Q1: How long can a car spark plug be used?

A: The lifespan of a car spark plug does not have a fixed time, and its lifespan mainly depends on the following factors:

1. Quality: The quality of the spark plug directly affects its lifespan. Spark plugs with better quality are usually more durable and can be used for a longer period of time.

2. Driving conditions: Under harsh driving conditions such as prolonged low-speed driving, urban congested roads, frequent start-stop situations, etc., the lifespan of spark plugs may be relatively shorter.

3. Engine condition: The condition of the engine directly affects the lifespan of the spark plug. For example, the state of the engine fuel mixture, the operation of the ignition system, etc., can all have an impact on the spark plug.

 

In general, under normal use, spark plugs can be used for around 20,000 to 30,000 kilometers. However, it is recommended to regularly inspect and replace spark plugs to maintain the engine's optimal performance and fuel economy. The specific replacement interval can be referred to the recommendations of the automobile manufacturer or the maintenance manual.

 

Q2: What are the symptoms of a bad spark plug in a car?

A: Possible symptoms of a faulty spark plug in a car are:

1. Engine fails to start or starts with difficulty: The spark plug is part of the ignition system, and if it is damaged, the engine may fail to ignite properly, resulting in difficulty or inability to start.

2. Engine vibration or shaking: A damaged spark plug may not provide a stable electrical spark, causing the engine to vibrate or shake, particularly at idle or low speeds.

3. Rough acceleration or loss of power: A malfunctioning spark plug may not provide enough energy to ignite the air-fuel mixture, resulting in rough acceleration or loss of power in the engine.

4. Increased fuel consumption: A damaged spark plug can cause a decrease in combustion efficiency, leading to wasted fuel, and consequently, increased fuel consumption.

5. Unusual noise during engine start-up: A faulty spark plug may result in abnormal noises during engine start-up, such as popping or snapping sounds.

 

If any of these symptoms occur, it is recommended to promptly visit a professional auto repair shop for inspection and replacement of the spark plug.
