As a combustion improver, a small amount of Brown gas flowed into the combustion chamber of a gasoline engine. Accordingly, the exhaust gas and fuel efficiency characteristics of the engine were analyzed. Brown gas has different properties from hydrogen. It is a completely non-polluting gas made from the electrolysis of water. It is a mixed gas with a hydrogen to oxygen ratio of 2:1, which is the same as that of water (H2O). Approximately 1,800 L of Brown gas can be obtained through the electrolysis of 1 L of water, and a thermal energy over 2,800 oC can be obtained through combustion. In this study, an experimental device was constructed in order to supply a small amount of Brown gas into the air entering the combustion chamber by connecting a Brown gas generator to the intake manifold of a gasoline engine. The characteristics of the exhaust gas and fuel efficiency according to the addition of Brown gas as a combustion accelerator were analyzed. Under the experimental conditions without changes in the power and torque of the engine, it was confirmed that the cumulative CO, NOx, and CO2 emissions decreased as the driving distance increased. Brown gas as a combustion accelerator induces lean combustion of the engine, from which it is analyzed as the reduction of CO and NOx emissions. The reduction of CO2 emissions is thought to be the result of improved fuel economy. |
