چکیده انگلیسی:
A numerical model based on thermodynamic and kinetic analyses has been established in order to eval- uate biogas, hydrogen, natural gas or liquid petroleum gas as fuels in a spark ignition engine. For each fuel type, consumption as well as efficiency have been compared to gasoline in order to generate the same engine work (in the range of 0.28–0.43 W h/cycle). It was found that the spark ignition engine can be fed by an equimolar mixture of biogas and hydrogen. Moreover, thermal efficiency has been enhanced with respect to fuel consumption and exhaust gas recirculation (EGR). It was shown that an equimolar mixture between biogas and hydrogen increases the ITE by around 2.2% and decreases the mass con- sumption by less than 0.01 g/cycle. In addition, the combustion reaction progresses as well as CO and CO2 emissions have been characterized in real time.© 2016 Elsevier Ltd. All rights reserved.
