101905622 - Spark Plugs & Wholesale parts

The part number 101905622 refers to a specific model of spark plugs, but the detailed description depends on the manufacturer. Generally, spark plugs are essential components in an engine's ignition system. They ignite the air-fuel mixture in the engine's combustion chamber, which is crucial for the engine to operate. A spark plug typically consists of a metal threaded shell, a central electrode, and a ground electrode, creating a spark when an electrical current flows through them.

A spark plug is a crucial component in the ignition system of gasoline engines. Its main function is to introduce high-voltage electricity from the ignition coil into the combustion chamber, creating a spark between the electrodes that ignites the air-fuel mixture, thus driving the engine.

Key Components of a Spark Plug:

1. Terminal Nut: Connects to the ignition coil to transmit high-voltage electricity.
2. Insulator: Made of ceramic material with excellent insulating properties to prevent electrical leakage.
3. Metal Shell: Protects the internal structure and connects the spark plug to the engine via threads.
4. Center Electrode: Positioned at the center, it forms an arc with the ground electrode to produce the spark.
5. Ground Electrode: Located opposite the center electrode, completing the spark circuit.

How Spark Plugs Work:

The high-voltage current from the ignition coil travels through the terminal nut to the center electrode, creating an arc between the center and ground electrodes that ignites the air-fuel mixture in the combustion chamber.

Types of Spark Plugs:

• Copper Core: Good conductivity but short lifespan, typically replaced every 20,000 to 30,000 kilometers.
• Nickel Alloy: Moderate lifespan, typically replaced every 40,000 to 60,000 kilometers.
• Platinum: Longer lifespan, typically replaced every 80,000 kilometers.
• Iridium: Longest lifespan, typically replaced every 100,000 kilometers or longer.

Choosing the Right Spark Plug:

The model number of spark plugs typically includes letters and numbers that indicate their specifications. For example, the Bosch model "F7HER2BOM" can be decoded as follows:

• F: 14mm hex bolt size.
• 7: Heat range code (lower numbers indicate "cooler" plugs, suitable for high RPM).
• H: Thread length and electrode positioning.
• E: Material of the center electrode, such as nickel-y alloy for durability.
• R: Resistor type for self-cleaning.

Regular inspection and replacement of spark plugs are essential for maintaining engine performance and fuel efficiency.
