Reduction of Pollutant for SI Engine Using Argon and Oxy-hydrogen
Abstract: Reducing the emission associated with oil combustion is gaining increasing interest worldwide. Due to their dangerous effects on human health, vegetation and climate, various pre-combustion, in-cylinder and post combustion techniques have been tried for their abatement. The combustion of a hydrocarbon fuel with air produces mainly carbon dioxide(CO2) and Water(H2O). However, internal combustion engines are not perfectly efficient, so some of the fuel is not burned, which results in the …
