Renewable and alternative fuels have numerous advantages compared to fossil fuels as they are biodegradable, providing energy security and foreign exchange saving and addressing environmental concerns, and socio-economic issues as well. The present work is an effort in this direction and was conducted in two phases, in the first phase; solid waste from a local site was collected and separated combustible biomass. In the next phase of the work, the influence of hydrogen share on the performance, combustion and emission characteristics of diesel engine operation fueled with diesel and producer gas (PG)/Honge oil methyl ester (HOME) has been studied. Hydrogen (H-2) was inducted during suction stroke through the inlet manifold at varying flow rates ranging from 4 to 12 L per minute (1pm) in steps of 4 1pm. Experimental findings revealed that the addition of Hydrogen (H2) to low calorific value PG significantly affect the combustion and emission characteristics. Results of investigation showed H2 of 8 1pm induction resulted in improved brake thermal efficiency (BTE) by 5.5%, reduced carbon monoxide (CO), smoke, hydrocarbon (HC) emissions by 22-25% while nitric oxide (NOx) emissions increased by 15%. Peak pressure and HRR for the HOME-PG with H2 addition were increased by 15.6% and 20.4%, respectively compared to the DF operation without H2 addition. (C) 2016 Elsevier Ltd. All rights reserved.
