Abstract
The characteristics of a microwave-enhanced laser ignition of methane/air lean premixed mixture in the constant volume combustion vessel is experimentally investigated. The microwave-enhanced plasma is applied as an advanced ignition source due to the controllability of the plasma life time. The parameters of the microwave are varied for elucidating the effects of microwave-enhancement on laser ignition. Results shows that the microwave-enhanced laser ignition decrease the total time of combustion. This is because the large volume and long life time plasma decrease the time of initial development of the ignition kernel. In addition, the total energy of microwave enhanced laser ignition can be reduced effectively by applying the duty ratio of microwave.
