Iridium spark plugs have the ignition efficiency of microscopic electrodes
Ignition performance of microscopic electrodes
Quentin activity of the electrodes.
The operation of electrodes, at low temperatures, in absorbing energy for the development of the flame core immediately after the spark is formed is called extinguishing action.
Why are the ignition characteristics of Iridium IX plug spark plugs so good?
| Iridium IX |  |
Since the tip of the electrode has been given a small surface area, the Iridium IX plug has a small cooling (cooling) effect and the flame can grow wide. |
|
|
The electrodes have a small surface area and a small amount of absorbed heat. |
|||
| Nickel | |
When the plug electrode temperature is low (when starting the engine, when idling, at low speeds, etc.), if the area (volume) of the electrodes is large, since being in a Nickel-type plug, energy is absorbed due to the low electrode temperature and the development of the flame is hindered. |
|
|
Heat is absorbed by both the central electrode and the earth electrode |
|||
| Iridium IX | |
On Iridium IX spark plugs, the tip of the electrode forms an acute angle, so there is little dispersion at the site where the discharge occurred, and the discharge is concentrated at the end. This means that the flame grows quickly unhindered and the ignition performance is improved. |
|
|
The discharge occurs at the end of the electrode so there is little dispersion. |
|||
| Nickel | |
In the case of Nikel spark plugs, the discharge site may be scattered. For example, if the discharge takes place in position (1) as indicated in the photo on the left, the ground electrode hinders the growth of the flame, and the combustion process becomes unstable. |
|
|
The discharge occurs at a location where the flame is difficult to grow. |

Manufacturers have solved this problem by using a preheating system to assist in increasing the required initial temperature in diesel or some other non-sparking engines.
NGK spark plugs guide to use NGK spark plug codes corresponding to popular cars in Vietnam market
At the beginning of 2021, NGK Spark Plugs have updated the instruction sheet for using NGK spark plug codes for popular motorcycles in the Vietnamese market, in order to help customers, partners and car mechanics quickly find the right type. products according to your needs.
The Iridium NGK Laser spark plug features a microscopic central electrode head design with a layer of precious metal code on the contact electrode surface, which increases maximum performance and life, increases ignition, acceleration and is more fuel efficient with conventional spark plugs or platinum spark plugs.
Diesel engines work by compressing the fuel mixture under such great pressure that it ignites automatically. By not using sparks, diesel engines need a large compression ratio to push the temperature up. This ratio sometimes reaches 20:1 while the average gasoline engine only needs 9.5:1.
A spark plug must release some of the heat generated by the combustible gas. The heat index is the parameter that indicates the amount of heat released.
When used for a long time, it will often experience some conditions such as soot, overheating,... These phenomena make the car difficult to operate and quickly fail the engine.
As we all know, spark plugs are products that need to be replaced every year. What's more, it's a small but important part that's integral to every person's motor vehicle.
