As velas de igni\u00e7\u00e3o s\u00e3o respons\u00e1veis por gerar a fa\u00edsca que faz o combust\u00edvel explodir e o motor do ve\u00edculo girar. Esses componentes s\u00e3o relativamente baratos mas, se n\u00e3o estiverem funcionando perfeitamente, podem prejudicar o propulsor por causa do ac\u00famulo de res\u00edduos na c\u00e2mara de combust\u00e3o, por exemplo, al\u00e9m de aumento do consumo e dos n\u00edveis de emiss\u00f5es de poluentes.<\/p>\n

 <\/p>\n

Cabos de velas, bobinas e o catalisador tamb\u00e9m sofrer\u00e3o maior desgaste se as velas n\u00e3o estiverem em dia. Com isso, ter\u00e3o a durabilidade abreviada.<\/p>\n

 <\/p>\n

Segundo informa\u00e7\u00f5es da fabricante de autope\u00e7as NGK, as velas devem ser verificadas a cada 10 mil quil\u00f4metros. J\u00e1 a troca deve ser feita de acordo com indica\u00e7\u00e3o da montadora no manual do ve\u00edculo.<\/p>\n

 <\/p>\n

Os cabos devem ser checados juntamente com as velas. Eles conduzem a alta tens\u00e3o das bobinas para os componentes e, caso estejam desgastados, podem comprometer o funcionamento do sistema de igni\u00e7\u00e3o. \u00c9 comum defeitos nos cabos serem confundidos com problemas nas velas.<\/p>\n

 <\/p>\n

Falhas nas acelera\u00e7\u00f5es, vibra\u00e7\u00f5es excessivas no motor e aumento no consumo de combust\u00edvel s\u00e3o sintomas que podem indicar falhas nas velas. \u201cQuando o problema come\u00e7a a ser percebido, \u00e9 sinal de que est\u00e1 ocorrendo h\u00e1 algum tempo\u201d, diz o consultor de assist\u00eancia t\u00e9cnica da NGK, Hiromori Mori. Ele explica que os ve\u00edculos mais modernos \u201cv\u00e3o se adaptando\u201d \u00e0s falhas e demoram a apresentar sinais de defeito.<\/p>\n

 <\/p>\n

Um jogo com quatro velas para um Focus 2.0, por exemplo, custa R$ 76 nas autorizadas da Ford. A troca das pe\u00e7as \u00e9 simples e feita rapidamente, mas requer uma chave espec\u00edfica.<\/p>\n

 <\/p>\n

Outro cuidado importante \u00e9 respeitar as especifica\u00e7\u00f5es determinadas no manual do ve\u00edculo. Pe\u00e7as diferentes das originais causar\u00e3o falhas no funcionamento do motor.<\/p>\n

 <\/p>\n

As fabricantes do componente disp\u00f5em de tabelas de correspond\u00eancia para todos os modelos e suas respectivas op\u00e7\u00f5es de motor. Os cabos de vela tamb\u00e9m t\u00eam especifica\u00e7\u00f5es pr\u00f3prias, uma vez que varia\u00e7\u00f5es na pot\u00eancia e condutividade da eletricidade podem afetar as respostas do propulsor.
