How do Industry Spark Plugs work in internal combustion engines?

1. Ignition of mixed gas

Introduction of High Voltage Electricity Industry Spark Plugs receives high-voltage electricity from the ignition coil through high-voltage wires. These high voltage electricity are introduced into the gap between the center electrode and the side electrode of the spark plug.
Electric spark generation: When the voltage between the electrodes reaches a certain value, the air in the gap of the spark plug will be ionized to form a discharge channel. At this time, the gas forms a luminous body, that is, a "spark", which is enough to ignite the mixed gas.
Mixed gas combustion: The ignited mixed gas expands rapidly to produce high-temperature and high-pressure combustion gas. These combustion gases push the piston downward to output power.

2. Key components and structures

Center electrode and side electrode: A discharge gap is formed between the center electrode and the side electrode of the spark plug, which is the key part for generating electric sparks.
Insulator: The insulator is used to isolate the center electrode and the side electrode to prevent current leakage.
Casing: The casing of the spark plug is usually used to fix and support other components and play a role in heat dissipation.

3. Action process and cycle

Intake process: In the working cycle of the internal combustion engine, the intake process is carried out first. At this time, the piston moves downward, the intake valve opens, and the fuel/air mixture enters the cylinder.
Compression process: After the intake valve is closed, the piston moves upward to compress the intake gas, increasing its temperature and pressure.
Ignition process: When the piston reaches the highest point, the Industry Spark Plugs is triggered, generating an electric spark to ignite the mixed gas.
Exhaust process: The exhaust gas after combustion is discharged from the cylinder through the exhaust valve, completing a working cycle.

4. Performance and impact

Ignition performance: The ignition performance of Industry Spark Plugs directly affects the combustion efficiency and power output of the internal combustion engine. High-quality spark plugs can ensure that the mixed gas is ignited quickly and reliably.
Service life: The service life of the spark plug is affected by many factors, including the working environment, fuel quality, ignition times, etc. Regular inspection and replacement of spark plugs is one of the important measures to maintain the performance of the internal combustion engine.
