Abstract
In the last two decades, specific interest has been addressed towards Internal Combustion Engines (ICEs) powered by bio-fuels. The growing interest for bio-fuels is related to constantly increasing stringent exhaust gases regulations and to a remarkable request of reduction of CO2- emissions. In the same direction (CO2-emissions reduction) and, additionally with the aim to minimize the dependence from crude oil, several alternative fuels have gained attention in the automotive industry. The fuels of bio-origin can provide a feasible solution to worldwide petroleum crisis by promising a sustainable development, energy conservation and environmental preservation. Gasoline and diesel-driven engines are the major sources of Green- House Gases (GHG) emissions [1-3]. Scientists around the world have been explored several alternative energy sources including biomass derived fuels, biogas, primary alcohol, vegetable oils, biodiesel, etc. These alternative energy sources are largely environmental-friendly but their use needs further investigations in relation to the specific applications. Some of them can be used directly while others need to be formulated to bring their relevant properties closer to those of conventional fuels. This work deals with some features of spark ignition engines powered by syngas. The ENEA GRID Cresco resources have been used to perform accurate simulations using an advanced parallel CFD code.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
