Se um injetor common rail estiver bloqueado por impurezas, como detect\u00e1-lo? Pontos de solu\u00e7\u00e3o de problemas do injetor common rail – testador de injetor common rail:<\/p>\n

    \n
  1. Se estiver usando um sanner de diagn\u00f3stico para verificar, n\u00e3o h\u00e1 c\u00f3digo de falha ou o conte\u00fado do c\u00f3digo de falha n\u00e3o tem nada a ver com o injetor; \u00fc<\/li>\n
  2. A press\u00e3o do trilho pode atingir mais de 25 MPa durante a partida; \u00fc<\/li>\n
  3. O circuito do injetor tem um sinal de tens\u00e3o de pulso.<\/li>\n<\/ol>\n

    Testador de injetor common rail – pontos de verifica\u00e7\u00e3o de injetor preso:<\/p>\n

      \n
    1. Nenhum c\u00f3digo de falha ou conte\u00fado de c\u00f3digo de falha \u00e9 irrelevante para o injetor ao usar um scanner de diagn\u00f3stico.<\/li>\n
    2. A press\u00e3o do trilho pode ser estabelecida na partida, mas n\u00e3o pode atingir 25 MPa (sem tens\u00e3o de pulso no injetor);<\/li>\n
    3. Quando o motor n\u00e3o d\u00e1 partida, o injetor common rail n\u00e3o tem quantidade de retorno. \u00fc<\/li>\n
    4. Ap\u00f3s a partida, remova o injetor common rail e h\u00e1 sinais de inje\u00e7\u00e3o de combust\u00edvel na extremidade dianteira do injetor.<\/li>\n<\/ol>\n

      O refluxo do injetor common rail est\u00e1 muito maior do que o normal:<\/p>\n

        \n
      1. 1, nenhum c\u00f3digo de falha ou o conte\u00fado do c\u00f3digo de falha n\u00e3o tem nada a ver com o injetor; \u00fc<\/li>\n
      2. 2, o circuito de \u00f3leo de baixa press\u00e3o est\u00e1 normal; \u00fc<\/li>\n
      3. 3, a press\u00e3o do trilho n\u00e3o pode atingir 25 MPa;<\/li>\n
      4. Desconecte o injetor de combust\u00edvel do tubo de retorno de combust\u00edvel e verifique qual \u00e9 o maior fluxo de retorno<\/li>\n
      5. Se voc\u00ea verificar qual injetor tem uma grande quantidade de retorno de combust\u00edvel, poder\u00e1 substituir o injetor um a um para ver se o fen\u00f4meno da falha desaparece.<\/li>\n<\/ol>\n

        Observa\u00e7\u00e3o: Em circunst\u00e2ncias normais, quando o injetor n\u00e3o estiver energizado, o injetor come\u00e7ar\u00e1 a retornar quando a press\u00e3o do trilho atingir 60 MPa.<\/p>\n<\/div><\/section>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":239504,"featured_media":4536,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_monsterinsights_skip_tracking":false,"footnotes":""},"categories":[43],"tags":[],"class_list":["post-4616","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-nao-categorizado"],"yoast_head":"\nBanco
