Fuel consumption and emissions from a vehicle operating with ethanol, gasoline and hydrogen produced on-board

An experimental study of a hydrogen-enriched ethanol fueled Wankel rotary engine at ultra lean and full load conditions

“…Moreover, hydrogen has a wider flammable mixture range and low ignition energy, a high diffusion rate and a significantly faster laminar burning velocity [17,30,32]. All of these characteristics are helpful to improve the combustion and reduce the quenching effect in the Wankel engine, [14,17,29,33]. In addition, hydrogen's combustion characteristics can improve the engine's lean burn capability [28][29][30]34].…”

Modeling of vehicle fuel consumption and carbon dioxide emission in road transport

“…Also, this model is suitable only for European vehicles [10]. Another study investigated fuel consumption and pollutant emissions from a vehicle operating with gasoline-ethanol blend, hydrous ethanol and hydrogen produced onboard and has shown that fuel consumption is reduced by using hydrogen fuel [11]. However, this study reported the experimental results for three fuels considering a specific type of vehicle.…”

“…However, this study reported the experimental results for three fuels considering a specific type of vehicle. Also, it does not consider different characteristics of the vehicle, road conditions and etc [11]. A parametric study was conducted with only gasoline and diesel vehicles by using the AVL 6 commercial program [12].…”

Control Scheme Formulation for the Production of Hydrogen on Demand to Feed an Internal Combustion Engine

“…The use of hydrogen to feed IC engines has environmental and economic advantages as is shown in the works presented by different authors [13][14][15][16][17]. On the one hand, different authors [16,17] have reported that, by using hydrogen, the CO and CO 2 in the exhaust gas emissions decrease.…”

“…On the one hand, different authors [16,17] have reported that, by using hydrogen, the CO and CO 2 in the exhaust gas emissions decrease. In relation to the NO x exhaust gas emissions, there are some experimental results in [14,15] where the authors made tests using a gasoline-hydrogen blend.…”
