摘要: Abstract Homogeneous charge compression ignition (HCCI) experiments were performed in a single-cylinder diesel engine fueled with n -heptane at constant equivalence ratio of 0.3, intake temperature 300 K, and speed 1500 rpm. The manifold was seeded by ozone produced dielectric barrier discharge reactor wire–cylinder configuration. Experimental results showed that low concentrations, i.e., -C 7 H 16  + O → C 15  + OH) the ozone-accelerated production OH up both cool main flame. O-atoms decomposition during stroke could be way to control, cycle cycle, two stage fuels HCCI engine.
