Afterburner systems, designed to operate up to a stoichiometric overall mixturestrength , are always fairly close to combustion instability or screech.
The stronger air motions are helpful in organizing mixturestrength distribution and then realizing lean mixture combustion in two-valve gasoline engines.
强化空气运动的结果有利于组织燃料在缸内的浓度分布,从而为在二气门汽油机上实现稀薄燃烧打下基础;

To analyze the features of the large-size asphalt mixture and the mechanism of strength formation and make a research on the gradation design of it.
