A NGK, largest manufacturer and specialist in spark plugs in the world, makes an important warning to drivers: various vehicle components wear out in slow or congested traffic, although the vehicle remains stationary the engine continues to run. In this case, only the indication of mileage traveled is not an accurate reference for exchanging some items, like spark plugs. NGK recommends that for vehicles used in heavy traffic, the maintenance plan indicated by the manufacturer be cut in half. That is,
se montadora recomenda a troca das velas a cada 20.000 kilometers,
as mesmas devem ser substituídas a cada 10.000 kilometers when it is a vehicle excessively exposed to traffic jams. The need to change the spark plugs can be confirmed after a visual inspection of the electrodes by a trusted professional. Some common defects in vehicles are caused by misfires, among them can stand out: difficulty in starting the vehicle, high fuel consumption, irregularities in functioning, failures during resumptions and increased levels of pollutant emissions. These failures are often not noticed by the vehicle user. When he starts to notice the failures, it is a sign that the failure has been happening for some time, may cause damage to other vehicle components. A new sail has sharp corners that provide a spiked effect., increasing the ignition (ease of jumping the spark of the candle). with wear, there is a rounding of these electrodes, increasing your slack. This causes an increase in the tension necessary for the spark to occur, which can damage various components of the ignition system such as rotor, distributor cap, ignition cables and even in the transformer (ignition coil). An important advantage of removing the spark plugs for inspection is that through visual analysis the professional can obtain a lot of information about the internal conditions of the combustion chamber.. NGK do Brasil provides a diagnostic poster that guides the repairman in the visual analysis. This poster can be requested free of charge through your SAC 0800 197112. According to Hiromori Mori, NGK Technical Assistance technician, candles are an important source of diagnosis.. "This because, through its aspect, it is possible to identify several problems arising from the engine. For this reason, we recommend that it be checked periodically by a trusted professional", Mori reiterates. NGK do Brasil makes its application table available to the market, where the mechanic can consult the correct application of the spark plug through the characteristics of the vehicle in the workshop. The NGK application table can be downloaded from the website
www.ngkntk.com.br or requested in the SAC.
Ignition Cables The function of the ignition cables is to conduct the high voltage produced by the coil to the spark plugs, without allowing current leakage.
Recomenda-se que a substituição dos cabos seja realizada a cada 60 mil quilômetros ou a cada três anos.
Para automóveis que utilizam GNV – Gás Natural Veicular – as revisões devem ser feitas a cada 30 mil quilômetros. For more information, NGK do Brasil provides the email:
