Abstract:
Dual Fuel Combustion is a feasible approach to control engine combustions, especially in diesel engines. The use of natural gas in dual-fuel combustion is envisaged due to its abundance in the environment, low C/H ratio, and low soot producing tendency. It is also used due to its low price and clean-burning characteristics relative to diesel fuel. The process of Dual Fuel combustion also reduces the number of harmful emissions such as CO, NOx, and Soot and their impact on the environment. In this study, the combustion process of Diesel Engine was studied. The addition of methane CH4 was simulated using numerical techniques of Ansys Forte 2019. The experimental data was validated using Accumulated Chemical Heat Release Rate (ACHRR), and it was observed that the numerical results were quite close to experimental results. A parametric study was also performed to study the effect of different intake parameters on the production of harmful exhaust emissions. The production of CO, NOx, and soot was studied by changing the Intake air temperature (IAT), Inflow droplet temperature (IDT), Start of injection (SOI), and Duration of injection (DOI).
