Muitos entusiastas de automóveis podem ter dúvidas: as velas de ignição devem ser substituídas durante a manutenção? How often do I change the velas de ignição?
O proprietário de um carro relatou um problema de reparo: potência insuficiente durante a condução, vibração ociosa severa, e alto consumo de combustível.

Como mostrado na imagem: Volkswagen Sagitar usa um 60000 vela de ignição quilométrica, que fica preto e os contatos já foram queimados. Combustão deficiente leva a energia insuficiente, falta de resposta do cilindro, uma série de solavancos durante a condução, e alto consumo de combustível.
Como nossas peças de carro, a maioria deles usa linhas de vida, como velas de ignição. Different materials and brands have different life cycles.
1. Nickel alloy spark plugs 20000 para 30000 quilômetros
2. 40000 kilometers of single platinum spark plugs
3. Dual platinum spark plugs 60000 quilômetros
4. Iridium spark plugs, 80000 quilômetros, etc.
The service life of these spark plugs is only recommended by the parts manufacturer. Na verdade, the vehicle model and driving habits will have an impact on the service life of the spark plugs, so it is judged that if the spark plugs are not replaced.
Personally, it is recommended to disassemble and inspect the spark plugs every 3 years or 60000 kilometers to determine whether to replace them based on their color and contact spacing.
4S stores also have some repair garages that replace them according to the maintenance manual, which saves time, but it’s not easy to make money. It’s better to check and see the specific condition of the quality before making a decision.

 

There may be many car enthusiasts who see this, but what are the consequences of not replacing the spark plugs?

1. Insufficient power and idle shaking: A decrease in spark plug performance will cause a linear decrease in the engine’s ignition performance, resulting in weak acceleration, insufficient power, and shaking during acceleration.
2. Higher fuel consumption: Abnormal ignition can cause insufficient combustion of the mixture, reduce conversion efficiency, and require more gas for combustion, accelerating fuel consumption.
3. In severe cases, there is also a lack of cylinder work, resulting in a series of uncomfortable jerks.
