| Abstract: | The pilot diesel fuel ignition model and the dual fuel engine com bustion model are reconstructed. Based on the models, a theoretical study on the characteristics of atomization, evaporation and ignition of the pilot diesel fu el and their effects on combustion process is carried out under different stoich iometric mixture ratios. And the injection characteristics of pilot diesel fuel for realizing quasi-homogenous charge compression ignition (QHCCI) of pre-mixe d natural gas are given. |
