The detailed flow, combustion process and emissions are studied within a In-Direct Injection (IDI) type diesel engine fueled with isooctane using a three-dimensional CFD code known as integrated CKL (CHEMKIN-KIVA-LES) solver that has been successfully developed by the authors to capture the details of turbulence flow structures and chemical kinetics. This CKL solver features three-dimensional turbulent two-phase flow and combustion with one equation k-Δ Large Eddy Simulation (LES) model for turbulence and CHEMKIN for chemical kinetics. The CKL solver was validated using the experimental data from modified KUBOTA D905 IDI type diesel engine converted to HCCI engine. Then the CKL solver is employed to study the effect of fuel injection strategies on the HCCI engine combustion process.
