Abstract: A computational study is conducted for a DME fuelled CI engine of 373.3 cm3 displacement and 17.8 compression ratio at moderate load with detailed chemistry. Due to the symmetry of the cylinder, the simulations are conducted on a sector of the cylinder, from the closing of intake valve to the opening of exhaust valve. In the pilot injection strategy employed, 10% of the total fuel is injected during the pilot injection and the balance in the main injection at 50 BTDC. The computational model is first validated using the experimental data. Results show two-stage ignition characteristic for the DME injected in the pilot injection.
