Spark plug S-R6A19

Pre-Chamber Spark Plug

A pre-chamber spark plug is designed for use in an engine’s pre-combustion (pre-chamber) system, where ignition takes place in a small chamber before the flame spreads into the main combustion chamber. This design improves combustion efficiency, stability, and overall engine performance, especially in high-pressure gas engines.

How It Works

• The spark plug ignites the air-fuel mixture inside the pre-chamber.

• The energy release is distributed through multiple small jets into the main combustion chamber.

• This creates a more controlled and efficient combustion process.

Key Features

• Improved ignition control through pre-chamber combustion

• Better fuel concentration at the spark gap for efficient ignition

• Lower electrode temperature during operation

• Reduced electrode wear and erosion

• Longer service life compared to conventional spark plugs

• Lower required operating voltage in high-pressure engines

• High resistance to misfires and short circuits

• Reliable performance even in humid or moist conditions

Advantages

• Enhanced combustion stability and efficiency

• Increased engine safety and reliability

• Reduced maintenance and replacement frequency

• Improved performance in lean-burn gas engines

• Lower emissions due to more complete combustion

Applications

• Industrial gas engines

• Power generation systems

• Combined Heat and Power (CHP) plants

• Biogas and landfill gas engines

• High-pressure stationary engine applications

Pre-chamber spark plugs are widely used in modern gas engines due to their superior combustion control, durability, and reliable performance under demanding operating conditions.
