選哪種火星塞來用比較好???
市面上有廠商、車行大力在推荐 "不需要變更車上的點火線組, 直接換火星塞即可明顯提升引擎效能" 的方案, 但是... 真的有效嗎?? ;-)有電阻火星塞 vs 無電阻火星塞 |
無電阻火星塞
只換(無電阻)火星塞真的可以有效、明顯提升引擎效能?無電阻火星塞產生的火花並無明顯較強烈
無電阻火星塞並沒有提供明顯的跳火差異, 但是卻
下圖即為火星塞大廠 - NGK 針對有電阻(藍色曲線)、無電阻(灰色曲線)的火星塞製作的雜訊/電磁波曲線圖; 從曲線圖可以明顯看到無電阻火星塞(灰色曲線)的 EMI 較有電阻火星塞(藍色曲線)大了近 2 倍之多!

EMI 干擾
電子產品很容易受到 EMI 干擾而導致發生 "誤動作" 甚至停擺的情況, 也因此火星塞製造廠會強烈建議採用有電阻的火星塞, 避免車輛受到 EMI 干擾而引起問題.除了火星塞有區分有、無電阻之外, 高壓線(所謂的矽導線) & 火星塞帽也分有電阻與無電阻兩種款式; 把這 3 項零件全部換成無電阻的款式,
文章最後還是建議各位朋友使用 "有電阻的火星塞、火星塞帽、高壓線", 這是最安全、保險又實際的作法. :-)
註1: NGK 官方網站有提到 "火星塞不管有沒有電阻, 對於車輛的油耗、馬力、加速等效能表現皆無任何影響(As the resistor spark plug has an incorporated resistor, some people think that it has adverse effects on start-up, acceleration, fuel economy and emissions. However, this is wrong. It does not affect engine performance so don't hesitate to use it. <link>)"

註2:
from NGK:
WHEN SHOULD I USE A RESISTOR SPARK PLUG?
A: NGK "R" or resistor spark plugs use a 5k ohm ceramic resistor in the spark plug to suppress ignition noise generated during sparking.
NGK strongly recommends using resistor spark plugs in any vehicle that uses on-board computer systems to monitor or control engine performance. This is because resistor spark plugs reduce electromagnetic interference with on-board electronics.
They are also recommended on any vehicle that has other on-board electronic systems such as engine-management computers, two-way radios, GPS systems, depth finders or whenever recommended by the manufacturer.
In fact, using a non-resistor plug in certain applications can actually cause the engine to suffer undesirable side effects such as an erratic idle, high-rpm misfire, engine run-on, power drop off at certain rpm levels and abnormal combustion.
