2,5-Dimethyl Furan (DMF) direct injection in compression ignition engine simulation and experimental research article focused on selecting one of the three swirl ratio piston bowls that predicted low ignition delay and was compared to the other two chosen bowls for better combustion. A pump capable of pumping 400 to 1200 bar pressure was set and used for the injection pressure. With a constant compression ratio of 18.54:1, and selected three different swirl ratio piston bowls with the appropriate parameters for comparison. Predicted low ignition delay for an MDF high compression direct injection (HCDI) engine by selecting three different swirl ratio piston bowls. CA, HRR with CA and SFC, NOx, ID, and PM emissions werwere e predicted and compared with variable injection pressure in the in-cylinder pressure (ICP). Low ignition delay is achieved by selecting one of three combustion chambers based on EGR mode (with or without), which ranging % to 15%. Testing confirmed that the performance of a chosen combustion chamber bowl (A) was better than the other two chambers.
