Developed a first-of-its-kind zero-dimensional (0-D) internal combustion engine conceptual model based on the governing equations of thermodynamics and slider-crank mechanism. The conceptual model was translated later into MATLAB.

Reviewed detailed and reduced reaction mechanisms for diesel, biodiesel, dimethyl ether, and hydrogen and imported them into MATLAB for simulation.

0-D MATLAB model employs ode15s to solve the temporal development of important parameters and communicates with Cantera which handles combustion reaction kinetics at each iteration.

Compared 0-D model results for DME-ULSD and DME-biodiesel with experimental results.

The 0-D model predicts in-cylinder pressure, temperature, and ignition delay with reasonable accuracy. Additionally, it captures DME pre-ignition and its low-temperature kinetics.
