How Many Specifications Are There for Spark Plugs?
2 Answers
Spark plugs can be categorized into: nickel alloy spark plugs, platinum spark plugs, and iridium spark plugs. More details about spark plugs are as follows: 1. Commonly known as spark plugs. The function of a spark plug is to discharge the high-voltage pulse electricity sent by the high-voltage wire (spark plug wire), breaking down the air between the two electrodes of the spark plug to generate an electric spark, thereby igniting the mixed gas in the cylinder. 2. The spark plug works in conjunction with the ignition system and fuel supply system to make the engine perform work, collectively determining the engine's performance to a large extent. 3. They have high mechanical strength, can withstand high-temperature thermal shock and chemical corrosion, and are typically made of 95% alumina ceramic.
Having driven various cars, I've noticed there are quite a few spark plug specifications. Heat range is crucial - it's categorized by numbers indicating cooling capacity. Smaller numbers like 5 or 6 indicate slower heat dissipation, suitable for gently driven vehicles, while larger numbers like 8 or 9 with faster cooling match sports car engines. Dimensions involve thread diameter (mainstream types being 14mm or 18mm) and length must match cylinder depth. Material matters too - copper cores are cheaper but less durable, while platinum and iridium provide more stable ignition and longer lifespan. Designs vary between single-electrode and multi-electrode types affecting spark efficiency. I once tried changing spark plugs myself with wrong specifications, causing engine vibration and increased fuel consumption. Always check your vehicle manual or use matching apps - don't randomly choose for convenience. These diverse specifications exist to meet different engine requirements, and incorrect selection may cause malfunctions disrupting your trip. Spending time learning can save significant trouble.
