摘      要：This research work is the novel state-of-the-art technology performed on multi-cylinder SI engine fueled compressed natural gas,emulsified fuel,and hydrogen as dual *** work predicts the overall features of performance,combustion,and exhaust emissions of individual fuels based on AVL Boost simulation *** types of alternative fuels have been compared and *** results show that hydrogen produces 20%more brake power than CNG and 25%more power than micro-emulsion fuel at 1500 r/min,which further increases the brake power of hydrogen,CNG,and micro-emulsions in the range of 25%,20%,and 15%at higher engine speeds of 2500-4000 r/min,*** addition,the brake-specific fuel consumption is the lowest for 100%hydrogen,followed by CNG 100%and then micro-emulsions at 1500 r/*** 2500-5000 r/min,there is a significant drop in brake-specific fuel consumption due to a lean mixture at higher engine *** CO,HC,and NOx emissions significantly improve for hydrogen,CNG,and micro-emulsion *** fuel shows zero CO and HC emissions and is the main objective of this research to produce 0%carbon-based emissions with a slight increase in NOx emissions,and CNG shows 30%lower CO emissions than micro-emulsions and 21.5%less hydrocarbon emissions than micro-emulsion fuel at stoichiometric air/fuel ratio.
