heavy traffic, which has become common in the daily lives of big cities, can be harmful to the vehicle, especially for components that wear out regardless of mileage driven, like spark plugs. According to NGK, reference company in ignition system, this is because, even though the car is stopped in the traffic jam, the engine continues to run and in unsuitable conditions, such as low rotation and low temperature in the combustion chamber. "Oftentimes, the driver is only based on the mileage to carry out the reviews, what is not correct. in heavy traffic, the mileage is not changed, but the components keep working under severe conditions", explains Hiromori Mori, NGK Technical Assistance Consultant. The automakers themselves recommend that vehicles that frequently face congestion should anticipate the maintenance plan by half. "If the owner's manual directs the inspection of the candles every 20.000 kilometers, They should be analyzed by a specialist after 10.000 kilometers", complete. Deteriorated sails can cause problems such as difficulty starting, excessive fuel consumption, failures during speed resumptions and increased levels of pollutant emissions. That is why, It is essential to periodically review the ignition components.. "Due to technological evolution, the engines are conditioned to work in adverse situations, which prevents the driver from noticing the fault at first. Thus, when the owner identifies the problem, it's been going on for some time.. In addition to the increase in fuel consumption, this may have harmed other important components", affirms Mori. Visual check identifies serious problems during review, the qualified professional is able to identify problems by checking the appearance of the candles, which can signal engine failures as excess fuel, infiltration of oil and coolant into the combustion chamber and use of poor quality gasoline or ethanol. It is also important to carry out a visual check of the entire ignition system, including cables and coils. Thus, it will be possible to identify cracks and cracks in the coil body and oxidation in the high voltage towers and terminals, in addition to detecting cuts, oxidation and degradation of terminals in ignition cables. Preventive maintenance, helps prevent serious engine failures, in addition to having a lower repair value for the vehicle owner. The NGK specialist warns that, postpone periodic maintenance, in addition to the risk of damaging other components, raises maintenance cost and increases fuel consumption, which represents a high cost that, often, is not accounted for by the vehicle owner. That is, periodic revisions generate savings and ensure vehicle availability when you need it..
