Combined Effect of CNG and EGR on the Performance, Emission and Combustion Characteristics of Diesel Engine in Dual Fuel mode

Severe and adverse energy crises in future, day by day ever elevating cost of fuels, dangerous emissions emitted with conventional fuels made internal combustion engine scientists to discover and look at the likelihood of usage of alternate, clean and less or zero emissions fluids and vaporous fuels for IC engines, especially compression ignition diesel engines (DE) since existing DE are under stringent pollutions regulation that too for smoke and NOx in their tail pipe fumes. The main target of this work is to examine the emission, combustion and performance attributes of a diesel engine running with a wide range of loads with a constant speed of 1500rpm with a 30% steedy energy share of CNG and varying EGR of 5%,10% and 15% using diesel as pilot fuel. BSEC of dual fuel mode engine is discovered superior to neat diesel engine mode at higher load. It is discovered that there is an uncommon decrease in NOX, CO2, and smoke density, increment in UHC, CO in the fumes of dual fuel engine at all loads. Comparative results are given for dual fuel mode with variable measures of EGR at various loads conditions and detailed the impact of the application of EGR on combustion, performance and emission processes. © 2022.
