New OEM Replacement Iridium Auto Spark Plug DCPR7E With 80000km Warranty And 4pcs/Box

Description :

A spark plug is an essential component of the ignition system in most internal combustion engines. It is responsible for generating the electrical spark required to ignite the air-fuel mixture in the engine's combustion chamber. The spark plug is typically located at the top of each cylinder in the engine's cylinder head.

The basic structure of a spark plug consists of a metal shell, an insulator, a central electrode, and a ground electrode. The metal shell is threaded and screwed into the engine's cylinder head, providing a secure connection. The insulator, made of ceramic or other non-conductive materials, surrounds the central electrode and provides electrical insulation. The central electrode extends into the combustion chamber and is connected to the ignition system, while the ground electrode is located at the base of the plug.

During the engine's operation, high voltage electricity is delivered to the spark plug by the ignition system. The voltage jumps across the small gap between the central and ground electrodes, creating a spark. This spark ignites the compressed air-fuel mixture in the combustion chamber, initiating the combustion process and generating power to drive the engine.

Spark plugs are crucial for efficient and reliable engine performance. They need to be properly maintained and periodically replaced to ensure optimal ignition and combustion. Different engines may require specific types of spark plugs, depending on factors such as the engine's design, fuel type, and performance requirements.

What do spark plug do?
 

Spark plugs are designed to meet the different requirements of engine configurations and performance. Conventional spark plugs are generally suitable for standard engines, which consist of a solid ceramic insulator that surrounds the central electrode. Resistor spark plugs, on the other hand, possess a resistor in their body or ceramic insulator which helps reduce electromagnetic interference with electronic components in the vehicle. The spark gap of spark plugs, which refers to the distance between the central electrode and the ground electrode, can affect engine performance, fuel economy, and emissions, so it is necessary for vehicle owners to set and maintain the correct gap specified by the vehicle manufacturer.

Over time, spark plugs may accumulate deposits which results in fouling. This can be due to oil leakage, incomplete combustion, or the use of improper fuel. Fouling can be identified as carbon deposits, oil deposits, or fuel deposits. It is necessary to inspect and clean or replace fouled spark plugs in order to maintain optimal engine performance.

In some ignition systems, spark plugs will be connected to the ignition coil or distributor through spark plug wires; these transmit the high voltage electrical charge to the plugs. It is crucial to check the condition of spark plug wires, as damaged or deteriorated wires can result in weak or inconsistent sparks. For high-performance engines or specialized applications, performance spark plugs are available and they are designed to withstand higher temperatures and provide more reliable ignition performance.

Finally, it is important to note that spark plugs require regular maintenance and replacement. Depending on the type of spark plug, driving conditions, and maintenance practices, the replacement interval may vary. Regular maintenance of spark plugs, including cleaning or replacement, will ensure optimal engine performance and reliability.
