Heavy traffic can intensify component wear

With the end of school holidays, and NGK, largest manufacturer and specialist in spark plugs in the world, warns about the wear of various vehicle components, caused by congested traffic in large urban centers. Even though the car remains stopped, the engine continues to run and, thereby, The indication of mileage traveled on the odometer is not an accurate reference for exchanging some items, like spark plugs.

The vehicle Owner's Manual, for the most part, presents a maintenance plan with the recommended mileage for changing spark plugs. Automakers recommend in the manual that, in case of vehicles excessively exposed to congestion, This plan should be cut in half. NGK advises that spark plugs be removed every 10,000 kilometers for a visual inspection. The need to exchange the item can be confirmed by visually inspecting the electrodes, carried out by a trusted professional.

Lack of preventive maintenance on these components can cause misfires., causing defects such as difficulty starting the vehicle, high fuel consumption, irregularities in functioning, failures during resumptions and increased levels of pollutant emissions. Often, These problems are not noticed by the vehicle user. When they start to get noticed, This is a sign that the failure has been occurring for some time., which may cause more serious damage.

A new candle has sharp corners that give the effect of points, increasing the ignition (ease of jumping the spark of the candle). with wear, There is a rounding of these electrodes, providing its clearance and consequent increase in the voltage necessary for the spark to occur, which can harm various components of the ignition system, like the rotor, distributor cap, ignition cables and even in the transformer (ignition coil).

“Visual analysis of spark plugs will be an important source of diagnosis. Through your appearance, 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", reinforces Hiromori Mori, NGK Technical Assistance technician. The company provides a diagnostic poster that guides the repairman in the assessment. This poster can be requested, free, through SAC 0800 197112.

NGK do Brasil also offers the market its application table, where the mechanic can consult the correct installation of the spark plug, according to the characteristics of the vehicle in the workshop. The 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. It is recommended that the replacement of the cables be carried out every 60 thousand kilometers or every three years. For cars that use CNG (Vehicular natural gas), as well as for vehicles used in severe conditions, such as heavy traffic, revisions should be made every 30,000 kilometers.
