Prechamber Spark Plug

 In generator sets, prechamber spark plug is typically used in gas engines (such as natural gas or biogas generator sets). Its function is to ignite the mixture in the prechamber and then ignite the mixture in the main combustion chamber through flame injection, thereby improving combustion efficiency and reducing emissions. The following is a detailed description of prechamber spark plug in the pre-ignition chamber and key points for maintenance.

Ignition control: Sparks are generated in the pre-combustion chamber, igniting the mixture in the pre-combustion chamber to form a high-temperature and high-pressure flame, which is then sprayed into the main combustion chamber through the spray holes to ensure stable combustion.

Optimized combustion: Enhance Lean Burn performance, increase thermal efficiency and reduce NOx emissions.

Adaptable to multiple fuels: Suitable for gaseous fuels such as natural gas, biogas, and hydrogen.
