The spark plug is usually replaced once at 30,000 km. The Honda Fit has a total of eight spark plugs, using the DSI intelligent dual ignition system, with two spark plugs per cylinder. The ignition system of a gasoline engine introduces a high voltage current into the cylinder to generate an electric spark to ignite the components of the combustible gas mixture. It is mainly composed of a wiring nut, an insulator, a wiring screw, a center electrode, a side electrode and a shell, and the side electrode is welded on the shell. In the standard of spark plug, the heat value of spark plug is commonly used to characterize the thermal characteristics of spark plug, spark plug heat value indicates the balance ability of heat absorption and heat dissipation of spark plug insulator skirt, the higher the heat value. The balance between heat absorption and heat dissipation is stronger, so the heat value of the hot type spark plug is low, and the heat value of the cold type spark plug is high. Generally, the engine with high power and high compression ratio uses the cold type spark plug with high calorific value; On the contrary, the engine with low power and small compression ratio uses the hot type spark plug with low calorific value. The selection of the general spark plug is determined by the factory through the product styling experiment, and should not be replaced at will.
Fit spark plug in the use of two years or about 30,000 kilometers to replace once, the spark plug is a motor vehicle vulnerable parts, not within the scope of warranty, spark plug damage need to be replaced in time, damage caused by the fault is difficult to start the engine, or a lack of cylinder after starting. The spark plug used by the engine is very important to the engine, the spark in the event of a problem, the motor vehicle will not be able to start normally, after barely starting, the engine will shake. Affecting the normal use, will lead to insufficient engine power, increased vehicle fuel consumption, increased noise, strengthen the internal wear of the engine, resulting in engine failure.
