    abstract = {This study presents a detailed mathematical modeling and simulation study of CNG-diesel dual fuel
compression ignition engine cycle processes using EES (Engineering Equation Solver) software. By means of
a step-by-step simulation approach, the values of pressure, volume and temperature at all the state points in
the ideal, air-diesel and CNG-diesel dual fuel cycles are computed. Various performance parameters such as
thermal efficiency, power output, mean effective pressure and network output are evaluated for chemically
correct (Y = Y<sub><em>cc</em></sub> ) air fuel mixtures assuming adiabatic combustion and full load operation for diesel and CC
CNG-diesel fuel modes. CNG available in National Capital Territory of Delhi has chemical composition with
methane content of 84.5% on Mole basis. In this study, the impact of other two main constituents of CNG, i.e.,
Ethane (C<sub>2</sub>H<sub>6</sub> ) and Propane (C<sub>3</sub>H<sub>8</sub> ) on the CNG-diesel dual fuel engine parameters is also analyzed. The predicted 2 6 3 8
results of various performance parameters of dual fuel cycle using 15% diesel fuel and 85% CNG fuel with 100%
methane (CH<sub>4</sub>) in it and with 84.5% methane, 12.5% ethane and 3% propane are computed and presented 4
graphically. Predicted results of cycle simulation indicate that conversion of diesel to CNG-diesel is possible
with no change in compression ratio, engine design and engine basic structure.}
