de uma colis\u00e3o, mesmo que leve, o c\u00e2nister pode ser danificado. <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Pe\u00e7a obrigat\u00f3ria \u00e9 respons\u00e1vel por filtrar poluentes<\/p>\n","protected":false},"author":1,"featured_media":3172,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[68],"tags":[607,252,558,608,214,609],"class_list":["post-9699","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-autopecas","tag-canister","tag-como-funciona","tag-funcionamento","tag-mecanicas","tag-pecas","tag-poluicao"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.6 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Como funciona o c\u00e2nister? - Balconista<\/title>\n<meta name=\"description\" content=\"Pe\u00e7a obrigat\u00f3ria \u00e9 respons\u00e1vel por filtrar poluentes, muito importante para o funcionamento do carro.
