What are the effects of not replacing spark plugs after 220,000 kilometers?
1 Answers
The effects of not replacing spark plugs after 220,000 kilometers are that after prolonged use, the ignition efficiency of the spark plugs will continuously decline. This leads to the combustible mixture not being ignited and burned under optimal conditions, resulting in increased fuel consumption and loss of power. It can also cause difficulties in starting, engine shaking, and increased carbon deposits. Furthermore, it can damage the three-way catalytic converter and cause the exhaust emissions to fail to meet standards. Over time, this can lead to engine failure, necessitating disassembly and repair. Spark plug replacement cycle: Under normal maintenance conditions, spark plugs should be replaced after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine, so it is recommended to follow the user manual. The following standards can be used as a reference for maintenance and replacement: platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers. Steps for replacing spark plugs: Open the engine hood, lift the plastic cover of the engine, and remove the high-voltage distributor wires. Mark the position of each cylinder to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. When removing them, check for any external debris such as leaves or dust and ensure they are cleaned thoroughly. Place the new spark plugs into the spark plug holes, hand-tighten them a few turns, and then use the socket to tighten them further. Reinstall the removed high-voltage distributor wires according to the firing order, and then secure the cover.
