Iridium And Platinum Plug

A spark plug is used for transmitting electrical current from an ignition system to a spark-ignition engine combustion chamber to ignite the compressed fuel/air mixture with an electrical spark, thus maintaining combustion pressure inside the engine. Spark plug has the middle and side electrode made with precious and other metals. The metal channels the high voltage from the spark plug wire into the spark plug so that it can flame through the small gap between the main electrode and the side electrode while exiting. This is the critical spark from which the cycle of combustion begins. Platinum is metal much stronger than nickel alloy and has a higher melting point. A single platinum plug is much like a copper spark plug with a platinum disc welded to the center electrode, a double platinum spark plug has a platinum disc on both center and side electrodes Platinum is much harder metal, which has a higher melting point. This keeps the sharp edge even longer than a traditional spark plug, up to 100,000 miles, because platinum is harder. Longevity is an significant advantage of platinum spark plugs. Another advantage of platinum spark plugs is that they are running a little hotter, which better burns contaminants off the spark plug and helps prevent fouling. Platinum also manages high heat, which allows a better wear of the spark plug. Iridium spark plugs feature a fine wire center electrode designed to better conduct electrical energy and increase efficiency in the firing process. This precious metal is high priced. Usually Iridium spark plugs are the most costly spark plug. Acceleration is improved when you turn to Iridium spark plugs. The throttle operation has a fast response and you can feel the difference compared to the original plug. Iridium spark plugs boost the performance of the engine as regards fuel. In conditions such as climbing hills, the extra power is evident, giving you a relaxed driving and touring experience. An Iridium spark plug's ultra-fine centre electrode ensures a fast ignition and improves the starting characteristics of the engine. These plugs deliver economic as well as environmental benefits. Iridium spark plugs boost the performance of the engine as regards fuel. The idling is smooth, and fuel economy is improved. Since Iridium spark plugs guarantee excellent ignition, the fuel is efficiently burned.

If you want to use the longest-lasting spark plugs in your vehicle then you will want to use iridium spark plugs. Iridium spark plugs are estimated to last for at least 40,000 miles but were known to go up to 60,000 miles or even 80,000 miles. Iridium is a silvery-white metal which is more difficult than platinum. This makes it the most demanding spark plug on the market. The iridium spark plug therefore has the greatest longevity and helps you to get the best out of it that is possible. Many of the features on a platinum spark plug look similar to those on a copper spark plug. A copper spark plug however contains an electrode of the nickel alloy centre while a platinum spark plug has an electrode of the centre of the platinum. Therefore platinum spark plugs can last up to 60,000 miles while a copper spark plug can last up to 20,000 miles. Platinum tends to hot much quicker than other materials. This is also a bonus to a platinum spark plug because it ensures the debris is burned up that gets on the plug. You have a smooth running electronic distributor ignition system, whenever you have less debris.

Electric current flows from the battery to the induction coil which increases the voltage to ignite the plugs. You need Spark Plugs to produce a smooth burn. Each spark plug is connected to an ignition device. Once the coil produces high voltage, electrical impulses travel through insulated plug wires from the ignition coil. Spark plugs allow voltage from a lower voltage battery in excess of 20,000 Volts. When the voltage reaches the dielectric strength of the gases, a spark jumps the gap at the firing end of the tube, and the mixture of air and fuel is ignited.

Spark plugs are attached to the cylinder head of the engine.
