The aging and damage of ignition wires will greatly reduce the ignition energy, increase the fuel consumption of the engine, decrease the power, and seriously cause the fire break, which is a fatal fault for the engine with three-element catalytic converters.

Now, let's take a look at the maintenance and inspection of the fire line.

Many people know that spark plugs need to be replaced regularly, but they ignore the maintenance of other parts of the ignition system. The ignition high pressure line is one of them. When the engine is running, the ignition line often has tens of thousands of volts of high-voltage pulse electric current. As it works in a high-temperature, dusty and vibrating environment for a long time, aging or even damage is inevitable. Therefore, like spark plugs, it is a consumable product that needs to be replaced frequently.

The aging and damage of ignition wires will greatly reduce the ignition energy, increase the fuel consumption of the engine, decrease the power, and seriously cause the fire break, which is a fatal fault for the engine with three-element catalytic converters. According to the experience of foreign countries, even if there is no fault, every 20,000 kilometers or so of the ignition high pressure line also needs to be replaced. However, many car owners in China do not want to check the ignition system until the engine fails to operate stably or even start up. However, by this time, the fuel wasted due to the potential damage to the ignition system components and the wear and tear on the engine have far exceeded its value. In addition, the distributor cover, ignition head, ignition coil, spark plug and other components in the ignition system should also be within the scope of routine maintenance and inspection.
