Benefits of Spark Plugs

  • Improve performance.Spark plugs made of the chemical element iridium take less voltage to fire, providing several benefits. Iridium spark plugs allow for better combustion, lower emissions, improved fuel economy, and more horsepower.
  • Increase fuel efficiency.如果您的发动机由Worn-Out Spark插头供电,则它不会按预期一起运行。使用一组新塞子更换这些故障插头时,发动机将平稳地运行,需要更少的努力来保持燃烧过程。这将转化为长期燃料效率提高。
  • 减少排放。通过更换车辆的火花塞,减少可能发生的错误的可能性。当发生失火时,它会增加你的汽车排放。对于汽车所有者来获得利益,他们应该注意可能的火花塞麻烦的警告标志。每次更换新的插头都会出现主要问题之前,它可以最大化燃油经济性并省钱。
  • 改善加速和发动机响应。如果您的车辆行驶缓慢,需要加大油门踏板的压力,这是更换火花塞的有力迹象。当火花塞处于良好的状态或健康,他们最大限度地燃烧过程中,你的发动机,给你一个平稳和响应加速。
  • 更光滑的发动机闲置。When your spark plugs are functioning as they should, they provide adequate ignition to advance the combustion process in your vehicle’s motor. If the spark plugs are faulty, they will cause your engine to deliver a rougher than usual ride or idle. Replace older plugs with a set of new ones, and you may notice a difference in the smoothness of your car’s idle.
  • Increase fuel economy.Each time a spark plug misfires, it can reduce your vehicle’s fuel efficiency by as much as a whopping 30 percent.
  • Reduce the risk of damage to your engine and other components.Faulty spark plugs can cause misfires, poor fuel economy, lackluster acceleration, and other issues with your ignition system. Left unaddressed, malfunctioning plugs can also cause damage to other components such as your catalytic converter, so it’s vital that you immediately replace bad plugs.

火花塞类型

铜芯火花塞是最基本的和负担得起的类型的火花塞,你可以买。这些曾经是市场上最常见的火花塞类型,但由于其优越的性能、效率和寿命,最近被铂和铱火花塞取代。虽然许多现代发动机根本无法运行铜火花塞,但有一些老式发动机使用铜火花塞运行得更好。

铂金

铂金plugs deliver enhanced performance and fuel efficiency compared to copper plugs, but for a considerably cheaper price than iridium spark plugs. Much like iridium plugs, platinum spark plugs operate at a lower temperature than copper spark plugs. They can also last up to twice as long as basic copper plugs.

Double-Platinum

双铂火花塞提供比单镀铂火花塞更高的性能、效率和寿命。更重要的是,双铂火花塞仍然比铱火花塞便宜。要从单铂升级到价格合理的产品,只需寻找在电极和盖中都使用铂的火花塞即可。

Iridium

市场上最好的火花塞拥有铱星建筑。铱星插头可以为您提供比双铂塞的更好的汽油里程,性能,可靠性和寿命。由于先进的材料和创新技术集成到铱火花塞中,这些插头价格高于铜和铂选项。Iridium Spark插头非常适合在高性能发动机上使用。

Double-Iridium

双铱火花塞非常像双铂火花塞。双铱火花塞有两个由稀有金属制成的盘,以提高性能和耐久性。这些火花塞的设计是为了提供各种驾驶条件所必需的火力,包括极热或持续高速行驶。双铱的平均使用寿命是标准铜火花塞的四倍。

Spark Plug Pricing

  • Under $3:There are several spark plugs available in this value-priced range. Buyers must do their homework before purchasing cheaper spark plugs due to the vastly varying degree of quality.
  • $3-$9:大多数火花塞落入了这个定价段。大多数购物者选择此范围内的火花塞,因为它们倾向于提供理想的效率,寿命,性能和价值的融合。
  • $10 and up:在此范围内定价的火花塞倾向于采用耐用的施工,使用优质材料,先进的电极设计和无与伦比的性能,效率和长寿。

Key Features

Material

When you’re shopping for spark plugs, it’s important to consider which material best suits your needs. Copper is ideal for older model vehicles that feature a low-voltage distributor-based ignition. Platinum and iridium are best suited for modern engines without distributors. Platinum delivers a great mix of economy, performance, and longevity. Iridium offers an even better mix but at a higher cost. In the end, always use the plug specified by your vehicle’s manufacturer.

Size

指定火花塞的一个重要方法是通过螺纹或螺母的尺寸。在美国,典型的螺纹和螺母尺寸如下:10毫米(螺母:16毫米)、12毫米(螺母:14毫米、16毫米或17.5毫米)、14毫米(螺母:16毫米或20.63毫米)和18毫米(螺母:20.63毫米)。

Heat Range

A spark plug is specified as “hot” if it’s a better heat insulator, and it’s classified as “cold” if it can conduct more heat out of the tip and lower its temperature. Generally, manufacturers denote the heat range of a spark plug with a number, with some brands using ascending numbers for hotter plugs and others doing the opposite for colder spark plugs.

Gap Style

火花塞通常设计有一个火花隙,可以用火花塞间隙规工具进行调整。可以为多个发动机设计一个插头,每个发动机需要不同的间隙。汽车火花塞的间隙通常在0.6到1.8毫米(0.024到0.071英寸)之间。用间隙规测量插头间隙,确保其在规定范围内。

其他考虑因素

  • User-Friendliness.Some spark plugs come “pre-gapped” right out of the box and do not require adjustment. These pre-gapped spark plugs are convenient and ideal for consumers looking for a plug-and-play style plug that doesn’t require fussing with a gap gauge and tool during installation. If you have some experience turning a wrench, this may not be a huge deal though.

