How many kilometers should the spark plugs of the Lingpai car be replaced?
1 Answers
The spark plugs of the Lingpai should be replaced every 60,000 kilometers. Methods to determine if the spark plugs are damaged: Remove the spark plugs and observe them. Based on the following appearance colors, judge the condition of the spark plugs. Normal spark plugs have a skirt and electrodes that appear gray-white, gray-yellow, or light brown. A properly functioning spark plug has a skirt that is reddish-brown, with an electrode gap between 0.8-0.9mm and no signs of electrode burn. If the spark plugs are oily or have deposits, but the spark plugs themselves are not damaged, they can continue to be used after cleaning off the oil and deposits. If the spark plugs are severely damaged, with signs such as blistering at the top, black streaks, cracks, or melted electrodes, the cause of the damage should be identified. After troubleshooting, replace the spark plugs with new ones. Additionally, if the spark plugs appear black as if smoked, it indicates that the wrong type of spark plug (too cold or too hot) was selected, the air-fuel mixture is too rich, or engine oil is leaking into the combustion chamber.
