Internal combustion engine efficiency enhancer by using hydrogen

Numerical simulation on the combustion and NOx emission characteristics of a turbocharged opposed rotary piston engine fuelled with hydrogen under wide open throttle conditions

“…The merits mentioned above make hydrogen as an excellent fuel for IC engine applications. Many researchers [23][24][25][26] were devoted to investigating and exploring high performance IC engines fuelled with hydrogen or its blends. Ganesh [27] compared the performance of a single cylinder reciprocating engine fuelled with gasoline and hydrogen.…”

Lean-burn characteristics of a turbocharged opposed rotary piston engine fuelled with hydrogen at low engine speed conditions

“…Hydrogen fuel applications in IC engines are developing rapidly because of their high thermal efficiency and being free of greenhouse gas emission (CO 2 ) [22,23]. High brake thermal efficiency was mainly caused by high flame propagation speed and quenching distances for pure hydrogen fuel [24,25] and hydrogen fuel addition in different types of fuel such as ethanol [26], natural gas [27], n-butanol [28], gasoline [11], and diesel [29].…”