提示

  • 购买新火花塞时,请将车辆信息放在手边,以确保您购买了适合您乘坐的火花塞。车主手册或车辆登记卡应包含以下信息:车型年份、品牌、型号、发动机排量、化油器或燃油喷射类型以及气缸数。
  • 更换火花塞时更换火花塞导线是个明智的主意。有故障的火花塞会损坏导线,因此同时更换两个部件将确保您的发动机获得尽可能好的点火部件。
  • As tempting as it is, don’t always purchase the least expensive option for spark plugs. The best-quality spark plugs are usually more expensive because they guarantee optimal fuel economy, engine performance, longevity, and reliability.
  • Inspect your plugs to determine their condition. If the plugs look fine except for a red coating, this could be residual additives from poor-quality gas. Clean them off with a clean cloth and reinstall them. If the plug has black or heavy ash deposits around or on top of its center electrode, this means it must be replaced.
  • Before you remove your old plugs, clean the cylinder head around your plugs with a compressed air can or gun. This will blow away any dirt or deposits that may have collected on this area. This is important because dirt can enter the cylinder bore and score the wall and wear the rings.
  • 检查新火花塞有无损坏。确保侧电极与中心电极对齐且笔直。如果需要调整,请使用尖嘴钳轻轻地重新定位。
  • 将塞子向下放置,用化油器清洁剂喷洒中心电极周围的空腔。这是一个有效的方法,以消除任何陶瓷灰尘或碎片遗留下来的制造过程中,可能导致失火。
  • Use an anti-seize compound to coat the spark plug thread. This will make it easier to remove the plug in the future without galling the threads in the cylinder head. If any of the anti-seize compound happens to get on the electrodes, wipe it off with a clean rag moistened with carburetor cleaner.
  • 使用绝缘化合物涂覆二次接线和防尘套所在的绝缘体。绝缘化合物可防止腐蚀,并防止护套粘在绝缘体上,这可能会导致电线在将来的维护过程中断裂。
  • Never use air tools to remove or install spark plugs in your vehicle. Always thread each spark plug by hand, and then use a proper socket and wrench to tighten the plugs according to factory specifications.

FAQs

问:如何判断火花塞何时在最佳温度下工作?

如果您想知道如何在问题出现之前判断您的火花塞是否工作正常,请查看它们的颜色。通常,当火花塞是浅棕色或灰色时,应该告诉你它在最佳温度下运行。换言之,您的车辆发动机状况良好。

问:火花塞最后多长时间?

The life-span of spark plugs varies by both manufacturer and vehicle. Yet, the spark plugs in most vehicles sold on the market today should last for 100,000 or more miles. To ensure you do not go past your spark plugs interval, research the type of spark plugs to learn whether they are suitable for your vehicle. Keep in mind that the spark plugs in most performance and luxury models tend to have shorter intervals.

问:我应该多久改变我的火花塞?

这取决于您在汽车中有火花塞的质量。顶级火花塞将比较低质量的插头更长。大多数机械师建议您每30,000英里或每隔50,000英里更换铜芯火花塞,为铱芯火花塞。如果您的发动机不在最高条件下,此间隔可能会缩短,因此对您的火花塞进行过早磨损并相应地改变它们是至关重要的。

问:有故障的火花塞会打开检查发动机灯吗?

When your vehicle has a faulty spark plug, it can cause the check engine light to illuminate, signaling an issue. In some instances, the check engine light may even be flashing instead of a solid light. When the warning light appears, it is essential that you or a professional mechanic look into the cause.

问:有什么症状出现故障火花塞?

You may notice the following symptoms if your spark plugs need to be replaced: hesitation or backfiring during acceleration, decreased acceleration, rough idle, spark plug wires charred on the end that goes onto the plugs, a significant drop in fuel economy, and difficulties starting your engine. If your ride doesn’t run as well as it usually does, and you suspect it’s attributed to bad spark plugs, inspect the plugs yourself or have a mechanic do it.

问:如果你没有替换火花塞会发生什么?

为避免损坏发动机并体验驾驶问题,必须更换车辆的火花塞。随着时间的推移,火花塞将开始恶化,并且它们不会因为它们应该引发而引火,因此,没有点燃空气/燃料混合物,使燃烧过程未完成。您的车辆最终将损失发动机电源,并且在最坏的情况下,发动机将停止完全运行。

Q: Should I use hot or cold spark plugs?

在典型的驾驶环境中,您应该使用车辆制造商指定的火花塞。如果你的火花塞被积碳污染了,你的发动机空燃比很高或者烧机油,或者你经常在当地低速行驶,那么热塞可能是个不错的选择。如果你的发动机发出砰砰声,空燃比很低,或者你经常高速行驶,考虑使用冷塞。

Q: Do unopened spark plugs have a shelf life?

只要未开封的火花塞被适当地存储在干燥,凉爽的环境中,那么它们应该持续无限的时间。仅当它们暴露于腐蚀性环境因素(如水分)或者它们经常丢弃时,火花塞的寿命仅受到影响。

最后的想法

Now that you know the ins and outs of spark plugs, you can make the best decision for your vehicle. Perhaps it's our overall best pick, theNGK公司6619铱IX火花塞s, or the value of theDenso 4504 PK20TT铂金火花塞.
