Study On Ignition With Pulse Resonance Electric Arc And Microwave Discharge

In recent years,with the improvement of people's living standards,the proportion of automobiles in household expenditure has increased year by year.However,while providing travel convenience,the pollution brought about by automobiles still cannot be ignored.Automobile exhaust is one of the important factors that giving rise to the pollution of city,city pollution is mainly derived from the exhaust emission of fuel vehicles.In the hustled and bustled urban life,it is the problem which people should think about and solve.This paper mainly uses the pulse microwave resonant arc discharge ignition combustion device to improve the automobile and other motor vehicle ignition device,compared to the traditional spark plug ignition,the plasma of microwave ignition has a large volume and it can burn rapidly,complete burn the mixed gas.All in all,it has improved the combustion efficiency and reduced exhaust emissions.In order to obtain a stable low temperature microwave discharge plasma under the advantage of atmospheric pressure and applying it in the field of automotive engine ignition,the design of a pulsed resonant micro glass arc discharge ignition combustion device in this paper,the device comprises a slander vibration high frequency and high voltage power and microwave discharge device.A slander vibration high frequency and high voltage power control spark discharge.Spark discharge benefit phantom discharge and microwave field.As the experiment shows,the square wave signal pulse driving solid-state high-frequency switch with high frequency,single spark can realize controllable pulse spark ignited in the combustion zone with high frequency and high voltage and the microwave phantom discharge,simultaneously ignite the fuel;fuel availability has been greatly improved and exhaust emissions has been widely reduced by using microwave discharge.By analyzing the experimental results and phenomena,it can be concluded that the ideal microwave discharge ignition can be obtained under given square wave signal and microwave power.
