Considered to be a major contributor to greenhouse gas emissions, the transport sector's use of alternative fuels is a daunting and promising challenge to meet pollution limits and to protect the environment. The purpose of this chapter is to perform a comparatively experimental investigation of the emissions of nitrogen oxide (NOx) from an internal combustion engine, the engine is fueled by gasoline available in the Saudi Arabian market ranking octane number (RON 91 and RON 95) of syngas mixtures with 0 percent E0, 5 percent E5 and 10 percent E10 by volume of anhydrous ethanol and HE55 percent E5 and 10 percent E10 With water concentrations of 5%, 10%, 30% and 40% by volume of hydrous ethanol in the presence of the stoichiometric mixture regime, HE10 and HE10. An on-board plasma system used by the plasma-assisted fuel reformer for the processing of syngas (H2, CO, CO2) through the partial oxidation of gasoline with air. Syngas injected in a gasoline engine with a changed fuel injection system for service with some amount of syngas added. This research is a continuation of a previous study in which, in the presence of various ultra-lean mixture regimes, the engine was examined in terms of output and exhaust emissions where the engine was fueled by gasoline RON91/RON95, with an admixture of syngas and 5 percent by volume pure ethanol (E5). The experimental results showed a substantial overall decrease in NOx emissions and a small increase in fuel consumption when combining gasoline (RON 91 and RON 95), ethanol anhydrous (E5 and E10) and ethanol hydrous (HE5 and HE10) with syngas. For the inclusion of syngas, for the use of hydrous ethanol (HE5 and HE10). For both RON 91 and RON 95, 60 percent of the lowest NOx emissions in RON 91 and 72 percent in RON 95 were found at 40 percent water concentration in hydrous ethanol. For future work, we intend to investigate the impact on syngas yield and composition of the reformer plasmatorch design. We plan to change the plasmatorch anode and some other parts and then test the fuel reforming process output using these changed parts. With our engine test device, the best feasible configuration and design of the plasmatorch producing the highest hydrogen content in syngas will be used for further service.
