| Abstract(E) | The fundamental combustion characteristics of diesel methanol co-combustion were investigated over a wide range of conditions by the visualization experiments using a rapid compression and expansion machine. In addition, a reaction mechanism was selected based on the analysis of ignition delay and the laminar flame speed by detailed chemical kinetic calculation, and a highly accurate 3D-CFD model capable of predicting combustion under various parameter changes was developed. It was found that that excessively advanced or retarded diesel injection timing result in the deterioration of the diesel spray behavior and causes a significant ignition delay. |
