Ignition Process:
1. Main combustion chamber will be filledwith lean mixture of natural gas and air
2. Prechamber will be flushed with natural gas(rich mixture within prechamber)
3. Compression by upward piston motion (checkvalve prevents gas losses)
4. Spark plug initiates the ignitionwithin prechamber
5. Flames coming out of the prechamber start combustion within main combustion chamber
