- Sugarcane off-season and increased demand raise fuel prices
- Company explains how maintenance can minimize gasoline and ethanol costs
- Oxygen sensor and improperly functioning spark plugs can cause increased consumption and damage other components.

das 27 capitais brasileiras, according to research by the National Petroleum Agency (ANP). A NGK, largest manufacturer and specialist in spark plugs and cables in the world, remember that a correct maintenance on the spark plugs, ignition cables and other components, like the oxygen sensor, can help in fuel economy and minimize the effects of constant variations in the values of ethanol and gasoline. Among the items that deserve more attention, the spark plug plays a fundamental role in consumption. The part is responsible for ensuring that all fuel is burned, without resulting in waste. Irregular spark plug operation, which is often caused by component wear, is not clearly perceptible to the vehicle owner. This situation, although, directly affects fuel consumption and causes increased levels of pollutant gas emissions. That is why, NGK reiterates the importance of a periodic review, as these distortions in vehicle performance are only identified later, when the driver sees starting difficulties and failures during restarts. Mostly, when the problem starts to be noticed, it is a sign that the fault has been occurring for some time, may cause more serious damage to other components as well.. The use of excessively worn spark plugs can compromise the ignition cables., lambda sensors, rotor, distributor and coil/transformer. NGK recommends that candles be checked every 10.000 km or annually, what comes first.
Sonda lambda the oxygen sensor, also known as a lambda probe and marketed under the NTK brand., is responsible for analyzing the condition of the fuel combustion, being essential in the control of pollutant emission and consumption. The part compares the concentration of oxygen in the engine gases with the ambient air, enabling the adjustment of the amount of fuel injected into the combustion chamber. This optimal adjustment of the amount of fuel injected into the combustion chamber promotes the best performance ratio., consumption and emissions. Furthermore, the erratically working probe can accelerate the deterioration of other parts, like the catalyst.
ignition cable The ignition cables, responsible for conducting the high voltage produced by the coil (transformer) even the candles, without allowing current leakage, also need periodic checking, which must be performed every 60.000 kilometers or three years.
