Microwave-assisted spark plug ignition method and microwave-assisted spark plug ignition integrated set

2016 
The invention discloses a microwave-assisted spark plug ignition method, comprising the steps of issuing a pulse signal to a spark plug system to trigger the same to generate a pulse high voltage; issuing a pulse signal to a microwave system to trigger the same to generate a microwave pulse of specific frequency and power; loading the pulse high voltage to a spark plug, breaking down thin gas via arc discharging to generate a plasma cluster; the plasma cluster can be expanded via microwave pulse irradiation to achieve ignition via thin combustion in an internal combustion engine. The invention also discloses a microwave-assisted spark plug ignition integrated set. The method of the invention combines the advantages of spark plug high-voltage discharge breakdown and those of microwave-to-plasma-cluster coupling energy; the integrated set of the invention includes a spark plug system and a microwave system, and achieves stable ignition via thin combustion in high-pressure environment of a combustor of the internal combustion engine.
